Abstract
- This article is based on the statistical yearbook data of 30 provinces, municipalities and autonomous regions in China (excluding Hong Kong, Macao, Taiwan, and Tibet Autonomous Region) from 2000 to 2017, a total of 18 years of statistical yearbook data was used to conduct in-depth research on the reduction of CO<subscript>2</subscript> emissions from the development of new energy in the region. First, it is proposed that the regional new energy development has a significant negative effect on CO<subscript>2</subscript> emissions. Meanwhile, this impact has a significant time lag effect, and the development of new energy cannot be quickly and effectively applied in the short term to replace traditional fossil energy in the dynamic model. Therefore, there is a significant positive impact in the short term, but the significant negative effect of new energy development on CO<subscript>2</subscript> emission can be shown in the long run. Secondly, the new energy development has a significant non-linear impact on CO<subscript>2</subscript> emissions, showing an inverted U-shaped relationship, which confirms the existence of the Environmental Kuznets Curve (EKC) of CO<subscript>2</subscript> emissions based on new energy development. Finally, in order to alleviate the continuous impact of national economic development on CO<subscript>2</subscript> emissions, the DID model is used to prove that the level of technological innovation has a significant moderating effect on the CO<subscript>2</subscript> emission reduction effect of new energy development, which confirms theoretically the importance of technological innovation in accelerating new energy substitution and improving energy efficiency.
