营运管理 外文翻译 外文文献 对整个行业中营运资金管理的研究

外文资料翻译译文营运资本管理目前，随着我国市场经济的高速增长，以及逐步进行的金融改革，企业对于营运资本管理的重视程度与日俱增。

营运资本管理对于企业的经营发展具有至关重要的作用。

它是财务管理的组成部分，体现出了企业的财务管理和控制的水平，同时被认为是企业生存与发展的重要基础。

其重要性不言而喻。

主要描述了关于营运资本管理的相关理论和实践环境，简要说明了国内国外的在该领域所取得的成就。

而在此之后，正文部分从理论角度出发，首先简要说明了营运资本管理的相关定义。

由于我国在该领域的理论与实践经验不足，所以国内在该领域存在诸多问题，如流动资金缺乏，管理不力，运营效率低等。

本文就国内的现状以及存在的问题进行深入探讨，同时，分析其成因。

为了更具说服力，找到代表性的企业案例进行进一步的分析说明。

最后，提炼出解决企业营运资本管理问题的对策，为企业营运资本管理提供依据方法。

营运资金是企业资金结构中最具活力的部分，营运资金的运转效率很大程度上决定了企业的生存与发展。

从会计角度讲，营运资金是指某时点内企业的流动资产与流动负债的差额，构成要素包括现金、有价证券、应收账款、存货等。

这些要素的周转速度及资金占有余额直接影响着企业经营效益，又制约着企业的生产经营规模。

营运资本主要在研究企业的偿债能力和财务风险时使用。

如果营运资本过量，说明资产利用率不高；如果营运资本过少，说明固定资产投资依赖短期债务融资的程度较高，经营上会受到影响。

因此，营运资本管理是企业财务管理的重要组成部分。

然而，目前很多企业在营运资金管理方面存在很多问题，如资金营运能力较低、资金短缺，这些都严重影响到企业的经营效益。

因此解决好营运资金管理中存在的问题,有利于企业财务管理目标的实现。

我国中小企业从资金角度看，规模普遍较小，从市场抗风险能力看，抵御能力较弱，同时财务制度还不完善，财务管理水平相对落后，在经济市场大环境中，中小企业往往处于破产的风口浪尖上，此时财务管理显得尤为重要。

Research in International Business and Finance 32 (2014): 36-49.原文The impact of working capital management on firm profitability in different business cycles: Evidence from Finland1. IntroductionThis paper investigates the effect of the business cycle on the link between working capital, the difference between current assets and current liabilities, and corporate performance. Efficient working capital management is recognized as an important aspect of financial management practices in all organizational forms. In acknowledgement of this importance, the CFO Magazine publishes an annual study of corporate working capital management performance in many countries. The extensive literature indicates that it impacts directly on corporate liquidity ( Kim et al., 1998 and Opler et al., 1999), profitability (e.g., Shin and Soenen, 1998, Deloof, 2003, Lazaridis and Tryfonidis, 2006 and Ukaegbu, 2014), and solvency (e.g.,Berryman, 1983 and Peel and Wilson, 1994).It is reasonable to assume that economy-wide fluctuations exogenous to the operations of the firm play an important role in the demand for firms’ products and any financing decision. Korajczyk and Levy (2003), for instance, suggest that firms time debt issuance based on economic conditions. Also, given that retained earnings are a significant component of working capital, business cycles can be said to affect all enterprises financing source through its effect on economic growth and sales. For example, when company sales weaken it engenders earning declines, thereby, affecting an important source of working capital. The recent global economic downturn with crimping consumer demand is an excellent example of this. The crisis,characterized by plummeting sales, put a squeeze on corporate revenues and profit margins, and subsequently, working capital requirements. This has brought renewed focus on working capital management at companies all over the world.The literature on working capital, however, only includes a handful of studies examining the impact of the business cycle on working capital. An early study by Merville and Tavis (1973) examined the relationship between firm working capital policies and business cycle. More recent studies have investigated the degree to which firms’ reliance on bank borrowing to finance working capital is cyclical (Einarsson and Marquis, 2001), the significance of firms’ external dependence for financing needs on the link between industry growth and business the cycle in the short term (Braun and Larrain, 2005), and the influence of business indicators on the determinants of working capital management (Chiou et al., 2006). These studies have independently linked working capital to corporate profitability and the business cycle. No study, to the best of our knowledge, has examined the simultaneous working capital–profitability and business cycle effects. There is therefore a substantial gap in the literature which this paper seeks to fill. Firms may have an optimal level of working capital that maximizes their value. However, optimal levels may change to reflect business conditions. Consequently, we contribute to the literature by re-examining the relationship between working capital management and corporate profitability by investigating the role business cycle plays in this relationship.We investigate this important relationship using a sample of firms listed on the Helsinki Stock Exchange and an extended study period of 18 years, between 1990 and 2008. Finnish firms tend to react strongly to changes in the business cycle, a characteristic that can be observed from the volatility of the Nasdaq OMX Helsinki stock index. The index usually declines quickly in poor economic states, but also makes fast recoveries. Finland, therefore, presents an excellent representative example of how the working capital–profitability relationship may change in different economic states. The choice of Finland is also significant as it also offers a representative Nordic perspective of this important working capital–profitability relationship. Hitherto no academic study has examined the workingcapital–profitability relationship in the Nordic region, to the best of our knowledge. Surveys on working capital management in the Nordic region carried out by Danske Bank and Ernst & Young in 2009 show, however, that many companies rated their working capital management performance as average, with a growing focus on optimizing working capital in the future. The surveys are, however, silent on how this average performance affected profitability. This gives further impetus for our study.Our results point to a number of interesting findings. First, we find that firms can enhance their profitability by increasing working capital efficiency. This is a significant result because many Nordic firms find it hard to turn good policy intentions on working capital management into reality (Ernst and Young, 2009). Economically, firms may gain by paying increasing attention to efficient working capital practices. Our empirical finding, therefore, should motivate firms to implement new work processes as a matter of necessity. We also found that working capital management is relatively more important in low economic states than in the economic boom state, implying working capital management should be included in firms’ financial planning. This finding corroborates evidence from the survey results in the Nordic region. Specifically, the survey results by Ernst and Young (2009) indicate that the largest potential for improvement in working capital could be found within the optimization of internal processes. This suggests that this area is not prioritized in times of business growth which is typical of the general economic expansion periods and is exposed in economic downturns.The remainder of this paper is organized as follows: Section 2 presents a brief review of the literature presents the hypotheses for empirical testing. Sections 3 and 4 discuss data and models to be estimated. The empirical results are presented in Section 5 and Section 6 concludes.2. Related literature and hypotheses2.1. Literature reviewMany firms have invested significant amounts in working capital and a number of studies have examined the determinants of this investment. For example Kim et al. (1998) and Opler et al. (1999), Chiou et al. (2006) and D’Mello et al. (2008) find thatthe availability of external financing is a determinant of liquidity. Thus restricted access to capital markets requires firms to hold larger cash reserves. Other studies show that firms with weaker corporate governance structures hold smaller cash reserves (Harford et al., 2008). Furthermore firms with excess cash holding as well as weak shareholder rights undertake more acquisitions. However there is a higher likelihood of value-decreasing acquisitions (Harford, 1999). Kieschnick and Laplante (2012) provide evidence linking working capital management to shareholder wealth. They find that the incremental dollar invested in net operating capital is less valuable than the incremental dollar held in cash for the average firm. The findings reported in the paper further suggest that the valuation of the incremental dollar invested in net