数字经济对我国碳排放的影响研究

基于2013-2020年的30个省份数据构建面板数据模型，从碳排放总量和碳排放强度两个视角研究数字经济发展对区域碳排放的影响。研究发现：数字经济的发展有效地降低了人均碳排放量、碳排放增量与碳排放增速，数字经济与碳排放强度之间存在倒“U”形关系，数字经济与碳排放强度、边际碳排放强度的关系呈现区域性特征，在省域层面数字经济对边际碳排放强度的影响不存在明显的空间效应，数字经济对碳排放增长率的影响存在基于产业结构优化、人口集聚、城镇化的遮掩效应。

Research on the Impact of Digital Economy on Carbon Emissions in China

Based on the data of 30 provinces from 2013 to 2020, this paper constructs panel data models to study the impact of digital economy development on regional carbon emissions from the perspectives of total carbon emissions and carbon emission intensity. The findings are as follows: the development of digital economy can effectively reduce per capita carbon emissions, carbon emissions increment and carbon emissions growth rate; there is an inverted U-shaped relationship between digital economy and carbon intensity; the relationship between digital economy and carbon emission intensity and marginal carbon emission intensity presents regional characteristics; at the provincial level, digital economy has no obvious spatial effect on marginal carbon emission intensity; the influence of digital economy on carbon emission growth rate is based on the suppressing effect of industrial structure optimization, population agglomeration and urbanization.
