Abstract Based on two spatial association indices, namely Global Morans I and Getis-Ord, and coordinated development degree function, the spatial pattern and regional evolution of water resource efficiency of oasis cities in Xinjiang in 1990, 1995, 2000 and 2005 were discussed. In addition, we analyzed the coordination degree between water resource efficiency of oasis cities and urbanization level in Xinjiang. Results are as follows: (1) Water resource benefit of oasis cities in Xinjiang presented a spatial aggregated distribution around the north slope of the Tianshan Mountains. (2) The evolution of regional water resource efficiency showed different evolution process. (3) The evolution of spatial pattern of coordination development degree between water resource benefit and urbanization level was relatively stable. In detail, the regions with high coordination development degree showed an expansion trend, and the regions with low coordination development degree showed a converged trend. The coordination between water resource benefit and urbanization level can be divided into five types: synchronization coordination, lagging urbanization, lagging water resource benefit, gradually fitting, and low level coordination.
