中文摘要: 通过对JCR各学科5459种期刊的被引用指标进行统计学分析,发现不同学科之间存在显著差异,同学科内不同领域之间的期刊也存在显著差异。因此,在涉及到使用影响因子的时候,用影响因子的绝对值对不同学科/领域的期刊进行比较是不合适的。对科研人员的考核而言,用所谓的前15%或30%来进行考核也不合适,因为不同领域JCR收录的期刊数不一样,这种差异是基于SCI数据库的结构,不是出于学科在科学上的重要性,这对于被SCI收录数量少的领域的科学家是不公平的。因此,建议使用影响因子的相对值进行绩效考核,即对影响影子先进行标准化处理,方法是将目标期刊的影响因子除以该领域期刊影响因子的平均值,得到相对值,使不同学科、同一学科不同领域的期刊具有可比性。
Abstract:The author analyzed statistically the citation indexes of 5 459 journals listed in JCR of SCI,and found significant differences among different disciplines and also significant differences among different journals of different fields in the same discipline.Therefore,for the purpose of journal evaluation,it is not appropriate to use absolute values of journal impact factor for the comparison of journals of different disciplines and/or fields.For purpose of the evaluation of scientist achievements,it is not appropriate and unfair to use so-called top 15% or 30% journals,because the number of journals covered by SCI differs among academic fields,and this kind of difference is based on the structure of SCI database,not on the significance of science.Therefore,it is suggested to use relative impact factor for the achievement evaluation.Firstly,to standardize the impact factor of SCI,i.e,make the target journal impact factor divided by the mean impact factor of specific filed or discipline,so as to get a relative value,and this relative value can be used for the comparison of journals of different disciplines and /or different fields in the same discipline.
