环境规制与绿色全要素生产率:以南通为例

Environmental Regulation and Green Total Factor Productivity:Taking Nantong as an Example

本文基于动态空间面板模型从全局性与异质性进行实证研究,结果表明:研究期内强化环境规制对南通市绿色全要素生产率呈正向效应,但未能通过显著性检验。全面深化改革后,强化环境规制对南通市绿色全要素生产率的提升具有显著促进作用,2014—2019年时段内绿色全要素生产率表现出显著的动态连续性与空间趋同特性。EKC理论未获得南通市数据支持,南通市经济发展与绿色全要素生产率之间呈U型发展关系,当前处于U型曲线右边,表明南通市已越过拐点。据此,提出相关对策建议。

Based on the dynamic spatial panel model,this paper conducts an empirical study from the perspective of globality and heterogeneity.The results show that the strengthening of environmental regulation during the study period has a positive effect on the green total factor productivity of Nantong City,but it fails to pass the significance test.After comprehensively deepening the reform,the strengthening of environmental regulation has a significant role in promoting the improvement of green total factor productivity in Nantong City.During the period from 2014 to 2019,green total factor productivity showed significant dynamic continuity and spatial convergence characteristics.The EKC theory has not been supported by the data of Nantong City.The relationship between Nantong's economic development and green total factor productivity is a U-shaped development relationship,which is currently on the right side of the U-shaped curve,indicating that Nantong City has passed the inflection point.Accordingly,relevant countermeasures are proposed.
