The purpose of this paper is to measure the competition power of administration service in Korean Seaports by using the scores of customer satisfaction for administration service investigated yearly from 2000 to 2003 by Ministry of Maritime Affairs & Fisheries. And also, this paper shows the competition power of Korean seaports in terms of efficiency by using DEA(data envelopment analysis) method after measuring the change of productive efficiency scores subject to including and excluding the scores of customer satisfaction for administration service as output variable. The empirical main results of this paper are as follows: First, the efficiency scores of the Ports of Donghae, Gunsan, Jeju, Yeosu, Masan, and Pohang have worsened if the customer satisfaction score is excluded as output variable. Therefore these ports have been influenced by the score of customer satisfaction more positively. Second, the changes of the ranking order by measuring the average efficiency scores of each ports subject to including and excluding the scores of customer satisfaction for administration service as output variable are as follows: Busan(9-->7), Incheon(6-->6), Yeosu(1-->4), Gwangyang(4-->3), Masan (10-->9), Ulsan(5-->5), Donghae(8-->11), Gusan(12-->12), Mogpo(3-->2), Pohang(11-->10), Jeju(7-->8), Daesan(2-->1).

The steady growth of seaborne trade has resulted in the further development of container ships, ports, and container terminals, and the operating efficiency of a container terminal is a decisive element for its competitive ability in international markets. The aim of this research is to evaluate the relative efficiency of Russian and South Korean container terminals. For this purpose, the output-oriented DEA was applied to 31 container terminals of Russian and South Korean seaports for the years from 2012 to 2014. The results indicate that Korean container terminals exhibited higher efficiency scores than their Russian counterparts.

이 연구는 DEA방식을 사용하여 1997년부터 2006년의 기간에 대하여 한국의 5대 항만의 효율성을 측정하고 아울러 맘퀴스트 생산성지수를 측정하고 비교한다. 규모에 대한 수익불변(CRS)과 규모에 대한 수익가변(VRS)을 가정하여 항만의 효율성수준을 측정한다. 부산이 가장 효율성이 높은 항만으로 측정되었다. 발견된 내용은 다음과 같다. 1)부산항, 인천항, 울산항은 CRS와 VRS에서 효율적인 항만으로 나타났다. 2)광양항은 효율적인 항만에 비하여 4.3%정도 낮은 효율성을 보여 주었다. 3)포항항은 효율적인 항만에 비해 27.3% 낮은 효율성을 보여 주었다. 4)한국의 5대 항만의 총요소생산성은 1997년에서 2006년 사이에 매년 3.1%정도씩 낮아졌다. 몇 가지의 정책함의는 다음과 같다. 1)부산항이 광양항보다 효율적으로 나타났는데 이는 두 지역경제의 경제활동의 차이를 반영하는 것으로 보인다. 2)1997년에서 2007년 사이에 한국의 5대 항만은 전반부의 기간에는 1997년의 한국의 금융위기로 인하여 낮은 효율성 수준을 보여주었으나, 후반부의 기간에는 경제회복으로 더 높은 효율성을 시현하였다. 미래의 연구에서는 더 풍부하고 신뢰성 있는 자료를 활용하여 한국의 항만의 특징을 더 잘 이해하도록 다양한 접근방법이 적용되기를 기대한다.

본 연구의 목적은 동북아시아 주요 컨테이너항만간의 상대적 효율성을 분석함으로써, 각 항만의 현재 효율성 수준을 파악하고, 효율적 항만이 되기 위한 주요 전략수립 방안을 제시하고자 하는 것이다, 동북아시아 지역의 주요 16개 항만을 대상으로 개별항만 효율성 및 상대적 효율성을 분석하였으며, DEA기법을 사용했다. DEA모형 중 규모수익불변모형인 CCR모형과 규모수익가변모형인 BCC모형을 통해 항만 효율성을 분석하며, 또한 CCR모형에 의해 평가된 효율성을 BCC모형에 의해 평가된 효율성으로 나눈 비율인 규모의 효율성 측면에서도 효율성을 분석하였다. 이러한 방법의 실증분석을 시행함에 있어서 투입요소로는 선석 수, 안벽 길이, 수심, 부두 총면적, C/C 대수를 이용하고, 산출요소로는 컨테이너 물동량을 이용했다. 연구 결과, 중국의 경우, 대부분의 항만이 효율적으로 나타난 반면, 한국과 일본의 경우 대체적으로 비효율적인 것으로 나타났다. 특히, 부산항과 상해항, 롄윈강항과 인천항, 다롄항과 광양항이 투입요소가 유사하지만 산출요소인 컨테이너 물동량은 큰 차이가 있는 것으로 나타났다.

