Evaluation of Grain Production Efficiency in the Main Grain Producing Areas in China Based on a Three Stage DEA Model

초록

There is a great theoretical and practical significance attached to the reasonable evaluation of the efficiency of grain production, recognition of the current situation of grain production, and exploration of effective ways to improve grain production efficiency against the background of the limited cultivable area and rapid progress of urbanization. Based on the data of 13 main grain-producing areas in China from 2007 to 2019, this study adopted the method of three-stage data envelopment analysis (DEA) to analyze agricultural production efficiency. The results revealed that exogenous environmental variables had a marked impact on grain production efficiency. The three-stage DEA model can reflect the level of food production efficiency in the main grain-producing areas more accurately, so the focus should be on formulating efficiency improvement strategies according to the local realities.
