数字经济碳减排的溢出效应及作用机制研究OACHSSCD

In order to explore the important role played by digital economy in realizing the goal of"double carbon",this paper selects the panel data of 30 provinces in China from 2010 to 2021 to build a spatial dubin model to empirically test the external spillover effect of digital economy on carbon emis-sions,and discusses the role of heterogeneous green technology innovation in it.The results show that the development of the digital economy can effectively inhibit carbon emissions,and there is a signifi-cant spatial spillover effect in this process,and the indirect spillover effect of the development of the digital economy on low-carbon development is stronger than the direct effect;that in the relationship between the development of the digital economy and carbon emissions,green technology innovation plays an intermediary role,and the roles of inventive green technology innovation and practical green technology innovation in the process of affecting carbon emissions in the digital economy are different,and the former accounts for a larger proportion of the intermediary effect;and that with the increasing degree of government intervention,the inhibitory effect of the digital economy on carbon emissions has also been increasing.This study provides new documentary evidence and subdivision transmission mechanism for the causal relationship between digital economy and carbon emissions.
