环境管制、知识产权保护与区域创新能力——基于我国省际面板数据的实证研究

Environmental regulation,intellectual property protection and regional innovation capabilities:An empirical study based on provincial panel data in China

文章基于政府主导视角,利用2006—2015年我国30个省级面板数据,构建多元回归模型,分析变量之间的关系。其结果显示,环境管制、知识产权保护与区域创新能力之间呈非线性关系,环境管制与知识产权保护同时实施对区域创新能力有显著的促进作用,且具有区域异质性。从企业生存角度出发,提出门槛效应假说,采用Hansen面板门槛回归模型进行检验。结果表明,在环境管制与知识产权保护共同发挥作用时,环境管制必须控制在合理的范围内。最后采用门槛效应回归方法找到了环境管制与知识产权保护对区域创新能力影响的门槛值,并提出相应的政策建议。

Based on the government’s dominant perspective,this paper uses the 30 provincial-level panel data from 2006 to 2015 to construct a multivariate regression model and analyze the relationship between variables.The results show that there is a non-linear relationship between environmental regulation,intellectual property protection and regional innovation capability.The simultaneous implementation of environmental regulation and intellectual property protection has a significant role in promoting regional innovation capability and regional heterogeneity.From the perspective of enterprise survival,the threshold effect hypothesis is proposed and tested by Hansen panel threshold regression model.The results show that when environmental regulation and intellectual property protection work together,environmental regulation must be controlled within a reasonable range.Finally,this paper uses the threshold effect regression method to find the threshold of the impact of environmental regulation and intellectual property protection on regional innovation capabilities,and puts forward corresponding policy recommendations.
