摘　　要： 针对h指数灵敏度差、不能反映高影响力施引论文重要性这两项弱点,推导一个新的类h指数——h2指数。从两方面实证h2指数的可靠性:即通过对近10年电子商务领域SCI收录高被引论文实证分析,得出h2指数与h指数有很强的一致性,并且前者具有较高灵敏度;h2指数与词频分析法相结合选出的电子商务领域高频关键词,证实与2010年国家自然科学基金电子商务类已成功申报项目较好吻合。 H index has been widely used to assess the level of scholars and their papers, but it is lack of susceptiveness and can＇ t reflect the importance of high impact citing articles. Taking these two points into account, the paper derives a new kind of H index-- h2 index. It makes an empirical research through two aspects. On one hand, there is a good consistency between h - index and h2 index with analysis of high impact citing articles of e - business in the past ten years, and h2 index is more sensitive than h - index. On the other hand, key words in high frequency choosed from h2 index and word frequency analysis coincide with programs of the grant of Natural Science Foundation in 2010.
