数字经济通过能源利用效率对碳排放的影响——基于市级面板数据的实证分析

The Impact of Digital Economy on Carbon Emissions through Energy Efficiency—An Empirical Analysis Based on Municipal Panel Data

摘要: 本文以黑龙江、吉林、辽宁三省下辖的36个地级市、自治州和地区2010~2019年的面板数据为研究对象，构建测度指标体系衡量各市的数字经济的年度发展水平，以能源利用效率为路径，进行基准回归、中介效应和调节效应分析，探究数字经济的发展对碳排放的影响。根据研究结果本文得出结论：(1) 数字经济的发展对碳排放有抑制作用。(2) 数字经济通过提升能源的生产转化和消费效率抑制碳排放。(3) 数字经济通过能源生产和消费结构优化从而抑制碳排放。

Abstract: This article uses panel data from 36 prefecture level cities, autonomous prefectures, and regions under the jurisdiction of Heilongjiang, Jilin, and Liaoning provinces from 2010 to 2019 as samples to construct an indicator system to calculate the digital economy development index of each city. Through benchmark regression, mediation effect model, and moderation effect model, the impact of digital economy on carbon emissions through energy utilization efficiency is analyzed. Based on the research results, it can be concluded that: (1) Digital economy deployment has suppressive effects on carbon emissions. (2) The digital economy suppresses carbon emissions through the mediating effects of improving energy production conversion efficiency and reducing energy consumption intensity. (3) The digital economy optimizes the energy production structure and suppresses carbon emissions.
