选取了13个常用定量的期刊评价指标,并增加了一个“历史影响因子”。利用主成分分析将指标进行系统分类再基于期刊评价指标建立结构方程模型来探讨这些指标之间存在的结构关系,发现影响因子、他引影响因子、5年影响影子、即年指标、平均引文数、web即年下载率、历史影响因子之间存在结构关系,综合总被引、可被引文献量、引用期刊数、被引期刊数、总下载量之间存在结构关系,可被引文献比、基金论文比存在结构关系,然而平均引文数,可被引文献比的可信度偏低,可以适当考虑减轻其在期刊评价中所赋予的权重。同时验证了历史影响因子作为期刊评价指标的重要性,另外发现影响因子和5年影响因子具有高度相似性,由于两者都为流量指标,所以建议期刊评价指标选取时两者选其一即可。
Selected 13 commonly used quantitative journals evaluation index, and added a “historical impact factor ”. The principal component analysis was used to classify the indicators systematically. Then, the structural equation model was established based on the journal evaluation index to explore the structural relationship between these indicators. It was found that the influencing factors, the influencing factors, the shadow of 5 years influence, the annual index, the average number of citations , There is a structural relationship between the annual download rate of web and the historical impact factors, the total number of citation cited, the number of cited citation, the number of cited journals, the number of cited journals, and the total downloaded volume, However, there is a structural relationship between theses and theses, however, the average citations and the census of citation may be less credible, and the weight given to them in the evaluation of journals may be properly considered. At the same time, it verifies the importance of historical influencing factors as evaluation index of periodicals. In addition, we find that the influencing factors are highly similar to the five-year influencing factors. Because both of them are traffic indexes, it is suggested that either .
