环境规制与长江经济带工业绿色转型--基于排污异质性的视角

Environmental Regulation and Industrial Green Transition in the Yangtze River Economic Belt: From the Perspective of Emission Heterogeneity

加快推动工业绿色转型是促进长江经济带全面绿色低碳发展的必由之路和关键抓手。以长江经济带为样本考察环境规制对工业绿色转型的排污异质性影响效应,结果表明,环境规制对长江经济带工业绿色转型存在正向促进效应,符合“波特假说”,且这种影响存在排污异质性特征,表现为排污强度越高的地区促进作用越强。进一步研究表明,这种影响还存在非线性和门槛特征,其中,环境规制对长江经济带整体工业绿色转型的影响呈现“J”形特征,对轻污染和重污染省市的影响均呈“U”形关系,对中污染省市的影响则不显著。此外,2016年起实施的长江经济带绿色发展战略有效增强了环境规制对长江经济带工业绿色转型的促进作用。总体上,长江经济带环境规制强度偏低,政策效应尚未充分发挥。进一步深入推进长江经济带工业绿色转型,应以排污异质性特征为重要参考,分类分区制定具有针对性的环境规制政策,加快构建环境规制区域协商机制,促进环境规制政策不断丰富和动态优化调整。

Accelerating industrial green transformation is the only way and key to promote the comprehensive green and low-carbon development of the Yangtze River Economic Belt.In the Yangtze River Economic Belt as sample investigation of environmental regulation to the transformation of the industrial green emission heterogeneity effect,the results showed that the environmental regulation of the Yangtze river Economic Belt has positive promoting effect on industrial green transformation,in line with the"Porter hypothesis",and this effect is heterogeneity characteristics that show the higher emission intensity region promoting effect.Further research shows that this influence also has nonlinearity and threshold characteristics.Among them,environmental regulation has a J-shaped influence on the overall industrial green transition of the Yangtze River Economic Belt,and has a U-shaped influence on light pollution and heavy pollution provinces and cities,while it has no significant influence on medium pollution provinces and cities.In addition,the clear green development strategy of the Yangtze River Economic Belt in 2016 effectively enhanced the role of environmental regulation in promoting the industrial green transformation of the Yangtze River Economic Belt.In general,the intensity of environmental regulation in the Yangtze River Economic Belt is low,and the policy effect has not been fully brought into play.To further promote the industrial green transformation in the Yangtze River Economic Belt,we should take the heterogeneity of pollutant discharge as an important reference,formulate targeted environmental regulation policies by classification and region,accelerate the construction of regional consultation mechanism for environmental regulation,and promote the continuous enrichment and dynamic optimization and adjustment of environmental regulation policies.
