数字资源获取对科学研究的影响——电子期刊全文下载与引用分析

Understanding the Influence of Digital Resources on Scientific Research

根据中国科学院国家科学图书馆构建的数字资源环境,以化学领域的15种电子期刊为统计分析样本,分析2003-2005年的全文下载量。利用中国科学引文数据库中国科学院著者引用这15种期刊的引用数据,分析下载行为与引用行为相关的关系。通过数据的统计分析,可以看出数字资源对科学研究行为的影响:期刊全文的高下载量为持续状态;期刊下载行为与期刊引用行为的趋势基本一致;高下载量的期刊引用次数也比较高;下载量低的期刊引用量也比较低。以期刊下载量为自变量,期刊的引用量为因变量,进行线性相关分析。利用皮尔松Person相关系数公式计算证明了下载行为与引用行为存在正向相关关系。

Digital library development caused great change on the way of information access. Based on the case of the Library of Chinese Academy of Sciences, this paper took 15 tides of e-journal with higher full text download capacity in chemistry domain as the statistical samples to analyze the full text download capacity during 2003 - 2005. It was counted how the authors of Chinese Academy of Science quoted the 15 tides by LCAS of Chinese Science Citation Database （CSCD） and the TSI-SCI database. It also analyzed the relationship between downloading behavior and the citation behavior.
