The application and influence of game theory in the choice between achieving self-worth and social value in life. Different game rules dictate the decision to maximize self-interest, and self- and social values are considered to reach the Pareto optimal state. A reasonable allocation of self-value and social value is achieved using the crosswalk game as a reference. The results show that using the game theory model can yield a maximum value of 0.0001 for the rate of change, indicating an interaction between life self-value and social value, which helps to make subsequent timely responses to improve self-cultivation and strengthen normative behavior.
