두 국가에 위치한 국내 기업과 외국 기업이 경쟁하는 복점시장에서, 국가의 무역 정책에 따른 항만운영구조(국영화/민영화) 선택 전략을 분석한다. 그리고 항만 운영구조 선택에 따른 각 기업의 이윤, 항만 사용료 수준과 항만의 이윤, 사회후생을 비교분석하고, 자유무역 정책과 관세 정책의 각 균형 비교분석을 통해 최적 전략을 도출한다. 그 결과, (i) 관세 정책에서, 운송비와 상관없이 정부는 항만 국영화를 선택하는 것이 지배전략이다. (ii) 관세 정책에서, 항만은 높은 항만 사용료를 설정하는 민영화 정책의 경우 더 높은 이윤을 달성하며, 국가와 항만의 이해관계 불일치가 발생한다. (iii) 관세 정책과 상관없이 낮은 운송비 수준이라면, 정부는 항만 국영화 선택을 통해 더 높은 후생을 달성하며, 높은 운송비 수준이라면 항만 운영구조(민영화/국영화)에 상관없이 정부는 자유무역 정책의 경우가 더 높은 후생을 달성한다.

All over the world, one finds different types of dues, charges and fees imposed for the use of port facilities. The positiion is further confused by the fact that different names are often used for the same charge in different ports and again the same name can be used for different types of charge. For instance, in some places "tonnage" dues can be dues on cargo tonnage and in others are dues on shipping tonnage. Charges made by port authorities can be of two kinds; charges on ships and charges on goods. One of the abiding complaints of all port tariffs is that they are too complicated. The plea is for simplicity and comprehension. The purpose of this study is to elucidate and to criticize principles for guiding port pricing policy.ng policy.

In port management, the scale of facilities and port layouts are major factors characterizing the port, which influence port economics and productivities continuously through the port operation. Grouping ports in certain region by their characteristics could be used as the principal informations to establish national policy for port development or investment and also to analyze the competitiveness between ports. Currently Korean ports are divided into two groups such as the local port and the designated port containing foreign trade port and coastal port under the Korean port law. These divisions seem to be used for port administration as the matter of convenience but some qualitative grouping is needed for research of port problems. In this paper, 20 major Korean ports were clustered by the similar characteristics using Fuzzy C-Means and found to be classified 8 qualitative groups.

Purpose - As globalization progresses, complexity also increases, and various factors that threaten port functions are emerging. Accordingly, the demand for port security to prevent the crisis and resilience that quickly recovers its original function after the crisis is also increasing in port operations. However, few studies have examined how to ensure the port security and how the resilience affects operation performance of port and sustainability performance as well. So the study aims to find out how port security affects port resilience and port operational performance, and consequently, this two factors affect socioeconomic and environmental sustainability performance respectively and synthetically. Design/methodology - Confirmatory Factor Analysis (CFA) was first performed to determine the validity of the factors of model and hypothesis test was performed using Structural Equation Model (SEM) to analyze the Port Performance Model, which show the perception logic among port security level, port resilience, operation performance, and sustainability performance. In order to empirically analyze this model, total 264 respondents from port security operators, shipping companies in South Korea were surveyed. Findings - As result of SEM, First, port security level positively affected the resilience (H1) and cargo operational performance (H2) but not in both of the sustainability performances (H3, H4). Second, resilience positively affected only cargo operational performance (H5) and socio-economic sustainability performance (H7). Last, cargo operation performance positively affects the both of sustainability performances (H8, H9). Originality/value - It was confirmed that port security could improve cargo operational performance through ensuring port resilience and eventually increase the socio-economic sustainability. Therefore the study implies that careful integration and management of port security, port resilience, and sustainability are required, along with compromise on sustainable development goals in the social, economic, and environmental area among all stakeholders.

In this paper the order picking problem in warehouses is considered, a topic which has received considerable attention from the international academic body in recent years. The order picking problem deals with the retrieval of order items from prespecified locations in the warehouse, and its objective is usually the minimization of travel time or travel distance. Hence, a well-thought order picking policy in combination with an appropriate storage policy will enhance warehouse efficiency and reduce operational costs. This paper starts with a literature overview summarizing approaches to routing order pickers, assigning stock-keeping units to pick locations and designing warehouse layouts. Since the layout design might affect both storage and routing policies, the three factors are interdependent with respect to order picking performance. To test these interdependencies, a simulation experiment was set up, involving two types of warehouse layout, four types of storage policy, five well-known heuristics and five sizes of order picking list. Our results illustrate that from the point of view of order picking distance minimization it is recommended to equip the warehouse with a third cross aisle, although this comes at the cost of a certain space loss. Additionally, we propose a set of most appropriate matches between order picking heuristics and storage policies. Finally, we give some directions for further research and recommend an integrated approach involving all factors that affect warehouse efficiency.

