항만에 대한 많은 연구가 학계에 발표되어 왔고, 이러한 항만에 관한 연구들은 항만발전에 크게 기여하였다. 그러나 지금까지 학자들의 다양한 연구결과들을 종합적이고 체계적으로 분류하고 이를 정리한 연구가 없다는 것이다. 따라서 본 연구는 이를 정리하고 체계화하기 위해 최근까지 수행된 국내 항만경제학 관련 연구에 대한 성과들을 전체적인 조망하는데 연구의 목적이 있다. 이를 위해 국내 대표적인 항만경제학 관련 연구지인 한국항만경제학회지에 1991년부터 2010년까지 659편의 게재논문을 대상으로 메타분석을 실시하였다. 항만경제학과 관련된 연구주제와 방법에 대한 메타분석을 시행하기 위해서 다음과 같이 총 3개의 연구문제들을 설정하였다. 먼저 연구자의 특성에 대한 분석을 수행하고, 연구주제에 대해서 논의하며, 연구논문에 사용된 주된 연구방법에 대한 분석을 통해서 전반적인 연구내용을 파악하였다. 분석결과 항만경제학은 양적으로 많은 성장을 이루었으며, 최근 들어 항만에 대한 관심의 증가와 연구자의 증가 등으로 질적인 측면에서도 이전 보다 연구주제와 연구방법이 세분화되고 다양화 되면서 더욱 발전해 나가고 있다. 특정 연구방법이 지나치게 편중되는 경향을 보이고 있는 것에 대해서 다양한 연구방법을 권장하는 내용의 논문투고요령의 보완도 필요하다. 그리고 본 연구의 성과에 기초하여 유관 학회 연구와의 비교를 통한 연구도 보완되어야 할 것으로 보인다.

This paper presents a user-oriented port expansion simulation model that determines the future economic port capacity to meet the projected demand. The model consists of two parts; a physical impact simulation, and an economic impact simulation. The first part of the model simulates the effects caused by the port capacity expansion. The second part evaluates the port economics due to changes in the port capacity. The model was validated by applying it to the actual port expansion followed at the Port of Mobile, Alabama. A case study is then presented to demonstrate the capacity of the model with a coal handling port, the McDuffie Terminals at the Port of Mobile.

It is extremely important to predict the logistics requirements in a scientific and rational way. However, in recent years, the improvement effect on the prediction method is not very significant and the traditional statistical prediction method has the defects of low precision and poor interpretation of the prediction model, which cannot only guarantee the generalization ability of the prediction model theoretically, but also cannot explain the models effectively. Therefore, in combination with the theories of the spatial economics, industrial economics, and neo-classical economics, taking city of Erdos as the research object, the study identifies the leading industry that can produce a large number of cargoes, and further predicts the static logistics generation of the Erdos and hinterlands. By integrating various factors that can affect the regional logistics requirements, this study established a logistics requirements potential model from the aspect of spatial economic principles, and expanded the way of logistics requirements prediction from the single statistical principles to an new area of special and regional economics.

Decision Science or Decision Analysis can be described as a scientific methodolog to provide suitable quantitative information for the decision maker to be able to selected the best feasible alternative on the given decision environment and thus we can say that where there are decision problems, there needs the decision analysis to be applied to them. International shipping is generally said to be the cheapest and most widely used means of transport in international trade and each of the hundreds of seaport. So far as the decision makings in the shipping and port transportation are concerned, of real importance is to understand what the decision problems in each of shipping and port transportation really are and to recognize the meaning of relevance between shipping and seaport in the outworn phrase, that is to say, "The chain is as strong as its weakest link." This paper is intended to present a literature survey on the applied decision analysis to shipping and port transportation problems which have actually been involved in the wide variety of decision environment. At first, the author suggests four divisional framework such as decision analysis in each field of Shipping Economics, Management and Operations of Shipping, Port Economics, and Port Operation and Management, according to the main concern of the decision environment, and then the literature surveys on those four major divisions are described including the problems and solution approaches in each case. The author concludes the paper with the comment on the need of joint research around this area by citing the phrase of "a process of updating the decision makers' intuitions."s' intuitions."quot;

