Abstract

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 andstrengthening 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.

Keywords
