| Abstract | Global warming is a great challenge faced by all mankind. The continued increase in greenhouse gas emissions will have a negative impact on agricultural production, socio-economic activities and human life, and ultimately hinder the process of achieving global sustainable development. This study attempts to introduce the variable of digital economy development into the research framework of carbon emission impact factor theory to systematically examine the effect of digital economy development on urban carbon emissions. This study was conducted to investigate the spatial effects of the digital economy on urban carbon emissions. Based on the panel data of 286 cities from 2011 to 2017, this study analyzes the impact of digital economy development on urban carbon emissions using the spatial Durbin model and the spatial DID model. The main conclusions are as follows: (1) There is spatial heterogeneity in the development pattern of digital economy, and the development pattern changes from "multi-point" sporadic distribution to "cluster" agglomeration, but the gap between the development levels of cities has not been narrowed, and the Yangtze River Delta becomes an important digital economy agglomeration area. (2) The digital economy has a significant negative effect on urban carbon emissions, and the findings are robust to the introduction of the exogenous policy shock of "smart cities". Moreover, there is spatial heterogeneity in this effect, with the negative effect of digital economy on carbon emissions being stronger in the eastern region, and the influence of digital economy is stronger in regions located within urban agglomerations. (3) In order to investigate the spatial decay characteristics of the spillover effect of the digital economy on urban carbon emissions, the spillover effect analysis of the multi-distance economic circle is carried out, and it is found that the spillover effect of the digital economy on carbon emissions peaks at 1100 km. (4) The coverage of digital infrastructure does not have a significant negative effect on carbon emissions in the region, while digital industry development, digital innovation capacity and digital inclusive finance all have a significant negative effect on carbon emissions in the region and neighboring areas. This study adds to the lack of research on the digital economy and carbon emissions, and provides some theoretical reference for the study of the environmental improvement effects of the digital economy. © 2022, Science Press.
