基于Ypc＿EMM指数和Ypc＿EMM’指数的学者评价指标研究

Scholar Evaluation Research Based on Ypc＿EMM Index and Ypc＿EMM’ Index

[目的/意义]旨在为学者影响力评价提供参考。[方法/过程]阐述Ypc_EM类指数和EMM类指数的原理,利用现有相对成熟的理论及公式进行整合,构造出新的Ypc_EMM指数和Ypc_EMM′指数,并以兰州大学化学化工学院SCI引用TOP70研究人员为研究对象,对Ypc_EMM指数和Ypc_EMM′指数的区分性、稳定性和相关性进行实证分析。[结果/结论]Ypc_EMM指数和Ypc_EMM′指数的区分能力强于Ypc_EM指数和Ypc_EM′指数,且名次变化明显;Ypc_EM指数、Ypc_EM′指数、Ypc_EMM指数、Ypc_EMM′指数四者与h指数都具有较强的相关性,且改进后的Ypc_EMM指数和Ypc_EMM′指数对学者影响力评价更加全面、客观。

[Purpose/significance]The paper is to provide references for the evaluation of scholars’influence.[Method/process]The paper expounds the principles of Ypc_EM class index and EMM class index constructs new Ypc_EMM index and Ypc_EMM′index by integrating the existing and relatively mature theories and formulas and takes Top70 researchers from the college of Chemistry and Chemical Engineering of Lanzhou University and included in SCI as study objects to do empirical analysis on the differentiation stability and correlation of Ypc_EMM index and Ypc_EMM′index.[Result/conclusion]Ypc_EMM index and Ypc_EMM′index are more distinguishable than Ypc_EM index and Ypc_EM′index and their rankings change apparently.The four indexes including Ypc_EM index Ypc_EM′index Ypc_EMM index and Ypc_EMM′index have strong correlation with h-index and the improved Ypc_EMM index and Ypc_EMM′index are more comprehensive and objective in the evaluation of scholars’influence.
