期刊自引与影响因子关系的分区比较与历时分析——以JCR收录的管理学期刊为例

Relationship between journal self-citation and impact factor based on quartile ranking comparison and diachronic analysis:Taking management journals indexed by JCR as examples

【目的】考察期刊自引程度以及期刊自引对期刊影响因子的影响程度,并揭示其动态变化规律。【方法】以2009—2018年JCR收录的管理学期刊为例,对期刊自引率(自引证率和自被引率)与影响因子(剔除自引前、后)共计4种指标及其关系进行分区比较和历时分析。【结果】自引证率保持基本稳定而自被引率先增后降,自引对影响因子确有影响但程度有限,自引率与影响因子不具有普遍的相关关系,上述指标的分布和变化规律在不同分区存在显著差异。【结论】管理学期刊的自引程度没有加剧,自引对影响因子的影响程度也没有增强,应对期刊自引持乐观和谨慎的态度。

[Purposes]This paper aims to investigate the degree of journal self-citation( JSC) and its influence on impact factor( IF),so as to track their dynamic changes. [Methods] Taking the journals in the category of management indexed by JCR as samples,this study investigated the annual values of four indicators,including self-citing rate( SRR),self-cited rate( SCR),IF( with JSCs),and IF0( without JSCs),and detected their relationships by quartile ranking comparison and diachronic analysis.[Findings]Across the last decade,SRR remained stable,while SCR showed an upward trend before 2012 but a downward trend after 2012. JSCs do have an influence on IF,but to a limited extent. There is no universal correlation between JSC rate and IF in every quartile. Moreover,the distribution and change rules of the above indicators are significantly different in different quartiles.[Conclusions]It reveals a favorable publishing environment in management journals. Both the degree of JSC and its influence on IF have not intensified. We should treat JSC optimistically and cautiously.
