The Research Of The City Group’s Evolutionary Game

In the21st century, the urbanization process in our country further speedup.When the new city group is being built,it is very important to research therelationship between the cities in the city group.At first, this paper focus on repellent and symbiotic of cities economic group, tryto find the way of cities’ cooperation. In order to achieve this goal, the paper uses thebasic principle of evolutionary game, builds the repellent and symbiotic modelbetween cities. According to the set of payoff function of the game, we can find theeffect factors which decide the evolutionary stable strategy solution of.the city game.By this way, we can put forward suggestions and requirements to make cities tocooperate.Then,the paper make a study of evolutionary game in the limited citygroup.With the cities as the basic unit, Moran process as the basic principle, birth anddeath process for tools, neutral drift as the standard, to research the fixed probabilityof the strategy in city group’s evolutionary game.And propose the concept about theevolutionary game stability of limited city group. Coming with the structure of citygroup, this paper use evolutionary graph theory to study the effect of differentstructure of city group on the city network game,and find out the characteristics of thestructure which add weight to the influence of favorable policy.Starting from cityregionalization,we can establish a spatial grid game model of city group to find outthe essential condition and some problems to make cities to cooperate.
