A comprehensive indicator of water use efficiency (WUE) to promote coordinated development between socio-economic and environmental systems was developed. A comprehensive consideration of the social, economic and environmental benefits of water was made in the evaluation index system of WUE and the projection pursuit model combined with chaotic particle swarm optimization was adopted to calculate the comprehensive indicator of WUE. The Huai River Basin (HRB) was selected as a case study area. The temporal change of WUE showed that the annual WUE of the HRB from 2007 to 2013 increased obviously because of the enhanced emphasis on environmental protection by the government. The spatial results showed that the spatial WUE of each province in 2013 was significantly higher than in 2007. In 2013, Anhui with the lowest WUE was selected as representative to reveal the problems of water use in the HRB. The main reasons were that the government paid more attention to the high water consumption industries and ignored the small-scale water users, and wastewater treatment was still weak in the HRB. The research can provide the foundation for improving WUE and solving the problem of water shortages.

In order to achieve the sustainable utilization of water resources and the sustainable development of the economy, an evaluation index system for water-use efficiency and economic development systems was constructed. The entropy weight and the comprehensive evaluation methods were adopted to determine the index weights and conduct a comprehensive evaluation for the two systems. A coupling coordination model was used to calculate the coupling degree, coordination degree, and coupling coordination degree of the two systems. The annual coupling stage and coupling coordination intensity of the two systems were analyzed and determined. The results showed that the comprehensive evaluation values of both the water-use efficiency system and the economic development system in Jinan increased greatly from 2008 to 2017, and showed a changing trend of ups and downs. The two systems were in the antagonistic stage, and were gradually approaching the running-in stage, indicating that they were in the state of common development. The coupling coordination degree of the two systems gradually increased in waves, progressing from moderately to highly coordinated coupling. In the future, if the water control path appropriate to Jinan can be explored actively, the water-saving kinetic energy of economic development can be increased constantly, and the linkage effect between economic development and water resource utilization can be given full play. The two systems will then be in sync, enjoying a benign interaction and a healthy harmonious development.
