摘　　要：为弥补z指数无法区分合著作者贡献率的缺陷,提出3种基于署名顺序分配合著作者贡献权值的改进z指数,以提高利用z指数评价学者学术影响力的有效性和全面性。将几种基于署名的合著作者贡献测度算法引入z指数,以muscular dystrophy领域具有代表性的学者作为研究对象,从描述性统计结果分析、学者排名情况、相关性、典型情况分析等维度比较分析zhc指数、zgc指数及zac指数评价效力。结果表明:zhc指数、zgc指数及zac指数均能体现合著作者贡献大小,但是zgc指数对总作者数少于10位且排名靠前的作者贡献更加偏重,zac指数对总作者数相对较多且署名顺序相对靠后的作者贡献相较友好,而zhc指数对被引量不同的论文的作者位次变化较为敏感,且这3个指数均能在不同程度抑制“挂名”及“互挂”现象的滋生。In order to make up for the deficiency of z-index which cannot distinguish the contribution rate of co-authors, this paper proposes three improved z-indexesso as to improve the effectiveness and comprehensiveness of using z-index to evaluate the academic influence of researchers. This paper introduced the signature sequenceinto z-index.By taking 20 leading researchers in the field of muscular dystrophy as an example, the effectiveness of zhc-index, zgc-index and zac-index was analyzed by descriptive statistics, ranking of scholars, correlation and typical analysis. The conclusion is that zhc-index,zgc-index and zac-index all reflect the contributions of co-authors. But the zgc-index is more favorable to the contribution of authors of the highest authorshipand to cases where there were fewer than 10 co-authors.The zac-index is friendly to the contributions of authors of a relatively lower authorship and to cases with a relatively bigger number of authors. The zhc-index in contrast is sensitive to author ranking of authors whose amount of papers citations are different. And all three indexes can help to curb the phenomenon of academic “nominal name” and “nominal name each other” in different degrees.
