Study on the Impact of Carbon Emission Trading System on Energy Efficiency
Based on the provincial panel data from 2007 to 2019,the influence of China's carbon emission trading system on energy efficiency was investigated by using PSM and DID.The result shows that the carbon emission trading system has significantly im-proved energy utilization efficiency,mainly by promoting marketization and reducing the resource curse.The heterogeneity analysis shows that compared with the eastern and central regions,the carbon emission trading system improves energy efficiency in the western region more significantly.In the regions with high green innovation efficiency and high environmental protection expenditure effect,the carbon emission trading system plays a more prominent role in promoting energy use efficiency.
