我国数学期刊的引文影响与引文环境

The Citation Impacts and Citation Environments of Chinese Journals in Mathematics

Ping Zhou, Loet Leydesdorff

摘要:

基于中国科技论文与引文数据库(CSTPCD)收录的期刊引文数据,应用专门开发的程序,获得了期刊间引文环境的聚合。期刊的本地引文影响力定义为期刊在本地引文环境中所占总引文量的份额,以比率的形式表示,可以通过节点的大小来可视化。节点的垂直大小与期刊的总引用份额成比例变化,而节点的水平大小用于提供期刊内(自)引用校正后的引用信息。本研究分析了三种中国数学期刊的引文影响力,并比较了本地引文影响力和影响因子。地方引文影响比(全球)影响因子更能反映期刊的地位和功能。我们还发现,中国期刊的作者更喜欢国际而不是国内的来源作为他们的引文。

英文摘要:

Based on the citation data of journals covered by the China Scientific and Technical Papers and Citations Database (CSTPCD), we obtained aggregated journal-journal citation environments by applying routines developed specifically for this purpose. Local citation impact of journals is defined as the share of the total citations in a local citation environment, which is expressed as a ratio and can be visualized by the size of the nodes. The vertical size of the nodes varies proportionally to a journal's total citation share, while the horizontal size of the nodes is used to provide citation information after correction for the within-journal (self-) citations. In this study, we analyze citation impacts of three Chinese journals in mathematics and compare local citation impacts with impact factors. Local citation impacts reflect a journal's status and function better than (global) impact factors. We also found that authors in Chinese journals prefer international instead of domestic ones as sources for their citations.
