摘要
以2011年JCR土壤学期刊为例,首先采用因子分析将传统期刊评价指标分为影响力与时效性两个公共因子,然后采用传统回归和分位数回归研究特征因子与期刊影响力与时效性的关系。研究结果表明:特征因子分值与期刊影响力有关,与期刊时效性无关;对特征因子分值较高的期刊而言,特征因子与期刊影响力的相关系数较低,反之亦然;论文影响分值既与期刊影响力相关,也与期刊时效性相关,但更多地体现了期刊的影响力,对期刊的时效性体现不足。对于其他学科期刊特征因子与影响力、时效性的关系有待进一步研究。
Selecting soil journals from JCR 2011 as an example,this paper divides traditional journal evaluation indexes into impact factor and novelty factor based on factor analysis,then analyzes the relationship between Eigenfactor and impact factor novelty factor according to traditional regression and quantile regression.The results show,first,Journal Eigenfactor Score is related to impact factor and independent of novelty factor.The correlation degree of Eigenfactor Score and impact factor is lower while Eigenfactor Score is high.The correlation degree of Eigenfactor Score and impact factor is higher while Eigenfactor Score is low.The article influence score is related both to impact factor and novelty factor but the contribution is mainly impact index.It needs more study in other subjects.
