Measurement and convergence of agricultural green production efficiency in the Yangtze River Economic Belt under carbon emission constraints
Agricultural green production efficiency in the Yangtze River Economic Belt was measured with the panel three-stage DEA model,and convergence analysis was made on this basis.The results showed that environmental factors and random errors had signifi-cant effects on agricultural green production efficiency in the Yangtze River Economic Belt.The agricultural green production efficien-cy in the upper,middle and lower reaches of the Yangtze River economic belt had obvious spatial imbalance phenomenon.The differ-ence of agricultural green production efficiency among provinces(cities)in the three regions of the Yangtze River Economic Belt showed a decreasing trend.Based on this,in order to further improve and spatially optimize the agricultural green production efficien-cy in the Yangtze River Economic Belt,the following suggestions were proposed,such as clarifying the regional environment and adapting to local conditions;grasping regional differences and implementing precise policies;breaking down the regional barrier and promoting coordinated development.
