JAUE2022-117: Theoretical Analysis of Reclaimed Water Pricing based on Cooperative Game Theory

Abstract

Urban sewage reuse refers to the reuse of treated urban sewage in the aspects of farmland irrigation, industrial cooling, municipal greening, road spraying, groundwater recharge and surface water supplementation according to the water quality and water quality requirements. This water resource is also called reclaimed water. Reclaimed water reuse can effectively solve the water shortage crisis, but in the process of reclaimed water reuse in China, how to set the price of reclaimed water scientifically and rationally has not yet formed a perfect system. This paper mainly introduces the role of cooperative game theory in the study of the theory and method of urban reclaimed water pricing, and studies the subject, price theory, and pricing method of reclaimed water pricing. According to the different pricing subjects, it is divided into two cases: the independent pricing of urban reclaimed water production enterprises and the pricing controlled by the government, and the pricing issues are studied separately. The study found that the construction of a market system for reclaimed water reuse requires active guidance and support from the government
