Abstract: Game theory is one of the most effective ways to solve the balance problem of all parties in the same environment. But fundamentally, the contradiction between seat rate and ticket price is always the most prominent problem in the pricing model. Based on the game between airlines and passengers as the model, a dynamic model is set up to balance the seat rate and ticket price. The original model is analyzed and optimized in theory using knowledge and tools including incompatibility problems and solutions, divergence tree, extension transformation and extension set. According to the characteristics of this model, the model for civil aviation ticket prices and load factors not only provides a solution to the contradiction between, but also applies to a certain extent in solving other perishable product sales prices and sales in the contradiction.