한국 정부가 양항정책(two-port policy)으로 추진하고 있는 부산항과 광양항 개발에 대한 예산의 적정성을 놓고 갈수록 논란이 격화되고 있다. 이런 논란의 중심에는 항만개발이 경제적 논리보다는 대통령 선거, 국회의원 선거, 정권의 지역주의적 특성 등 정치적 논리에 따라 예산투입이 이루어졌다는 문제의식이 자리하고 있다. 선거와 정권의 특성 등 정치적 변수가 특정 항만개발을 위한 예산지출에 중대한 역할을 하였다는 것이다. 본 논문의 목적은 부산항과 광양항 개발 예산에 내재되어 있는 정치적 예산배분을 검증하기 위한 것이다. 부산항과 광양항 개발에 대한 정치적 예산 분석을 위한 정치변수로 선거와 정권을 선택하였다. 분석결과 부산항은 지방선거와 정(+)의 상관관계가 있었고, 광양항 예산은 대선과 상관관계가 존재한 것으로 나타났다. 또한 정권의 지역주의(regionalism)에 따른 항만개발예산의 지출은 이루어지지 않았다. 대신 정권이 표방한 국가의제(national agenda)가 항만개발예산의 집행과 밀접한 관련이 있음을 추론할 수 있다. '동북아 중심정책'을 국가의제로서 가장 적극적으로 추진한 노무현 정권과 전국 항만 및 부산항, 광양항의 상관관계는 비교적 높거나 매우 높은 수준으로 나타났다. 본 논문은 상관관계 분석을 통해 정치적 변수와 항만개발예산이 어떤 상관관계에 있는지를 확인하였으나, 국회의원 선거와 대통령 선거, 정권의 지역주의적 성격은 항만개발에 대한 정부의 의사결정과 계획수립, 사업착수 등에 대해서는 중대한 영향을 주었을 가능성이 높다. 향후 항만개발예산에 대한 심도 있는 계량분석과 함께 사업계획 수립, 공사착수 등 질적 변수를 대상으로 한 후속 연구가 필요할 것으로 본다.

Grouping ports in certain region by their characteristics could be used as the principal informations to establish national policy for port development or investment and also to analyze the competitiveness among ports. Currently Korean ports are divided into two groups such as the local port and the designated Port containing foreign trade port and coastal port under the Korean Port Act. This classification seems to be used for port administration as the matter of convenience but some qualitative grouping is needed for research of port-related matters. The aim of this paper is to cluster 28 foreign trade ports as per the similar characteristics by Hard C-Means and to analyze the results of this clustering.

Recognizing that the main container ports' status is gradually inclining, the Japanese government is driving forward the super hub port project. This project has three goals, unifying Japanese ports separating nationally, diminishing the port costs by 30 percents less than the current port costs of their competitors, and cutting down the lead time of processing import-export freight into 24 hours, Singaporean level. The project will work to some extent, if succeeding, but the effect is doubtful if it will be the fundamental solution of Japanese ports' crisis. I wrote this paper since I thought that this Japanese policy would serve as a good reference of Korea, which had two container ports system and its prospect was not good through the fact that the Busan ports' rank of dealing with containers fell down to the fifth in 2003.

The world of container shipping and container terminal business is changing and container ports need to know what the changes are in order to plan how to respond. In particular, the container transport industry has noticed two major developments such as globalization and consolidation. The purpose of this paper is to review the current trend towards globalization and consolidation of container liner shipping and container terminal business. It also investigates the impact of these market developments on container ports and presents its implications for port development, management and operation, and port competition policy. According to the discussion of this paper a greater exercise of market power of container terminal operators will have negative impacts on international trade and national economy, especially port users, including container lines, exporters and importers. An empirical evidence on the exercise of market power is required to develop competition rules on market dominance at a national and international level. This paper suggests 'port coopetition' as a solution for smaller and regional container terminal operators to survive in a competitive business environment.
