The purpose of this paper is to analyze the concentration effect of Busan container terminal. Productivity and efficiency have played key role to attract more cargo to a port because these are important factors to select liners’ calling port in vessel deployment. It means that productivity directly links with the liners’ vessel operation cost. The main results of this paper are as follows: the port concentration by terminal integration can improve the port's external image with recovering tariff competitiveness and also facilitate economic effect of size through efficient management.

The purpose of this paper is to analyze the trend on scale efficiency of the Port of Gwangyang from 1994 to 2004 using CCR, BCC, and Malmquist index approaches. The main results are as follows. first, scale efficiency shows a 50% similar [5(94/95, 95/96, 97/98, 2001/2002, 2003/2004) out of 10] pattern to technical efficiency change. Second, total factor productivity increased at 48.57% rate of growth on average in 6 out of 10 periods except 96/97, 97/98, 99/2000, and 2000/2001. 2003/2004 period is the one period experiencing rapid total factor productivity changes, mainly due to technical progress. Third, the ranking order of accumulative indices is scale efficiency change, TFP change, efficiency change, technical change, and pure efficiency change. The main policy implication of this paper is that according to the CCR, BCC, and Malmquist results, the Port of Gwangyang should develop the plan for enhancing the 5 Malmquist indices with following the management way of benchmarking ports.

현재 정부는 우리나라 물동량 증가에 따른 수도권 항만의 기능 재정립 및 신항만 입지를 선정하기 위한 조사·연구를 진행중이다. 본 연구에서는 현행 인천항의 항만 시스템과 신규항만 시스템에 대한 컴퓨터 시뮬레이션 모형을 개발하여 신항만 개발로 인한 선박대기시간의 감소 및 항만 체류 시간의 감소 등을 예측하였다. 이 결과는 신항만 개발의 경제적 타당성 분석에서 사용자 편익으로 활용될 수 있다. 시뮬레이션 모형은 ARENA를 이용하여 개발하였다. 수도권 항만 즉 인천항에서 처리되는 화물은 양곡을 비롯한 12개 품목이며, 각각의 화물은 5단계의 규모별로 나누어 선박의 도착간격 및 재항시간 분포 등을 1995년 인천항의 실제 자료를 토대로 추정하였다. 선박의 도착간격은 지수 분포로 나타났으며, 서비스시간은 삼각분포(Triangular Distribution)로 근사되었다. 화물량 예측치가 1996, 2001, 2006, 2011, 2020년으로 되어 있고, 이에 따른 신항만 입지 및 규모가 결정됨에 따라 각 연도별로 신항만을 개발할 경우와 개발하지 않은 경우의 각각에 대한 연간 화물별 선박대기 시간 및 재항시간 등을 추정하였다.

This study mainly investigates the port SOC's impact on trade volume. In order to investigate the relationships between port SOC and trade volume, we did the empirical analysis using panel data regression and fixed effects model. The total period of 97 years and 1,082 ports' information were applied to panel data and regression model. According to the results, the coefficients of development of container berth, development of bulk berth, maintenance of port, the jetty facilities like breakwater have positive(+) impact on the dependent variable, the trade volume. Especially, the jetty facilities show a strongly positive impact on trade volume. On the other hand, the development of new port and navigation facilities like lighthouse have a negative(-) impact. In examining Hausman test and LR test, the fixed effect model is statistically more appropriate than the random effect model for this study.

Port distripark can activate more functions. It is adjacent to a port. However, domestic port distripark is still limited to support port because of the shortage of infrastructure facilities, government policy, and investment. Therefore, this study tried to investigate the operation status of domestic port distripark and derive policy implications by conducting DEA analysis and productivity analysis based on internal data of each port distripark. As a result of Data Envelopment analysis, it was found that the west port distripark of Gwangwang and the northern port distripark of Incheon were efficient in the warehouse industry while the northern port distripark of Incheon and the Ulsan 1 port distripark were efficient in the manufacturing industry. In addition, in the case of foreign investment productivity, the west side port distripark of Gwangyang and the stage 1 port distripark of Pyeongtaek Dangjin were found to be higher than the others. In the case of facility investment productivity, the port distripark on the west side of Gwangyang and the north side of Incheon had the highest productivity. Lastly, in the case of labor productivity, the north side of Incheon and Busan ungdong port distripark showed the highest productivity. These results imply that it is important to review handling item when picking up enterprises in the port distripark for enhancing efficiency, foreign investment, and facility investment. The number of employees is not directly affecting the productivity improvement.

