| Summary: | 碩士 === 淡江大學 === 運輸管理學系 === 89 === In recent years, the competition among airlines becomes more vigorous than before. As a result, airlines tend to form alliances to promote their service quality and to enhance their competitiveness. When alliances such as “Star Alliance” and “One World” become to dominate, it is more difficult for individual airlines to survive in the competition.
Code-Sharing agreement is the most popular way to among all types of cooperation. There are two different types of code-sharing, in practice: One is “parallel”, and the other is “complementary”. The parallel cooperation can increase fright frequency, and the complementary cooperation can extend the scope of service. The study is focus on the complementary type of code-sharing agreement, and using the game theory to analyze the costs and benefits before and after code-sharing. The information provides the airlines manager to evaluate the effectiveness of their code-sharing agreement.
There are three major components of the payoff function: the demand model, the market share model, and the cost model. Based on the estimated payoff function, this research applies the game theory to find the most profitable airfares under different cooperative scenarios. Given the optimal airfares, the corresponded payoff values of the airlines are obtained. Comparison of the profits and consumer surplus under various scenarios are shown in chapter 7. A case study of the code-sharing practices between Taipei to San Francisco and Taipei to Bangkok is presented to verify the effectiveness of this model.