operating working is significantly influenced by a firm's future sales expectations, its debt load, its financial constraints, and its bankruptcy risk. Further the value of the incremental dollar extended in credit to one's customers has a greater effect on shareholder wealth than the incremental dollar invested in inventories for the average firm. Taken together the results indicate the significance of working capital management to the firm's residual claimants, and how financing impacts these effects.A thin thread of the literature links business cycles to working capital. In a theoretical model, Merville and Tavis (1973) posit that investment and financing decisions relating to working capital should be made in chorus as components of each impact on the optimal policies of the others. The optimal working capital policy of the firm is, therefore, made within a systems context, components of which are related spatially over time in a chance-constrained format. Uncertainty in the wider business environment directly affects the system. For example, short run demand fluctuations disrupt anticipated incoming cash flows, and the collection of receivables faces increased uncertainty. The model provides a structure enabling corporate managers to solve complex inventory and credit policies for short term financial planning.In an empirical study, Einarsson and Marquis (2001) find that the degree to which companies rely on bank financing to cover their working capital requirements in the U.S. is countercyclical; it increases as the state of the economy weakens. Furthermore, Braun and Larrain (2005) find that high working capital requirementsar e a key determinant of a business’ dependence on external financing. They show that firms that are highly dependent on external financing are more affected by recessions, and should take more precautions in preparing for declines in the economic environment, including ensuring a secure level of working capital reserves during times of crisis. Additionally, Chiou et al. (2006) recognize the importance of the state of the economy and includes business indicators in their study of working capital determinants. They find a positive relationship between business indicator and working capital requirements.The relationship between profitability and working capital management in various markets has also attracted intense interest. In a comprehensive study, Shin and Soenen (1998) document a strong inverse relationship between working capital efficiency and profitability across U.S. industries. This inverse relationship is supported by Deloof (2003), Lazaridis and Tryfonidis (2006), and Garcia-Teruel and Martinez-Solano (2007)for Belgian non-financial firms, Greek listed firms, and Spanish small and medium size enterprises (SME), respectively. There are, however, significant divergences in the results relating to the effect of the various components of working capital on profitability. For example, whereas Deloof (2003) find a negative and statistically significant relationship between account payable and profitability, Garcia-Teruel and Martinez-Solano (2007) find no such measurable influences in a sample of Spanish SMEs.2.2. Hypotheses developmentThe cash conversion cycle (CCC), a useful and comprehensive measure of working capital management, has been widely used in the literature (see for example Deloof, 2003 and Gill et al., 2010). The CCC, measured in days, is the length of time between a company's expenditure for the procurement of raw materials and the collection of sales of finished goods. We adopt this as our measure of working capital management in this study. Previous studies have established a link between profitability and the CCC in different countries and market segments.Efficient working capital management practices aims to shorten the CCC to optimize to levels that best suites the requirements of the specific company (Hager,1976). A short CCC indicates quick collection of receivables and delays in payments to suppliers. This is associated with profitability given that it improves corporate efficiency in its use of working capital. Deloof (2003), however, posits that low inventory levels, tight trade credit policies and utilizing obtained trade credit as a means of financing can increase risks of inventory stock-outs, decrease sales stimulants and increase accounts payable costs by forgoing given cash discounts. Managers must, therefore, always consider the tradeoff between liquidity and profitability when managing working capital. A faster rise in the cost of higher investment in working capital relative to the benefits of holding more inventories and/or granting trade credit to customers may lead to decrease in corporate profitability. Deloof (2003), Wang (2002), Lazaridis and Tryfonidis (2006), and Gill et al. (2010) all propose a negative relationship between the cash conversion cycle and corporate profitability. Following this, we propose a general hypothesis stating the expected negative relationship between the cash conversion cycle and corporate profitability:6. ConclusionsWorking capital, the difference between current assets and current liabilities, is used to fund a business’ daily operations due to t he time lag between buying raw materials for production and receiving funds from the sale of the final product. With vast amounts invested in working capital, it can be expected that the management of these assets would significantly affect the profitability of a company. Consequently, companies strive to achieve optimize levels of working capital by paying bills as late as possible, turning over inventories quickly, and collecting on account receivables quickly. The optimal level, though, may vary to reflect business conditions. This study examines the role business cycle plays in the working capital-corporate profitability relationship using a sample of Finnish listed companies from years 1990 to 2008.We utilize the cash conversion cycle (CCC), defined as the length of time between a company's expenditure for the procurement of raw materials and the collection of sales of finished goods, as our measure of working capital. We further make use of 2 measures of profitability, return on assets and gross operating income.We document a negative relationship between cash conversion cycle and corporate profitability. Our results also show that companies can achieve higher profitability levels by managing inventories efficiently and lowering accounts receivable collection times. Furthermore shorter account payable cycles enhance corporate profitability. These results, which largely mirror findings from other countries, indicate effective management of firm's total working capital as well as its individual components has a significant effect on corporate profitability levels.Our results also show that economic conditions exhibit measurable influences on the working capital-profitability relationship. The low economic state is generally found to have negative effects on corporate profitability. In particular, we find that the impact of efficient working capital (CCC) on operational profitability increases in economic downturns. We also find that the impact of efficient inventory management and accounts receivables conversion periods, subsets of CCC, on profitability increase in economic downturns.Overall the results indicate that investing in working capital processes and incorporating working capital efficiency into everyday routines is essential for corporate profitability. As a result, firms should include working capital management in their financial planning processes. Additionally, firms generate income and employment. The reduced demand in economic downturns depletes working capital of firms and threatens their stability and, implicitly, their important function as generators of employment and income. National economic policy aimed at boosting cash flows of firms may increase business ability to finance working capital internally, especially during economic down turns.译文营运资本管理对不同商业周期公司盈利能力的影响：证据来自芬兰1.引言本文研究商业周期与营运资本两者之间的联系,流动资产和流动负债之间的区别,以及公司业绩问题。

