摘 要:对2011年SCI-E收录的8 281种期刊的主要文献计量学指标与特征因子之间的相关性进行了研究,通过Spearman秩相关分析,发现特征因子与总被引频次、5IF-被引量、IF-被引量具有高度的正相关关系,与影响因子、5年影响因子、自引量、当年文献量、即年指标、IF-自引量以及出版周期之间也具有一定的正相关关系,与期刊的综述篇均引文数、论著篇均引文数、被引半衰期之间具有低正相关关系,与期刊IF-自引率、引用半衰期和自引率具有低负相关关系;通过进一步的变量转换统计学分析和多元线性回归,得出特征因子的95%正常值范围为(0.000 181,+∞;n=8 168),特征因子和5IF-被引量以及2年总自引率之间具有一定的关系,期刊的5IF-被引量较小时得出的特征因子值将很小,因此,对于国内大多数年被引频次较低的期刊群来说,特征因子的评价灵敏度较低。This paper studies the correlation between the main bibliometric indicators and eigenfactors of 8 281 journals collected by SCI-E in 2011, and through Spearman rank correlation analysis, finds that the eigenfactor of journal has highly positive correlation with total citation frequency, 5-IF cited number and IF cited number, has a certain positive correlation with impact factor, 5 year's impact factor, self-citation number, current year's literature amount, current-year index, IF self-citation number and publication frequency, has low positive correlation with average number of citations of journals' review papers,average number of citations of journals' academic papers and cited half life,and has low negative correlation with journals' IF self-citation rate, cited half life of citation and self-citation rate; and through the further variable transformation statistical analysis and multivariate linear regression, obtained that 95% normal values range of eigenfactor is(0.000 181,+∞;n=8 168), and the eigenfactor has a certain correlation with 5-IF cited number and 2-year self-citation rate, and the value of the eigenfactor will be very small when 5-IF cited number is smaller, so, for the most domestic journals with lower citation frequency per year, the evaluation sensitivity of the eigenfactor is lower.
