The transfer of carbon emissions within urban areas caused by the evolution of urban spatial structure may also have a profound impact on economic decarbonization.Using data from prefecture level and above cities in the Yangtze River Delta from 2006 to 2017,this study empirically investigates the eco-nomic decarbonization effect and regulatory mechanism of carbon emission transfer from the center to the periphery of the city.Research has found that:Firstly,the process of carbon emissions transferring from the city center to the periphery has an economic decarbonization effect,especially the decarbonization effect transferring to the semi periphery area is most obvious,and this effect is more pronounced for cities with lower or higher levels of economic decarbonization.Secondly,improving green total fac-tor productivity and accelerating industrial upgrading can strengthen the economic decarbonization effect of carbon emis-sion transfer,and the favorable regulatory effect of green total factor productivity mainly comes from efficiency changes rather than technological progress.Thirdly,the economic decarboniza-tion effect of carbon emission transfer,as well as the favorable regulatory effect of green total factor productivity and industrial upgrading,have heterogeneity in cities in the Yangtze River Del-ta.They mainly exist in second-and third tier cities,coastal cities along the river,and cities with relatively clean industry carbon emission structures.The research conclusion helps to re-veal the relationship between carbon emission transfer and eco-nomic decarbonization from the perspective of spatial structure,and provides policy reference for the government to optimize ur-ban spatial structure in a targeted manner and maximize the eco-nomic decarbonization effect of carbon emission transfer.
