文章对《中国学术期刊影响因子年报》发布的学术期刊影响力指数(CI)进行了分析。理论分析结果显示非线性综合指标CI有引导期刊向指标优化组合方向发展的作用,而这是传统线性加权指标所不具备的。在分析结果的基础上,本文对CI提出如下改进思路:选取指标时,除了考虑指标自身的重要性,还要兼顾指标之间的独立性;处理指标时,除了进行归一化处理,还要加入修正因子以平衡指标提升难度的公平性;设定引导方向时,除了考虑数学上的合理性,更要符合期刊发展规律。
The paper analyzes the impact index (CI) of academic journals published in the Annual Report of Impact Factors of Chinese Academic Journals. The theoretical analysis shows that the non-linear CI has the function of leading journals to develop in the direction of optimal combination of indexes, which is not available in the traditional linear weighted index. Based on the analysis results, this paper proposes the following ideas for improvement of CI: When selecting indicators, apart from considering the importance of indicators themselves, they should take into account the independence between indicators. When dealing with indicators, in addition to normalization, Add the correction factor to balance the fairness of the index to enhance the difficulty; set the guiding direction, in addition to consider the mathematical rationality, but also to comply with the law of the development of periodicals.
