Research on the Influence of Agricultural PPP on Agricultural Green Total Factor Productivity——Based on theEmpirical Analysis of the Yangtze River Economic Belt
Improving the green total factor productivity of agriculture is the key embodiment of high-quality agri-cultural development,and the cooperation mode between government and social capital(PPP mode)is an effective mode of agricultural investment and financing.Using the SBM function of ML index method respectively,this pa-per measured the 2016-2020 Yangtze River economic belt agricultural green total factor productivity level and decomposition(technical efficiency and technological progress),combined with the panel fixed regression model of the PPP model of agricultural rural field of the Yangtze River economic belt agricultural green total factor pro-ductivity and the internal mechanism.The results show that agricultural PPP significantly improves the green total factor productivity of agriculture in the Yangtze River Economic Belt at 5％,and there is regional heterogeneity in the influence of the upstream and downstream regions,and the effect of the downstream regions is greater.This conclusion is still true after passing the robustness test.In addition,industrial structure,urbanization,technology level and land scale are significantly positively correlated with agricultural green total factor productivity.At the end,this paper puts forward corresponding suggestions to improve the green total factor productivity of agricul-ture in the Yangtze River Economic Belt,and then realize the strategic goal of high-quality agricultural develop-ment.
