Analysis of the Impact of Digital Economy on Carbon Emission Intensity and Its Spatial Spillover Effects
Empirical evidence for achieving China's dual carbon targets can be provided by examining the impact of the digital economy on carbon emission intensity.This paper uses the comprehensive evaluation method to calculate and analyze the level of digital economy development in China's provinces from 2012 to 2021,and further constructs a spatial Durbin model to explore the impact of digital economy development on carbon emission intensity and its spatial spillover effects.The results show that from 2012 to 2021,the level of digital economy development in China has been constantly improving,but there are still significant regional differences,with the level of digital economy development in the eastern region relatively higher,followed by the central region,and the lowest level in the western region.The development of the digital economy has a significant impact on carbon emission reduction,and the spillover effect on carbon emission reduction in the region is significant,but the spillover effect on carbon emission reduction in neighboring regions is not significant.Among the controlled variables,the spillover effect of energy consumption intensity on carbon emission intensity is very significant both in the region and in the neighboring regions.The direct spillover effects and the total effects of energy consumption structure and foreign trade dependence are significant,as are the indirect spillover effects of the level of technological innovation and environmental regulation.Based on the empirical results,it is recommended to actively develop the digital economy,activate the vitality of the development of the digital economy,and promote the digital transformation of high-energy-consuming and high-polluting industries,so as to achieve a win-win situation for carbon emission reduction and high-quality economic development.
