Abstract:

In order to scientifically calculate the administrative expenses and solve the problem that the equilibrium between all the participants can not be gotten by the existing method, game theory is adopted to analyze the dynamic game process between taxi company and driver, the profit function of each game path and the equilibrium conditions of each participant. By solving the optimal sub-game Nash equilibrium, the calculation method for administrative expenses range is developed. Furthermore, taking Xi’an taxi as an example to prove the validity of computational method, the fundamental basis for decision making of administrative expenses calculation of city taxi is presented. The studies indicate that the realization condition of interest maximum for each participant is whether they choice the beneficial strategy with greater probability. The administrative expenses calculation from the perspective of interest game can achieve both income balance and alleviate conflicts of interest. The reasonable range for Xi'an is 4 022–5 840 yuan/(month ⋅ veh), that is, there exists an intense interest conflict of 72% of taxi. This conclusion is consistent with the actual, and further verifies the credibility of the calculation method.