Large scaled railway freight transportation facilities in harbors are located in Busan port and Gwangyang port. The port rail depot plays an important role as the departure and destination function of railway logistics. However, presently, it is not relatively vitalized because it is not reflect the railway freight transportation's characteristics such as scale of railway tracks or yards area. In addition, even if port rail depot is vitalized, processing capacity is already saturated. Therefore, it is difficult to increase rail transport quantity. To activate railway container transportation business, it is very necessary to recalculate the facility size of port rail depots. Focused on the Busan new port rail depot, this paper analyzes the problems of port rail depot facility that has currently opened and finds some alternatives to resolve them.

The 21st Century Maritime Silk Road (MSR) is an important part of Belt and Road Initiative(BRI). As an economic and trade corridor for dozens of countries in Asia, Europe and Africa, and the port as an important link node, the efficiency of port operation directly affects the implementation of BRI's strategy. On the basis of combining BRI and related evaluation methods of port efficiency, this paper uses DEA-BCC model to select port production berth number and production berth length as input index container throughput and cargo throughput as output index to analyze the port efficiency of 14 ports in China. The results show that: (1) The overall efficiency level of the ports along the MSR is relatively low. Most of the ports have not reached the DEA efficiency and there are different degrees of problems in scale investment and technological improvement. However, this situation is accompanied by the implementation of China's maritime cooperation strategy and becoming better year by year. (2) The low operating efficiency of ports along China's MSR is mainly due to the lack of coordination between scale efficiency and technical efficiency, which is caused by insufficient scale investment in the port itself, weak economic linkage between the hinterland and the port, (3) Whether a port has a strong comprehensive strength does not entirely depend on the cargo throughput or scale but also includes the port's operating efficiency.

최근 지자체별로 민간투자에 의한 사회기반시설 확충을 추진하고, 육상의 도로망을 직선화 및 최적화 하기 위해 항만 및 주요 항로를 횡단하는 해상교량 건설이 활발히 추진되고 있다. 하지만 경제적인 측면만을 고려하여 계획함으로써, 장래 항만 발전과 해상교통안전 확보에 지장을 초래할 가능성이 크다. 아울러 장래 항만발전과 항만이용 안전에 미치는 영향이 지대함에도 항만운영 및 해상교통안전 확보관점에서 제시된 해상교량 건설기준이 없어, 교량규모 결정시 이해당사자간 갈등이 반복되고 있는 설정이다. 이에 본 연구에서는 현행 국내 해상교량 건설에 따른 문제점 및 기준설정의 필요성을 사례분석을 통해 제시한다.

The purpose of this study is to estimate total factor productivity(TFP) growth by stochastic frontier function and to grasp contributing factors of its growth rate by decomposing the total factor productivity into efficiency change, technical progress, scale change, and allocation change. Annual growth rate of total factor productivity for 1990-2003 is 0.019 (1.9%), higher than that of overall industry (0.010). The main component of TFP growth is not efficiency change but technical progress. Contributing factors of total factor productivity growth are change of allocation efficiency in port industry, technical progress in sea-transportation industry, and change of scale efficiency in transportation-equipment industry. The change of total factor productivity shows a decreasing trend since late in the 1990s. The annual technical efficiency of port-logistics industry is less than that of overall industry. Capital elasticity for output (0.391) is higher than labor elasticity (0.227), but scale economy of port-logistics industry is 0.618, which is far from optimal scale economy.
