Abstract: In order to revitalize Chinese countryside, it has become an unavoidable trend to develop new management entities of grain scale management in rural China. Based on the rice scale management organization’s questionnaire micro-survey, the DEA-Tobit model and quantitative analysis included subject diversity, factor allocation and management in Jiangsu Province, the paper analyzed the differences and influencing factors of the comprehensive technical efficiency. It was discovered that, the comprehensive production efficiency was in a medium level at the present stage. The efficiency of technology application and scale expansion needed to be improved. The scale management brought about a simultaneous increase in rice input costs，gross income and labor productivity. There were obvious regional differences of production characteristics. The results showed as follows: (1) Compared to the attribute diversity, the scale diversity had the more profound impact on the comprehensive technical efficiency and its decomposable efficiency. The impact of family farms, cooperatives and enterprises on comprehensive production efficiency has increased in turn. The moderate scale management of various entities needs to match their production capacity. Raising the price of rice products will promote the comprehensive technical efficiency of various entities. (2) The capacity of elements allocation and management had a significant positive effect on the comprehensive technical efficiency and its decomposable efficiency. In order to improve the comprehensive technical efficiency, it is critical to enhance the professional skills of labor and stabilize land transfer. (3) Taking other factors into consideration, such as improving the price market, land integration, expanding the new technology by government, and etc., they also had a positive effect on the comprehensive technical efficiency and its decomposable efficiency. Therefore, it is necessary vital to cultivate various agricultural scale operators in China, which will be helpful to establish a modern agricultural management system.