外文翻译原文：An Analysis of Working Capital Management Results AcrossIndustriesAbstractFirms are able to reduce financing costs and/or increase the funds available for expansion by minimizing the amount of funds tied up in current assets. We provide insights into the performance of surveyed firms across key components of working capital management by using the CFO magazine’s annual Working Capital Management Survey. We discover that significant differences exist between industries in working capital measures across time. In addition. we discover that these measures for working capital change significantly within industries across time. IntroductionThe importance of efficient working capital management is indisputable. Working capital is the difference between resources in cash or readily convertible into cash (Current Assets) and organizational commitments for which cash will soon be required (Current Liabilities). The objective of working capital management is to maintain the optimum balance of each of the working capital components. Business viability relies on the ability to effectively manage receivables. inventory. and payables. Firms are able to reduce financing costs and/or increase the funds available for expansion by minimizing the amount of funds tied up in current assets. Much managerial effort is expended in bringing non-optimal levels of current assets and liabilities back toward optimal levels. An optimal level would be one in which a balance is achieved between risk and efficiency.A recent example of business attempting to maximize working capital management is the recurrent attention being given to the application of Six Sigma® methodology. Six Sigma® methodologies help companies measure and ensure quality in all areas of the enterprise. When used to identify and rectify discrepancies.inefficiencies and erroneous transactions in the financial supply chain. Six Sigma® reduces Days Sales Outstanding (DSO). accelerates the payment cycle. improves customer satisfaction and reduces the necessary amount and cost of working capital needs. There appear to be many success stories. including Jennifer Towne’s (2002) report of a 15 percent decrease in days that sales are outstanding. resulting in an increased cash flow of approximately $2 million at Thibodaux Regional Medical Center. Furthermore. bad debts declined from $3.4 million to $600.000. However. Waxer’s (2003) study of multiple firms employing Six Sigma® finds that it is really a “get rich slow” technique with a rate of return hovering in the 1.2 – 4.5 percent range. Even in a business using Six Sigma® methodology. an “optimal” level of working capital management needs to be identified.Even in a business using Six Sigma® methodology. an “optimal” level of working capital management needs to be identified. Industry factors may impact firm credit policy. inventory management. and bill-paying activities. Some firms may be better suited to minimize receivables and inventory. while others maximize payables. Another aspect of “optimal” is the extent to which poor financial results can be tied to sub-optimal performance. Fortunately. these issues are testable with data published by CFO magazine. which claims to be the source of “tools and information for the financial executive.” and are the sub ject of this research.In addition to providing mean and variance values for the working capital measures and the overall metric. two issues will be addressed in this research. One research question is. “are firms within a particular industry clustered to gether at consistent levels of working capital measures?” For instance. are firms in one industry able to quickly transfer sales into cash. while firms from another industry tend to have high sales levels for the particular level of inventory . The other research question is. “does working capital management performance for firms within a given industry change from year-to-year?”The following section presents a brief literature review. Next. the research method is described. including some information about the annual Working CapitalManagement Survey published by CFO magazine. Findings are then presented and conclusions are drawn.Related LiteratureThe importance of working capital management is not new to the finance literature. Over twenty years ago. Largay and Stickney (1980) reported that the then-recent bankruptcy of W.T. Grant. a nationwide chain of department stores. should have been anticipated because the corporation had been running a deficit cash flow from operations for eight of the last ten years of its corporate life. As part of a study of the Fortune 500’s financial management practices. Gilbert and Reichert (1995) find that accounts receivable management models are used in 59 percent of these firms to improve working capital projects. while inventory management models were used in 60 percent of the companies. More recently. Farragher. Kleiman and Sahu (1999) find that 55 percent of firms in the S&P Industrial index complete some form of a cash flow assessment. but did not present insights regarding accounts receivable and inventory management. or the variations of any current asset accounts or liability accounts across industries. Thus. mixed evidence exists concerning the use of working capital management techniques.Theoretical determination of optimal trade credit limits are the subject of many articles over the years (e.g.. Schwartz 1974; Scherr 1996). with scant attention paid to actual accounts receivable management. Across a limited sample. Weinraub and Visscher (1998) observe a tendency of firms with low levels of current ratios to also have low levels of current liabilities. Simultaneously investigating accounts receivable and payable issues. Hill. Sartoris. and Ferguson (1984) find differences in the way payment dates are defined. Payees define the date of payment as the date payment is received. while payers view payment as the postmark date. Additional WCM insight across firms. industries. and time can add to this body of research.Maness and Zietlow (2002. 51. 496) presents two models of value creation that incorporate effective short-term financial management activities. However. these models are generic models and do not consider unique firm or industry influences. Maness and Zietlow discuss industry influences in a short paragraph that includes theobservation that. “An industry a company is located in may have more influence on that company’s fortunes than overall GNP” (2002. 507). In fact. a careful review of this 627-page textbook finds only sporadic information on actual firm levels of WCM dimensions. virtually nothing on industry factors except for some boxed items with titles such as. “Should a Retailer Offer an In-House Credit Card” (128) and nothing on WCM stability over time. This research will attempt to fill this void by investigating patterns related to working capital measures within industries and illustrate differences between industries across time.An extensive survey of library and Internet resources provided very few recent reports about working capital management. The most relevant set of articles was Weisel and Bradley’s (2003) article on cash flow management and one of inventory control as a result of effective supply chain management by Hadley (2004). Research MethodThe CFO RankingsThe first annual CFO Working Capital Survey. a joint project with REL Consultancy Group. was published in the June 1997 issue of CFO (Mintz and Lezere 1997). REL is a London. England-based management consulting firm specializing in working capital issues for its global list of clients. The original survey reports several working capital benchmarks for public companies using data for 1996. Each company is ranked against its peers and also against the entire field of 1.000 companies. REL continues to update the original information on an annual basis.REL uses the “cash flow from operations” value located on firm cash flow statements to estimate cash conversion efficiency (CCE). This value indicates how well a company transforms revenues into cash flow. A “days of working capital” (DWC) value is based on the dollar amount in each of the aggregate. equally-weighted receivables. inventory. and payables accounts. The “days of working capital” (DNC) represents the time period between purchase of inventory on acccount from vendor until the sale to the customer. the collection of the receivables. and payment receipt. Thus. it reflects the company’s ability to finance its core operations with vendor credit. A detailed investigation of WCM is possible becauseCFO also provides firm and industry values for days sales outstanding (A/R). inventory turnover. and days payables outstanding (A/P).Research FindingsAverage and Annual Working Capital Management Performance Working capital management component definitions and average values for the entire 1996 –2000 period . Across the nearly 1.000 firms in the survey. cash flow from operations. defined as cash flow from operations divided by sales and referred to as “cash conversion efficiency” (CCE). averages 9.0 percent. Incorporating a 95 percent confidence interval. CCE ranges from 5.6 percent to 12.4 percent. The days working capital (DWC). defined as the sum of receivables and inventories less payables divided by daily sales. averages 51.8 days and is very similar to the days that sales are outstanding (50.6). because the inventory turnover rate (once every 32.0 days) is similar to the number of days that payables are outstanding (32.4 days). In all instances. the standard deviation is relatively small. suggesting that these working capital management variables are consistent across CFO reports.Industry Rankings on Overall Working Capital Management Performance CFO magazine provides an overall working capital ranking for firms in its survey. using the following equation: Industry-based differences in overall working capital management are presented for the twenty-six industries that had at least eight companies included in the rankings each year. In the typical year. CFO magazine ranks 970 companies during this period. Industries are listed in order of the mean overall CFO ranking of working capital performance. Since the best average ranking possible for an eight-company industry is 4.5 (this assumes that the eight companies are ranked one through eight for the entire survey). it is quite obvious that all firms in the petroleum industry must have been receiving very high overall working capital management rankings. In fact. the petroleum industry is ranked first in CCE and third in DWC (as illustrated in Table 5 and discussed later in this paper). Furthermore. the petroleum industry had the lowest standard deviation of working capital rankings and range of working capital rankings. The only other industry with a mean overall ranking less than 100 was the Electric & Gas Utility industry. which ranked second inCCE and fourth in DWC. The two industries with the worst working capital rankings were Textiles and Apparel. Textiles rank twenty-second in CCE and twenty-sixth in DWC. The apparel industry ranks twenty-third and twenty-fourth in the two working capital measuresConclusionsThe research presented here is based on the annual ratings of working capital management published in CFO magazine. Our findings indicate a consistency in how industries “stack up” against each other over time with respe ct to the working capital measures. However. the working capital measures themselves are not static (i.e.. averages of working capital measures across all firms change annually); our results indicate significant movements across our entire sample over time. Our findings are important because they provide insight to working capital performance across time. and on working capital management across industries. These changes may be in explained in part by macroeconomic factors. Changes in interest rates. rate of innovation. and competition are likely to impact working capital management. As interest rates rise. there would be less desire to make payments early. which would stretch accounts payable. accounts receivable. and cash accounts.The ramifications of this study include the finding of distinct levels of WCM measures for different industries. which tend to be stable over time. Many factors help to explain this discovery. The improving economy during the period of the study may have resulted in improved turnover in some industries. while slowing turnover may have been a signal of troubles ahead. Our results should be interpreted cautiously. Our study takes places over a short time frame during a generally improving market. In addition. the survey suffers from survivorship bias – only the top firms within each industry are ranked each year and the composition of those firms within the industry can change annually.Source: Thomas M.

