摘要
利用分位数回归模型,分析平均引文数、平均作者数、地区分布数、海外论文比、基金论文比、期刊时效性对影响因子的影响,结果表明,海外论文比与影响因子无关;高影响因子和低影响因子期刊,平均引文数与期刊影响因子无关;高影响因子期刊,基金论文比与影响因子无关。认为影响因子影响因素分析有助于期刊评价指标选取,对于不同水平期刊的评价,评价方法可能不同。
This paper analyzes influences of average references per article, average number of authors, numbers of provinces, share of overseas contributions in total papers, share of grant-supported papers in total papers to impact factor based on quantile regression in order to assay impact factor' s influence at different level. The results show that share of overseas contributions in total papers is independent of impact factor. Average references per article is independent of impact factor when impact factor is higher or lower. Analyzing of impact factor' s influence is conducive to academic journal evaluation indicators. Evaluation of different levels should choose different evaluation methods.
