基于合著作者贡献大小分配权值的p指数探讨

目的/意义] 为了合理平衡合著论文中作者的科研贡献，在总结前人p指数计算方法的基础上，针对合著论文作者署名次序与作者贡献均等问题，提出基于合著作者贡献大小分配权值的p指数方法，以使p指数用于人才评价时更加有效合理。方法/过程] 以图书情报学领域两位作者的科研论文产出为例，通过数据统计与对比分析得出4种不同p指数方法的计算结果。结果/结论] 发现只考虑独著和第一作者发文情况的p₁指数与不考虑合著只要参与就计一次的p₂指数属于极端的处理方式；而按均分合著者权重计算的p_a指数忽略了著者署名次序的问题；根据娄策群的作者贡献率等级分配法计算所得的p_w指数不仅考虑到作者合著情况，还考虑到对于一篇科研论文处于不同署名位次的作者贡献率不同。因此，根据贡献大小分配权值的p_w指数更具有客观合理性。

Discussion of P-index Based on the Co-author Contribution Division Value

Purpose/significance] In order to reasonably balance the co-authors' research contribution, this article summarizes predecessors' calculation method of p-index and aims at analyzing the co-authorship phenomenon and solving author signature sorting problems of the paper. Then, we present four calculation methods of p-index based on the co-author contribution division value, making the p-index for scientific research evaluation more effective and reasonable. Method/process] Taking two experts in the field of library and information science as examples, we compared and analyzed the results of four kinds of different calculations by data statistics and calculation.Result/conclusion] It finds out the two p-index calculation methods. One method only considers the situation of individual writing and the first author and the other method does not consider the situation of the co-authorship phenomenon. These two methods belong to the extreme treatments. The p_a-index which averagely distributes the co-author weight ignoring the author signature sorting problem. The p_w-index calculated by Lou Cequn's author contribution rate levels distribution method not only takes the co-authorship phenomenon into account, but also considers the different author contribution rate in different author signature ranking. Therefore, the p_w-index based on the co-author contribution division value is more objective and rational.