Research in International Business and Finance 32 (2014): 36-49.原文The impact of working capital management on firm profitability in different business cycles: Evidence from Finland1. IntroductionThis paper investigates the effect of the business cycle on the link between working capital, the difference between current assets and current liabilities, and corporate performance. Efficient working capital management is recognized as an important aspect of financial management practices in all organizational forms. In acknowledgement of this importance, the CFO Magazine publishes an annual study of corporate working capital management performance in many countries. The extensive literature indicates that it impacts directly on corporate liquidity ( Kim et al., 1998 and Opler et al., 1999), profitability (e.g., Shin and Soenen, 1998, Deloof, 2003, Lazaridis and Tryfonidis, 2006 and Ukaegbu, 2014), and solvency (e.g.,Berryman, 1983 and Peel and Wilson, 1994).It is reasonable to assume that economy-wide fluctuations exogenous to the operations of the firm play an important role in the demand for firms’ products and any financing decision. Korajczyk and Levy (2003), for instance, suggest that firms time debt issuance based on economic conditions. Also, given that retained earnings are a significant component of working capital, business cycles can be said to affect all enterprises financing source through its effect on economic growth and sales. For example, when company sales weaken it engenders earning declines, thereby, affecting an important source of working capital. The recent global economic downturn with crimping consumer demand is an excellent example of this. The crisis,characterized by plummeting sales, put a squeeze on corporate revenues and profit margins, and subsequently, working capital requirements. This has brought renewed focus on working capital management at companies all over the world.The literature on working capital, however, only includes a handful of studies examining the impact of the business cycle on working capital. An early study by Merville and Tavis (1973) examined the relationship between firm working capital policies and business cycle. More recent studies have investigated the degree to which firms’ reliance on bank borrowing to finance working capital is cyclical (Einarsson and Marquis, 2001), the significance of firms’ external dependence for financing needs on the link between industry growth and business the cycle in the short term (Braun and Larrain, 2005), and the influence of business indicators on the determinants of working capital management (Chiou et al., 2006). These studies have independently linked working capital to corporate profitability and the business cycle. No study, to the best of our knowledge, has examined the simultaneous working capital–profitability and business cycle effects. There is therefore a substantial gap in the literature which this paper seeks to fill. Firms may have an optimal level of working capital that maximizes their value. However, optimal levels may change to reflect business conditions. Consequently, we contribute to the literature by re-examining the relationship between working capital management and corporate profitability by investigating the role business cycle plays in this relationship.We investigate this important relationship using a sample of firms listed on the Helsinki Stock Exchange and an extended study period of 18 years, between 1990 and 2008. Finnish firms tend to react strongly to changes in the business cycle, a characteristic that can be observed from the volatility of the Nasdaq OMX Helsinki stock index. The index usually declines quickly in poor economic states, but also makes fast recoveries. Finland, therefore, presents an excellent representative example of how the working capital–profitability relationship may change in different economic states. The choice of Finland is also significant as it also offers a representative Nordic perspective of this important working capital–profitability relationship. Hitherto no academic study has examined the workingcapital–profitability relationship in the Nordic region, to the best of our knowledge. Surveys on working capital management in the Nordic region carried out by Danske Bank and Ernst & Young in 2009 show, however, that many companies rated their working capital management performance as average, with a growing focus on optimizing working capital in the future. The surveys are, however, silent on how this average performance affected profitability. This gives further impetus for our study.Our results point to a number of interesting findings. First, we find that firms can enhance their profitability by increasing working capital efficiency. This is a significant result because many Nordic firms find it hard to turn good policy intentions on working capital management into reality (Ernst and Young, 2009). Economically, firms may gain by paying increasing attention to efficient working capital practices. Our empirical finding, therefore, should motivate firms to implement new work processes as a matter of necessity. We also found that working capital management is relatively more important in low economic states than in the economic boom state, implying working capital management should be included in firms’ financial planning. This finding corroborates evidence from the survey results in the Nordic region. Specifically, the survey results by Ernst and Young (2009) indicate that the largest potential for improvement in working capital could be found within the optimization of internal processes. This suggests that this area is not prioritized in times of business growth which is typical of the general economic expansion periods and is exposed in economic downturns.The remainder of this paper is organized as follows: Section 2 presents a brief review of the literature presents the hypotheses for empirical testing. Sections 3 and 4 discuss data and models to be estimated. The empirical results are presented in Section 5 and Section 6 concludes.2. Related literature and hypotheses2.1. Literature reviewMany firms have invested significant amounts in working capital and a number of studies have examined the determinants of this investment. For example Kim et al. (1998) and Opler et al. (1999), Chiou et al. (2006) and D’Mello et al. (2008) find thatthe availability of external financing is a determinant of liquidity. Thus restricted access to capital markets requires firms to hold larger cash reserves. Other studies show that firms with weaker corporate governance structures hold smaller cash reserves (Harford et al., 2008). Furthermore firms with excess cash holding as well as weak shareholder rights undertake more acquisitions. However there is a higher likelihood of value-decreasing acquisitions (Harford, 1999). Kieschnick and Laplante (2012) provide evidence linking working capital management to shareholder wealth. They find that the incremental dollar invested in net operating capital is less valuable than the incremental dollar held in cash for the average firm. The findings reported in the paper further suggest that the valuation of the incremental dollar invested in net operating working is significantly influenced by a firm's future sales expectations, its debt load, its financial constraints, and its bankruptcy risk. Further the value of the incremental dollar extended in credit to one's customers has a greater effect on shareholder wealth than the incremental dollar invested in inventories for the average firm. Taken together the results indicate the significance of working capital management to the firm's residual claimants, and how financing impacts these effects.A thin thread of the literature links business cycles to working capital. In a theoretical model, Merville and Tavis (1973) posit that investment and financing decisions relating to working capital should be made in chorus as components of each impact on the optimal policies of the others. The optimal working capital policy of the firm is, therefore, made within a systems context, components of which are related spatially over time in a chance-constrained format. Uncertainty in the wider business environment directly affects the system. For example, short run demand fluctuations disrupt anticipated incoming cash flows, and the collection of receivables faces increased uncertainty. The model provides a structure enabling corporate managers to solve complex inventory and credit policies for short term financial planning.In an empirical study, Einarsson and Marquis (2001) find that the degree to which companies rely on bank financing to cover their working capital requirements in the U.S. is countercyclical; it increases as the state of the economy weakens. Furthermore, Braun and Larrain (2005) find that high working capital requirementsar e a key determinant of a business’ dependence on external financing. They show that firms that are highly dependent on external financing are more affected by recessions, and should take more precautions in preparing for declines in the economic environment, including ensuring a secure level of working capital reserves during times of crisis. Additionally, Chiou et al. (2006) recognize the importance of the state of the economy and includes business indicators in their study of working capital determinants. They find a positive relationship between business indicator and working capital requirements.The relationship between profitability and working capital management in various markets has also attracted intense interest. In a comprehensive study, Shin and Soenen (1998) document a strong inverse relationship between working capital efficiency and profitability across U.S. industries. This inverse relationship is supported by Deloof (2003), Lazaridis and Tryfonidis (2006), and Garcia-Teruel and Martinez-Solano (2007)for Belgian non-financial firms, Greek listed firms, and Spanish small and medium size enterprises (SME), respectively. There are, however, significant divergences in the results relating to the effect of the various components of working capital on profitability. For example, whereas Deloof (2003) find a negative and statistically significant relationship between account payable and profitability, Garcia-Teruel and Martinez-Solano (2007) find no such measurable influences in a sample of Spanish SMEs.2.2. Hypotheses developmentThe cash conversion cycle (CCC), a useful and comprehensive measure of working capital management, has been widely used in the literature (see for example Deloof, 2003 and Gill et al., 2010). The CCC, measured in days, is the length of time between a company's expenditure for the procurement of raw materials and the collection of sales of finished goods. We adopt this as our measure of working capital management in this study. Previous studies have established a link between profitability and the CCC in different countries and market segments.Efficient working capital management practices aims to shorten the CCC to optimize to levels that best suites the requirements of the specific company (Hager,1976). A short CCC indicates quick collection of receivables and delays in payments to suppliers. This is associated with profitability given that it improves corporate efficiency in its use of working capital. Deloof (2003), however, posits that low inventory levels, tight trade credit policies and utilizing obtained trade credit as a means of financing can increase risks of inventory stock-outs, decrease sales stimulants and increase accounts payable costs by forgoing given cash discounts. Managers must, therefore, always consider the tradeoff between liquidity and profitability when managing working capital. A faster rise in the cost of higher investment in working capital relative to the benefits of holding more inventories and/or granting trade credit to customers may lead to decrease in corporate profitability. Deloof (2003), Wang (2002), Lazaridis and Tryfonidis (2006), and Gill et al. (2010) all propose a negative relationship between the cash conversion cycle and corporate profitability. Following this, we propose a general hypothesis stating the expected negative relationship between the cash conversion cycle and corporate profitability:6. ConclusionsWorking capital, the difference between current assets and current liabilities, is used to fund a business’ daily operations due to t he time lag between buying raw materials for production and receiving funds from the sale of the final product. With vast amounts invested in working capital, it can be expected that the management of these assets would significantly affect the profitability of a company. Consequently, companies strive to achieve optimize levels of working capital by paying bills as late as possible, turning over inventories quickly, and collecting on account receivables quickly. The optimal level, though, may vary to reflect business conditions. This study examines the role business cycle plays in the working capital-corporate profitability relationship using a sample of Finnish listed companies from years 1990 to 2008.We utilize the cash conversion cycle (CCC), defined as the length of time between a company's expenditure for the procurement of raw materials and the collection of sales of finished goods, as our measure of working capital. We further make use of 2 measures of profitability, return on assets and gross operating income.We document a negative relationship between cash conversion cycle and corporate profitability. Our results also show that companies can achieve higher profitability levels by managing inventories efficiently and lowering accounts receivable collection times. Furthermore shorter account payable cycles enhance corporate profitability. These results, which largely mirror findings from other countries, indicate effective management of firm's total working capital as well as its individual components has a significant effect on corporate profitability levels.Our results also show that economic conditions exhibit measurable influences on the working capital-profitability relationship. The low economic state is generally found to have negative effects on corporate profitability. In particular, we find that the impact of efficient working capital (CCC) on operational profitability increases in economic downturns. We also find that the impact of efficient inventory management and accounts receivables conversion periods, subsets of CCC, on profitability increase in economic downturns.Overall the results indicate that investing in working capital processes and incorporating working capital efficiency into everyday routines is essential for corporate profitability. As a result, firms should include working capital management in their financial planning processes. Additionally, firms generate income and employment. The reduced demand in economic downturns depletes working capital of firms and threatens their stability and, implicitly, their important function as generators of employment and income. National economic policy aimed at boosting cash flows of firms may increase business ability to finance working capital internally, especially during economic down turns.译文营运资金管理对不同商业周期公司盈利能力的影响：证据来自芬兰1.引言本文研究商业周期与营运资本两者之间的联系,流动资产和流动负债之间的区别,以及公司业绩问题。

