校企合作对我国省域高校科研效率的影响研究——基于门槛回归的经验证据

Research on the Influence of University-industryCollaboration on the Scientific Research Efficiency of Provincial UniversitiesBased on the Empirical Evidence of Threshold Regression

基于2010—2017年我国30个省域高校的面板数据,运用DEA-BCC模型测算高校科研效率,以校企合作强度作为门槛变量,采用门槛回归方法实证研究校企合作对高校科研效率的影响。研究结果表明,校企合作对高校科研效率的影响存在双重门槛效应,可划分为三个区间,在校企合作中等强度区间内,校企合作对科研效率起正向影响作用,过高或过低都会产生负向影响作用。门槛值为校企合作对科研效率作用的结构突变点在第一门槛值两侧影响关系呈"正U型"变动趋势,在第二门槛值两侧呈"倒U型"变动趋势。高校应进一步提高校企合作水平。

Based on the panel data of 30 provincial universities in China from 2010 to 2017,DEA-BCC model is used to measure the research efficiency of universities.Taking the intensity of university-industry collaboration as the threshold variable,threshold regression method is used to empirically study the impact of university-industry collaboration on the research efficiency.The results show that there are double threshold effects,which can be divided into three sections.In the middle intensity,university-industry collaboration has a positive impact on the research efficiency,and too high or too low will have a negative impact.The threshold value is the structural mutation point of the effect.The relationship between the two sides of the first threshold shows a"positive U-shaped"change trend,and the relationship between the two sides of the second thresholdshows an"inverted U-shaped"change trend.With the development of economy and society,the university-industry collaboration should be further strengthened.
