世界一流大学竞争力与科研产出计量学特征的相关性研究

Research on the Relevance between Competitiveness and the Scientific Research Output of World-Class Universities

探究世界一流大学竞争力的核心要素,拟定正确的竞争力提升路径,对于建设世界一流大学具有重要意义。本文以世界大学综合排名前50位为样本,首先选择了具有代表性的9项科研产出计量学指标X1~X9进行统计分析,涉及生产力、影响力、贡献力、国际化水平4个维度。其次以X1~X9为自变量,各个大学在QS/USNEWS/THE/ARWU大学排名中的得分为因变量Yi,分别以4种多元线性回归模型Lasso/Ridge/LassoLars/BayesianRidge进行变量选择和参数估计试验,最终得出了较好的拟合效果。结果表明,世界一流大学科研产出的影响因子、总被引频次、篇均合作机构数量、国际合作年均频次与世界一流大学竞争力存在正相关关系,而年均论文数量、论文增长率、篇均合作作者数量、机构合作年均总频次、篇均合作国家频次与世界一流大学竞争力并无显著相关关系。

Exploring the core elements characterizing the competitiveness of world-class universities and formulating the correct path to its improvement is of great significance for building a world-class university.This article examines the top 50 universities in the World University Rankings as samples.First,nine representative research output measurement indicators,X1-X9,were selected for statistical analysis,which included the four dimensions of productivity,influence,contribution,and level of internationalization.Second,X1-X9 were set as the independent variables and each universityˇs score in the QS/USNEWS/THE/ARWU university rankings was established as a dependent variable,Yi.The variable selection and parameter estimation experiments were carried out with four multiple linear regression models,Lasso/Ridge/LassoLars/BayesianRidge,and finally a well-fitting effect was obtained.The results reveal positive correlations between the impact factors of scientific research output,the total citation frequency,the number of cooperation organizations,and the annual average frequency of international cooperation with the competitiveness of world-class universities.However,results also showed that the number of papers per year,the growth rate of papers,the number of co-authors,the total annual frequency of institutional cooperation,and the frequency of cooperation between countries are not significantly related to the competitiveness of world-class universities.