中小企业有效的营运资金管理摘要：中小企业（SME）的主要有效流动资金管理的需求对中小企业的偿付能力和流动性仍然至关重要。

大多数中小企业不关心他们的流动资金状况，大多数人很少考虑到他们的流动资金状况，这些企业大多数都没有标准的信贷政策。

许多人不关心他们的财务状况，他们只是经营，他们主要关注现金收据和他们的银行账户。

本研究使用标准流动资金比率来衡量所选企业的流动资金的有效性，所选择的公司显示过度交易和流动性不足的迹象，关注的是利润最大化，而没有认识到债权人的支付，这些公司的债务回报率低于信贷支付。

An Analysis of Working Capital Management Resultsacross IndustriesGreg Filbeck and Thomas M. KruegerAbstractFirms are able to reduce financing costs and/or increase the funds available for expansion by minimizing the amount of funds tied up in current assets. We provide insights into the performance of surveyed firms across key components of working capital management by using the CFO magazine’s annual Working Capital Management Survey. We discover that significant differences exist between industries in working capital measures across time. In addition, we discover that these measures for working capital change significantly within industries across time.IntroductionThe importance of efficient working capital management is indisputable. Working capital is the difference between resources in cash or readily convertible into cash (Current Assets) and organizational commitments for which cash will soon be required (Current Liabilities). The objective of working capital management is to maintain the optimum balance of each of the working capital components. Business viability relies on the ability to effectively manage receivables, inventory, and payables. Firms are able to reduce financing costs and/or increase the funds available for expansion by minimizing the amount of funds tied up in current assets. Much managerial effort is expended in bringing non-optimal levels of current assets and liabilities back toward optimal levels. An optimal level would be one in which a balance is achieved between risk and efficiency.A recent example of business attempting to maximize working capital management is the recurrent attention being given to the application of Six Sigma® methodology. Six Sigma® methodologies help companies measure and ensure quality in all areas of the enterprise. When used to identify and rectify discrepancies, inefficiencies and erroneous transactions in the financial supply chain. Six Sigma® reduces Days Sales Outstanding(DSO)，accelerates the payment cycle, improves customer satisfaction and reduces the necessary amount and cost of working capital needs. There appear to be many success stories, including Jennifer Towne’s (2002) report of a 15 percent decrease in days that sales are outstanding, resulting in an increased cash flow of approximately $2 million at Thibodaux Regional Medical Center. Furthermore, bad debts declined from $3.4 million to $600.000. However, Waxer’s (2003) study of multiple firms employing Six Sigma® find s that it is really a “get rich slow” technique with a rate of return hovering in the 1.2 – 4.5 percent range.Even in a business using Six Sigma® methodology, an “optimal” level of working capital management needs to be identified. Industry factors may impact firm credit policy, inventory management and bill-paying activities. Some firms may be better suited to minimize receivables and inventory, while others maximize payables. Another aspect of “optimal” is the extent to which poor financial results can be tied to sub-optimal performance. Fortunately, these issues are testable with data published by CFO magazine, which claims to be the source of “tools and information for the financial executive.” and are the subject of this research.In addition to providing mean and variance values for the working capital measures and the overall metric, two issues will be addressed in this research. One research question is “are firms within a particular industry clustered together at consistent levels of working capi tal measures?” For instance, are firms in one industry able to quickly transfer sales into cash, while firms from another industry tend to have high sales levels for the particular level of inventory. Th e other research question is “D oes working capital management performance for firms within a given industry change from year-to-year?”The following section presents a brief literature review. Next, the research method is described, including some information about the annual Working Capital Management Survey published by CFO magazine. Findings are then presented and conclusions are drawn.Related Literature第2页（共6页）The importance of working capital management is not new to the finance literature. Over twenty years ago, Largay and Stickney (1980) reported that the then-recent bankruptcy of W.T. Grant, a nationwide chain of department stores, should have been anticipated because the corporation had been running a deficit cash flow from operations for eight of the last ten years of its corporate life. As part of a stu dy of the Fortune 500’s financial management practices, Gilbert and Reichert (1995) find that accounts receivable management models are used in 59 percent of these firms to improve working capital projects, while inventory management models were used in 60 percent of the companies. More recently, Farragher, Kleiman and Sahu (1999) find that 55 percent of firms in the S&P Industrial index complete some form of a cash flow assessment, but did not present insights regarding accounts receivable and inventory management, or the variations of any current asset accounts or liability accounts across industries. Thus, mixed evidence exists concerning the use of working capital management techniques.Theoretical determination of optimal trade credit limits are the subject of many articles over the years (e.g. Schwartz 1974; Scherr 1996) with scant attention paid to actual accounts receivable management. Across a limited sample, Weinraub and Visscher (1998) observe a tendency of firms with low levels of current ratios to also have low levels of current liabilities. Simultaneously investigating accounts receivable and payable issues. Hill·Sartoris and Ferguson (1984) find differences in the way payment dates are defined. Payees define the date of payment as the date payment is received, while payors view payment as the postmark date. Additional WCM insight across firms, industries and time can add to this body of research.Maness and Zietlow (2002. 51. 496) presents two models of value creation that incorporate effective short-term financial management activities. However, these models are generic models and do not consider unique firm or industry influences. Maness and Zietlow discuss industry influences in a short paragraph that includes the observation that “An industry a company is located in may have more influence on that company’s fortunes than ov erall GNP” (2002. 507). In fact, a careful review of this 627-page textbook finds only sporadic information on actual firm levels of WCM dimensions, virtually nothing on第3页（共6页）industry factors except for some boxed items with titles such as “Should a Retailer Offer an In-House Credit Card” (128) and nothing on WCM stability over time. This researchwill attempt to fill this void by investigating patterns related to working capital measures within industries and illustrate differences between industries across time.An extensive survey of library and Internet resources provided very few recent reports about working capital management. The most relevant set of articles was Weisel and Bradley’s (2003) article on cash flow management and one of inventory control as a result of effective supply chain management by Hadley (2004).Research MethodThe first annual CFO Working Capital Survey, a joint project with REL Consultancy Group, was published in the June 1997 issue of CFO (Mintz and Lezere 1997). REL is a London, England-based management consulting firm specializing in working capital issues for its global list of clients. The original survey reports several working capital benchmarks for public companies using data for 1996. Each company is ranked against its peers and also against the entire field of 1000 companies. REL continues to update the original information on an annual basis.REL uses the “cash flow from operations” value l ocated on firm cash flow statements to estimate cash conversion efficiency (CCE). This value indicates how well a company transforms revenues into cash flow. A “days of working capital” (DWC) value is based on the dollar amount in each of the aggregate, equally-weighted receivables, inventory and payables accounts. T he “days of working capital” (D WC) represents the time period between purchases of inventory on account from vendor until the sale to the customer, the collection of the receivables and payment receipt. Thus, it reflects the company’s ability to finance its core operations with vendor credit. A detailed investigation of WCM is possible because CFO also provides firm and industry values for days sales outstanding (A/R), inventory turnover and days payables outstanding (A/P).Research Findings：Average and Annual Working Capital Management Performance Working capital management component definitions and average values for the entire 1996 – 2000 period. Across the nearly 1.000 firms in the survey, cash flow from operations,第4页（共6页）defined as cash flow from operations divided by sales and referred to as “ca sh conversion efficiency” (CCE). Averages 9.0 percent. Incorporating a 95 percent confidence interval, CCE ranges from 5.6 percent to 12.4 percent. The day’s working capital (DWC), defined as the sum of receivables and inventories less payables divided by daily sales, averages 51.8 days and is very similar to the days that sales are outstanding (50.6). Because the inventory turnover rate (once every 32.0 days) is similar to the number of days that payables are outstanding (32.4 days). In all instances, the standard deviation is relatively small, suggesting that these working capital management variables are consistent across CFO reports.Industry Rankings on Overall Working Capital Management Performance CFO magazine provides an overall working capital ranking for firms in its survey, using the following equation: Industry-based differences in overall working capital management are presented for the twenty-six industries that had at least eight companies included in the rankings each year. In the typical year, CFO magazine ranks 970 companies during this period. Industries are listed in order of the mean overall CFO ranking of working capital performance. Since the best average ranking possible for an eight-company industry is 4.5 (this assumes that the eight companies are ranked one through eight for the entire survey). It is quite obvious that all firms in the petroleum industry must have been receiving very high overall working capital management rankings. In fact, the petroleum industry is ranked first in CCE and third in DWC (as illustrated in Table 5 and discussed later in this paper). Furthermore, the petroleum industry had the lowest standard deviation of working capital rankings and range of working capital rankings. The only other industry with a mean overall ranking less than 100 was the Electric & Gas Utility industry, which ranked second in CCE and fourth in DWC. The two industries with the worst working capital rankings were Textiles and Apparel. Textiles rank twenty-second in CCE and twenty-sixth in DWC. The apparel industry ranks twenty-third and twenty-fourth in the two working capital measuresConclusions第5页（共6页）The research presented here is based on the annual ratings of working capital management published in CFO magazine. Our findings indicate a consistency in how industries “stack up” against each other over time with respect to the working capita l measures. However, the working capital measures themselves are not static (i.e. averages of working capital measures across all firms change annually); our results indicate significant movements across our entire sample over time. Our findings are important because they provide insight to working capital performance across time and on working capital management across industries. These changes may be in explained in part by macroeconomic factors. Changes in interest rates, rate of innovation and competition are likely to impact working capital management. As interest rates rise, there would be less desire to make payments early, which would stretch accounts payable, accounts receivable and cash accounts.The ramifications of this study include the finding of distinct levels of WCM measures for different industries, which tend to be stable over time. Many factors help to explain this discovery. The improving economy during the period of the study may have resulted in improved turnover in some industries, while slowing turnover may have been a signal of troubles ahead. Our results should be interpreted cautiously. Our study takes places over a short time frame during a generally improving market. In addition, the survey suffers from survivorship bias – only the top firms within each industry are ranked each year and the composition of those firms within the industry can change annually.Further research may take one of two lines. First, there could be a study of whether stock prices respond to CFO magazine’s publication of working cap ital management ratings. Second, there could be a study of which, if any, of the working capital management components relate to share price performance. Given our results, these studies need to take industry membership into consideration when estimating stock price reaction to working capital management performance.第6页（共6页）。

