| Research Objectives: Measure the water utilization efficiency in stages and in departments, and analyze its spatial interaction effect. Research Methods：Build a DEA model based on the hybrid network structure of water system to measure the water utilization efficiency, and use Moran's I index and impulse response function to analyze its spatial interaction effects.Research Findings：During 2006~2015, the overall water efficiency in China was low; the initial water use efficiency was higher than the wastewater treatment efficiency, and the household water efficiency was higher than the industrial water efficiency; the comprehensive water utilization efficiency had significant spatial interaction effects, and the central region had an important influence on the synergy enhancement of national water utilization efficiency.Research Innovations： Improve the accuracy of efficiency by introducing the new multiple hybrid returns-to-scale technology to eliminate input-output mismatch problem.Research Value：Optimize the water system based on efficiency measurements to achieve efficient water utilization, and coordinate the regional water usage based on spatial effects to realize the spatial synergy enhancement of water comprehensive utilization efficiency. |
