Abstract：Based on the social network analysis method,the panel data of 277 cities in China from 2010 to 2022 are selected as research samples,and the urban innovation network is constructed by collaborative patent data.The overall characteristics and individual characteristics of the network are described,and the impact and mechanism of urban innovation network characteristics on carbon emissions are empirically analyzed.The results show that:① from 2010 to 2022,the overall structure of China's urban innovation network is stable,the direct connections are steadily increasing.Beijing,Shanghai,Suzhou,Hangzhou and other eastern developed cities occupy the core position of innovation network,and gradually expand their influence over time.② the degree of centrality and structural holes in the urban innovation network will exacerbate carbon emissions,and the impact has significant regional heterogeneity.Compared with the central and western regions,the degree centrality and structural holes of eastern cities have more significant impacts on carbon emissions.③ urban innovation will play a partial mediating role in the promotion of carbon emission by degree centrality and structural hole.Environmental regulation can negatively regulate the promoting effect of degree centrality and structural holes on carbon emission.
