Grain production is vital to the national economy and people's livelihood, and improving grain production efficiency is of great significance to the sustainable development of China's economy and society. From the perspective of financial support, using the DEA global Malmquist productivity index model and based on the data of 13 main grain producing areas in China from 2001 to 2017, this paper discusses the evolution characteristics and regional distribution differences of the total factor productivity index of grain production in China's main grain producing areas. The results show that from 2001 to 2017, the total factor productivity index of grain production in China's main grain producing areas showed an overall fluctuation trend of gradual decline, with an average annual decline of 7.3%. From the perspective of spatial analysis, the grain production efficiency in China's main grain producing areas is characterized by uneven spatial development, which is generally manifested as the decreasing trend from the central region to the eastern and western regions. Meanwhile, it can be seen from the decomposition index that the change of total factor productivity of grain production in China's main grain producing areas mainly depends on the change of technical efficiency.
粮食生产对国民经济和民生至关重要，提高粮食生产效率对中国经济和社会的可持续发展具有重要意义。从金融支持的角度来看，利用 DEA 全局 Malmquist 生产率指数模型，基于 2001 年至 2017 年中国 13 个主要粮食产区的数据，本文探讨了中国主要粮食产区粮食生产全要素生产率指数的演变特征和区域分布差异。结果表明，2001 年至 2017 年，中国主要粮食产区粮食生产的全要素生产率指数整体呈现出逐渐下降的波动趋势，年均下降 7.3%。从空间分析的角度来看，中国主要粮食产区的粮食生产效率呈现出空间发展不均衡的特点，总体表现为从中部地区向东部和西部地区递减的趋势。同时，从分解指数可以看出，中国主要粮食产区粮食生产全要素生产率的变化主要取决于技术效率的变化。
