基于z指数的科研机构评价的有效性实证研究

Application of Z-index to Institutions Evaluation

[目的 /意义]对基于z指数的科研机构评价有效性进行实证研究,旨在为科学合理地评价科研机构学术影响力探寻新的视角和方法。[方法 /过程]本文采用新的综合性评价指标——z指数,以Muscular Dystrophy研究领域最具代表性的25家机构为样本,通过计算分析目标数据的z指数、h指数、p指数、总发文量、总被引次数和平均被引率、一致性指标η,验证了利用z指数评价机构学术影响力的有效性。[结果/结论]结果表明z指数是一个3D效能指标并具有高灵敏性和稳定性。同时也指出z指数存在诸如低引用长尾严重影响z指数大小、高核区论文被引的增加会对z指数产生副作用、忽略专利等其他科研形式的作用的缺陷,为后续研究奠定基础。

[Purpose/Significance] Application of z-index to institutions evaluation aimed to explore new perspectives and methods for scientific and rational evaluation η of institutions. [Method/Process] In this paper,the z-index hat was used to calculatet the h-index,the p-inedx,the number of articles,the citation frequency,the average citation frequency and the consistency term of core institutions in muscular dystrophy. And the relevance was analyzed. The paper used an empirical study to analyze the effect of z-index in institutions evaluation. [Result/Conclusion] Results showed that zindex was a measure that combines all three attributes,namely,quality,quantity,and consistency into a single number and was high sensitivity and stability. However,this paper found that z-index had also disadvantage such as low citing long tail seriously affects the size of z-index,the increased citation of high core papers would have a side effect on the z-index and ignoring the role of other forms of scientific research such as patents,which laid the foundation for future research.
