摘　　要：基于2011-2020年中国19个城市群208个城市的数据,运用超效率SBM模型测算得出各城市水资源利用效率状况,实证检验了科技创新对水资源利用效率的作用机制、异质性以及空间溢出效应。结果表明:科技创新对水资源利用效率的提升具有显著的推动作用,且存在空间溢出效应。进一步分析发现:科技创新推动水资源利用效率的提升具有区域异质性,且在部分城市群显著;产业结构升级在科技创新对水资源利用效率的影响中起到传导作用,且这种传导机制在东部地区、胡焕庸线以东、宁夏沿黄和山东半岛城市群更为显著。据此,提出提升城市群水资源利用效率的对策建议。Based on data from 208 cities across 19 urban agglomerations in China from 2011 to 2020,this study employs the Super-Efficiency SBM model to assess water resource utilization efficiency of each city and empirically investigates the mechanisms,heterogeneity,and spatial spillover effects of technological innovation on this efficiency.The findings indicate that technological innovation signifi-cantly enhances water resource utilization efficiency and exhibits spatial spillover effects.Further analy-sis shows that the impact of technological innovation on water resource utilization efficiency varies region-ally and is particularly significant in certain urban agglomerations.The upgrading of industrial structure serves as a mediating factor in the relation between technological innovation and water resource utiliza-tion efficiency,with this mediating effect being more pronounced in the eastern region,east of the Hu Line,as well as in the Ningxia section along the Yellow River and the Shandong Peninsula urban ag-glomerations.Consequently,countermeasures and suggestions are provided to improve water resource utilization efficiency in urban agglomerations.