Another aspect of “optimal”is the extent to which poor financial results can be tied to sub-optimal pe rformance.Fortunately.these issues are testable with data published by CFO magazine. which claims to be the source of “tools and informati on for the financial executive.”and are the subject of this resear ch.In addition to providing mean and variance values for the working capital measures and the overall metric.two issues will be addressed in this research. One research question is. “are firms within a p articular industry clustered together at consistent levels of working capital measures?For instance.are firms in one industry able to quickl y transfer sales into cash.while firms from another industry tend to have high sales levels for the particular level of inventory . The other research question is. “does working capital management perform ance for firms within a given industry change from year-to-year?”The following section presents a brief literature review.Next.the r esearch method is described.including some information about the annual Working Capital Management Survey published by CFO magazine. Findings are then presented and conclusions are drawn.Related LiteratureThe importance of working capital management is not new to the f inance literature. Over twenty years ago. Largay and Stickney (1980) reported that the then-recent bankruptcy of W.T. Grant. a nationwide chain of department stores.should have been anticipated because the co rporation had been running a deficit cash flow from operations for e ight of the last ten years of its corporate life.As part of a stud y of the Fortune 500s financial management practices. Gilbert and Rei chert (1995) find that accounts receivable management models are used in 59 percent of these firms to improve working capital projects.wh ile inventory management models were used in 60 percent of the compa nies.More recently. Farragher. Kleiman and Sahu (1999) find that 55 p ercent of firms in the S&P Industrial index complete some form of a cash flow assessment. but did not present insights regarding account s receivable and inventory management. or the variations of any curre nt asset accounts or liability accounts across industries.Thus.mixed ev idence exists concerning the use of working capital management techniq ues.Theoretical determination of optimal trade credit limits are the s ubject of many articles over the years (e.g. Schwartz 1974; Scherr 1 996).with scant attention paid to actual accounts receivable management.Across a limited sample. Weinraub and Visscher (1998) observe a tend ency of firms with low levels of current ratios to also have low l evels of current liabilities. Simultaneously investigating accounts rece ivable and payable issues.Hill. Sartoris.and Ferguson (1984) find diffe rences in the way payment dates are defined. Payees define the date of payment as the date payment is received.while payors view paymen t as the postmark date.Additional WCM insight across firms.industries.a nd time can add to this body of research.Maness and Zietlow (2002. 51. 496) presents two models of value creation that incorporate effective short-term financial management acti vities.However.these models are generic models and do not consider uni que firm or industry influences. Maness and Zietlow discuss industry influences in a short paragraph that includes the observation that. “An industry a company is located in may have more influence on th at company’s fortunes than overall GNP”(2002. 507).In fact. a car eful review of this 627-page textbook finds only sporadic information on actual firm levels of WCM dimensions.virtually nothing on industr y factors except for some boxed items with titles such as. “Should a Retailer Offer an In-House Credit Card”(128) and nothing on WC M stability over time. This research will attempt to fill this void by investigating patterns related to working capital measures within industries and illustrate differences between industries across time.An extensive survey of library and Internet resources provided ver y few recent reports about working capital management. The most relev ant set of articles was Weisel and Bradley’s (2003) article on cash flow management and one of inventory control as a result of effect ive supply chain management by Hadley (2004).Research Method The CFO RankingsThe first annual CFO Working Capital Survey. a joint project with REL Consultancy Group.was published in the June 1997 issue of CFO (Mintz and Lezere 1997). REL is a London. England-based management co nsulting firm specializing in working capital issues for its global l ist of clients. The original survey reports several working capital b enchmarks for public companies using data for 1996. Each company is ranked against its peers and also against the entire field of 1.000 companies. REL continues to update the original information on an a nnual basis.REL uses the “cash flow from operations”value located on firm cash flow statements to estimate cash conversion efficiency (CCE). T his value indicates how well a company transforms revenues into cash flow. A “days of working capital”(DWC) value is based on the d ollar amount in each of the aggregate.equally-weighted receivables.inven tory.and payables accounts. The “days of working capital”(DNC) repr esents the time period between purchase of inventory on acccount fromvendor until the sale to the customer.the collection of the receiva bles. and payment receipt.Thus.it reflects the companys ability to fin ance its core operations with vendor credit. A detailed investigation of WCM is possible because CFO also provides firm and industry val ues for days sales outstanding (A/R).inventory turnover.and days payabl es outstanding (A/P).Research FindingsAverage and Annual Working Capital Management Performance Working capital management component definitions and average values for the entire 1996 –2000 period .Across the nearly 1.000 firms in the survey.cash flow from operations. defined as cash flow from operations divided by sales and referred to as “cash conversion ef ficiency”(CCE).averages 9.0 percent.Incorporating a 95 percent confide nce interval. CCE ranges from 5.6 percent to 12.4 percent. The days working capital (DWC). defined as the sum of receivables and invent ories less payables divided by daily sales.averages 51.8 days and is very similar to the days that sales are outstanding (50.6).because the inventory turnover rate (once every 32.0 days) is similar to the number of days that payables are outstanding (32.4 days).In all ins tances.the standard deviation is relatively small.suggesting that these working capital management variables are consistent across CFO report s.Industry Rankings on Overall Working Capital Management Perfo rmanceCFO magazine provides an overall working capital ranking for firms in its ing the following equation:Industry-based differences in overall working capital management are presented for the twenty-s ix industries that had at least eight companies included in the rank ings each year.In the typical year. CFO magazine ranks 970 companies during this period. Industries are listed in order of the mean ove rall CFO ranking of working capital performance. Since the best avera ge ranking possible for an eight-company industry is 4.5 (this assume s that the eight companies are ranked one through eight for the ent ire survey). it is quite obvious that all firms in the petroleum in dustry must have been receiving very high overall working capital man agement rankings.In fact.the petroleum industry is ranked first in CCE and third in DWC (as illustrated in Table 5 and discussed later i n this paper).Furthermore.the petroleum industry had the lowest standar d deviation of working capital rankings and range of working capital rankings. The only other industry with a mean overall ranking less than 100 was the Electric & Gas Utility industry.which ranked secon d in CCE and fourth in DWC. The two industries with the worst work ing capital rankings were Textiles and Apparel. Textiles rank twenty-s econd in CCE and twenty-sixth in DWC. The apparel industry ranks twenty-third and twenty-fourth in the two working capital measures ConclusionsThe research presented here is based on the annual ratings of wo rking capital management published in CFO magazine. Our findings indic ate a consistency in how industries “stack up”against each other over time with respect to the working capital measures.However.the wor king capital measures themselves are not static (i.e.. averages of wo rking capital measures across all firms change annually); our results indicate significant movements across our entire sample over time. O ur findings are important because they provide insight to working cap ital performance across time. and on working capital management across industries. These changes may be in explained in part by macroecono mic factors Changes in interest rates.rate of innovation.and competitio n are likely to impact working capital management. As interest rates rise.there would be less desire to make payments early.which would stretch accounts payable.accounts receivable.and cash accounts. The ra mifications of this study include the finding of distinct levels of WCM measures for different industries.which tend to be stable over ti me. Many factors help to explain this discovery. The improving econom y during the period of the study may have resulted in improved turn over in some industries.while slowing turnover may have been a signal of troubles ahead. Our results should be interpreted cautiously. Our study takes places over a short time frame during a generally impr oving market. In addition. the survey suffers from survivorship bias –only the top firms within each industry are ranked each year and the composition of those firms within the industry can change annua lly.Further research may take one of two lines.First.there could bea study of whether stock prices respond to CFO magazine’s publication of working capital management rating.Second,there could be a study of which if any of the working capital management components relate to share price performance.Given our results,there studies need to take industry membership into consideration when estimating stock price reaction to working capital management performance.对整个行业中营运资金管理的研究格雷格Filbeck.Schweser学习计划托马斯M克鲁格.威斯康星大学拉克罗斯摘要:企业能够降低融资成本或者尽量减少绑定在流动资产上的成立基金数额来用于扩大现有的资金。

