基于DEA-Malmquist模型的中国小麦生产效率分析

Analysis of wheat production efficiency in China based on DEA-Malmquist model

采用三阶段DEA模型对中国13个小麦(Triticum aestivum L.)主产区的生产效率进行静态分析,并运用三阶段DEA-Malmquist模型,以2008—2019年面板数据,从综合效率变动指数、技术效率变动指数以及技术进步变动指数3个方面进行动态研究。研究发现,中国小麦主产区普遍存在管理水平低下、创新科技水平应用程度较低以及小麦种植规模未达到最优等问题,在未来发展上还有很大的提升空间。

The three-stage DEA model is used to statically analyze the wheat production efficiency of 13 main wheat producing areas in China,and the three-stage DEA-Malmquist model is used to conduct dynamic research from three aspects of comprehensive efficiency change index,technical efficiency change index and technological progress change index based on panel data from 2008 to 2019.It is found that there are many problems in China’s main wheat producing areas,such as low management level,low application level of innovation and science and technology,and suboptimal wheat planting scale.There is still a lot of room for improvement in the future development.
