With the advance of new urbanization, the problems of water shortage and water pollution have become increasingly prominent. A super logarithmic function model is established, and the water use efficiency in Jiangsu Province is calculated by using SFA. By selecting the indices of urbanization of population, social urbanization and industrial urbanization to represent the level of urbanization, the relationship between the use efficiency of water resources and the new urbanization in Jiangsu Province is analyzed based on the STIRPAT model. The conclusions are drawn as follows: (1)The results of water use efficiency of three regions are the highest in the central areas, the lowest in the southern areas and in the middle in the northern area of Jiangsu Province. (2)The urbanization level of population has the greatest impact on water use efficiency in Jiangsu Province. (3)The social urbanization level is negatively correlated with the utilization efficiency of water resources, and the impact of industrial urbanization level on water use efficiency is quite different in various areas.
