JCR期刊影响因子及分区情况 中科院SCI期刊分区表 工程技术类

中科院、JCR和SCI分区都是用于评价学术期刊影响力和质量的分区方式，但它们在学科分区、评价指标和阈值选取等方面存在差异。

1. 学科分区：中科院分区、JCR分区和SCI分区都是按照学科分类标准将学术期刊分为不同的学科分区。

其中，中科院分区和SCI分区是按照《科学引文索引》（SCI）的学科分类标准进行划分，而JCR分区则是按照《科学引文报告》（JCR）的学科分类标准进行划分。

具体来说，JCR分区按照小类的专业划分，共有176个，而中科院SCI分区基于JCR分区，将176个小类专业合并为了医学、生物学等14个学科。

2. 评价指标：SCI和JCR分区均以影响因子（Impact Factor）为主要评价指标。

影响因子是指某期刊在特定年份中的被引用次数除以该期刊在特定年份中的论文发表数量。

中科院分区则综合考虑了影响因子、总被引频次、论文篇数、篇均被引频次等多项指标。

3. 阈值选取：对于期刊的分区阈值选取，JCR是按等比例划分的，而中科院SCI则是通过指定阈值进行划分。

具体来说，中科院SCI分区的一区、二区和三区的影响因子均高于JCR分区，因此相对来说，中科院分区的一区含金量会更高一些。

综上所述，中科院、JCR和SCI分区的学科分类、评价指标和阈值选取等方面存在差异，但它们都是评价学术期刊影响力和质量的重要工具。

选择哪种分区方式主要取决于评价需求和目的。

中国科学院最新发布了2024年最新SCI影响因子及分区，该报告以
中国科学院JCR版为基础，综合反映SCI期刊在该分区的整体影响力的水平。

2024年JCR版SCI影响因子具体分布如下：
Q1分区：Q1分区共有817本期刊入选；其中，（1）中科院一区期刊288本；（2）中科院二区期刊483本；（3）中科院三区期刊46本。

Q2分区：有1389本期刊入选；其中，（1）中科院一区期刊137本；（2）中科院二区期刊968本；（3）中科院三区期刊284本。

Q3分区：共有3188本期刊入选；其中，（1）中科院一区期刊41本；（2）中科院二区期刊2120本；（3）中科院三区期刊1027本。

Q4分区：有4196本期刊入选；其中，（1）中科院一区期刊9本；（2）中科院二区期刊2783本；（3）中科院三区期刊1404本。

2024年各分区SCI影响因子的影响力分别排名如下：
Q1分区：自然出版集团的《自然-通讯》以13.042的影响因子居首；施普林格出版集团的《细胞》以12.124的影响因子排名第二；美国化学
学会《美国化学会杂志》以11.841的影响因子排名第三。

中科院分区影响因子是根据期刊的学术质量和影响力进行分区的，旨在评估期刊的学术水平。

根据最新的中科院分区表，各个学科领域的期刊被分为1-4区，其中1区期刊的学术质量和影响力最高，4区期刊的学术质量和影响力最低。

需要注意的是，中科院分区影响因子的评估标准是相对的，不同学科领域的期刊之间的比较和评估具有一定的主观性。

因此，在评估期刊的学术水平时，需要综合考虑多方面的因素，包括但不限于影响因子、论文质量、学术声誉等。

如果需要具体的中科院分区影响因子数据，建议查阅中科院科技论文发布平台等相关网站，这些网站会提供详细的分区影响因子数据和说明。

同时，也可以参考最新的学术出版物和研究成果，了解各个学科领域的期刊最新动态和趋势。

SCI分区是针对期刊进行的一种分类方法，主要分为JCR分区和中科院分区两种。

JCR分区是按照影响因子(IF值)进行划分，将某一个学科的所有期刊都按照上一年的影响因子降序排列，然后平均分为四个区，分别是Q1、Q2、Q3、Q4，每个区都对应一区、二区、三区和四区。

中科院分区则是将所有期刊三年平均影响因子的前5%归为1区，6%-20%为2区，21%-50%为3区，后51%-100%为4区。

与JCR分区不同的是，中科院分区不按照当年影响因子划分，而是参考了期刊三年的平均影响因子。

另外，在学科分类方面，JCR分区是按照小类划分，而中科院分区是大类划分，例如医学、生物、农林科学、环境科学与生态学、化学、工程技术、数学、物理、地学、地学天文、社会科学、管理科学及综合性期刊等。

此外，分区阈值也不同。

JCR分区是按每区25%的等比例进行划分，而中科院分区的一区、二区和三区的阈值均高于JCR分区的一二三区。

总的来说，SCI分区是一种针对期刊的分类方法，旨在方便地识别期刊的水平和地位。

不同的分区方法和学科分类标准可能会导致同一期刊在不同分区中的位置不同。

因此，在选择期刊时，需要根据具体情况进行综合考虑和分析。

中科院大类分区及影响因子
中科院首先将JCR中所有期刊分为数学、物理、化学、生物、地学、天文、工程技术、医学、环境科学、农林科学、社会科学、管理科学及综合性期刊13大类。

