Abstract: Undesired output SBM model, correlation analysis model and center of gravity model were used to evaluate the agricultural ecological efficiency of Chongqing City from 2010 to 2018, the correlation of the spatial distribution of agricultural ecological efficiency in Chongqing in each year, and the evolution of the gravity center of agricultural ecological efficiency. The results showed that, from 2010 to 2018, the average value of agricultural ecological efficiency in Chongqing City had fluctuated upward, and the spatial distribution correlation of agricultural ecological efficiency had changed from a negative correlation to a positive correlation. The shift of the gravity center of agricultural ecological efficiency presented a spiral shape and was scattered in the Changshou District of Chongqing City.

Key words: agricultural ecological efficiency, undesired output SBM model, center of gravity model, correlation analysis, Chongqing City
