Structural characteristics and evolutionary mechanism of spatial correlation network of carbon emissions in the Yangtze River Delta
Based on the data of 41 cities in the Yangtze River Delta(YRD),the gravity model is used to construct a spatial correlation network of carbon emissions.Social network analysis methods and the Temporal Exponential Random Graph Model(TERGM)are used to identify the structural characteristics and evolution mechanisms of the network.The findings are as follows:(1)The spatial association of carbon emissions in the YRD is becoming increasingly close,with enhanced network complexity and stability,yet the relatively low network density indicates significant potential for future cooperation.(2)Cities in Anhui and Northern Jiangsu constitute the net overflow plate,while Shanghai and cities in Southern Jiangsu form the net benefit plate.The interprovincial border areas and cities within Zhejiang constitute the broker plate.There are multiple bidirectional spillover channels among these plates,with evidence of"club"clustering within each plate.(3)The"broker"connectivity structure and the dominant connectivity structure of core nodes have played a crucial role in the evolution of the spatial correlation network of carbon emissions in the study area.The network evolution has transitioned from a chain-like structure driven development to a closed-loop structure driven development.However,the non-cooperative game strategy of prioritizing self-interest among cities has diminished the potential for cooperative emission reduction.(4)The endogenous structures of reciprocity,connectivity,and circularity contribute to the formation of the spatial correlation network of carbon emissions in the YRD region.The abilities of actors,such as external openness,industrial structure,green technological innovation,digital economic development,energy intensity,environmental regulations,and carbon sink pressure,require the mechanisms of resource endowment differentiation,market regulation,government macro-control,and technological innovation promotion to facilitate network evolution.The evolution of this network exhibits characteristics of both path dependence and path creation.
