Abstract
This study analyzes the evolution of China's green technology innovation cooperation network from 2011 to 2020, utilizing green patent application data. Employing a Spatial Durbin Model (SDM), we scrutinized the network's influence on urban carbon emissions, utilizing panel data encompassing 323 city nodes. Results show network expansion and a shift in central nodes from eastern coastal areas to interior cities, with Beijing, Shenzhen, Nanjing, and Shanghai consistently acting as key innovation hubs. A core-periphery structure emerged, clustering cities into high- and low-cooperation clusters. Core cities, particularly Beijing, which gain informational advantages by bridging non-overlapping nodes and exhibit distinct characteristics in terms of the structural hole indexes, reflecting their multifaceted roles within the network. SDM analysis indicates that the green technology innovation cooperation network has a significant positive impact on urban carbon reduction efforts. Specifically, degree centrality, closeness centrality, effective size, efficiency, and hierarchy of node cities exhibit a negative correlation with carbon emissions, suggesting that higher centrality and efficiency within the network correlate with lower emissions. Conversely, betweenness centrality and constraint have a positive impact on emissions, indicating that cities that act as bridges in the network may paradoxically contribute to higher emissions. Moreover, the network's influence on carbon emissions is nuanced across different green technology sectors. Cooperation in areas such as waste management, alternative energy production, energy conservation, agriculture and forestry, and transportation is found to have a more substantial impact on carbon reduction than cooperation in nuclear power, and administrative, regulatory, and design fields.
