This paper unveils the strong competition in container cargo between Hong Kong Port which has been emerging as an international maritime center since the 1970s and Shenzhen Port which has recently gained remarkable achievements in the Pearl River Delta region. Among various competing strategies, the study focuses on the long-term one in which two ports will decide to compete by investing in capacity. The purpose of this research is to examine their decision, making process and to suggest future strategic actions in the current situation. Within its scope, only economic profit brought back from the investment is considered. For this reason, an uncertain payoff two-person game model is developed where an uncertain factor of demand is involved. In applying Uncertainty theory (Liu, 2013), the two methods to solve the game are introduced, including uncertain statistics and the expected Nash Equilibrium strategy. The results obtained from this research generate meaningful suggestions for future competition plan for the two selected ports, which conclude that Shenzhen is the dominant port in this long-term strategy. Compared to existing works on the same topic, the paper shows its distinctiveness by studying the latest competitive situation with regard to the uncertain demand in the game model.

Ningbo Port develops quickly in recent years and with the combination of Ningbo Port and Zhoushan Port, it becomes another important port in the Shanghai International Shipping center. Competition between the two biggest ports in this area can't be avoided. The goal of this paper is investigating the competence of port from two angles, which are spatial structure of the ports cluster and neighboring ports' attraction to cargoes at conjunct hinterlands. The paper firstly uses the HHI index model and shift-share method to qualitatively and quantitatively analyze the data of container throughputs of ports in the shipping center, in order that investigates the spatial structure of ports cluster. Basing on above researches, the paper employs the location quotient to study Shanghai port and Ningbo port's hinterland distributions at Zhejiang province. The conclusion of this study:(I)the ports cluster of the Shanghai International Shipping Center is highly centralized, and undergoes a porcess of first centralization then decentralization since the mid of 90s, last century. (2)Hinterlands of Shanghai port includes: Hangzhou, Jiaxing, Huzhou and Quzhou districts; Hinterlands of Ningbo port includes: Ningbo, Taizhou and Zhoushan districts.

세계 제조 산업의 국제 분업화는 아시아 지역 특히, 동북아 컨테이너 시장의 성장을 주도하고 있다. 이와 더불어 항만산업의 대외적인 환경도 변화하고 있는데, 글로벌 선사 및 터미널 운영사는 대형 M&A 통해 시장 점유율과 지배력을 강화하고 아시아 지역으로의 진출을 가속화하고 있다. 동북아 지역은 이러한 환경변화와 중국항만의 성장으로 그 경쟁이 심화되고 있으며, 부산항은 성장률과 점유율이 지속적으로 감소하고 있다. 따라서 본 논문에서는 동북아 지역의 항만 집중도 변화과정을 살펴보고, 부산항이 지역내 경쟁에서 어떠한 위치를 차지하고 있는지를 분석하였다. 분석결과 부산항의 경쟁적 포지션은 지속적으로 약화되고, 많은 물동량이 경쟁항만에 빼앗긴 것으로 나타났으며, 이를 기반으로 지속 가능한 경쟁력 확보를 위한 글로벌화 전략을 제시하였다.

The maritime logistics environment including seaborne trade, shipping and ports is changing rapidly and continuously. Large containerships, mega carriers and global terminal operators try to achieve economies of scale and economies of scope. As a result of the changing environment, the competition between ports to achieve competitiveness is intensive. Port competition among China, Japan and Korea is becoming fiercer, both directly and indirectly, resulting from the increased trade in northeast Asia. Port development projects within each country stimulate more intensive port competition. As a result, overcapacity, fierce price competition and overlapping hinterland problems will be caused in the future. Co-operation for survival is considered as a strategy in order to solve anticipated problems caused by port competition Busan port, for instance, could co-operate with China and Japan as well as with other ports in Korea Terminal operators' expansion through investments including joint-ventures will make connections between ports smoother. At the port authority level, continuous cooperative interchange between countries is indispensable.

