최근 세계경기 침체 여파로 전국 항만의 물동량이 감소하는 가운데 인천항의 물동량 또한 증가율이 2007년 20.8%에서 2008년 2.0%로 급격하게 둔화되었으며 2009년도 1/4분기(1-3월)전체 물동량은 309,930백 톤으로 전년동기(379,540백 톤)보다 18.3% 감소하였다. 이에 항만당국은 경기침체와 같은 대외환경의 변화와 주변항만의 적극적인 물량 유치를 위하여 인센티브 정책을 개편하는 등의 전략을 마련하고 있다. 따라서 본 논문은 국내 주요항만의 인센티브 정책을 분석하고 그 시사점을 제시하는 것을 목적으로 한다.

This study investigates the difference of behavioral patterns between the import container volume of all ports and that of Gwangyang port in Korea. All series span the period January 1999 to December 2008. I first test whether the series are stationary or not. I can reject the null hypothesis of a unit root in each of the level variables and of a unit root for the residuals from the cointegration at the 5 percent significance level. I hitherto make use of variance decompositions and impulse response functions, both of which have now been widely used to examine how much movement in one variable can be explained by innovations in different variables and how rapidly these fluctuations in one variable can be transmitted to another. The variance decompositions for the import container volume show that the proportions of the forecast error variance of import container volumes explained by themselves are 30 and 26 per cent after 12 months, respectively. As a result, innovations in exchange rate and business activity explain 70 and 74 per cent of the variance in the import container volume. All in all, innovation accounting indicates that import container volumes are not exogenous with respect to exchange rate and business activity. The impulse responses indicate that container volumes decrease sharply to the shocks in exchange rate and decay very slowly to its pre-shock level, while container volumes respond positively to the shocks in the business activity and disappear very slowly, showing that the shocks last very long. Furthermore Gwangyang port is more sensitive to the change of the exchange rate and the industrial production than all ports.

Lately most Asian countries have tried to develop their ports into a hub port in their region. However, only a few studies examined the theoretical rationale for hub port strategy. Thus, this paper aim to identify the effectiveness of hub port development strategy in global and regional perspectives, respectively. For this aim, the paper conducts regression analysis on the relationship between port size and growth ad calculates the Hirshman-Herfindahal Index on Asian container ports. According to the empirical results, larger ports have grown faster than smaller ports in the world container ports und European/North American ports. However, in the case of the Asian container ports, the result was opposite. And port concentration in Northeast Asian ports is decreasing gradually during the last two decades. Consequently, the effectiveness of hub port development strategy was not very strong in Northeast Asian region.

This paper presents results of a study for development and application of container massive transportation system. The system is aimed to improve competing power of Korean container ports. This paper selects Double stack Multi-Trailer System (DMTS) under consideration of pros-con analysis between three systems alternatives as well as operation process of existing Korean container terminal companies. An analysis of turning radius is undertaken for applying the system. Key elementary technologies was derived by patent analysis. DMTS has no problems in utilization to existing Korean container ports. Further, the system is expected to highly potential to improve operational efficiency in the container ports thanks to its high unit transportation capacity.

우리나라의 항만은 수 출입화물의 99.5%를 처리하며, 육로 및 철도 수송 물동량의 기종점 역할을 수행하는 중요한 곳으로서 항만 물동량의 신속한 처리와 자동화 시스템에 의한 비용절감은 엄청난 효과를 가져온다. 따라서 본 논문에서는 항만에서 취급하는 컨테이너를 자동으로 식별할 수 있는 자동화 방법을 제안한다. 실제 컨테이너 영상을 그레이 영상으로 변환한 후, 프리윗 마스크(Prewitt-Mask)를 적용하여 윤곽선을 추출하고 컨테이너를 식별할 수 있는 개별 식별자의 형태학적 특징 정보를 이용하여 식별자 후보영역을 검출한다. 검출된 식별자 후보영역은 개별 식별자 영역외에 잡음 영역이 포함되어 있으므로 4방향 윤곽선 추적 알고리즘과 Grassfire 알고리즘을 적용하여 잡음을 제거하고 개별 식별자들을 각각 객체화한다. 잡음이 제거된 식별자 후보 영역에서 객체화 한 개별 식별자는 컨테이너 식별을 위해 FCM 기반 퍼지 RBF 네트워크를 적용하여 인식한다. 본 논문에서 제안한 컨테이너 식별자 인식 방법의 성능을 평가하기 위해 실제 컨테이너 영상 300장을 대상으로 실험한 결과, 기존의 방법보다 인식 성능이 개선되었음을 확인할 수 있었다.

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.

Many studies on port tariff have been done over twenty years using publicly assessed data on tariff. Public data for tariff rates do not reflect, however, the port tariff in a real market, since the cargo handling charge, which is the important fraction of port tariff, is confidentially decided by the negotiations between a shipping company and a container terminal operator. In this paper, we collected the real price data of the port tariff on the world major sixteen container ports from a global shipping company and transformed it into the tariff per TEU(US$/TEU). The comparative analysis of port tariff was performed using the port tariff per TEU, and a panel regression analysis was done to identify the relations between the port tariff and demand variables: throughput, GDP and trade amount.

The aim of this paper is to make projection of the demand for export loaded container throughput originating at Incheon port in Korea over the period in question. Systematic analysis is used as a forecasting method instead of quantitative analysis. First of all, the method explores coincident indicators which may reflect the square measure of neighboring industrial complexes which originate/destinate general cargo in export traffic trends. It is noted that in terms of the export loaded container throughput, per unit production scale is intermediated transforming from square measure of production facilities to freight weight in Korea. Consequently, the future progress of the volume can be anticipated relying on the development schemes for developing square measure out of the total square of the industrial complexes. Thus, moving-into percentage of the industrial complexes, percentage of business categories, percentage of capacity and percentage of passing through via Incheon port are adopted and the future traffic demand is projected taking advantage of them.
