中文摘要:

      本文立足长江经济带环境规制与工业绿色转型实践，分析了双重市场激励型规制影响工业绿色转型的内在机理，并利用2002—2017年长江经济带11个省市面板数据进行实证分析。研究发现：①双重市场激励型规制均显著地促进了工业绿色转型，但是费用型规制的促进效应存在递减特征。②异质性检验表明，费用型规制对长江中下游地区、人均GDP较高省份以及第二产业占比较高省份的工业绿色转型促进效应更为明显。③中介效应模型检验结果显示，提高末端治理技术是工业绿色转型的重要渠道。④研究还发现，费用型规制对高能耗行业、二氧化硫排放量和粉尘排放量具有显著的抑制效应，投资型规制对废水排放量和固体废物排放量的抑制效应更明显。⑤随着工业绿色转型程度的不断提升，双重市场激励型规制对工业绿色转型的边际效应先后呈现“ L”形骤降特征。因此不断优化与创新环境规制手段，才是持续推进工业绿色转型的关键所在。

英文摘要:

      Based on the practice of environmental regulation and industrial green transformation in the Yangtze River economic belt, this paper analyzed the mechanism of the impact of the cost and investment environmental regulation on industrial green transformation, and empirically tested the hypothesis by using the panel data of 11 provinces in the Yangtze River economic belt from 2002 to 2017. The empirical results showed that the two environmental regulations significantly promoted the green transformation of industry, but the effect of cost regulation was decreasing. Heterogeneity test showed that cost regulation played an obvious role in promoting industrial green transformation in the middle and lower reaches, provinces with high per GDP and provinces with high proportion of secondary industry. The result of intermediary effect test showed that improving the terminal governance technology was an important channel. It was also found that cost regulation had a significant inhibitory effect on high-energy consumption industries, sulfur dioxide emissions and dust emissions, and investment regulation had a more obvious inhibitory effect on wastewater emissions and solid emissions. Moreover, with the continuous improvement of the degree of industrial green transformation, the marginal effects of the two environmental regulations on industrial green transformation showed the characteristics of “L” sharp decline. Therefore, this paper believed that constantly optimizing and innovating environmental regulation is vital to continuously promoting industrial green transformation.
