Abstract Based on the panel data of 31 provinces in China from 2003 to 2017, on the basis of measuring the utilization efficiency of urban land and water resources, this paper uses the Coupling Coordination Model to analyze the coordination, contradiction and the spatial-temporal differentiation characteristics of the two resources utilization efficiency. And the Moran index model is also used to analyze the spatial correlation and spatial agglomeration characteristics of coupling coordination degree. There are following findings: (1) The comprehensive utilization efficiency of urban land and water resources in China generally shows a slow upward trend, but the efficiency values are not high. The comprehensive utilization efficiency of land resources shows the spatial pattern of Eastern>Northeast>Western>Central. And the comprehensive utilization efficiency of water resources shows the spatial pattern of Eastern>Western>Central>Northeast. (2) The coupling coordination of urban land and water resources utilization efficiency is in the general coupling coordination stage, and the land resource efficiency lag is the main type. The spatial-temporal patterns are significantly different, showing the spatial distribution pattern of “East>West>Northeast >Central”. The eastern region is in a good coupling coordination stage, and the northeast, central and western regions are all in the average coupling coordination stage. (3) The coupling coordination degree of urban land and water resources utilization efficiency in China shows a significant positive spatial auto-correlation, which is mainly concentrated in “high-high” and “low-low” areas,with a trend of polarization.
