环境规制对长江经济带城市工业绿色发展效率的影响研究

基于2011～2016年长江经济带110个地级及以上城市面板数据,从环境规制对工业绿色发展效率的作用机理出发,采用空间杜宾模型探究环境规制对长江经济带城市工业绿色发展效率的影响效应。研究发现:环境规制对长江经济带城市工业绿色发展效率影响整体呈先抑制后促进的"U型"特征,绿色引导效应凸显需经历一定时期;环境规制对工业绿色发展效率的促进作用具有显著的地区异质性,整体呈下游、上游、中游地区梯度递减格局,且中游地区始终以成本约束效应为主;环境规制会导致污染型产业在长江经济带内城市间扩散转移,以中下游地区尤为突出,上游地区环境治理力度较弱而不足以影响企业迁移决策。进一步提升长江经济带城市工业绿色生产能力,应强化工业污染协同治理,提升环境政策精准性,加快绿色技术创新研发应用。

Impact of Environmental Regulations on the Cities’ Efficiency of Industrial Green Development in Yangtze River Economic Belt

Abstract：Based on the panel data of 110 cities in Yangtze River Economic Belt from 2011 to 2016, this paper explored the effect of environmental regulation on the cities’ efficiency of industrial green development by the spatial Durbin model from their inner theoretical mechanism. The results suggested several findings. The impact of environmental regulation on the cities’ efficiency took on a “U-shaped” trend, which first inhibited and then promoted. The green guidance effect needed to go through a certain period of time before appearing. Environmental regulation’s promoting effect presented significant regional heterogeneity, showing a gradient decreasing pattern in the downstream, upstream and middle reaches, and its cost constraint effect always dominated the middle reaches. Environmental regulation led to the diffusion and transfer of polluting industries among cities, especially in the middle and lower reaches. Environmental governance in the upper reaches was weak enough to affect the decision-making of enterprise migration. To further enhance the cities’ industrial green production capacity in Yangtze River Economic Belt, it is necessary to strengthen the coordinated treatment of industrial pollution, improve the accuracy of environmental policy, and accelerate the research and application of green technology innovation.
