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. Introduction The Fifth Plenary Session of the Eighteenth Central Committee of the Eighteenth Party of the Party proposed that water is the foundation of survival, the source of civilization, and the essence of ecology. In order to better support China s water conservancy in building a well-off society in an all-round way, the party and the state have proposed new ideas for water management [1,2]. Water resources and water environment have become the bottleneck restricting China s current economic and social development. How to balance water resources, water environment and economic development, and coordinated regional development has become a top priority. Water resources, water environment, water environment and people s living and health. It is closely related and is also the most important public product and production material. How to improve the utilization efficiency of water resources and improve the carrying capacity of water resources is a hot issue in current research. The mainstream scholars at home and abroad believe that the meaning of water resources carrying capacity is that water resources carrying capacity is the water resources of a certain region under a specific historical development stage, based on predictable technical, economic and social development levels [3,4].The principle of sustainable development is to maintain the virtuous circle of ecological environment as the condition, and after reasonable allocation and optimization, the maximum support capacity for the socio-economic development and population size of the region. Therefore, based on the input-output view and DEA analysis method, this paper constructs the evaluation model of water resources utilization efficiency in Jilin Province, and analyzes the water use efficiency of various cities in Jilin Province, and gives policy recommendations for water resources carrying capacity regulation [5]. Method Data Envelopment Analysis is a multi-factor productivity efficiency evaluation method, which is firstly proposed by Charnes A, Cooper W, and Rhodes E in 1978. The principle of this method is to treat each object of evaluation as a decision-making unit (DMU), keep the output or input of DMU unchanged, and determine the relatively effective production frontier, and then project each DMU onto the production frontier, and their relative efficiency is evaluated by comparing the deviation from the DEA production frontier[6,7].
