多中心空间结构对城市碳中和的影响效应研究OACHSSCD

Against the dual backdrop of green and low-carbon transition and urbanization shifting from a period of rapid growth to stable development,the polycentric spatial structure,as a key form promoting sustainable development,has made its impact on carbon neutrality a critical issue.Using panel data from 281 cities in China from 2011 to 2023,this study systematically examines the effect of polycentric spatial structure on carbon neutrality.The findings are as below.First,the impact of polycentric spatial structure on carbon neutrality exhibits a U-shaped relationship,initially inhibiting and later promoting carbon neutrality.Second,technological innovation and land use conflicts play mediating roles in the relationship between polycentric spatial structure and carbon neutrality.Third,the impact of polycentric spatial structure on carbon neutrality is more pronounced in cities with low river density,non-coastal cities,and small to medium-sized cities.Therefore,it is essential to promote polycentric spatial planning in stages,strengthen the synergistic integration of technological innovation and land use,and formulate tailored policies based on local conditions to facilitate the coordinated realization of spatial structure optimization and carbon neutrality goals.