Purpose: This study proposed a DEA (Data Envelopment Analysis)-based stepwise benchmarking target selection for inefficient DMU (Decision Making Unit) to improve its efficiency gradually to reach most efficient frontier considering resource (DEA inputs and outputs) improvement preferences. Methods: The proposed method proceeded in two steps. First step evaluates efficiency of DMUs by using DEA, and an evaluated DMU selects benchmarking targets of HCU (Hypothesis Composit Unit) or RU (Real Unit) considering resource improvement preferences. Second step selects stepwise benchmarking targets of the inefficient DMU. To achieve this, this study developed a new DEA model, which can select a benchmarking target of an inefficient DMU in considering inputs or outputs improvement preference, and suggested an algorithm, which can select stepwise benchmarking targets of the inefficient DMU. Results: The proposed method was applied to 34 international ports for validation. In efficiency evaluation, five ports was evaluated as most efficient port, and the remaining 29 ports was evaluated as relative inefficient port. When port 34 was supposed as evaluated DMU, its can select its four stepwise benchmarking targets in assigning the preference weight to inputs (berth length, total area of pier, CFS, number of loading machine) as (0.82, 1.00, 0.41, 0.00). Conclusion: For the validation of the proposed method, it applied to the 34 major ports around the world and selected stepwise benchmarking targets for an inefficient port to improve its efficiency gradually. We can say that the proposed method enables for inefficient DMU to establish more effective and practical benchmarking strategy than the conventional DEA because it considers the resource (inputs or outputs) improvement preference in selecting benchmarking targets gradually.

The efficiency of port operations is an important indicator of port development. Moreover, there is excess handling capacity in Chinese ports, which results in a slower speed of development. Under the detrimental environment of the international shipping market, it is necessary to improve the operation efficiency of ports for long-term development. This paper provides an assessment of the competitiveness of Chinese seaport companies using the Boston Consulting Group's matrix, and efficiency measurements using a data envelopment analysis and the Malmquist method. This analysis showed that highly efficient companies reformed their development strategies, which should be a solution considered by less efficient companies, such as Shenzhen Yan Tian Port Holdings Co., Ltd.. Although, having high throughput should be reformed in the investment structure. This research will assist port companies in gaining effective operating experience, and governments in establishing strategic planning to enhance the efficiency of port development.

항만이나 공항의 소유구조에 대한 효율성 분석은 지금까지 서로 엇갈리는 결과를 제시하고 있다. 즉, 민영화 또는 공영화로 인한 효율성 효과가 자료 또는 분석 방법에 따라서 일치된 결과를 보여주지 않고 있다. 본 논문은 국내의 항만이 포함된 국제 항만 교역데이터베이스를 기반으로 베이지안 확률적 프런티어 모형을 적용하여 항만의 소유 구조에 따른 효율성 분석을 하였다. 소유 구조는 Tongzon과 Heng (2005)의 방법을 따랐으며 제안된 몇 가지 모형과 그들의 모형을 DIC 통계량을 이용하여 비교하였다. 베이지안 추론에 필요한 MCMC 방법은 Griffin과 Steel (2007)에서 소개된 WinBUGS 프로그램을 이용하여 구현하였다.

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.

With development of Asia's economy, the ports in trunk route have increased its handling capacity According to previous studies, main determinants to become hub-port are referred to location, connection inland transport with hinterland, port service availability and efficiency, cost of port handling, socio-economic stability and port information system etc. This study aims to investigate the changes in factors determine port's competitiveness particularly in Asian neighbor ports such as Hong Kong port and Shenzen port, and Singapore port and the Port of Tanjung Pelapas in Malaysia by comparing and analyzing main indicators relating to those ports. In conclusion, main reasons which gained competitiveness by newly developed ports such as Shenzen port and the Port of Tanjung Pelapas were port price and massive hinterland space offered.
