경제위기하의 저가항공사 출범: 한국항공산업 사례

초록

As the wave of liberalization and deregulation accelerated to relieve rigid controls over airline routes, capacity and fare setting regime, Low Cost Carriers(LCCs) have emerged especially in local aviation markets since 1970s. This paper has studied effects of LCC's entry on domestic aviation market which was pre-occupied by two major carriers, Korean Air(KAL) and Asiana Airlines. Through a simple model describing prior and post to LCC's entry situations, we analyzed changes and trends of airline's output and profit with Cournot and two-stage Stackelberg games. In summary, our conclusion has developed five points: (1)Even though JIN Air's entry reduce KAL's respective output and profit, the more JIN Air produce, the higher joint-profit of KAL and JIN Air is, (2)From the joint-profit aspect, increasing KAL's output than JIN Air's is more profitable on Gimpo-Jeju route, on the other hand, increasing JIN Air's output than KAL's is more profitable on Jeju-Busan route, (3)Even though JIN Air's entry increase Asiana Airline's output, the more JIN Air produce, the less Asiana Airlines's profit is, (4)Total output in markets as well as total profits of firms will increase in a certain condition, (5)KAL and JIN Air tend to get caught in an unresolved conflict on level of LCC cost.
