：文章针对传统影响因子、被引频次、h指数在学术期刊评价中存在的问题，在有限目标、数量与质量兼顾、基本指标优化、时间轴一致、数据分布力求正态分布、防止人为操控原则的基础上，提出了一个新的文献计量指标--影响力指数，其原理是对被引频次和影响因子的自引现象进行修正，然后采用对数标准化后求和。基于图书馆情报与文献学CSSCI期刊的研究表明，影响力指数是个较好的文献计量指标，可以用来对学术期刊的短期影响力进行评价；对于期刊过度自引的修正系数，有待进一步研究。

In view of the problems of traditional evaluation index, such as impact factor, citation frequency and h-index, and taking into account of a series of principles like limited target, taking both quantity and quality into consideration, basic index optimization, time axis consistency, normal distribution data, and preventing artificial control, the author put forward a new bibliometric index, the influence index, so as correct the self-citation of cited frequency and impact factor, and then to sum up it after logarithmic normalization. Taking the CSSCI journal of library information and philology as research object, the research shows that the influence index is a good bibliometric index, which can be used to evaluate the short-term influence of academic journals. The correction coefficient of journal excessive self-citation needs to be further studied.
