数字经济空间关联网络的碳减排效应OACHSSCD

The formation of spatial correlation networks in the digital economy has reshaped the material foundation and technical para-digm of regional economic linkages.Based on the carbon reduction effect hypothesis and influencing mechanism of such networks,this study employs panel data of 263 prefecture-level cities in China from 2010 to 2023.Using a revised gravity model and social network a-nalysis,this paper verifies the research hypotheses and interprets the empirical results.The findings indicate that the overall connectiv-ity of digital economy spatial correlation networks has steadily improved over the sample period,presenting a significant carbon emission reduction effect.This effect can be effectively enhanced by reducing energy consumption intensity,facilitating digital industry agglom-eration,and promoting green technological innovation.Spatially,the carbon reduction effect exhibits evident regional heterogeneity and is more pronounced in eastern and central regions with higher economic development,high-carbon resource-based cities,and policy-supported digital economy pilot areas.
