Research on the Impact of the Digital Economy on Regional Carbon Emissions under Environmental Policies

The digital economy contributes to the low-carbon development of regions. Environmental policies affect the choice of green behaviors and promote the achievement of the”dual-carbon” goals. This paper takes environmental policies as the starting point to analyze the influence mechanism between the digital economy and carbon emission reduction under environmental policies. Based on this, fixed effect regression models, multiple mediation models, chain mediation models, and moderation effect models are constructed. Panel data from 30 provinces in China from 2011 to 2021 are selected to empirically analyze the impact of the digital economy on carbon emissions using STATA software. Research has shown that digital economy is capable of remarkably diminishing regional carbon emissions, with environmental effects serving as a crucial intermediary in the relationship between the two; there exists heterogeneity in the influence of the digital economy on regional carbon emissions within the context of diverse environmental policy scenarios. Finally, this article proposes targeted strengthening strategies to expand the transmission pathway of regional carbon reduction.
