Analysis of Water Resources Utilization Efficiency in Jilin Province Based on DEA Method

Abstract

Based on the DEA analysis method and input-output principle, this study selected the natural water resources, water resources input and social economic indicators of Jilin Province to construct the water resources development efficiency model of Jilin Province and the water resources utilization efficiency model of Jilin Province. Using the above model to evaluate the water resources development and utilization efficiency of various cities in Jilin Province. Studies have shown that one-third of the prefecture-level cities in Jilin Province have low water use efficiency and have great potential for improvement. Policy recommendations have been put forward for the improvement of water use structure and water use efficiency. The research shows that the water saving potential of Jilin Province is 1.343 billion cubic meters, and the potential GDP will increase by 63.4 billion yuan due to the improvement of comprehensive water use efficiency.
