Green Travel Behavior Based On Theory Of Planned Behavior And Game Theory

With the rapid development of China's economy and the acceleration of urbaniza-tion,China' s air pollution has become more serious and has reached a point where it cannot be underestimated.In this context,it is of great significance to study the green travel behavior of urban residents.The theory of planned behavior is mainly described and proposed based on social psychology.It is less studied from the perspective of indi-vidual strategy and individual utility.Therefore,this paper combines the theory of plan behavior and game theory to study the green travel behavior of residents.With a view to providing some valuable and meaningful conclusions for environmental governance.In order to explore the green travel behavior of residents(individuals)and the in-fluencing factors and mechanisms of green travel behavior,in this thesis,the research status of the green travel behavior at home and abroad is firstly combed,and on the basis of summarizing the existing related literature,an individual green travel behav-ior influence mechanism model is established based on the theory of planned behav-ior.Simulation analysis results show that when certain conditions are met,when the propagation of green travel knowledge breaks through the critical point,the number of individuals choosing green travel will usher in an explosive growth and eventually stabilize at a very high level;However,when individuals face substantial difficulties in choosing green travel,even if the residents have a high level of knowledge about green travel,the overall willingness to travel green is also low.Secondly,considering the characteristics of green travel behavior,considering the individual's“health benefits","reputational benefits",and "trip costs",we con-struct the individual utility function,and use the network evolutionary game theory to establish the relevant model.Analyze the impact of individuals' individual utility on the choice of travel strategies.The research results show that "health benefits","repu-tational benefits" and "trip costs" will have an important impact on individual travel behavior,by raising residents' awareness of the positive effects of green travel,cultivat-ing residents' sense of green travel,and reducing green travel costs,the overall level of green travel can be effectively improved.Finally,considering the individual heterogeneity,we use stochastic differential game to analyze and model the individual's travel choice behavior,considering the individual's“economic utility"and "healthy utility ",the individual's travel utility function is given to explore the effect of individual heterogeneity on the travel utility function and the impact of individuals'non-green travel behavior on air quality.The degree of difference between the two types of factors on the choice of individual travel strategies.The results show that the individual's heterogeneity in the utility function will have an important influence on the individual's travel strategy choices,but the difference in individual's non-green travel behavior's influence on the air quality status has no effect on the individual's travel strategy choice.
