Abstract: A two-person evolutionary game model is established in the condition of bounded rationality. Based on the implication of equilibrium point determinant and trace, the evolutionarily stable strategy under 16 situations is analyzed, the decision process from stability analysis of equilibrium point is discussed, and the mechanism of strategy selection is revealed from the strategy comparing perspective. The results show that the evolutionarily stable strategy of game system is determined by the relative net payoff under different strategies. The basic influencing factors of one’s decision include adverse strategy choice and his payoff comparing of strategy. The game participant tends to choose the greater payoff strategy in the condition of adverse strategy fixed. Finally, we take the game between local governments and between local government and enterprise in pollution treatment for example. The application value in policy design of model is illustrated. For different cases, as long as the payoff matrix of the two person game is cleared, the behavior evolution rule and stable strategy will be determined by calculating relative net pay, so as to simplify the calculation process, and provide theoretical reference for policy design more directly and more easily.