营运资金管理国外文献综述摘要营运资金管理在企业财务管理中一直占据重要地位,营运资金管理水平的高低,直接影响业资金的流动性,进而影响成本与效益。

随着现代社会经济的高速发展,营运资金管理的重要性显得尤为突出。

本文首先对营运资金进行简要概述,在此基础上提出了我国企业营运资金管理中存在的问题并提出一些对策,以期对企业营运资金管理有积极的意义。

关键词营运资金流动资产管理一、营运资金概述营运资金又称为营运资本,有广义和狭义之分,广义的营运资金又称为毛营运资金是指一个企业的生产经营活动中流动资产占用的资金,具体包括现金、有价证券、应收账款、存货等占用的资金;狭义的营运资金又称为净营运资金,是指企业流动资产减去流动负债后的余额。

不论是广义还是狭义,营运资金从财务角度看应该是流动资产与流动负债关系的总和,在这里“总和”不是单纯数额的加总,而是关系的反映。

营运资金管理,是企业从管理获效益的重要手段。

为了有效地管理企业营运资金,必须研究企业营运资金的特点,以便有针对性地进行管理。

企业营运资金一般具有如下特点:第一,周转时间短。

根据这一特点,说明营运资金可以通过短期筹资方式加以解决。

第二,非现金形态的营运资金如存货、应收账款、短期有价证券等容易变现,这一点对企业应付临时性的资金需求有重要意义。

第三,数量具有波动性。

流动资产或流动负债容易受内外条件的影响,数量的波动往往很大。

第四,来源具有多样性。

营运资金的需求问题既可通过长期筹资方式解决,也可通过短期筹资方式解决。

二、我国企业营运资金管理存在的主要问题***一***融资困难,周转资金严重不足现在,我国一些企业初步建立了较为独立、渠道多元的融资体系。

地方各级***也为一些中小型企业提供财政支援;中国人民银行也鼓励各商业银行加大对中小企业的信贷支援。

这些措施改善了一部分企业融资难的困境。

但是,各金融机构在改进金融服务、开发适合中小企业发展的金融产品、调整信贷等方面还有缺陷。

中英文对照外文翻译文献(文档含英文原文和中文翻译)原文：Effects Of Working Capital Management On Sme ProfitabilityThe corporate finance literature has traditionally focused on the study of long-term financial decisions. Researchers have particularly offered studies analyzing investments, capital structure, dividends or company valuation, among other topics. But the investment that firms make in short-term assets, and the resources used with maturities of under one year, represent the main share of items on a firm’s balance sheet. In fact, in our sample the current assets of small and medium-sized Spanish firms represent 69.48 percent of their assets, and at the same time their current liabilities represent more than 52.82 percent of their liabilities.Working capital management is important because of its effects on the firm’s profitability and risk, and consequently its value (Smith, 1980). On the one hand, maintaining high inventory levels reduces the cost of possible interruptions in the production process, or of loss of business due to the scarcity of products, reducessupply costs, and protects against price fluctuations, among other advantages (Blinder and Manccini, 1991). On the other, granting trade credit favors the firm’s sales in various ways. Trade credit can act as an effective price cut (Brennan, Maksimovic and Zechner,1988; Petersen and Rajan, 1997), incentivizes customers to acquire merchandise at times of low demand (Emery, 1987), allows customers to check that the merchandise they receive is as agreed (quantity and quality) and to ensure that the services contracted are carried out (Smith, 1987), and helps firms to strengthen long-term relationships with their customers (Ng, Smith and Smith, 1999). However, firms that invest heavily in inventory and trade credit can suffer reduced profitability. Thus,the greater the investment in current assets, the lower the risk, but also the lower the profitability obtained.On the other hand, trade credit is a spontaneous source of financing that reduces the amount required to finance the sums tied up in the inventory and customer accounts. But we should bear in mind that financing from suppliers can have a very high implicit cost if early payment discounts are available. In fact the opportunity cost may exceed 20 percent, depending on the discount percentage and the discount period granted (Wilner,2000; Ng, Smith and Smith, 1999). In this respect, previous studies have analyzed the high cost of trade credit, and find that firms finance themselves with seller credit when they do not have other more economic sources of financing available (Petersen and Rajan, 1994 and 1997).Decisions about how much to invest in the customer and inventory accounts, and how much credit to accept from suppliers, are reflected in the firm’s cash conve rsion cycle, which represents the average number of days between the date when the firm must start paying its suppliers and the date when it begins to collect payments from its customers. Some previous studies have used this measure to analyze whether shortening the cash conversion cycle has positive or negative effects on the firm’s profitability.Specifically, Shin and Soenen (1998) analyze the relation between the cash conversion cycle and profitability for a sample of firms listed on the US stock exchange during the period 1974-1994. Their results show that reducing the cash conversion cycle to a reasonable extent increases firms’ profitability. More recently,Deloof (2003) analyzes a sample of large Belgian firms during the period 1992-1996. His results confirm that Belgian firms can improve their profitability by reducing the number of days accounts receivable are outstanding and reducing inventories. Moreover, he finds that less profitable firms wait longer to pay their bills.These previous studies have focused their analysis on larger firms. However, the management of current assets and liabilities is particularly important in the case of small and medium-sized companies. Most of these companies’ assets are in the form of current assets. Also, current liabilities are one of their main sources of external finance in view of their difficulties in obtaining funding in the long-term capital markets(Petersen and Rajan, 1997) and the financing constraints that they face (Whited, 1992; Fazzari and Petersen, 1993). In this respect, Elliehausen and Woken (1993), Petersen and Rajan (1997) and Danielson and Scott (2000) show that small and medium-sized US firms use vendor financing when they have run out of debt. Thus, efficient working capital management is particularly important for smaller companies (Peel and Wilson,1996).In this context, the objective of the current work is to provide empirical evidence about the effects of working capital management on profitability for a panel made up of 8,872 SMEs during the period 1996-2002. This work contributes to the literature in two ways. First, no previous such evidence exists for the case of SMEs. We use a sample of Spanish SMEs that operate within the so-called continental model, which is characterized by its less developed capital markets (La Porta, López-de-Silanes, Shleifer, and Vishny, 1997), and by the fact that most resources are channeled through financial intermediaries (Pampillón, 2000). All this suggests that Spanish SMEs have fewer alternative sources of external finance available, which makes them more dependent on short-term finance in general, and on trade credit in particular. As Demirguc-Kunt and Maksimovic (2002) suggest, firms operating in countries with more developed banking systems grant more trade credit to their customers, and at the same time they receive more finance from their own suppliers. The second contribution is that, unlike the previous studies by Shin and Soenen (1998) and Deloof (2003), in the current work we have conducted tests robust to the possible presence ofendogeneity problems. The aim is to ensure that the relationships found in the analysis carried out are due to the effects of the cash conversion cycle on corporate profitability and not vice versa.Our findings suggest that managers can create value by reducing their firm’s number of days accounts receivable and inventories. Similarly, shortening the cash conversion cycle also improves the firm’s profitability.We obtained the data used in this study from the AMADEUS database. This database was developed by Bureau van Dijk, and contains financial and economic data on European companies.The sample comprises small and medium-sized firms from Spain. The selection of SMEs was carried out according to the requirements established by the European Commission’s recommendation 96/280/CE of 3 April, 1996, on the definition of small and medium-sized firms. Specifically, we selected those firms meeting the following criteria for at least three years: a) have fewer than 250 employees; b) turn over less than €40 million; and c) possess less than €27 million of total assets.In addition to the application of those selection criteria, we applied a series of filters. Thus, we eliminated the observations of firms with anomalies in their accounts, such as negative values in their assets, current assets, fixed assets, liabilities, current liabilities, capital, depreciation, or interest paid. We removed observations of entry items from the balance sheet and profit and loss account exhibiting signs that were contrary to reasonable expectations. Finally, we eliminated 1 percent of the extreme values presented by several variables. As a result of applying these filters, we ended up with a sample of 38,464 observations.In order to introduce the effect of the economic cycle on the levels invested in working capital, we obtained information about the annual GDP growth in Spain from Eurostat.In order to analyze the effects of working capital management on the firm’s profitability, we used the return on assets (ROA) as the dependent variable. We defined this variable as the ratio of earnings before interest and tax to assets.With regards to the independent variables, we measured working capitalmanagement by using the number of days accounts receivable, number of days of inventory and number of days accounts payable. In this respect, number of days accounts receivable (AR) is calculated as 365 ×[accounts receivable/sales]. This variable represents the average number of days that the firm takes to collect payments from its customers. The higher the value, the higher its investment in accounts receivable.We calculated the number of days of inventory (INV) as 365 ×[inventories/purchases]. This variable reflects the average number of days of stock held by the firm. Longer storage times represent a greater investment in inventory for a particular level of operations.The number of days accounts payable (AP) reflects the average time it takes firms to pay their suppliers. We calculated this as 365 × [accounts payable/purchases]. The higher the value, the longer firms take to settle their payment commitments to their suppliers.Considering these three periods jointly, we estimated the cash conversion cycle(CCC). This variable is calculated as the number of days accounts receivable plus thenumber of days of inventory minus the number of days accounts payable. The longerthe cash conversion cycle, the greater the net investment in current assets, and hence the greater the need for financing of current assets.Together with these variables, we introduced as control variables the size of the firm, the growth in its sales, and its leverage. We measured the size (SIZE) as the logarithm of assets, the sales growth (SGROW) as (Sales1 –Sales0)/Sales0, the leverage(DEBT) as the ratio of debt to liabilities. Dellof (2003) in his study of large Belgian firms also considered the ratio of fixed financial assets to total assets as a control variable. For some firms in his study such assets are a significant part of total assets.However our study focuses on SMEs whose fixed financial assets are less important. In fact, companies in our sample invest little in fixed financial assets (a mean of 3.92 percent, but a median of 0.05 percent). Nevertheless, the results remain unaltered whenwe include this variable.Furthermore, and since good economic conditions tend to be reflected in a firm’sprofitability, we controlled for the evolution of the economic cycle using the variable GDPGR, which measures the annual GDP growth.Current assets and liabilities have a series of distinct characteristics according to the sector of activity in which the firm operates. Thus, Table I reports the return on assets and number of days accounts receivable, days of inventory, and days accounts payable by sector of activity. The mining industry and services sector are the two sectors with the highest return on their assets, with a value of 10 percent. Firms that are dedicated to agriculture, trade (wholesale or retail), transport and public services, are some way behind at 7 percent.With regard to the average periods by sector, we find, as we would expect, that the firms dedicated to the retail trade, with an average period of 38 days, take least time to collect payments from their customers. Construction sector firms grant their customers the longest period in which to pay –more than 145 days. Next, we find mining sector firms, with a number of days accounts receivable of 116 days. We also find that inventory is stored longest in agriculture, while stocks are stored least in the transport and public services sector. In relation to the number of days accounts payable, retailers (56 days) followed by wholesalers (77 days) pay their suppliers earliest. Firms are much slower in the construction and mining sectors, taking more than 140 days on average to pay their suppliers. However, as we have mentioned, these firms also grant their own customers the most time to pay them. Considering all the average periods together, we note that the cash conversion cycle is negative in only one sector – that of transport and public services. This is explained by the short storage times habitual in this sector. In this respect, agricultural and manufacturing firms take the longest time to generate cash (95 and 96 days, respectively), and hence need the most resources to finance their operational funding requirements.Table II offers descriptive statistics about the variables used for the sample as a whole. These are generally small firms, with mean assets of more than €6 milli on; their return on assets is around 8 percent; their number of days accounts receivable is around 96 days; and their number of days accounts payable is very similar: around 97 days. Together with this, the sample firms have seen their sales grow by almost 13percent annually on average, and 24.74 percent of their liabilities is taken up by debt. In the period analyzed (1996-2002) the GDP has grown at an average rate of 3.66 percent in Spain.Source: Pedro Juan García-Teruel and Pedro Martínez-Solano ,2006.“Effects of Working Capital Management on SME Profitability” .International Journal of Managerial Finance ,vol. 3, issue 2, April,pages 164-167.译文：营运资金管理对中小企业的盈利能力的影响公司理财著作历来把注意力集中在了长期财务决策研究，研究者详细的提供了投资决策分析、资本结构、股利分配或公司估值等主题的研究，但是企业投资形成的短期资产和以一年内到期方式使用的资源，表现为公司资产负债表的有关下昂目的主要部分。

