Based on the data of 13 cities in the Jing-Jin-Ji region from 2009 to 2018, evaluating green efficiency of Water Resources by SBM Model, and analysing this region’s spatial autocorrelation by ESDA method. The results show that the green efficiency of water resources in Jing-Jin-Ji region shows a slow decline in fluctuation, with an average annual efficiency of 45%. Spatial autocorrelation is characterized by low agglomeration around Beijing and Tianjin, and decreases year by year.
