Research On Utilizing Conflict Of Water Resource And Initial Water Right Allocation In A River Basin Based On Game Theory

Currently, the study of water resource utilizing conflict problem and the study of initial water right allocation problem in a river basin are the main research contents which draw the attention of water conservancy circles and economics circles. In order to guarantee and promote the river basin sustainability development, it is necessary to analyze and study water resource utilizing conflict problem; therefore, in this paper, game theory method is applied to studying the water resource conflict problem of river basin, the initial water right allocation problem of river basin, the cut-off problem of the Lower Reaches of Tarim River, and the initial water right allocation problem of Tarim River.(1) Non-cooperative game model with multi-players, repeated game model, and evolutionary game model were employed to study the water quantity utilizing conflict problem of water resource in a river basin. Analyzing and comparing the equilibrium results of the above non-cooperative game model lead to some methods and mechanisms, which can solve the water resource utilizing conflict problem in a river.(2) Non-cooperative static game model, complete cooperative game model, and non-cooperative dynamic game model were used to study the water quantity and water quality double utilizing conflict problem of water resource of a river basin. By analyzing the equilibrium results of the above models, this paper obtains the conclusion that adopting macroscopical control measure of market economy can resolve the conflict and inconsistency of the water quantity and water quality double utilizing of water resource of a river basin effectively, realize the benign circulation of the water quantity and water quality double utilizing of water resource in a river basin, and then promote the river basin sustainability development. Non-cooperative game model was applied to analyzing and studying the supplying problem of water-saving social capital of the water resource users in a river basin. By analyzing and comparing the equilibrium result of the game model, this paper finds the key factors which control the supplying level of water-saving social capital of the water resource users in a river basin.(3) Duopoly game models with complete information and incomplete information and the auction game model are applied to analyzing and studying the initial water right allocation problem in a rive basin. An equilibrium model for tradable water right and pollution right "quasi-market" is established under the condition that the transaction costs, the transferring costs and decontamination for return flows water, and the environment constraints are considered. The results of the equilibrium model are analyzed, and then a sufficient and necessary condition for a set of bidding strategies of water right and pollution right buyers being the Nash equilibrium of bidding game is given.(4) Based on the theory of non-cooperative multi-objective game, the problem for the cut-off and water quality deterioration of the Lower Reaches of Tarim River is studied. On the basis of the initial water right allocation game model, the initial water right allocation schemes for Tarim River are obtained. Based on the decomposition-coordination principle of large-scale, a cooperative game model for the urgent water deliveries to the Lower Reaches of Tarim River is established and solved. The reasonable allocation results of water quantity for various sub-regions of the Lower Reaches of Tarim River are obtained.
