Evolutionary Game Simulation: A Case In Water Resources Management

In this paper it simulates the dynamic evolution of water ecosystem by the evolutionary game theory. Through analyzing the theoretical hypothesis and model simulation, it finds that strategic choices of players are decided by payoffs of actions when water quality under certain conditions, there exist stable evolutionary equilibrium between water quality and players mixed strategy when payoffs of player' actions are exogenous variables. By simulating combined system dynamics in water resources, it finds that government can choose appropriate taxes and subsidies according to different water quality state if resource of river basin ecology has the ability to regenerate, so that stakeholders have to change their strategic choices, which make the combined system evolve to the optimal equilibrium..
