环境规制、绿色创新与环境污染关系实证研究

Environmental Regulation-Empirical Study on the Relationship between Green Innovation and Environmental Pollution

借用空间计量及面板门限模型,聚焦环境规制、绿色创新与环境污染之间的关系,研判环境规制调节效应可能存在的门槛效应,洞悉区域治理的差异性。研究表明:环境规制、绿色创新是中国省市环境污染治理的关键要素,存在直接抑制及抑制溢出双重效应;环境规制强化了绿色创新对地区环境污染的直接抑制及抑制溢出效应,但存在门槛效应。进一步异质性研究表明:中国沿海省市环境治理主要依靠绿色创新,并逐步弱化环境规制为主的行政命令治理方式,采用与市场相结合的环境治理模式,但中西部内陆省域受制于产业结构及科技水平,环境治理仍旧依靠政府行政命令。

By using spatial metrology and panel threshold model,this study focuses on the relationship between green innovation,environmental regulation and environmental pollution,studies the potential threshold effect of regulatory effect of environmental regulation,and provides insight into the differences of regional governance.The research conclusion shows that:Firstly,green Innovation and environmental regulation are the key factors of environmental pollution governance in China’s provinces and cities;and there exist the dual effects of direct inhibition and inhibition spillover.Besides,environmental regulation strengthens the dual effects of direct inhibition and spillover inhibition of green innovation on regional environmental pollution,but this regulatory effect has a single threshold effect.Further heterogeneity research shows that the main factors of environmental governance in China’s coastal provinces and cities refer to green innovation,gradually weakening the administrative mode based on environmental regulation,and adopting the environmental governance mode combined with market.However,the central and western inland provinces are subject to the industrial structure and the level of science and technology,the environmental governance still depends on the administrative government.
