In the context of ensuring food security,based on the DEA-Malmquist index method,the dynamic input-output efficiency of rice in 13 prefecture level cities and 1 autonomous prefecture of Hu-nan Province was measured,and Hunan Province was divided into four regions:the Changsha-Zhu-zhou-Xiangtan urban agglomeration,the southern Hunan region,the western Hunan region,and the Dongting Lake region for comparative analysis.The empirical analysis results show that:firstly,due to the improvement of technology,total factor productivity is on the rise;secondly,there are significant differences in total factor productivity among different prefecture level cities and autonomous prefectures;Thirdly,total factor productivity shows a decreasing trend in the Dongting Lake region,the Changsha-Zhuzhou-Xiangtan urban agglomeration,the southern Hunan region,and the western Hunan region.Based on this,targeted suggestions are proposed to implement policies from three aspects:increasing scientific research investment to improve technology,introducing policy dividends by the government to solve practical difficulties,and promoting economic development to improve the planting environment.
