Research on Pricing Mechanism of Water Rights Trading Along the South-to-North Water Diversion Route Based on Ecological Economic Effect
Aiming at the pricing mechanism of water rights trading in cities along the South-to-North Water Diversion Project,this paper studied the pricing mechanism of water rights trading by using energy theory of ecological economics and game theory.Firstly,considering the ecological and economic losses of the seller and the ecological and economic benefits of the buyer,the quantitative system of the ecological and economic effects of water rights trading along the South-to-North Water Diversion Project was proposed by energy theory.Then the cooper-ative game model of water rights trading was constructed,and the Nash negotiation solution method was used to determine the game price of water rights trading.The calculation results of Pingdingshan-Xinmi City show that the game prices in 2016-2018,2021 and 2030 are 0.50 yuan/m3,0.54 yuan/m3,0.74 yuan/m3,1.04 yuan/m3 and 1.16 yuan/m3,respectively.Compared with the actual transaction price of 0.78 yuan/m3,the game price can better reflect the influence of water resources abundance and shortage on water rights trading price.
