Research on the Impact of Urbanization on Carbon Emission and Its Mechanism from the Perspective of Regional Innovation Efficiency
The research construct the mechanism of action among regional innovation efficiency,urbanization and carbon emission,this paper empirically analyzes the impact of urbanization on carbon emission and the indirect role of regional innovation efficiency by OLS method based on the panel data of 30 provinces in China from 2010 to 2020,and the panel threshold model with regional innovation efficiency as the threshold is constructed to empirically test the non-linear impact mechanism of urbanization on carbon emission.The results show that urbanization will still increase carbon emission as a whole,and at the same time,it will also inhibit regional innovation efficiency,leading to insufficient innovation motivation for energy saving and environmental protection industries in the process of urbanization,and the increase of carbon emission.It is found that there is heterogeneity between the impact of urbanization on carbon emission and the indirect effect of regional innovation efficiency.As far as the comprehensive effect is concerned,urbanization in the eastern region can significantly reduce carbon emission,while the role of urbanization in the central region on reducing carbon emission is not significant,while urbanization in the western region will increase carbon emission.The threshold results show that on the basis of controlling other variables,there are double threshold effects of urbanization on carbon emission reduction based on regional innovation efficiency;only when regional innovation efficiency reaches a certain threshold,can urbanization reduce carbon emissions more effectively.
