环境规制对二氧化硫排放的门槛效应

Threshold Effect of Environmental Regulations on Sulfur Dioxide Emissions

研究选取2004-2017年省级面板数据,以能源结构及产业结构为门槛变量,探究环境规制与二氧化硫排放之间的门槛效应。实证结果显示,能源结构和产业结构在环境规制与二氧化硫排放关系中存在双门槛效应,两者水平的改善均促进了环境规制对二氧化硫排放的抑制作用。城镇化水平、对外开放水平、经济水平等是影响二氧化硫排放的重要因素。为提升经济绿色发展,要对能源和产业结构进行优化调整,并加大对新能源技术的开发利用。

Based on the provincial panel data from 2004 to 2017,this paper takes energy structure and industrial structure as threshold variables to explore the threshold effect between environmental regulation and sulfur dioxide emissions. The empirical results show that, energy structure and industrial structure have double threshold effect in the relationship between environmental regulation and sulfur dioxide emissions, and the improvement of both levels promotes the inhibitory effect of environmental regulation on sulfur dioxide emissions. The level of urbanization, the level of opening to the outside world and the level of economy are the important factors that affect the emission of sulfur dioxide. In order to promote green economic development,we should optimize and adjust the energy and industrial structure,and increase the development and utilization of new energy technologies.
