Game theory, also known as game theory research is the behavior of the decision-making body in the event of a direct interaction, how people how to achieve a balanced decision-making as well as decision-making. Game theory is the study of rational theory of conflict and cooperation between policy-makers. Game theory analysis of each chess on certain occasions in deciding what action to take strategically destination of acting, he considered his decision-making behavior may affect others, as well as the behavior of others on He may affect, by selecting the best plan of action, to seek benefits or utility maximization. In this paper, decisions made by rational game theory to study of this decision is to want to come out under what conditions, and analysis of the reasonableness of a process of the idea and decision-making. This article is mainly from a philosophical point of view to prove the rationality of game theory, game theory of rationality analysis process is mainly divided into the following three questions to elaborate layer by layer: The first question is reasonable Nash equilibrium, Nash equilibrium is reasonable, he eventually implement the above the reasonable game theory to establish the reasonableness of the moral, regardless of the Nash equilibrium or Nash bargaining solution reasonable, both of these problems can be attributed to a problem moral reasonable, that is, we usually think of the decision-making rational, reasonable, Nash equilibrium that he could not solve many problems, because this game theory reasonable that the Nash equilibrium game theory rational reasonableness of the assumptions, which in the final analysis is a moral problem, rational and reasonable, Nash equilibrium unable to solve the key problems is that the rationality of morality. Typical model of game theory: the problem of the prisoner's dilemma is that the individual's reasonable, in the pursuit of their own interests to maximize the decision-making of the game, he is itself dependent on the interests of the spontaneous, but spontaneous such a balance, he can not reach a collective optimal, that is optimal individual interests in real life is not equal to the collective interests of optimal, Nash equilibrium explore the collective interests optimal, but the collective optimum, the rationality of the collective rational decision-making also encountered Prisoner trouble a fundamental question: is best to find a collective interests, there must be a moral framework, there must be a social equity and social norms on the inside. Nash actually solve this problem, the biggest difficulty facing the same is rational choices facing the moral rationality. The second problem is to meet the moral rationality. Premise is necessary to ensure the integrity of the information, that is, in the conditions of symmetric and asymmetric information the reasonable ethical issues, such a moral rationality of his final implementation is dependent on the degree of master in the overall information, so and thus need to study the question of the rationality of complete information. However, the first question the moral and integrity of the information reasonably ideal state to the final development of the socio-cultural, social, historical and interpersonal conflict of interest, in order to get the complete information is difficult to be done. Therefore, we want to re-from a different angle to examine the reasonableness of the problem. The third problem is the evolutionary game theory rationality. In front of two reasonable are based in our study countermeasures rational analysis of the static analysis which level up, he can not fully reflect the social and cultural changes in the background of the decision-maker or state, which we need from the static analysis converted to a dynamic analysis model up to study the question of the rationality of the evolutionary game theory. Evolutionary Game Theory to abandon the assumption of perfectly rational, from system theory, group behavior adjustment process as a dynamic system, actors are assumed to be programmed to a given behavior, it is the economic laws or some successful rules of conduct, understanding of the behavior policy is constantly revised and improved in the process of evolution, a successful strategy to be imitated and, thus, some general rules and institutions, as actors Action Standards. These general rules, the actors get a satisfactory income. Eradicate market, according to the conditions of social and cultural change, to adjust the behavior of the decision makers to analyze the evolution process of the game is reasonable. In the history of the evolution of the social and cultural changes within the range of conditions, such conditions, ultimately depends on the rationality of the evolutionary game theory.
