Abstract: Based on the coupling model of industry-university-research coupling degree, principal component analysis and panel threshold regression model, using the panel data of various provinces and cities in China in 2012-2016 to study the input of scientific and technological human resources to regional innovation performance impact when the coupling of production, education and research as the threshold variable.The empirical results show that when the coupling degree of production, study and research is used as the threshold variable, the input of scientific and technological human resources in enterprises and universities and research institutes will have obvious double threshold effect between the three periods of regional innovation performance; when the coupling degree is higher than 0.7324, investing in scientific and technological human resources in enterprises will have a significant positive impact on regional innovation performance. When the degree is lower than 0.7324,it will have a relatively weak positive impact . When the degree of coupling is higher than 0.6120, investing in scientific and technological human resources in research institutes and universities will have a significant positive impact on regional innovation performance. When the degree is lower than 0.6120, it will have a relatively weak positive impact ; and when the degree is higher than 0.6120, the investment in scientific and technological human resources in universities and research institutes will have a greater impact on regional innovation performance than in the enterprise.

摘要： 基于产学研耦合度测度模型、主成分分析以及面板门限回归模型，运用2012-2016年我国各省市面板数据，研究以产学研耦合度为门限变量时，科技人力资源投入对区域创新绩效产生的影响。实证结果表明：当以产学研耦合度为门限变量的情况下，企业和高校科研院所投入的科技人力资源均会与滞后三期的区域创新绩效间产生明显的双门限效应。当耦合度高于0.7324时，在企业中投入科技人力资源会对区域创新绩效产生显著的正向影响；当耦合度低于0.7324时，在企业中投入科技人力资源会对区域创新绩效产生相对微弱的正向影响。当耦合度高于0.6120时，在高校与科研院所中投入科技人力资源会对区域创新绩效产生显著的正向影响；当耦合度低于0.6120时，在高校与科研院所中投入科技人力资源会对区域创新绩效产生相对微弱的正向影响。且当耦合度高于0.6120时，在高校与科研院所中投入科技人力资源对区域创新绩效产生的影响高于在企业中投入科技人力资源所产生的影响。
