学术期刊自引率与自被引率指标的改进与结合分析

Improvement and combination analysis of self-citing rate and self-cited rate indicators of academic journals

【目的】对学术期刊自引率与自被引率指标进行改进和结合分析,了解新时期图情档领域期刊自引特征,为其他领域期刊自引分析提供参考。【方法】通过比较分析,设计两年自(被)引率、两年自(被)引比等指标,结合自引率与自被引率提出期刊四分类模型(独立型、普通型、开放型、权威型);运用文献计量法对2012—2021年图情档CSSCI来源期刊进行实证分析。【结果】2012—2021年,图情档领域发文量呈明显的下降趋势,但是自(被)引率逐年增加,两年自(被)引率相对稳定。整体上,各期刊的两年自(被)引率要高于自(被)引率,两年自(被)引比较高。图书馆学期刊自(被)引率相对较低,情报学期刊自(被)引率较高,2种档案学期刊的自(被)引率最高。通过绘制期刊自引率与自被引率坐标图,可将期刊归为四大类。【结论】期刊两年自(被)引率、两年自(被)引比、四分类模型具有较好的实用性,能深入揭示期刊自引特征。大部分图情档领域期刊属于独立型和开放型两大类型。

[Purposes]The self-citing rate and self-cited rate indicators of academic journals are improved and combined to understand the self-citation characteristics of journals in the field of library,information,and archives in the new era and to provide a reference for the analysis of self-citation of journals in other fields.[Methods]Firstly,the indexes such as two-year self-citing(cited)rate and two-year self-citing(cited)ratio were proposed,and a four-type classification model of journals(independent,ordinary,open,and authoritative)was developed based on the self-citing rate and self-cited rate indicators.Then,empirical analysis was conducted on the CSSCI journals in the field of library,information,and archives from 2012 to 2021.[Findings]From 2012 to 2021,the number of articles published in the field has shown a downward trend.However,the self-citing(cited)rate has been on the rise,and the two-year self-citing(cited)rate is stable.Overall,the two-year self-citing(cited)rate of each journal is higher than the self-citing(cited)rate,and two-year self-citing(cited)ratio is relatively high.Library science journals have low self-citing(cited)rates,while information science journals have high self-citing(cited)rates.The two archival science journals have the highest self-citing(cited)rates.According to coordinate map of self-citation(cited)rate,journals can be classified into four categories.[Conclusions]Two-year self-citing(cited)rate,two-year self-citing(cited)ratio,and four-type classification model well reflect the self-citation characteristics of journals,which are more practical.Most journals in the field of library,information,and archives belong to two types:independent and open.
