环境规制与皖江经济带的绿色发展——基于经济效应及空间外溢效应的考察

Environmental Regulation and the Green Development of Wanjiang Economic Belt——Based on the economic effect and spatial spillover effect

基于皖江经济带9个城市2011—2020年的面板数据,建立时间空间双固定效应的空间杜宾模型分析环境规制对城市绿色全要素生产率的非线性影响及空间溢出效应。研究发现:环境规制显著持续提高本地区的绿色全要素生产率,从空间溢出视角揭示环境规制与相邻地区的绿色全要素生产率间存在显著“U”型关系。从长期来看,环境规制对城市绿色全要素生产率的影响及空间溢出效应均显著为正,表明环境规制的空间协同治理显著提升皖江经济带区域的绿色协调发展。地方政府应充分考虑地区经济发展差距,制定差异化的环境规制政策,动态调整环境规制的政策力度;强化绿色技术创新研发力度,实现本地和邻近区域绿色技术创新资源和成果的共享;探索构建跨市协同生态文明建设的机制,优化资源配置,促进皖江经济带绿色全要素生产率不断提升。

Based on the panel data of nine cities in Wanjiang Economic Belt from 2011 to 2020,a spatial Durbin model with time and space double fixed effects is established to analyze the nonlinear impact of environmental regulation on urban green total factor productivity and the spatial spillover effect.Research has found that environmental regulations significantly and continuously improve the green total factor productivity of the local area,revealing a significant "U" shaped relationship between environmental regulations and the green total factor productivity of adjacent regions from the perspective of spatial spillovers.In the long run,the impact of environmental regulations on urban green total factor productivity and spatial spillover effects are significantly positive,indicating that the spatial collaborative governance of environmental regulations significantly improves the green coordinated development of the Anhui River Economic Belt region.Local governments should fully consider the regional economic development gap,formulate differentiated environmental regulation policies,and dynamically adjust the policy strength of environmental regulation;Strengthen the research and development efforts of green technology innovation,and achieve the sharing of local and adjacent green technology innovation resources and achievements;Explore the mechanism for building cross city collaborative ecological civilization construction,optimize resource allocation,and promote the continuous improvement of green total factor productivity in the Anhui River Economic Belt.
