Abstract: As a kind of green shared growth, inclusive green growth is an important way to promote common prosperity for all people. Based on the panel data of prefecture level cities from 2008 to 2020, and taking the "National Smart City" pilot policy as the exogenous impact of urban digital economy development, this paper discusses the impact of digital economy development on urban inclusive green growth. The results show that the development of digital economy has significantly promoted the improvement of urban inclusive green growth, and this conclusion is still valid after a series of robustness tests. From the perspective of transmission mechanism, the development of digital economy has significantly promoted the level of inclusive green growth in cities through resource allocation effects and technological innovation effects. From the perspective of spatial effects, the development of digital economy can significantly promote the improvement of inclusive green growth levels in neighboring cities. From the perspective of heterogeneity effects, there are differences in the promotion effect of digital economy development on the level of inclusive green growth in cities with different characteristics, including economic development, fiscal decentralization, and urban size.

Key words: development of digital economy, inclusive green growth, smart city, double difference model
