If a system has a large boundary and complexity, forecast's accuracy will be very low when consider the system's substance as black box. Thus, it is necessary that analysis by structure model. To examine competition in Northeast Asia Ports, it has assumed that the form of structure model, For which the System Dynamics method is adapted in this paper. Northeast Asia Ports Model includes five ports - Pusan, Kobe, Yokohama, Kaoshiung, Keelung, - which are adjacent to each other by geographically and has a competition relation. The Northeast Asia Ports Model has several sub-systems which consists of each unit port models. And, each unit port model found by quantitive, qualititive factors and their feedback loops. All effects which components of one port have influence to components of the rest ports must be surveyed in order to construct Northeast Asia Ports Model, but it may be impossible currently. In this paper Northeast Asia Ports Model was simplified by HFP-Hierarchical Fuzzy Process Method-adapted to integration of level variables of unit port model. Container cargo volumes in Northeast Ports Model is distributed by results of HFP method. And distributed container cargo volumes effected to unit port model. Developed model can estimate change of container cargo volumes in competitive relation by alternation of simple parameter, and reflects dynamics characteristics which are included in model.

본 논문의 목적은 동북아항만간 경쟁 입지변화와 경쟁관계 분석을 통해 광양항의 발전전략을 구축하는 것이다. 동북아 주요항만간 경쟁 입지 변화추정을 위해 수정 BCG매트릭스, 그리고 경쟁관계분석을 위해 Lotka-Volterra모형을 활용하였다. 연구결과 동북아지역에서는 중국항만의 경쟁력 및 영향력 확대, 부산항의 경쟁력 유지와 광양항 및 인천항의 경쟁력 정체, 그리고 일본항만의 경쟁력 실종을 확인했다. 또한 2007년 대비 2014년의 동북아 항만과 광양항간 관계에 따르면 환적물량기준 광양항은 부산항과 윈윈관계에서 약탈적 관계로 변화되었으며, 홍콩항과는 약탈적 관계를 유지하였다. 또한 상하이 및 닝보와는 약탈적 관계, 톈진과 순수경쟁관계, 그리고 칭다오 및 다롄과 윈윈관계를 형성하고 있다. 전체적으로 2007년 대비 2014년에는 광양항과 동북아 항만들간에 약탈적관계로 변화된 항만이 늘어나고 있다. 이에 대한 광양항의 대응전략은 약탈적 및 경쟁 관계의 항만들과는 협력적관계로, 그리고 윈윈 협력관계의 항만들과는 윈윈관계를 지속하는 전략을 구사할 필요가 있다.

The purpose of this research is to suggest the activation plan of Busan port. In the past years, Busan port enjoyed the golden days because of the China's rapid economic growth. But China's continuous development of ports, the trend of increasing container ship size and increasing direct call to China are coming threats to Busan port. So Korea needs to revise the 'Northeast Logistics Hub' strategy because it is considered that Korea ports continuously will handle China's transshipment cargoes. But now China's transshipment cargo share has decreased by direct call to China ports. It means that China has a lot of its local cargoes, so many ship companies change liner service route to handle China cargoes except Bussan ports although Busan port is included in the main trunk route. In the future, Bussan port will not be able to compete again about throughput with China ports if Busan port's transshipment cargo share decreases. So we must find out and develop Busan port's strength which is the competitive edge. By good luck, Busan port has a few opportunities such as the developed feeder network service and geographical advantages. Busan port has many feeder network service like spider's web in any northeast countries so we can suggest that if Japanese shippers use Busan port to distribute their cargoes to Japanese local areas, its transport costs are cheaper than when they use Japan's main ports. In this paper analyzed side of cost when they use Bussan port like hub to distribute their cargo to their local areas. Because most companies tried to reduce the total cost about logistics. Finally, this paper suggests when northeast shippers(China, Japan) use Bussan port which is more economical than their local main ports.

