The role of the maritime industry in the Korean national economy: an input–output analysis

Environmental changes at home and abroad as well as rapid advancement in ocean technology are calling for a great shift in the perception of the maritime industry and for new policy measures. This situation demands that researchers provide policy-makers with accessible and reliable information regarding the role of the maritime industry. This study employs input–output (I–O) analysis to examine the role of the maritime industry in the national economy for the period 1975–1998, with specific application to Korea. This paper, therefore, has two major goals. The first is the development of a static I–O framework for examining the role of the maritime industry in the short run. The second goal is obtaining at least a preliminary indication of the role of the maritime industry. This study pays particular attention to the maritime industry by taking the industry as exogenous and then investigating its economic impacts. Finally, we present the results, which address inter-industry linkage effects in 32 sectors, production-inducing effects, employment-inducing effects, supply-shortage effects of the maritime sector and pervasive effects of price change in the maritime sector.     

The Portuguese maritime spatial plan

Numerous national governments and supranational organizations such as the OSPAR Commission, the European Union and the United Nations Educational, Scientific and Cultural Organization (UNESCO) have underlined the importance of maritime spatial planning (MSP) for balancing and solving conflicts between the needs of different sectors and conservation in the marine space. In the last decade, many maritime spatial plans have been developed around the world. The drivers to develop these plans and the approaches to find solutions for the particular problems differ significantly. The Portuguese national marine jurisdiction is one of the largest in Europe. For the continental part, a maritime spatial plan was initiated in 2009, and entered in 2010 in the final stage of approval. One of the driving forces for this MSP initiative was the claim to extend its continental shelf. The development process was led by a multidisciplinary team. Despite the challenges, the existing as well as potential future marine resources and activities were characterized, mapped and categorized. To overcome conflicts resulting from the many overlapping uses and to assure sustainable development of all sectors, a conflict analysis and evaluation of potential future uses were necessary. The applied zoning scheme represented an exercise of conflict solving and proved to be a powerful tool to promote discussion and participation among stakeholders. The successful implementation of Portuguese MSP will rely largely on its ability to provide efficient management, financial and legal mechanisms to achieve the integration of all strategies and spaces under the Portuguese maritime jurisdiction.     

Strategy,policy, and the formulation of maritime cluster typologies

In recent years, clusters of industry have attracted multilateral attention, from academia and practice, alike. Clusters of industry relate to harbouring regional competitiveness; as such, they have come to be considered as important constructs for strategy and policy, that can be deemed as complementary domains. At the same time, maritime clusters are regarded as dynamic cases from a multitude of viewpoints. The concepts of strategic policy, particularly as they pertain to maritime clusters, require deeper understanding and more thorough analysis. In this context, cluster typologies surface as a useful instrument that can offer valuable insight. While this field instils the eventuality of facilitating policy and strategy within clusters, it remains relatively barren. This instance may present the opportunity to better elaborate on the formulation of models and frameworks that address the intricacies within maritime clusters. The research conducted introduces a three-tier framework for the generation of maritime cluster typologies, that bears the potential to enrich strategic management and its eventual policy implications, towards a more streamlined and informed manifestation.     

National ocean policy—new opportunities for Malaysian ocean development

Being a littoral state, Malaysian maritime sectors provide the basis for the growth and development of marine-related activities. As the country enters the new millennium along with the ‘2020 Vision’ which serves as the basic template against which the economic performance of these sectors should be judged, it poses a new challenge for Malaysia in developing these sectors. This paper attempts to address three basic issues: Firstly, is there any national ocean policy in place? Secondly, are the maritime sectors adequately organized to play an important role in achieving the objectives? Thirdly, what are the opportunities available in developing the ocean?It can be seen that existing policies to develop comprehensive ocean governance have not received the full attention they deserve. Organizational structures governing the ocean for implementing national policies are well in place but in a fragmented and uncoordinated fashion. As a result, sectoral and intersectoral management problems were created such as multiple-use conflicts, overlapping of jurisdiction and duplication of efforts. Environmental problems have also not been properly addressed. A few sectors have been identified as offering opportunities to further develop the Malaysian maritime areas. Among these are marine education and human resources development, marine tourism and the seafood industry.     

An index to assess maritime importance in the European Atlantic economy

Successive marine policies set by the European Union identify the maritime sectors as crucial drivers for growth and jobs in the EU economy. The design of marine policies and the assessment of the importance of the maritime economy need empirical support that provides the basic data to help the decision-making process. This paper proposes a metric, in the form of a synthetic index, to measure and compare the importance of the maritime sectors in the European Atlantic area. The index scores can be used to assess the position of each Atlantic region so that it is possible to compare its performance to the rest of the area. The results show the relative weight of the maritime sectors in the European Atlantic regions and the high heterogeneity among them. Analyzing the maritime economy with this index can provide guidance for the design of economic policies to identify and revitalize the regions with greater potential for Blue Growth in the Atlantic area. This may help to put into perspective the importance of the maritime economy and can serve to improve the socio-economic dimension of the use of marine waters.     

