Abstract: Based on system theory，this paper puts carbon emission into the study framework of agricultural production efficiency. Firstly，we measured Chinas 30 provincial agricultural production efficiency using three DEA models，and then explored the efficiency differences of each province and three major areas. Four kinds of models of utilizing resource were put forward，and Tobit model was utilized to examine the affecting factors of Chinas agricultural production efficiency. The result revealed that Chinas agricultural production efficiency has been improved in the past，but remained very low，because the pure technology efficiency was low. There were relatively significant differences in the agricultural production efficiency of all provinces and three major areas. The efficiency of eastern is highest，and the west and middle areas’ efficiencies were lower than the average efficiency of whole country. The model of utilizing resource is low economic and low environment in 60% of all provinces，these are mainly from the Midwest of China. It is found that enhancing the ability of resisting the disaster，rural power consumption and R&D expenditure，have remarkable facilitation for improving the agricultural production efficiency. But the level of basic education，industry structure and rural financial supports effects were not significant.
