Evaluation of Water Resource Utilization Efficiency Based on Super-Efficiency DEA: A Case of Hubei Province

How to improve the utilization efficiency of water resources is the central issue of building a water-saving society. Realizing the sustainable development of water resources is a difficult problem facing the continuous development of the economy and society of Hubei Province. Therefore, this study chose the super-efficiency DEA model to analyze and study the water use efficiency of twelve cities in Hubei Province from 2014 to 2018. It was found that only Wuhan’s super-efficiency increased every year, proving unreasonable in water utilization efficiency of other 11 cities. Based on the super-efficiency value, the study used tobit model to analyze the e the impact of the efficiency of water resources utilization from the three aspects including society, nature, and industry, and it was concluded that socioeconomic factors and water use efficiency were positively correlated, and the other two were negatively correlated. Finally, this study put forward four improvement measures based on the above results.
