Promoting the reduction of carbon emissions through the development of the digital economy is the key to addressing prominent problem of resource and environmental constraints and achieving high-quality economic development.Using panel data from prefecture level and above cities nationwide,systematically verify the impact and mechanism of the digital economy on carbon emissions from a spatial spillover perspective.The results indicate that the digital economy and its spatial spillover effects have significantly reduced carbon emissions in the local and adjacent regions,helping to form a coordinated development pattern of digital economy promoting carbon emission reduction among regions.Moreover,the above conclusion still holds true after a series of robustness tests.Heterogeneity testing shows that the digital economy can significantly reduce carbon emissions in resource-based cities and neighboring areas,while it is not significant in reducing carbon emissions in non-resource based cities.The transmission mechanism test shows that,in addition to direct empowerment,the digital economy can reduce local carbon emissions by promoting technological progress and industrial structure upgrading.The spatial spillover effect of the digital economy can be achieved through the guidance of technological progress and industrial structure upgrading at the current stage.Based on this,we should actively strengthen regional cooperation,promote quality and efficiency improvement,and broaden the implementation path to help the digital economy reduce carbon emissions and achieve high-quality development.
