The impact of urban sprawl on green total factor productivity: A spatial econometric analysis in China

The rapid expansion of Chinese cities has led to serious urban productivity and eco-environment changes, therefore attracted considerable international academic attention. main objective this study is investigate the theoretical mechanisms practical effects sprawl on green total factor (GTFP), in order provide a reference for optimizing spatial layout promoting high-quality economic development. Realistic land area population characteristics are extracted using DMSP/OLS NPP/VIIRS nighttime lighting data, LandScan global dynamics statistics measure index. GTFP measured super-SBM model that considers undesirable output. Based panel data from 2006 2020, Durbin was constructed carry out empirical analysis. results show that, overall, China detrimental its own GTFP, while contributing neighboring cities. impacts vary markedly across different sizes regions.