Purpose - The purpose of this study is to propose strategies of improving efficiency of 20 listed port companies in China based on analysis of their input-output indexes from 2014 to 2018. Research design, data, and methodology - In this paper, the relevant input-output indicators of 20 listed port companies in China from 2014 to 2018 were adopted. Data derived from the company annual reports announced by Shanghai stock exchange and Shenzhen stock exchange. Comprehensive efficiency and pure technical efficiency were measured from output perspective by DEA and Malmquist index, and efficiency changes and regional efficiency were analyzed. Result - The results showed that the efficiency value of 20 listed port companies in China fluctuated and increased during 2014-2018, regional efficiency was unbalanced, and change of MPI was influenced by internal factors and external factors. Listed port companies affected by internal and external factors needed to make appropriate response to internal and external factors. Conclusion - The research conclusion can provide important reference information about management and planning for port companies in China and related areas. However, this paper is limited to the availability of data. So the improvement scheme for listed companies in inefficient regional ports needs further study, such as using AHP method.

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.

국제해사기구(IMO)의 환경규제 강화에 따라 친환경 선박의 수요가 증가하고 있으며, 특히 LNG 추진선박이 조명받고 있다. 이에 따라 항만의 경쟁력 확보 및 LNG 추진선박의 활성화를 위해 LNG 벙커링 인프라 구축이 필요한 시점이다. 그러나 현재 관련 인프라를 구축한 국내 항만은 전무한 실정이며, 선행연구는 LNG 벙커링 산업 차원에서의 경제적 효과만을 중심으로 진행되었다. 이에 본 연구에서는 2015년 지역연관산업표를 활용하여 부산항에 LNG 벙커링 인프라를 구축할 경우 지역 내 경제적 파급효과에 대해 살펴보았다. 2023년 기준 부산항에 LNG 벙커링 인프라를 구축할 경우, 예상 사업비는 2조 1,091억 원이었다. 부문별 평균 생산유발계수는 1.223, 평균 부가가치유발계수는 0.372, 평균 취업유발계수는 7.58로 분석되었다.

In order to effectively relieve the traffic pressure of the city, ensure the smooth flow of freight and promote the development of the logistics industry, the selection of appropriate port logistics location is the basis of giving full play to the port logistics function. In order to better realize the selection of port logistics, this paper adopts the entropy weight method to set up a multi-dimensional evaluation index, and constructs the evaluation model of port logistics location. Then through the actual case, from the environmental dimension and economic competition dimension to make choices and analysis. The results show that port d has the largest logistics competitiveness and the highest relative proximity among the three indicators of hinterland city economic activity, hinterland economic structure, and port operation capacity of different port logistics locations, which has absolute advantages. It is hoped that the research results can provide a reference for the multi-dimensional selection of port logistics site selections.

As national economies globalize, demand for intercontinental container shipping services is growing rapidly, providing a potential economic boon for the countries and communities that provide port services. On the promise of profits, many governments are investing heavily in port infrastructure, leading to a possible glut in port capacity, driving down prices for port services and eliminating profits as ports compete for business. Further, existing ports are making strategic investments to protect their market share, increasing the chance new ports will be overcapitalized and unprofitable. Governments and port researchers need a tool for understanding how local competition in their region will affect demand for port services at their location, and thus better assess the profitability of a prospective port. We propose to develop such a tool by extending our existing simulation model of global container traffic to incorporate demand-side shipper preferences and supply-side strategic responses by incumbent ports to changes in the global port network, including building new ports, scaling up existing ports, and unexpected port closures. We will estimate shipper preferences over routes, port attributes and port services based on US and international shipping data, and redesign the simulation model to maximize the shipper's revealed preference functions rather than simply minimize costs. As demand shifts, competing ports will adjust their pricing (short term) and infrastructure (long term) to remain competitive or defend market share, a reaction we will capture with a game theoretic model of local monopoly that will predict changes in port characteristics. The model's hypotheses will be tested in a controlled laboratory experiment tailored to local port competition in Asia, which will also serve to demonstrate the subtle game theoretic concepts of imperfect competition to a policy and industry audience. We will apply the simulation model to analyze changes in global container traffic in three scenarios: addition of a new large port in the US, extended closure of an existing large port in the US, and cooperative and competitive port infrastructure development among Korean partner countries in Asia.
