Model of network community public opinion spread based on game theory

In order to solve the dynamic and interactive community of internet of public opinion's spread,this paper proposed the game theory.Game strategies under the conditions of dynamic probability constituted the game tree and payoff matrix.From both internal and external community of internet,it analyzed the dynamics of public opinion spread.The model could describe the dynamic and interactive communication process,and could form a stable state at last.Simulation results show that public opinion in the community of network spread in the general case with the early spread of smooth,and gradual tendency of a party to the formation of public opinion has a certain impact.
