摘要
文章基于非期望产出的SBM-DEA模型测度了淮河生态经济带25个城市2010-2020年粮食绿色生产效率,并从时间、空间两个维度对其演变特征进行了分析。研究发现:2010-2020年淮河生态经济带粮食绿色生产效率的变化趋势呈现在波动中缓慢上升的趋势,其中19个城市在2020年达到了粮食绿色生产效率有效的水平;同时粮食绿色生产效率与经济发展水平之间没有明显正相关关系,经济欠发达的城市也可以通过规模化生产、优化资源配置、强化农业科技应用等路径优化粮食绿色生产效率。为此,淮河生态经济带应加强高标准农田建设、完善粮食绿色生产机制并促进农业面源污染减量增效,实现淮河生态经济带粮食生产绿色转型。
The article measured the green production efficiency of grain in 25 cities in the Huaihe Ecological Economic Belt from 2010 to 2020 based on the SBM-DEA model of non-expected output,and analyzed its evolution characteristics in two dimensions:time and space.The study found that the trend of grain green production efficiency in the Huaihe Ecological Economic Belt from 2010 to 2020 showed a slow increase in fluctuation,with 19 cities reaching the effective level of grain green production efficiency in 2020;at the same time,there was no obvious positive correlation between grain green production efficiency and economic development level,and cities with less developed economy also The cities with less developed economies can also optimise the green production efficiency of grain through such paths as large-scale production,optimising resource allocation and strengthening the application of agricultural science and technology.In this regard,the Huaihe Ecological Economic Zone should strengthen the construction of high-standard farmland,improve the mechanism of green grain production and promote the reduction and increase of agricultural surface source pollution,so as to achieve a green transformation of grain production in the Huaihe Ecological Economic Zone.