본 연구의 목적은 미국항만과 동북아시아 항만에 대해 효율성을 비교하여 효율적인 항만이 되기 위한 주요 전략을 제시하는 것으로, 동북아시아 항만을 DEA모형에 적용하였다. DEA모형은 선형계획법에 근거하여 일반적으로 생산 가능집합에 적용되는 몇가지의 공준을 가지고 평가대상의 경험적인 투입요소와 산출물간의 자료를 이용하여 경험적, 효율적 프론티어를 도출한 후 평가대상들이 효율성 프론티어상에서 얼마나 떨어져 있는지의 여부로써 비효율성을 측정한다. 이 방법은 다양한 산출물과 여러 가지 투입요소를 동시에 고려하여 상대적 효율성 값을 도출하여 그 과정에서 각각의 산출물 또는 투입요소에 대해 미리 결정된 가중치를 필요로 하지 않을 뿐 아니라 비효율성이 어느 부문에서 발생하며 그 크기가 얼마 정도인지에 대한 수치적 정보를 제공해줌으로써 경영자가 효율성을 제고하는데 실제적인 도움을 줄 수 있다. 본 연구에서는 DEA-CCR모형, DEA-BCC모형 및 규모효율성을 통해 2005년${\sim}$ 2007년도 미국과 동북아시아 35개 항만에 대해 상대적 효율성을 분석하였다. 연구의 결과에 의하면 미국의 경우 휴스톤항이 효율적으로 나타난 반면 대부분의 항이 비효율적인 것으로 식별되었으며, 한국 및 일본의 항만도 비효율적인 것으로 나타났다. 반면 중국의 경우 상해, 홍콩, 선전 항 등 다수의 항만들이 양호한 것으로 나타나 이에 대한 심층적 분석이 필요할 것으로 사료된다.

China has increased 10 percent every year since 1978. In particular, development and growth of Chinese ports make a remarkable in that the marine and coastal transportation handles the 90 percent of export-import cargo. This growth is beginning to threaten Korea's ports which are striving to become the hub of Northeast Asia logistics. Furthermore, the hub strategy of Northeast Asia is closely related to transshipment cargo invitation. The results of documents research indicate Busan and Gwangyang ports play an important role as an intermediate stopover between China and America. The ways to achieve transshipment cargo invitation are the construction of transshipment system based on the supply chain between korea and china, the maximization of trading volumes creation, equipment of ports infrastructure, and the constructions of the rail, road, coastal transportation infrastructures.

글로벌 생산네트워크의 변화로 인해 우리나라 주요 항만은 새로운 전략의 수립이 요구되고 있다. 무역 패턴의 변화로 인해 중국, 일본, 한국을 포함한 아시아의 경제적 성장이 급속히 이루어지고 있는 상황에서 동북아에 집중되는 항만 물동량을 흡수하기 위해 우리나라 중심 항만들의 환적기능 강화가 필요한 시점이다. 특히 동북아 포트얼라이언스를 활용한 환적기능 강화는 변화하는 무역환경에서 우리 중심항만들이 경쟁력 확보를 위한 기회가 될 수 있을 것이다. 따라서, 본 연구의 목적은 부산항과 광양항 같은 우리나라 주요 항만들의 환적기능을 촉진하기 위한 포트얼라이언스 전략을 제안하고자 하는 것이다. 두 주요 항만의 물류비즈니스 모델 수립을 위해 동북아 포트얼라이언스의 방향과 중국과 일본의 후보 항만들을 제시하였다.

Recently, the change of shipping and port environment has required the new strategy from the liners, terminal operators, ports. The ports of call in the North American and European line also has changed as the Chinese ports made rapid advance. This seems to result from the fact that the trend of the container transportation by sea has developed the traditional concept, called port-to-port system that directly links between a port and another port into the network with complicated hierarchical structure reflecting costs, efficiency, and strategy of the Mega Carrier. This paper suggests the factors for Busan port to become the hub port of northeast Asia by analyzing the change of the liners' strategy along the change of the shipping and port environment, the global management of the operator of container port, and the amount of containers flowing in the northeast Asia.

East Asia has played an important role in the economic and social development in the Asian pacific region and in the global arena. In the region the impact of companies centralizing their logistics activities around a few distribution centers has already led some leading ports such as Singapore, Hong Kong to transform and expand their functions and business activities to provide port users with value added logistics services. Other ports in the region also have an important part to play in the total logistics Chain. In these environments, the maritime activities of Jang BoGo, who was the maritime king of the commercial maritime empire in East Asia in the 9th century, give many implications to the international logistics network strategy that Korea has to take in order to become a power of International Logistics. Though the trading and economic environments at that time may be quite different from today, the super-national maritime management pattern that Jang Bo-go, founder of the Northeast Asian maritime trading kingdom devised, gives us many implications in the global trading and economic environments, in the respects of overseas direct investment and international logistics. Accordingly, the paper aims to examine the establishment of hub port in Northeast Asia, modelled after the maritime network management strategy of Jang BoGo.

This paper tries to draw some implications for Korean seaports in terms of management and development of ports with respect to attracting more transshipment container cargoes. For this the results of the Origin-Destination(O-D) analysis between major Korean ports and top 20 Chinese ports were presented. They also contained the O-D analysis between Chinese major ports and their inland hinterlands.
