摘　　要：数字经济作为推动经济高质量发展的重要抓手,能否有效推动区域碳减排备受关注。本文基于2015~2021年的省级面板数据,对我国数字经济发展水平与区域碳排放量之间的关系进行实证检验,并构建了中介效应模型,从政府、企业和个人三个层面分析了数字经济影响区域碳排放量的内在机理。研究发现:现阶段数字经济的发展对区域碳排放量起到抑制作用,两者在长期中呈现“U”型的非线性关系,该结论通过了一系列稳健性检验。机制分析表明,数字经济通过增加财政教育支出、促进产业结构升级、推动技术创新产出和提高公众环境污染关注度这四条路径降低区域碳排放量。异质性分析表明,在高政府环保投资支出、低政府财政教育支出、高产业结构升级程度、高全要素生产率、高公众环境污染关注度的地区,数字经济能够发挥更为显著的碳减排效应。本文从多个视角揭示了数字经济赋能区域碳减排的内在机理,研究结论可为按期实现“双碳”目标提供政策参考。As an important starting point for promoting high-quality development,whether digital economy can effectively promote regional carbon emission reduction has attracted much attention.Based on the provincial panel data from 2015 to 2021,this paper empirically tests the relationship between the development level of China’s digital economy and regional carbon emissions,and constructs an intermediary effect model to analyze the internal mechanism of the impact of digital economy on regional carbon emissions from three levels:government,enterprise and individual.The results show that,in the short term,the development of digital economy can inhibit regional carbon emis-sions.In the long run,the two show a U-shaped nonlinear relationship.The intermediary effect shows that the digital economy reduces regional carbon emissions by increasing education ex-penditure,promoting industrial structure upgrading,promoting technological innovation output and increasing public concern about environmental pollution.Heterogeneity analysis shows that the carbon emission reduction effect of digital economy is more significant in regions with high gov-ernment environmental protection investment expenditure,low government financial education expenditure,high industrial structure upgrading degree,high total factor productivity,and high public environmental pollution concern.This paper reveals the internal mechanism of regional car-bon emission reduction enabled by digital economy from multiple perspectives,and the research conclusions have important reference significance for deepening the green development strategy of realizing the“dual carbon”goal on time.
