Temporal-Spatial Evolution and Driving Factors of the Green Total Factor Productivity of China’s Central Plains Urban Agglomeration

As China’s largest urban agglomeration with rapid growth of economy and population, the development Central Plains Urban Agglomeration (CPUA) has been severely restricted by environmental problems. Thus, green performance CPUA is worth studying. This study used panel data 29 cities in from 2003 to 2018 based on Slacks-based Measure Global Malmquist–Luenberger index measure total factor productivity (GTFP) its decomposition each city. A spatial econometric model was developed explore factors affecting GTFP CPUA. The results show that had an upward trend 2003–2018, but level still low. There were significant spillover effect among different measurement technological progress, industrial structure solid waste regulationhave a positive GTFP. The, fiscal expenditure, informatization also have impacts In future, local government should provide technical financial support for industries CPUA, accelerate construction protection infrastructures.