外文翻译The focus of working capital managementin UK small firms（节选）Author：Carole Howorth，Paul WestheadNationality：Nottingham NG8 1BB, UKDerivation: Management Accounting Research NO.14,2003, PP.94–111 AbstractWorking capital management routines of a large random sample of small companies in the UK are examined. Considerable variability in the take-up of 11 working capital management routines was detected. Principal components analysis and cluster analysis confirm the identification of four di stinct ‘types’ of companies with regard to patterns of working capital management. The first three ‘types’ of companies focused upon cash management, stock or debtors routines respectively, whilst the fourth ‘type’ were less likely to take-up any working capital management routines. Influences on the amount and focus of working capital management are discussed. Multinomial logistic regression analysis suggests that the selected independent variables successfully discriminated between the four ‘types’ of companies. The results suggest that small companies focus only on areas of working capital management where they expect to improve marginal returns. The difficulties of establishing causality are highlighted and implications for academics, policy-makers and practitioners are reported.Conclusions and implicationsThe aim of this study has been to encourage additional research, rather than to provide an exhaustive review of all the factors associated with the take-up of working capital management routines by small companies. Three theories guided the selection of the independent variables explored in this study. The RBV highlighted that small firms have idiosyncratic bundles of resources associated with the take-up of working capital management routines. Agency theory identified the influence of external stakeholders as well as differences between small and large firms. Transactions costs theory indicated that small firms might invest resources in specific areas of working capital management if they perceive them to offer the highest marginal return.The results consistently highlighted, across a variety of statistical tests, that small firms are not a homogenous group with regard to working capital management routines. Considerable variability was detected in the take-up of 11 working capital management routines by a large random sample of small companies in the UK. Evidence from the PCA and the cluster analysis confirmed the identification of four distinct ‘types’ of companies with regardto the take-up of working capital management routines. Moreover, evidence from the multinomial logistic regression analysis suggests that the selected independent variables successfully discriminated between the four ‘types’ of companies. Twelve out of the 18 hypotheses were supported. A further two hypotheses showed the anticipated relationship but were not significant discriminators between the ‘types’ of companies.Evidence that the majority of small companies focus their efforts on one area of working capital management indicates that resources for working capital management are limited. However, a striking finding from the regression analysis was the detection that firms which utilize fewer working capital management routines were not necessarily smaller companies. We can infer here that resource constraints per se may not be the major barrier to the utilization of working capital management routines by smaller companies. Instead, the results provide an indication that the perceived marginal return on committing resources may be a major influence on the extent and focus of working capital management.However, we acknowledge that a cross-sectional study such as this one cannot establish causality and can only provide an indication of associations that warrant further investigation. Additional studies could usefully explore the stimuli leading to the utilisation of working capital management routines and the barriers to their take-up. The dynamics of working capital management are complex and the links with performance are bidirectional and difficult to unravel. Small companies may invest resources into managing a particular area of working capital where they are performing badly because the returns from controlling the problem area are perceived to be high. If the direction of causality is not understood, an overly simplistic conclusion in this instance could be that investment of more resources into an area leads to worse performance. The complexity of causality makes it difficult to establish the effect of working capital management routines on the performance of the firm. We can infer that firms with a lower propensity to undertake working capital management routines are not significantly associated with increased cash flow problems, nor reduced profitability. There is some indication that these may be ‘lifestyle’ firms but additional research is required before firm conclusions can be drawn. Currently, it is not clear whether these laggard working capital firms are underperforming or have untapped potential for growth.In a similar way, the direction of causality is not clear with regard to the link between the take-up of working capital management routines and the level of financial skills in a firm. This study employed a simple proxy measure of financial sophistication. Further research is warranted to investigate the direction and the strength of the links between the take-up of working capital management routines and financial management skills and training, education and prior experience. Additional multivariate statistical studies are also required in a variety of national, cultural and industrial contexts toidentify the combination of internal and external environmental factors associated with the take-up of working capital management routines by different employment size bands of private firms (i.e. micro, small, medium and large).Qualitative studies and longitudinal research will provide fresh insights into the processes and dynamics of working capital management, as well as the complex strands of causality (Scapens, 1990).Policy-makers and practitioners seeking to increase the stock of professionally managed firms, might need to target their assistance towards owners of small firms who face attitudinal, resource and operational barriers to the utilization of working capital management routines. Presented evidence suggests that small companies should not be viewed as a homo generous entity with regard to their working capital management routines.Policy-makers and practitioners need to appreciate this diversity and they may use the presented evidence to tailor assistance to the needs of particular ‘types’ of companies, rather than providing ‘blanket” support to all firms irrespective of aspirations or resources.Policy-makers and practitioners need to appreciate the management time constraint faced by many small firms. Time constraints not only limit the amount of time for working capital management , but also the amount of time available to assess whether changes to current working capital management policy would be worthwhile. Moreover, we might expect improved skills to lead to more efficient use of time but small firm managers will require powerful evidence to convince them of the benefits of investing time in financial skills training. The take-up of routines (and financial skills training) could be increased if it was conclusively confirmed that firms significantly improve their performance after introducing appropriate working capital management routines. Additional longitudinal, qualitative and multivariate statistical evidence is warranted that explores whether the take-up of working capital management routines by small firms is subsequently associated with superior levels of performance. Best business practice evidence, from case studies, could also be utilised by policy-makers and practitioners to convince more owners of small firms of how specific working capital management routines can be used proactively to address constraints on business development.
