And in many enterprises, network technology can be said also been considerable development, and is widely applied to the company's management to go. In this paper, the role of technology in business management network play to start, analyzes the network technology in the enterprise management application and development.

Keywords: network technology; development enterprise; management

applications

Today's society can be said to be a social network , but also a social message. Modern companies want to seek development , it had to rely on the network , depending on the transmission and exchange of information between large networks . Therefore, in the management of enterprises , the full use of network technology , increase mutual exchanges between enterprises and the information transfer , and use some of the network management tools to achieve enterprise management modernization , efficient, simple, and scientific the key is to adapt to the market economy enterprises to improve their market competitiveness, reduce management costs increase economic efficiency , strengthening internal management to achieve an important way . So, for enterprises, the full application of network technology, information sharing within the enterprise and between enterprises , - 2 -

complement each other , is the only way companies implement sustainable and healthy development.

1 The role of a network technology in the enterprise management An integrated computer network technology and communication technology and the development of information technology, information technology . With the popularity of the Internet , has been widely applied to business management. It is an important role to play in business management in the performance of the following main aspects .

1.1 simplify enterprise management procedures to facilitate management and coordination of various departments

The use of network technology to simplify the company's management procedures , and to some extent, promoted the coordination of various departments enterprise management. Specifically, as a business, through the use of network technology , and information collection, collation, transmission, processing , fast communication and economy , and because of computer-assisted management program can achieve a lot in the network, which in simplifying the management process a certain extent . And through the local area network applications, and increasing the exchange of information , internal management model has gradually achieve a level of management style , top managers to get rid of some of the management chores , thus contributing to the coordination between the various departments of administration improve management efficiency.

1.2 Integration of business and financial information , to strengthen monitoring efforts

In the network conditions, due to network technology widely used in the enterprise , financial information and business information within the enterprise through the network has been highly integrated , and enterprise network through a clear reaction , for internal information, logistics and funding so can be a good grasp , which greatly enhance the management - 3 -

efficiency . As well as in the management of enterprises , because of network technology with remote processing and other functions, so in the management process will strengthen efforts to monitor , through the network of the clarity of the records of various departments within the enterprise management down, raise the transparency of corporate management.

1.3 Close business and social connections , optimizing the allocation of resources Universal application of network technology close ties between business and society . In the network can be set up business enterprises exclusive network window to achieve contact with customers , suppliers, distributors and other external resources , and also through online billing and other technologies to strengthen ties with financial institutions, government departments. And through the network of interactive technology , companies can realize the link between the various departments , subsidiaries, to provide customers with satisfactory service to win the market . Of course, in addition to close ties between the community , the application of network technology also allows businesses to optimize the allocation of internal resources , the flow of resources across the enterprise , improve the efficiency of resource utilization , thereby enhancing their market competitiveness.