국제교역량이 증가함에 따라 이의 핵심적 요소인 항만의 중요성이 증대되고 있으며, 주요 항만들의 경쟁 역시 심화되고 있다. 항만 경쟁의 궁극적 목적은 물동량 확보라 볼 수 있으며, 항만 관리 운영주체들간 물동량 확보를 위한 치열한 경쟁이 이루어지고 있다. 또한, 해운 항만시장과 물류시스템의 발전 등으로 인하여 항만 구성주체들의 전문화, 분업화 또는 통합화되는 과정 등을 통해 경쟁구조 또한 여러 형태로 나타나고 있다. 이에 항만 관리 운영 주체들의 발전형태에 따른 항만 경쟁구조 변화에 대한 분석이 본 연구의 목적이라 할 수 있다. 연구 결과, 항만의 경쟁구조는 국가간 경쟁, 항만간 경쟁, 컨테이너 터미널운영사간 경쟁, 글로벌터미널운영사의 경쟁 그리고 선사 운영 터미널운영업체의 경쟁과 같이 크게 다섯 가지 형태로 나타났다. 한편, 이들 경쟁주체들은 전략적 차원에서 경쟁이 아닌 협력관계를 부분적으로 보이고 있음을 알 수 있었다.

세계 경제, 해운 그리고 항만의 환경변화에 능동적으로 대응하기 위해 세계 주요 항만들은 경쟁력 제고에 집중하고 있다. 하지만, 기존의 항만경쟁요인과 관련된 연구들은 주로 항만간 경쟁요인을 분석하는데 연구의 초점을 두었다. 이에 본 연구는 항만 경쟁력 재고를 위해 중앙정부, 항만당국, 터미널 운영사, 선사, 기타기관 등 항만 구성원과 항만선택 요인들간의 관련성을 분석하여 각 구성원들의 특성에 맞는 항만마케팅 전략과 경쟁력 제고방안을 수립하는데 그 목적을 두었다. 우선, 해운 항만시장의 환경변화를 검토하여 이러한 환경변화에 대응하기 위한 항만선택 결정요인들을 검토하였고, 이를 토대로 항만을 구성하고 있는 항만경쟁주체들과 항만경쟁 요인들간의 관련성을 분석하였다. 하지만 비용, 서비스, 시설 등의 측면에서는 항만당국과 터미널 운영사 등에서 관련성이 높게 나타났는데, 이는 선사 유치를 위하여 항만당국들이 제시하는 인센티브 등 제도적 측면에서의 지원과 항만의 직접적인 운영과 관련한 터미널 운영사라는 측면이 부합된 결과라 할 수 있겠다. 그러나 항만당국과 터미널 운영사 외 다른 주체들 역시 각각의 속성에 따라 관련성이 높은 요인들을 도출할 수 있었으며, 이러한 요인들을 토대로 항만경쟁주체들간의 항만마케팅 전략 수립이 가능할 것으로 판단된다.

Although the ports are actually competing with various strategies, the definition and structural understanding of port competitive power are not known very much. Therefore this study has launched from this fact, and has the objective of obtaining the structural model of the competitive power, and understanding the components of the port competitive power. The following are the results of the study. First, the process began by abstracting the components that composed the port competitive power through recent research, and grouping it by the most core components using the KJ method. Also, by using the FSM(Fuzzy Structural Modeling) method to understand the structure of the grouped components, and the structural model of the port competitive power was able to obtain as the result. Second, when analyzing the obtained structural model, port expenses, main trunk location, port congestion and port facility came out to be the most important component groups, and especially port expenses was the most effective component that effected all the other components overall. Third, the component groups that were relatively less important, effected by most of the other components, and located on the top level of the structure model were the hinterland accessibility, port ownership, customs duties speed, and large ship port entrance possibility etc. Fourth, the results of this study will be able to be used when establishing competing strategies for our country's ports by proposing the relatively important components with the port competitive rower considered.

