Analysis of Spatiotemporal Differences and Convergence of Agricultural Green Total Factor Productivity in the Yellow River Basin
Based on fully considering the agricultural carbon emissions indicator as an unexpected output indicator in the development of agricultural green transformation,this paper constructs a measurement index system for agricultural green total factor productivity in the Yellow River Basin.Based on the SBM model and convergence model of unexpected output,the spatiotemporal differences in agricultural green total factor productivity in the Yellow River Basin since 2010 are calculated,and its convergence is analyzed.The results indicate that in the time dimension,the green total factor productivity of agriculture in the Yellow River Basin shows an increasing trend year by year;In terms of spatial dimension,the development of agricultural green total factor productivity in various provinces of the Yellow River Basin is not balanced,and the agricultural green total factor productivity in downstream provinces is superior to that in midstream and upstream provinces in order.In terms of convergence,the green total factor productivity of agriculture in various provinces of the Yellow River Basin does not exist α Convergence and β Convergence,that is,there is no"catch-up effect"of provinces with low agricultural green total factor productivity moving towards higher provinces.
