Abstract: Urban public transportation finance subsidy is one of key links which implements promoting public transit priority strategies. It is an important issue of urban traffic sustainable development to establish a specific operable subsidy calculating model and improve the way to calculate urban public transport subsidies. The paper establishes the game model among the income of residents, enterprises operating costs, and subsidies through utility theory. It shows the advantages of classification subsidy of public transit riders, and establishes a specific operable subsidy calculating model. Then, the calculation of Beijing public transit subsidies in 2007 is taken as an example. The results indicate that the way to classification subsidy and the subsidy calculating model not only can fully satisfy the travel demands of public transport riders but also can effectively calculate the subsidy amount, which realizes the utility maximization of government subsidy. The proposed method is proved to be a new effective way to calculate urban public transit subsidy.
