Evaluation of Grain Security in China’s Major Grain-Producing Areas Based on the Entropy Weight TOPSIS Method

초록

The major grain-producing areas are the key to ensuring China's grain security. This paper approached the issue from major grain-producing areas, and used the entropy weight TOPSIS method to comprehensively evaluate the grain security of China from 2010 to 2019 from the three dimensions of supply capacity, grain availability, and grain sustainability. The results show that, from the time dimension, the grain security levels of Anhui, Hebei, Heilongjiang, Inner Mongolia, and Sichuan provinces fluctuated upwards; the grain security levels of Henan and Hubei were relatively stable; the other six provinces showed a volatility decline. From the perspective of space, except for Sichuan province, the grain security status of the other provinces was generally at the upper-middle level. In the past ten years, Hunan province boasted the highest level of grain security, whose average output ranks first while Sichuan ranks last in grain production. Finally, the relevant policy recommendations from ensuring grain production capacity and stabilizing grain output, strengthening overall planning and deployment to ensure grain availability, and growing grain scientifically to ensure the sustainability of grain production were proposed to ensure grain security.
