Pricing of resource water price for the Central Yunnan Water Diversion Project based on set pair analysis and game theory combination weighting
Based on the basic data of the Central Yunnan Water Diversion Project,five evaluation indicators were determined,includ-ing the water quality of the water source area(X1),per capita water resource occupancy(X2),per capita GDP(X3),domestic sewage treatment rate(X4),and population density(X5)according to the principles of independence,quantifiability,and accessibility.By us-ing a set pair analysis and connection number model to calculate the resource water price and determine the evaluation matrix of the re-source water price index,the D-AHP method and entropy weight method were combined and weighted using game theory.The re-source water price vector was determined by combining the water price bearing index and residents'bearing capacity,and the re-source water price was calculated.The results showed that the water price for residential water resources in the Central Yunnan Water Diversion Project was calculated to be 1.75 yuan/m3 based on the correlation matrix between five evaluation indicators and evaluation levels.The higher the water quality and population density of the water source,the lower the resource water price;the higher the per capita water resources,per capita GDP,and domestic sewage treatment rate,the higher the resource water price.The calculation re-sults could provide reference for determining the water price of residential water resources for the Central Yunnan Water Diversion Project.
