The Impact Mechanism of Environmental Regulation on Energy Conservation and Emission Reduction in the Construction Industry:A Case Study of Low-Carbon Pilot Policies and Carbon Emission Trading Pilot Policies
Scientifically assessing the effect of environmental regulation on energy conservation and emissions reduction in the construction industry is of great significance to realize the carbon peaking and carbon neutrality goals in China.The low-carbon pilot policy(LCP)and the carbon emissions trading pilot policy(CTP)are important policy tools for addressing climate change and reducing greenhouse gas emissions.This paper empirically examines the energy conservation and emission reduction effects of environmental regulation in the construction industry using a difference-in-difference(DID)model,based on indicators of carbon emission(CE)and green energy efficiency(GEE)in various regions of China from 2005 to 2018.It also explores the spatial spillover effects of environmental regulation on energy conservation in the Chinese construction industry and conducts a series of robustness checks.The results show that China's environmental regulation has significant energy conservation effect on the construction industry,but has no significant emission reduction effect on the construction industry.The LCP has a significant positive spatial spillover effect on the GEE in neighboring areas.The results of heterogeneity analysis show that the significant positive effect of environmental regulation on the GEE of the construction industry is mainly concentrated in the areas with high development level of the construction industry,high proportion of the construction industry,and high carbon emissions of the construction industry.Based on the above findings,it is recommended that,the successful experience of the pilot areas should be extended to other cities;the spatial spillover effect of the pilot policies will be used to promote the sharing of talent and resources in the surrounding areas of the pilot areas;and develop differentiated implementation plans for environmental regulations tailored to the specific characteristics of different pilot regions.
