This paper starts from the classic case of ’’Prisoner’s Dilemma" in game theory, and investigates the prisoner’s dilemma model from single game to repeated game by combining cooperation indices such as social values and beliefs, and discusses the maximum benefit function of the participants when they adopt "tit for tat (TFT)" strategy and ’trigger strategy (TS)" respectively. " strategy and ’trigger strategy (TS)", and finally analyzed how these cooperation indices affect the mechanism of cooperation in repeated games, and finally argued the equilibrium difference between prisoner’s dilemma in single game and repeated game, and illustrated that under repeated game conditions The possibility of cooperation arises under the conditions of repeated games.
