Abstract

This paper analyzes a competitive shipping market in East Asia in order to explore how container carriers make decisions on ship size, number of ships, service frequency, and service route. A sequential-move game based on non-cooperative game theory is applied to establish the models for the decision-makings involving the transportation volumes, freight rates, costs, and market shares of the service routes from Shanghai or Hong Kong to the ports in Busan, Gwangyang, and Incheon. According to the sub-game perfect Nash equilibrium solutions proposed by these models, carriers' decisions in such a competitive environment vary depending on sailing distance, transport demand, and freight rates. Therefore, carriers are recommended to reflect the optimal equilibrium solutions and a variety of decision factors when formulating strategies for transportation networks and operating fleets. Furthermore, ports should establish management strategies for these factors to provide optimal equilibrium solutions for carriers' transportation networks.

본 논문은 컨테이너 선사들의 선형, 항로 및 항차의 결정방법을 구축하기 위해 동아시아지역의 경쟁적인 해운시장을 분석하였다. 상하이항과 홍콩항으로부터 국내의 부산, 광양 및 인천항향 서비스 항로에 운송량, 운임, 원가, 그리고 시장점유율을 기반으로 한 모형에 비협조적게임이론에 기초한 순차진행게임을 적용하였다. 이러한 모형의 문제를 풀도록 제안된 하위게임 완전 내시균형해에 따르면, 경쟁환경에서 선사들의 의사결정은 운항거리, 운송수요, 그리고 운임수준에 따라 달라지는 것으로 분석되었다. 그러므로 선사들은 운송네트워크와 최적선대에 대한 전략을 구성할 때 최적균형해를 이용하고 이를 위해 다양한 의사결정 요인들을 동시에 고려해야만 한다. 추가적으로, 항만들은 다양한 요인들을 이용해 각 항만이 선사 운송네트워크의 최적 균형해를 제공하기 위한 경영전략을 구축해야만 할 것이다.
