Research On The Impact Of Information On Cooperative Behavior From The Perspective Of Subjective Game

This paper studies the influence of information factors on the cooperative behavior of the subject based on subjective game theory and experimental economics.The information we mention here mainly includes two aspects.On one hand,it is the feedback information that the participants get in the process of playing the game;On the other hand,it refers to the display of information about the structure of the game.Specifically,this paper designs experiments to study the effects of feedback information,prior knowledge and initial known strategy information on participants' game learning.And then explore its impact on the cooperative behavior of participants.Game theory starts with focusing on cooperation.Both the classical game theory and the evolutionary game theory provide an important tool for the research of cooperation.However,the traditional game theory is based on the assumption that the participants know the rules of the game.In real life,people often have no concept about the game they are participating in,and they are more likely to participate in the game in a state of unconsciousness.Therefore,more and more scholars begin to study cooperation based on subjective game theory.The subjective game theory(also called inductive game theory)holds that the participants do not have the relevant knowledge about the game rules.In the process of repeatedly playing the game,they can form subjective opinions about the game rules through learning and induction.Because of the difference of participants' cognitive ability,their subjective views on game rules are not necessarily consistent with the objective game rules.With the repetition of the game,participants will gradually update their own subjective views and form convergence,which is more in line with the reality of the society.Therefore,based on the subjective game theory,this paper studies the influence of information factors on the cooperative behavior of participants,and then explores the mechanism of cooperation norms.In the study of the influence of information feedback on the cooperative behavior of participants,we create a complex environment by mixing the two game structures to study the behavior of participants in multiple games with little information feedback.The experimental results show that information feedback plays an important role in the behavior selection of participants.In the case of little information,the participants can still learn the objective matrix of the game,but compared with more information,the level of cooperation between the participants is reduced.On this basis,we further explore the influence of prior knowledge on the cooperative behavior of participants.In the experiment,we used two terms,cooperation and betrayal,to describe the choice of two strategies.Because of the different educational background and personal experience of the participants,each participant will have different initial understanding of the game they are going to participate in.We want to explore the influence of this priori knowledge on the behavior choice of participants in an unknown game environment.The results show that prior knowledge has a significant impact on the behavior choice of participants,and the overall level of cooperation of participants has been significantly improved compared with the expression of strategies without prior knowledge.Therefore,we conclude that the education of cooperation concept has an important impact on improving the overall level of cooperation.All the above studies were carried out without the participants knowing the game matrix at all.In order to explore the impact of initial known strategies on participants' cooperative behavior,we show participants part of the game matrix information to study the behavior selection of participants in the state of partial understanding of the game matrix.The experimental results show that the initial known strategy has no significant effect on the participants' behavior choice,and the participants' behavior choice is mainly determined by the consideration of the outcome of the strategy income in the repeated participation in the game.In addition,we find that the cooperative ratio of the participants with partial understanding of the game matrix is lower than that of the participants who know the game structure completely,and this ratio is even lower when the participants do not know the game matrix at all.From this we conclude that it is easier to promote cooperation in the case of information transparency.
