The spatial association network and driving factors of land use carbon emission efficiency in China:An investigation in the National Major Strategic Regions
[Objective]Exploring the spatial association network structure of land use carbon emis-sion efficiency can provide scientific basis and practical reference for promoting the green and low-carbon transformation of the National Major Strategic Regions in China and achieving synergistic advancement of the dual-carbon targets.[Methods]This study took 199 cities in the National Ma-jor Strategic Regions as the research objects,and adopted the super-efficiency EBM model,social network analysis,and Geodetector to investigate the characteristics of the spatial association net-work structure of land use carbon emission efficiency and its driving factors from 2005 to 2020.[Results](1)During the study period,the land use carbon emission efficiency in the National Ma-jor Strategic Regions showed a trend of initial decrease followed by an increase.However,there were obvious differences among regions,Guangdong-Hong Kong-Macao Greater Bay Area have the highest average value of land use carbon emission efficiency,followed by the Yangtze River Delta region,the Yangtze River Economic Belt,Beijing-Tianjin-Hebei region and the Yellow River Basin region.(2)Over time,the structure of the overall networks of land use carbon emission effi-ciency in the National Major Strategic Regions has generally evolved towards densification,diver-sification and robustness.The structure of the individual networks was characterized by a signifi-cantly larger number of net spillover cities than net detractor and cooperator cities,reflecting a"core-periphery"structural characteristic.(3)There was heterogeneity in the influence of different driving factors on the spatial linkage strength of land use carbon emission efficiency in the National Major Strategic Regions.Among them,economic development,resource endowment,government regulation,and policy guidance emerges as a dominant role,and the interactive combination of driving factors showed a dual-factor enhancement effect.[Conclusion]The National Major Strate-gic Regions should focus on the spatial association network structure of land use carbon emiss effi-ciency,and promote the orderly flow of factors and the rational allocation of resources among re-gions.It is necessary to propose differentiated land use low-carbon transformation paths tailored to local conditions to promote synergistic regional emission reductions and coordinated development.
