摘要
运用面板三阶段DEA模型对长江经济带农业绿色生产效率进行测度,并在此基础上进行收敛性分析.结果表明,环境因素和随机误差对长江经济带农业绿色生产效率具有显著影响;长江经济带上游、中游和下游的农业绿色生产效率存在明显的空间不均衡现象;2017-2019年长江经济带三大区域省市间农业绿色生产效率差异呈缩小趋势.基于此,为了进一步从总体上提高及从空间上优化长江经济带农业绿色生产效率,提出明确地区环境,因地制宜;把握区域差异,精准施策;打破区域壁垒,协同发展的对策.
Abstract
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.
