数字经济碳减排效应分析——基于生产与消费端的双重路径分析

Analysis of Carbon Emission Reduction Effect of Digital Economy:Based on the Dual Path Analysis of Production and Consumption

基于2013—2019年中国30个省份的面板数据,从市场生产端与消费端构建数字经济碳减排的理论框架及传导机制。研究发现:数字经济能够显著降低碳排放强度,实现碳减排效应,且经过内生性与稳健性检验后结果依然显著。在数字经济的三个子维度中,信息化发展、互联网发展对碳减排都存在显著的促进作用,但数字交易发展的碳减排效应并不显著。数字经济对碳减排的影响存在异质性,数字经济的碳减排效应在东中部、高市场化程度和高创新创业水平的地区更加显著。机制分析结果表明,数字经济能够通过推动生产端的产业结构升级与消费端的消费结构升级来降低碳排放强度。这对实现绿色低碳发展具有重要的参考意义。

Based on the panel data of 30 provinces in China from 2013 to 2019,the theoretical framework and transmission mechanism of the impact of digital economy on carbon emission intensity are constructed from the production and consumption sides.The research finds that:Digital economy can significantly reduce carbon emission intensity and achieve carbon emission reduction effect,and the results are still significant after endogenous and robustness tests.In the sub dimensions of the digital economy,the development of information technology and the internet have significantly promoted carbon emission reduction,but the carbon emission reduction effect of the development of digital trading is not significant.There is heterogeneity in the impact of the digital economy on carbon emission reduction,and the carbon emission reduction effect of the digital economy is more significant in the central and eastern regions,high marketization levels,and high innovation and entrepreneurship levels.The mechanism analysis results indicate that the digital economy can achieve a reduction in carbon emission intensity by promoting the upgrading of industrial structure at the production end and the upgrading of consumption structure at the consumption end.This has important reference significance for achieving green and low-carbon development.
