[目的/意义]分析JCR最新公布的“影响因子百分位”指标的特点以及其对期刊评价的影响。[方法/过程]从影响因子百分位的内涵分析入手,比较其与影响因子的统计学特征,在因子分析的基础上,采用多元回归和分位数回归研究影响因子百分位与其他文献计量指标之间的关系,同时采用Spearman相关系数分析其与其他文献计量指标的关系。[结果/结论]研究结果表明,影响因子百分位改变了影响因子的统计学特征;影响因子较低的一些期刊,转换成影响因子百分位后相对值更低,其他期刊转换成影响因子百分位后相对值更高;影响因子百分位与其他文献计量指标相关程度中等;当影响因子百分位较低时,影响因子相关指标的弹性系数较高,当影响因子百分位处于中等时,总量指标及特征因子指标的回归系数较低;影响因子百分位并不适宜作为其中一个指标用于期刊多属性评价。
[Purpose / Significance] To analyze the characteristics of the “Impact Percentile” index published by JCR and its impact on journal evaluation. [Methods / Processes] Starting from the connotation analysis of the percentile of influencing factors, the statistical characteristics of influencing factors and the statistical characteristics of influencing factors were compared. Based on the factor analysis, multiple regression and quantile regression were used to study the percentile of influencing factors and other literatures The relationship between indicators was measured, and Spearman correlation coefficient was used to analyze the relationship between the indicators and other indicators. [Results / Conclusion] The results showed that the percentile of the influencing factors changed the statistical characteristics of the influencing factors. In some of the lower influencing factors, the relative percentiles were lower after the percentile of the influencing factors was converted to other percentiles. Other journals were converted into influencing factors The relative value of the percentile is higher; the percentile of the influencing factor is moderately correlated with other literatures; when the percentile of the influencing factor is low, the elasticity coefficient of the relevant index of the influencing factor is higher. When the percentile of the influencing factor is in In the medium, the regression coefficients of the total quantity index and the characteristic factor index are low; the percentile of the influencing factor is not suitable as one of the indexes for the multi-attribute evaluation of the journal.
