Study on the spatial and temporal differentiation of agricultural green total factor productivity:Taking the Yangtze River Economic Belt and the Yellow River Basin as examples
Based on the SBM-Malmquist index method,the agricultural green total factor productivity and its decomposition indexes in the Yangtze River Economic Belt and the Yellow River Basin from 2011 to 2021 was measured and the ESDA model was used to ana-lyze its spatial distribution characteristics.The results showed that the agricultural green total factor productivity of the Yangtze River Economic Belt and the Yellow River Basin showed an overall upward trend,and the regional differences gradually narrowed.The agri-cultural green total factor productivity of the eastern provinces grew faster.There were different degrees of slack in agricultural input and output indicators,especially in labor input and mechanical power input.Insufficient output was not the main reason for low agricul-tural green total factor productivity of some provinces.Spatial correlation was not significant,and there was no obvious agglomeration or dispersion pattern.Although the center of gravity had migrated locally,it was generally relatively stable.The focus of agricultural green total factor productivity in the Yellow River Basin had gradually shifted from the middle reaches to the upper and lower reaches,and the focus of agricultural green total factor productivity in the Yangtze River Economic Belt had gradually shifted downstream.
