异质性治理主体视角下环境规制的治污路径——基于中介效应的空间差异分析

A PATH TO POLLUTION CONTROL UNDER ENVIRONMENTAL REGULATIONS VIEWING FROM HETEROGENEITY GOVERNANCE BASED ON SPATIAL DIFFERENCE OF MEDIATING EFFECT

为明晰异质性治理主体视角下环境规制对污染排放的作用机制,将环境规制工具分为政府强制型和公众参与型两种,构建空间杜宾模型验证环境规制的治污作用,并以技术创新和工业总产值为中介变量,探讨不同地区环境规制的治污路径。结果发现:1)中、东部地区公众参与型环境规制与污染排放显著负相关,比政府强制型环境规制更能起到抑制污染的作用;2)西部地区政府强制型环境规制与污染排放显著负相关,且工业总产值的中介作用显著,要防止其成为东部污染产业转入的“避难所”;3)技术创新在两种环境规制与污染排放之间的中介作用均不显著,但技术创新和公众参与的空间溢出效应显著,在地区间具有学习效应。

To study role of environmental regulations on pollution emission under heterogeneity governance, this paper divides environmental regulations into two types, government-enforced and public-involved, which are used to establish a spatial Dubin model to test the pollution controls of environmental regulations. Technical innovation and gross industrial production are served as medium variables to discuss the paths to pollution of environmental regulations in difference areas. Public-involved environmental regulation in central and eastern China is closely related to pollution emission, better than government-enforced. Government-enforced environmental regulation in western China is outstandingly negative to pollution emission, with gross industrial production playing a stronger moderating role, which needs to be prevented from being asylum for eastern pollution industries. Technical innovation plays a little mediating role on environmental regulation and pollution emission, but its spatial overflow effect is great, so is public-involved environmental regulation, with a learning effect across different areas.