然后，将13大类期刊分各自为4个等级，即4个区。

按照各类期刊影响因子划分，前5%为该类1区、6%～20%为2区、21%～50%为3区，其余的为4区。

具体来说，工程技术类期刊中，有3本国产期刊位列综合性期刊1区，Nature Energy近三年平均影响因子53.784，在工程技术类非综述类期刊排名第一。

Joule入选工程技术类第四名（去年第六），仅次于Nature Reviews Materials，Nature Energy和NATURE MATERIALS，高于Nature Nanotechnology。

中科院sci分区大类和小类中科院SCI分区大类和小类是指中国科学院SCI分区数据库中对文献进行分类的体系。

该体系根据不同学科领域的特点进行细分，旨在更好地管理和组织科研文献资源。

下面我们将介绍中科院SCI分区大类和小类的情况。

中科院SCI分区大类主要包括四个领域，分别是自然科学、工程技术、生命科学和医学、社会科学。

自然科学领域包括物理学、化学、天文学、地球科学等学科；工程技术领域包括计算机科学、电子通信、建筑土木等学科；生命科学和医学领域包括生物学、生态学、药学、医学等学科；社会科学领域包括经济学、管理学、心理学、教育学等学科。

在大类下面，中科院SCI分区进一步细分为小类，以更加精确地分类和组织文献。

例如，在自然科学领域中，物理学下的小类有天体物理学、固体物理学、原子分子物理学等；化学领域下的小类有有机化学、无机化学、分析化学等；生物学领域下的小类有动物学、植物学、微生物学等。

中科院SCI分区大类和小类的设立，使得研究者能够更有针对性地搜索和浏览相关领域的文献，提高研究效率。

此外，这一体系也有助于科技管理部门了解科研成果的分布和发展趋势，为科研政策制定提供参考依据。

需要指出的是，中科院SCI分区大类和小类是根据中国科学院自建的分区数据库而来，并不完全对应于国际SCI数据库的分类体系。

因此，在进行文献检索时，除了参考中科院分区外，还应注意国际SCI 数据库中的相关分类。

总之，中科院SCI分区大类和小类是中国科学院对科研文献进行分类和组织的重要体系。

通过这一分类体系，研究者可以更加方便地检索和浏览相关学科领域的文献资源，提高科研效率。

同时，这一分类体系也为科研管理提供了重要的参考依据，能够帮助科技管理部门了解科研成果的分布和发展趋势，从而更好地制定科研政策。

中科院SCI分区大类和小类是中国科学院SCI分区数据库中对文献进行分类的一套体系，主要用于科技管理和科研文献资源管理。

根据学科领域的特点，中科院SCI将文献分为自然科学、工程技术、生命科学和医学、社会科学四大类。

请注意，这些数据只是其中一部分期刊在2024年的影响因子和分区
情况，而且这些数据也可能会随时间变化而有所调整。

SCI期刊的影响因
子和分区是根据文章的引用次数、发表的文章数量以及其他相关指标来计
算和评估的，因此在科研界中被广泛用作期刊的质量评价指标。

中科院SCI综合性期刊影响因子（Impact Factor，IF）是衡量期刊学术影响力的重要指标之一、影响因子通过统计前两年的引用数据，反映了该期刊的引用频次和引用质量，以衡量该期刊在学术界的影响力。

以下是2024年中科院SCI综合性期刊影响因子的一些相关信息：
1. 《自然》（Nature）
2024年影响因子：43.070
《自然》是世界上最具影响力的科学综合性期刊之一，发表了众多具有重大科学突破的原创研究成果。

2. 《科学》（Science）
2024年影响因子：41.063
《科学》是美国科学界最著名的综合性学术期刊之一，以发表重要科学成果闻名于世。

3. 《细胞》（Cell）
2024年影响因子：36.216
《细胞》是细胞生物学领域的顶级期刊，发表了大量具有重要科学意义的细胞生物学研究成果。

4. 《柳叶刀》（The Lancet）
2024年影响因子：59.102
《柳叶刀》是英国最负盛名的医学期刊之一，涵盖了各个医学领域的研究成果。

5.《美国国家科学院院刊》（PNAS）
2024年影响因子：9.580
作为美国国家科学院的官方期刊，PNAS发表了各个科学领域的重要
研究成果，是跨学科研究的主要出版平台之一
值得注意的是，影响因子只是衡量期刊学术影响力的一个指标，无法
全面反映期刊的质量和学术水平。

