期刊hc指数与hd指数的比较分析

A Comparative Analysis of Journal h_c-index and h_d-index

以CNKI为数据源,选取综合性社科类期刊为研究对象,实证对比分析了基于下载量的期刊h指数(hd指数)与基于引文量的h指数(hc指数)的分布特征及评价效果。结果显示:hd指数与hc指数具有较好的一致性,与期刊大部分的评价指标间都存在相关性;hd指数与hc指数都体现了最省力法则,评价结果价值取向相同、可比性强、具有一定的稳健性;hd指数在区分度、时效性、考察范围、稳健性等方面明显优于hc指数,而在严谨性方面hd指数则略逊于hc指数。

Based on the data pool of CNKI and taken comprehensive social science journals as research object,an empirical comparative analysis was conducted to evaluate the distribution characteristics and evaluating effectiveness of journal hc-index and hd-index,in which hc-index is based on downloads while hd-index on the number of citations. The results showed that hd-index was comparatively in accordance with hc-index in journal evaluation and they were relative with the most evaluating indexes of journals. Both hd-index and hc-index were in accordance with the rule of least-effort principle. Our results also showed that there was almost no difference in the value orientation of evaluation results obtained by hd-index or hc-index. Furthermore,the evaluation results obtained by hd-index and hcindex were highly comparative and relatively stable. In addition,hd-index had remarkable advantages of distinction degree,timeliness,survey scope,and stableness,etc. over hc-index but slightly inferior to hc-index in preciseness.
