Eco-efficiency is related to the dual issues between economy and ecology. It must be ensured that the environmental impact is kept to a minimum while realizing the normal development of social economy. Taking 13 cities in Jiangsu Province as examples, the paper evaluates the efficiency of urban Ecology and environment and its influencing factors of each city in Jiangsu Province from 2009 to 2015 through the super-efficient DEA model and Tobit regression analysis. The research shows that: The eco-efficiency of each city is in the middle and upper level, and the regional differences are obvious. It is the highest in central Jiangsu and the worst in northern Jiangsu; the urbanization rate has a positive impact on the urban efficiency of urban Ecology and environment in Jiangsu, and the industrial structure has an inhibitory effect on the urban efficiency of urban Ecology and environment in Jiangsu. The impact on urban efficiency of urban Ecology and environment is not obvious.
