区域R&D投入、产学研耦合协调度与科技绩效

基于耦合协调度测度模型、主成分分析以及面板门限回归模型，运用2013~2017年我国30个省市的面板数据，以产学研耦合协调度为门限变量，将区域R&D投入划分为R&D人员投入与R&D经费投入，探究R&D人员投入与R&D经费投入对科技绩效产生的异质性影响。实证结果表明：当以产学研耦合协调度为门限变量时，R&D人员投入与R&D经费投入均与滞后3期的科技绩效存在明显的双门限效应；R&D人员投入对科技绩效的正向作用随着门槛值的提升不断增大，当产学研耦合协调度高于0.6135时，R&D人员投入对科技绩效产生显著的正向作用；R&D经费投入对科技绩效并不总是产生正向促进作用，当区域产学研耦合协调度小于0.5290时，R&D经费投入会对科技绩效产生负向作用；当区域产学研耦合协调度高于0.5290时，R&D经费投入对科技绩效产生正向作用；并且，R&D人员投入对科技绩效产生的作用更为显著。

Regional R&D Investment,Industry-University-Research Coupling Coordination and Scientific and Technological Performance

Based on the coupling coordination degree measurement model, principal component analysis, and the panel threshold regression model, using the panel data of 30 provinces and cities in China from 2013 to 2017, taking the coupling degree of industry, university, and research as the threshold variable, this paper explores the heterogeneous impact of R&D staff input and R&D funding on technology performance by dividing regional R&D investment into R&D personnel input and R&D expenditure. The empirical results show that when the coupling degree of industry, university, and research is used as the threshold variable, there is a significant double threshold effect on the R&D personnel input and the R&D expenditure and a three phases of the scientific and technological performance. There is a positive effect of R&D personnel input on the scientific and technological performance when the threshold value increases. When the coupling degree of industry, university, and research is higher than 0.6135, the R&D personnel input has a significant positive effect on the scientific and technological performance. R&D expenditure does not always positively promote the performance of science and technology. When the coupling degree of industry, university, and research is less than 0.5290, the R&D investment will have a negative effect on the scientific and technological performance. When the regional industry, university, and research coupling coordination degree is higher than 0.5290, the R&D expenditure will have a positive effect on the scientific and technological performance, and the role of R&D personnel in investment in the scientific and technology performance is more significant.
