自 從開放天空政策以來,航空公司為因應國內市場之激烈競爭,紛紛採取加開班次與降低票價之促銷行為,加上最近飛安事故頻傳, 導致航空公司之載客率下降,獲利能力大減。甚至質疑是國內航空公司過多,導致削價競爭而忽略飛航安全。故部份業者遂呼籲有關當局將國內航空公司合併,以減 少家數,或可藉由航空公司間合作行為,提高彼此的營運效能,從而提高飛航安全與服務品質,以達到另一種形式之減少競爭家數。 事實上航空公司間不斷有各種購併與合作行為,因為藉由合作可減少營運成本、提高收益、增強競爭力。本研究希望以合作賽局理論來分析此一合縱連橫之互動行 為,並從而解構航空公司間票價之競爭模式。本研究將先回顧合作賽局理論之基本定理與假設,探討核心解(Core)、夏普利值(Shapley value)及核仁(Nucleolus)之定義與求解方式,並探討航空公司在透過聯營 (pool) 之合作型態下,其報酬函數之建構與票價競爭之均衡求解。 報酬函數是由下列模式建構而成:需求模式與成本模式,其中需求模式由載客率模式與市場佔有率模式推估。報酬函數建構完成後,本研究依合作賽局理論分別建立 其在不同的組合下之最佳票價,以求得各組合之報酬值;而市場均衡之求解,是基於航空公司追求最大利潤之觀念,應用核心解、夏普利值及核仁等理論來求得。最 後以國內航線來做實證分析。 為構建國內航空公司聯營競爭市場之行為模式,本研究於1999年一至四月間,進行「台北到台南與台北到高雄旅客對航空公司選擇偏好」的問卷調查,依個體選 擇理論校估各情境航空公司於北高航線市場佔有率模式的參數。本次調查係以搭乘台北飛台南與高雄班機之旅客為調查對象,參數校估結果顯示,票價及班次數在本研究之市場佔有率模式中,均為明顯的決策變數。由實證分析可以看出隨著聯盟家數的擴增,導致班次增加,如此一來聯盟將對航空票價越來越有壟斷力,即聯盟之 票價有上升之趨勢。

Since1987, the deregulation of the airline industry, all major domestic airline companies have faced enormous competition in order to secure its market share and accumulate maximum profit. Many have questioned that the quality of the domestic airline industry has not been improved. The reason is because of the keen competition between many flight carriers. Others have suggested the authority to encourage airline merging in order to reduce the negative impact in the market. However, the hypothesis of this research is that by the means of cooperation, the operation proficiency, flight safety, and service quality could be improved. As the matter of the fact, the focus of this research is to construct a proper pricing model through the analysis of the current existed alliances. The reviews of the literature in the application of the alliances as the cooperative games will be carefully synthesized by discuss the definition and the resolution process of Core, Shapley value and Nucleolus. The practice of the pool in the current cooperative market will also be illustrated through the construction of the payoff function and the solution to of market equilibrium under. Three major components of the payoff function are as followed: the demand model, the market share model, and the cost model. After the completion of the payoff function, this research uses theory of the cooperative game to find the most profitable price under different scenarios. Based on the profitable prices, the payoff values that correspond with the maximum profits, of the airline companies are obtained. To conclude this research, a case study of a domestic market is presented to verify the effectiveness of this model.
