This paper selected panel data from 17 provinces(regions,cities)in China's"Belt and Road"China region from 2010 to 2020,e-valuated the water resources utilization efficiency by introducing the super efficiency SBM model,and used the Tapio decoupling model to ana-lyze the synergy between the water resources utilization efficiency and economic and social development.The results showed that the average water resource utilization efficiency of the 17 provinces(regions,cities)generally followed the pattern of Southeast>Southwest>Northwest>Northeast.They could be roughly divided into three tiers.Among them,the average water resource utilization efficiency of Qinghai,Chongqing,Guangdong and Ningxia had all exceeded 1.000 0 in the 11 years,while Xinjiang had the lowest average value of only 0.093 5.From the kernel density distribution results,the overall gap in water resource utilization efficiency in the region had been reduced to some ex-tent.The relationship between water resource utilization efficiency and economic and social development was analyzed with a window width of 3 years and the entire research period,the results showed that the adaptability status had a phased change characteristic and strong spatial differ-ences.Among them,Jilin showed the best synergy,while Hainan,Qinghai,Shaanxi,Guangxi and Chongqing showed a strong decoupling sta-tus.Most other provinces(regions,cities)were in the weak decoupling status and needed to improve the water resource utilization efficiency while ensuring economic growth and urbanization process.
