Abstract: Under the background of agricultural structure adjustment, improving rice production efficiency is of great significance for ensuring food security in China. Based on the data of main Indica and Japonica rice producing provinces in China from 1999 to 2015, this paper calculated the DEA-Malmquist index of rice production efficiency in each province of China by data envelopment analysis. The Malmqusit index reflecting total factor productivity of rice production was calculated, and the total factor productivity was decomposed into the change of scale efficiency, change of pure technical efficiency and change of technological progress. The results showed that: ① in terms of regional distribution of main rice producing areas， rice industry distribution might be combined with regional advantages. ② Technology progress had played an important role in improving the input-output efficiency of rice production. In promoting rice cultivation, the agricultural sector should pay full attention to the role of technology progress. ③ Developing moderate scale management, improving scale efficiency and rice production efficiency were the main tasks. In the future, the rice industry will still take destocking, green development and scale operation as the major trend.
