This paper conducts a theoretical and empirical analysis on the carbon transfer behavior of local governments in China's decentralization system by constructing a spatial econometric model of the carbon transfer paths of local governments in China from 2005 to 2020.The research results show that the aggregation classification of carbon transfer coefficients K-means indicates that the participation of local governments in carbon transfer behavior in China from 2005 to 2020 is consistent with the game inference under the environmental constraints.
