中文摘要:
      【目的】 以《期刊引证报告》(JCR)内的6门学科为基础,分析期刊影响因子相关自被引率(SCR-IF),为深入解析自被引率(SCR)在期刊评价中的作用提供数据参考。【方法】 分别在SCI和SSCI中各选择相互独立的3门学科,充分考虑学科规模和影响力大小的差异性,计算各期刊的SCR、SCR-IF,以及非影响因子相关自被引率(SCR-NIF),对比分析不同JCR学科以及不同期刊分区中SCR-IF的分布特征。同时,对SCR-IF与期刊其他主要文献计量学指标进行Pearson相关性分析。【结果】 列入研究的401种期刊中,SCR-IF大于0的期刊占93.77%;6门学科内,SCR-IF的平均值大于SCR的平均值,SCR的平均值大于SCR-NIF的平均值;Q1区和Q2区期刊的SCR-IF均小于Q3区和Q4区期刊的SCR-IF;SCR-IF与期刊其他主要文献计量学指标具有相关性,但是相关系数较小。【结论】 各学科期刊的SCR-IF均大于SCR和SCR-NIF;SCR-IF在影响力较高的期刊中相对较小。
英文摘要:
      [Purposes] Based on six disciplines of <i>Journal Citation Reports</i>, this paper aims to analyze the effect of self-cited rate correlated with impact factor(SCR-IF)and provide statistical reference for further analysis of self-cited rate(SCR)in journal evaluation. [Methods] Three independent disciplines were respectively selected from both <i>Science Citation Index</i> and <i>Social Science Citation Index</i> with the consideration of differences in scale and influence of the disciplines. SCR, SCR-IF and self-cited rate non-correlated with impact factor(SCR-NIF)in journals were calculated. Pearson correlation analysis was conducted to analyze the correlation between SCR, SCR-IF, SCR-NIF and the commonly used bibliometric indicators. [Findings] Among 401 journals included in this research, journals whose SCR-IF is larger than 0 account for 93. 77%. In six disciplines, the average SCR-IF is larger than the average SCR, and the average SCR is also larger than the average SCR-NIF. The SCR-IF in Q1 quartile and Q2 quartile are lower than those in Q3 quartile and Q4 quartile. The correlations between SCR-IF and main bibliometric indexes are weak. [Conclusions] The SCR-IF is larger than both SCR and SCR-NIF in six disciplines, and the SCR-IF is relatively small in journals with high impact factors.
