摘　　要：不同学科之间期刊影响因子的大小有非常大的变化,从相差数倍到相差上百倍。为探讨不同学科之间期刊影响因子有如此大差别的主要原因,使期刊影响因子既能体现学科内期刊的学术质量和影响力,也能较好地反映不同学科期刊之间的学术质量和影响力差别,本研究结合JCR数据从理论上分析了学科内期刊数量对期刊影响因子的影响。研究表明,期刊影响因子的大小随着学科内期刊数量的增加而增加,比较不同学科之间期刊影响因子的大小没有多大意义;对期刊影响因子计算方法提出了改进,改进方法较好地消除了期刊影响因子对学科内期刊数量的强烈依赖关系;改进的影响因子更客观、更有效、更合理,不仅能有效地反映期刊的学术质量和影响力,而且也使不同学科之间期刊的影响因子具有较合理的可比性。For interdisciplinary journals,there often exist great differences（from severalfold to several tenfold,or even to more than a hundredfold） among journal impact factors.In order to find why there is so large difference in impact factors among different disciplines and how to solve this problem,and to make journal impact factors reflect the difference of influence among not only intradisciplinary journals but also interdisciplinary journals,this paper theoretically studied the influence of journals＇ number on journals＇ impact factor based on the JCR data.The research results show that as a whole,the values of journal impact factors increase with the quantity of intradisciplinary journals increasing,and there is no much sense for comparing the impact factor of interdisciplinary journals.A new improved method for calculating journal impact factors was proposed in this paper,which can obviously discount the dependence of impact factors on journals＇ number,and the improved journal impact factors can effectively reflect the significance of journals and make the interdisciplinary comparison of journals become more valuable.