因此，在选择期刊投稿时，除了关注影
响因子，还应该考虑期刊的学科覆盖范围、审稿速度、国际知名度等因素，以使投稿研究成果得到更广泛的学术认可。

SCI分区，看JCR还是中科院？到底哪个更靠谱？本⽂来源：⽣科院⼥学霸⼀说到SCI分区这个话题，学霸姐姐就想起了“热门⽹红”期刊——Nature Communication，它平均影响因⼦10分以上、2年内总被引达302306次、各种话题不断、Nature亲⼉⼦.......然⽽，它却被划中科院划到了2区。

到底分区的⾼低是不是判断⼀刊杂志好坏的⼀种标准呢?我们发SCI论⽂到底以哪个分区为准呢?今天，学霸姐姐就带⼤家详细了解⼀下。

什么是期刊分区？关于JCR(Journal Citation Reports, 期刊引证报告) 期刊分区影响较为⼴泛的有两种：⼀种是科睿唯安公司制定的分区(原来是汤森路透，后来易主科睿唯安)；第⼆种是中国科学院国家科学图书馆制定的分区(简称中科院分区)。

这两种分区⽅式均基于 SCI 收录期刊影响因⼦基础之上进⾏分区的。

SCI 是什么的简称？这个问题，⼀定要说⼀下，因为学霸姐姐知道，很多⼈以为SCI是science的简称。

其实并不是，SCI全称是Science Citation Index(科学引⽂索引)。

是1961年由美国科学信息研究所创办的引⽂数据库，是国际公认的进⾏科学统计与评价的主要检索⼯具。

20世纪80年代末南京⼤学最先将SCI 引⼊我国的科研评价体系。

SCI为什么要分区？期刊的IF每年不断浮动，把IF定值作为学术评价指标不适合，⽽且不同学科领域期刊的影响因⼦差异很⼤，仅凭IF不能直观地⽐较不同领域的期刊。

于是，把同⼀学科领域的期刊，按IF⼤到⼩做排序后，划分⼊不同区域。

那么，只要是某领域1区的期刊，就是该领域的顶级刊物，直观反映该刊在领域内的⽔准和⼤致排位。

科睿唯安JCR分区科睿唯安每年出版JCR（《期刊引⽤报告》，全称Journal Citation Reports）。

JCR将收录期刊分为176个不同学科类别，每个学科分类按照期刊的影响因⼦⾼低，平均分为4个区：影响因⼦前25%（含25%）的期刊为Q1区；影响因⼦位于25-50%（含50%）为Q2区；影响因⼦位于50-75%（含75%）为Q3区；影响因⼦位于75%之后的期刊为Q4区。

中科院认定的sci分区表
中科院并不直接发布SCI分区表，而是由其下属的中国科学技
术信息研究所（简称中科信息所）负责发布。

SCI分区表是根据期
刊在科学引文索引（Science Citation Index，简称SCI）数据库
中的影响因子和被引频次等数据进行评定的。

SCI分区包括了不同
领域的期刊，每个期刊都会被分配到相应的分区，如Q1、Q2、Q3和
Q4。

Q1表示影响因子排名在该领域前25%，Q2表示排名在25%-50%，Q3表示排名在50%-75%，Q4表示排名在75%-100%。

中国科学技术信息研究所每年都会发布最新的SCI分区表，研
究人员可以通过该表了解期刊的影响力和被引频次情况，以便选择
合适的期刊投稿或者进行科研评估。

SCI分区表的发布对于科研人员、科研机构和科研项目的评估都具有重要意义。

总的来说，SCI分区表对于科研工作者来说是一个重要的参考
工具，有助于他们选择合适的期刊发表论文，评价期刊的学术水平，提升自身的学术声誉。

希望这些信息能够对你有所帮助。

解析中科院sci分区和JCR分区
中科院sci分区和JCR分区区别为：依据不同、划分不同、归类不同
一、依据不同
1、sci分区：sci分区是按期刊的前三年平均影响因子来划分的。

2、JCR分区：JCR分区是把某一个学科的所有期刊的上一年的影响因子按降序排列，然后进行等分分区。

二、划分不同
1、sci分区：sci分区分为四个区度，每个区所占的比例是不相等的，一区：前5%；
二区：6%~20%；
三区：21%~50%；
四区：51%~100%。

2、JCR分区：JCR分区分为四个区度，每个区所占的比例是相等的，一区：前25%(含25%)
二区：前25 -50% (含50%)
三区：前50-75% (含75% )
四区：前75%~100%
三、归类不同
1、sci分区：sci分区基于JCR分区，将176个小类专业合并为了医学、生物学等14个学科。

2、JCR分区：JCR分区按照小类的专业将学科归类174个小类。

总结：虽然是两个概念，但还是有一定联系，中科院的分区参考了JCR 的分区标准，但是中科院的分区比JCR的分区更严格一些。