Although many studies on modelling of port competitive situation have been conducted, both theoretical frame and methodology are still very weak. In this study, therefore, a new algorithm called ESD (Extensional System Dynamics) for the evaluation of port competition was presented, and applied to simulate port systems in northeast asia. The detailed objectives of this paper are to develop Unit fort Model by using SD(System Dynamics) method; to develop Competitive Port Model by ESD method; to perform sensitivity analysis by altering parameters, and to propose port development strategies. For these the algorithm for the evaluation of part's competition was developed in two steps. Firstly, SD method was adopted to develop the Unit Port models, and secondly HFP(Hierarchical Fuzzy Process) method was introduced to expand previous SD method. The proposed models were then developed and applied to the five ports - Pusan, Kobe, Yokohama, Kaoshiung, Keelung - with real data on each ports, and several findings were derived. Firstly, the extraction of factors for Unit Port was accomplished by consultation of experts such as research worker, professor, research fellows related to harbor, and expert group, and finally, five factor groups - location, facility, service, cargo volumes, and port charge - were obtained. Secondly, system's structure consisting of feedback loop was found easily by location of representative and detailed factors on keyword network of STGB map. Using these keyword network, feedback loop was found. Thirdly, for the target year of 2003, the simulation for Pusan port revealed that liner's number would be increased from 829 ships to 1,450 ships and container cargo volumes increased from 4.56 million TEU to 7.74 million TEU. It also revealed that because of increased liners and container cargo volumes, length of berth should be expanded from 2,162m to 4,729m. This berth expansion was resulted in the decrease of congested ship's number from 97 to 11. It was also found that port's charge had a fluctuation. Results of simulation for Kobe, Yokohama, Kaoshiung, Keelung in northeast asia were also acquired. Finally, the inter port competition models developed by ESB method were used to simulate container cargo volumes for Pusan port. The results revealed that under competitive situation container cargo volume was smaller than non-competitive situation, which means Pusan port is lack of competitive power to other ports. Developed models in this study were then applied to estimate change of container cargo volumes in competitive relation by altering several parameters. And, the results were found to be very helpful for port mangers who are in charge of planning of port development.

The evaluation of port competition could be applied to determining the selection of a calling port. A few fundemental attributes of port competition were adapted by the 'brian storming'method. The criteria used for evaluating a port's competitiveness were as follows : efficiency of port operations, competitive power of each port's industry, economic activity of the hinderland associated with each port and capability of globalization. The weight of each criterion was 30%, 40%, 20% & 10%, respectively. And the most important factors that were considered in choosing each of the above criteria were profitability, port information system, cargo volume & inducement of foreign capital. The results of this study seemed to suggest that factors which influence port competition varied according to port circumstances, such as computer and communication systems and access to the global trade within the World Trade Organization.

Technological and organisational changes in transport system have introduced new dimension into port system development and inter-port competition. The quality of service now required by the customer is costly and not easily provided by small shipping companies and small ports. It has been suggested that in the future container shipping may be concentrated by space-sharing arrangements or actual mergers into the hands of a few mega-operators with the investment potential to provide total logistics networks. In order to compete effectively, high load factors will be essential and port concentration inevitable. A fa-voured few ports will become the load centres and other ports will assume a secondary feeder role. In this study, three questions are raised and attempts are made to answer them : (a) what is the new role of ports today ; (b) why should ports be engaged in this new role ; and (c) how can ports play this new role. In short, a modern port should be a service centre and a logistic platform for international trade and transport-a third generation port. Ports, in particular, have to make every effort to be competitive in the cost and quality of services and to make the port a transport and distribution service centre. For most ports, this is not an option but a must ; an essential requirement for survival in this win or lose situation. The best way to win is to maintain a close contact with port users, listen to them, discuss with them, help them and satisfy them. That is port marketing. Starting from the findings of port marketing, it is es-sential to work out appropriate development plans and marketing targets and to improve port competitive-ness. As an alternative method, a port competitiveness model is suggested, which may help port managers to make appropriate improvements.
