期刊影响力指数排名的合理性分析

Analysis of rationality on the ranking of academic journal clout index

【目的】探讨期刊影响力指数的科学合理性及其可能存在的不足,以利于决策者、办刊人以及作者更加科学地评估学术期刊影响力,预测期刊发展潜力。【方法】以2015—2017年《中国学术期刊影响因子年报》的10个期刊指标数据为研究对象,运用IBM SPSS软件,采用主成分分析法,求得各期刊的综合主成分得分(F),按照F对期刊进行排名;将F与期刊影响力指数(fCI)排名结果进行对比分析;采用Spearman秩相关系数,比较fCI和F与10个指标的相关程度。【结果】F与10个指标的相关性总体高于fCI;fCI和F与即年指标的相关系数相对较小,但是F明显高于fCI。【结论】F排名更接近各项指标共同表征的期刊水平;更能反映期刊的反应速率和被引强度;在参阅期刊fCI排名时,应当特别注意参考期刊的即年指标。

[Purposes] This paper aims to explore scientific rationality and possible inadequacies of academic journal clout index（ CI） to help decision-makers,publishers,and authors to evaluate the influence of academic journals and predict the development potential of journals. [Methods] Taking the data of ten journals＇ indexes from Annual Report for Chinese Academic Journal Impact factors（ Natural Science）（ 2015-2017） as objects,we ranked the journals according to every journal＇ s comprehensive principal component score（ F） by principal component analysis in IBMSPSS software. Results of F-ranking and CI-ranking were compared and the differences were analyzed. The Spearman rank correlation coefficient was applied to compare the correlation between fCIand F with each of the ten journals＇ indexes. [Findings] The F has closer correlation with the ten journals＇ indexes than those with fCI.Immediacy index has lower correlation coefficient with both F and fCIthan the other indexes,while the correlation coefficient with F is higher than that with fCI. [Conclusions] The F can better represent the ten journals＇ indexes than fCI. Thus F-ranking is much closer to the level of journals reflected by all ten journals＇ indexes. F-ranking has advantage of fCI-ranking to showjournals＇ reaction rate and citation intensity,and to indicate journals＇ latest development trend and vitality. Immediacy index of journals should be considered when the CI-ranking is consulted.
