[Purpose/Significance]The study on self-citation of journals plays an important role in analyzing the re?search interests of journals and evaluating the quality of journals.[Method/Process]In this paper, it analyzed many met?ric data of social science journals included by JCR-Social Science Edition(JCRSSE)in 2012-2016, compared the metric data(especially self-citation)of journals from Brics countries with the international high-impact journals. It also analyzed the influence of the self-citation on the impact factors of these social science journals.[Result/Conclusion]The results showed that both impact factor and self-citation rate of the international high-impact journals were much better than those of Brics countries. The results also indicated that the Chinese journals included by 2014 JCRSSE had higher impact factors than those from other Brics countries. The self-citation rate of Chinese journals was lower than those of journals from Brazil, South Africa and Russia.%[目的/意义]期刊自引情况的研究对于分析期刊的研究方向以及评价期刊的学术质量有着重要的作用.[方法/过程]本文以2012-2016年《社会科学期刊引证报告》(JCR-Social Science Edition, JCRSSE)收录的社科类期刊的指标数据为样本,对国际高影响力期刊和收录的金砖五国(包括中国、印度、巴西、南非和俄罗斯)的社科类期刊进行了统计分析,并将这些期刊的指标数据(特别是自引情况)进行了比较研究,分析了自引情况对于社科类期刊影响因子的贡献.[结果/结论]研究结果表明,JCRSSE收录的国际高影响力期刊在影响因子和自引率方面均优于金砖五国的期刊.我国国际社科类期刊与其他金砖四国相比,在影响因子方面均高于金砖四国,且在自引率方面低于巴西、南非和俄罗斯.
