This study examines the competitiveness and cooperativeness among the container ports in East Asia by analyzing their monthly dynamics in eight years (2008-2015). Time series data on container throughput divided into origin and destination (O/D), such as the top six Chinese ports and the transshipment (T/S) ports such as Hong Kong, Busan, and Singapore, are computed with two methods based on the Vector Error Correction Model (VECM). The first Granger causality test results show that Busan T/S has significant bilateral relations with three Chinese O/D ports; and significant unidirectional relations with three other O/D ports. Shenzhen port has significant bilateral relations with Singapore, and has a significant unidirectional relation with Hong Kong port. Co-integrating test results showed that Busan holds negative co-integration with all Chinese O/D ports. Impulse response function (IRF) results show an opposite direction between paired ports. The ratios of the impulse from T/S ports are significantly high to one another in the short-run, but its power declines as time passes. The ratio of the impulse from the Chinese ports to T/S ports is less significant in the short-run period, however, it becomes more significant as time passes. The significance of most shocks was high in the second period, but was diluted after the sixth period.

본 연구의 목적은 지난 20년 간 세계 컨테이너항만들을 대상으로 항만집중도 및 항만규모와 성장간 상관관계를 분석해 봄으로써 현재 우리나라가 추진하고 있는 중심항만 개발전략에 대한 시사점을 제시하는 데 있다. 이를 위해 아시아 21개 항만의 허쉬만-허핀달지수를 구하였으며, 세계 50대 컨테이너 항만뿐만 아니라 유럽, 북미 그리고 아시아지역 컨테이너항만들을 대상으로 항만규모와 성장간 실증분석을 시도하였다. 그 결과 아시아 컨테이너항만의 물동량 집중도는 90년대 중반 이후 둔화되고 있으며 동북아지역 항만집중도가 다른 지역에 비해 상대적으로 낮은 것으로 나타났다. 항만규모와 성장간 관계에 있어서도 세계 및 유럽 항만들은 대형항만일수록 성장률이 높았던 것으로 나타난 반면, 아시아지역 컨테이너 항만들은 소형항만들의 성장률이 더 높았던 것으로 분석되었다.

This study was intended to analyze the effect of port decentralization on port management and port development, analyze whether port site centrality has mediated effect in relation between port decentralization and port management and port development. This study surveyed public officials and researchers who plan and execute port policies, and analyzed the influence relationship of variables and the mediating effect using multiple regression analysis. Results are as follows, First, it was analyzed that the port authority decentralization and regional-centered port policy have a positive influence on the port site centrality, and the port authority decentralization has a positive influence on port management and port development. Second, the port site centrality was confirmed to have a positive influence on port management and port development. Third, port site centrality was shown to mediate the relationship between port decentralization and port management and port development. This study suggested the positive effect of port decentralization to local government on efficient port management and port development, and the need to draw up port site-oriented policies.

세계의 주요 자원중 하나인 원유는 산업의 가장 기초적인 부분을 담당하고 있다. 대한민국은 대표적인 원유수입국이며 원유 자원 등을 수입을 하지 못한다면 내수 및 가공후 수출에 큰 위험으로 다가온다. 그렇기에 원유 수입 등의 액체화물 수입이 필수적이다. 차별성을 두기위해 액체화물 항만간의 경쟁을 확인하고자 울산, 대산, 여수광양항을 선정하였다. 항만들은 석유화학단지를 보유하고 있는 항만이며 원유는 수입후 정제를 통해 석유정제품, 화학생산공업품의 물품을 생산한다. 시계열 데이터를 이용한 VAR 모형을 이용하였다. 이를 수행하기 위해 단위근 검정을 실시하였으며 토다 야마모토 인과 검정을 통한 항만간의 관계를 확인하였다.

This study formulates a development strategy for Gwangyang port through the analysis of its competition with other major Northeast Asian ports. A revised BCG matrix is applied to estimate the change in competition between the major ports in Northeast Asia and the Lotka-Volterra model is used for the competitor analysis. The growing competitive power and influence of Chinese ports, continued competitive advantage of Busan port, diminishing competitiveness of Gwangyang and Incheon ports, and disappearing competitive position of Japanese ports in Northeast Asia are all confirmed. In addition, according to the relationship between Gwangyang port and other major Northeast Asian ports from 2007 to 2014, Gwangyang port has changed to a predatory from a win/win relation with Busan port and has maintained its predatory relationship with Hong Kong port in terms of transshipment cargoes. Moreover, Gwangyang port has formed predatory relationships with Shanghai and Ningbo ports, a pure competitive relation with Tianjin port, and a win/win relation with Qingdao and Dalian ports. Overall, predatory relationships between Gwangyang port and other Northeast Asia ports increased from 2007 to 2014. The counterstrategies for Gwangyang port to address this situation include establishing cooperative relations and continuing the win/win relationships with cooperative ports.

This paper analyzes the effects of port size on port tariff using the data for world major sixteen container ports. Some previous studies show that demand for port services have significant effects on port tariff, but we cannot find studies analyzing the correlation between the supply variables and the port tariff. In this paper, we used the five supply variables, which are the number of gantry crane, the number of berth, the quay length, the terminal area and the storage capacity for containers. The panel regression results are as follows. Port tariff generally decreases as port size increases, which shows that port tariff is explained by the economic theory. However, increase of port size, in some cases, does not reduce port tariffs, which may be due to monopolistic characteristics of port. This paper also shows that both demand and supply factors affect port tariff, but that demand factors have more consistent effect on port tariff than supply factors.

Based on the review of the existing studies, this study built the conceptual framework describing the structural relationships among port service quality dimensions(port internal service quality, external service quality, interaction quality), customer satisfaction, customer trust and customer loyalty. In specific, switching barrier was included as moderator in customer satisfaction and customer loyalty relationships. The subjects are the customers who use the Busan New Port. A survey using 317 customers was conducted, Confirmatory factor analysis was conducted to test the validity of the measurement model, and AMOS analysis approach was used to gain important insights into how customer retention in the port business can be ensured. Results in this paper indicate that customer trust and satisfaction are identified as antecedents of the port service quality dimensions. Customer satisfaction positively influences trust. Customer trust and satisfaction positively influence loyalty. Switching barrier positively moderates the relationship of customer satisfaction and customer loyalty. Finally, this study suggests that the implications of these findings and offers directions for future research.

The purpose of this study is to examine the causuality among export and import trading volume of port of Busan, Kwangyang, Incheon and to induce policy implications. In order to test whether time series data is stationary and the model is fitness or not, we put in operation unit root test, cointegration test. And We apply Granger causality and impulse response and variance decomposition based on VECM. The results indicate that the trading volume of port of Busan is not largely influenced by that of port of Kawangyang and Incheon, but the trading volume of port of Kawangyang and Incheon is largely influenced by other ports including port of Busan. The result suggest that government has to focus on policy that the port of Kawangyang and Incheon can raise its own competitiveness in the world market.

The conventional methods of container forecasting is done through regression methods based on GNP growth trends and by other forecasting methods proposed by several authors. However these efforts prove to be inadequate with visible weakness and a more reasonable approach need to be determined. The succeeding sections elaborate the methodology and approach adopted. The results are then compared through a case study involving the forecast figures derived by the Pusan Port Authority and the values obtained by MRCS model introduced in this paper.