Cooperation and the emergence of maritime clusters in the Atlantic: Analysis and implications of innovation and human capital for blue growth

The so-called ‘blue economy’ is gaining emphasis in European policy making due to the expansion of its relevance beyond traditional economic sectors but also to new and developing ones that exhibit rapid growth. Much of the discourse has focused on the emergence and consolidation of maritime clusters. However, there has been less attention on the regional development aspect and this article provides a timely contribution to filling the gap in knowledge by presenting the findings and analysis of a survey applied to blue economy organisations in Portugal, Spain, Ireland and Scotland. Specifically, issues of innovation, human capital and social capital provide the basis of inquiry around the creation and consolidation of maritime clusters. The article uses the survey data to understand the determinants of the variety of cooperation dynamics. A key finding reveals that participation in innovation activities and absorptive capacity are critical factors in increasing cooperation. From the analysis it is clear that there are significant discrepancies in participation between sectors, such as tourism where participation rates are below average. The article concludes by defining the core activities that should feature in a maritime cluster.     

The geopolitical dimension of maritime security

This article discusses the geopolitical dimension of maritime security, which has been neglected by scholars despite the growing number of studies devoted to a variety of aspects related to maritime security. The first step consists in clarifying the definitions of the two concepts; ‘geopolitics’ and ‘maritime security’. Then the article introduces the geopolitical dimension of maritime security from a conceptual perspective, and then analyses three practical examples of maritime security geo-strategies released in 2014. The results demonstrate that states’ and international institutions’ maritime security objectives and interests are indirectly and directly influenced by geographical and geopolitical considerations, although this link is only tacitly acknowledged in official documents. Scholars and practitioners interested in maritime security are encouraged to further engage with this dimension.     

Measuring the maritime economy: Spain in the European Atlantic Arc

Despite the importance of the socio-economic dimension of the use of marine waters, there has been little research in the field until recently, when interest has grown in the concept of ‘blue growth'. This paper aims to contribute to filling this gap with a socio-economic assessment of the main maritime sectors, focused on the Spanish part of the European Atlantic Arc. To this end, it first proposes a theoretical structure for the maritime economy and then collects and classifies comparable and reliable maritime socio-economic indicators. The data obtained allows us to assess the size of the Spanish maritime sector and the position of the Spanish Maritime Cluster in the wider context of the maritime economy of the European Atlantic, as well as discuss the appropriateness of a strategy of forming clusters at the national level vs. a transnational approach. The results indicate differences between regions in the European Atlantic Arc that complicate the development of integrated policies to stimulate blue growth. Extending our knowledge of the maritime economy of the European Atlantic Arc will make it possible to design strategies that address the real issues, increasing the likelihood of these being effective.

Changing maritime scenarios. The geopolitical dimension of the EU Atlantic Strategy

The European Union׳s Integrated Maritime Policy (EU IMP) is being developed in the framework of a process that is reshaping maritime geographical scenarios and world geopolitics. This process is characterised by a change in States׳ territoriality resulting from their jurisdictional expansion. Over 60% of coastal States in the world possess territory with a more extensive maritime component than the terrestrial component which helps to reaffirm the fragmentation of maritime space and stresses the national vision of the oceans. Unlike the process of ocean space fragmentation that results from its nationalisation the EU Integrated Maritime Policy has a global and cooperative vision, which is particularly evident in the Atlantic Strategy. In this context, this article aims to: (i) provide a first estimate of the size and extent of the territorial changes resulting from jurisdictional claims available to date and their mapping; (ii) consider the case of the European Union as one of special significance with its express policy of maritime spatial projection. The conclusions point to a redefinition of the large territorial pieces of the global geopolitics puzzle and the emergence of a new Atlanticism associated with the EU׳s maritime policy.     

Maritime clusters in diverse regional contexts: The case of Canada

The objectives of this paper are twofold: firstly, the driving forces and the development processes of the different maritime clusters in Canada are described. Secondly, the role of cluster policy in promoting maritime competitiveness in Canada and the key institutional and geographic barriers that affect their growth and development are discussed. The empirical work consists of analyses and assessment of three clusters in different provinces in Canada: Quebec, Newfoundland and Labrador, and British Columbia.     

基于大数据的复杂海运环境下船舶路径自动生成方法

随着全球经济的快速发展,海上运输由于其运力大、运费低而变得更具实用性。然而,这也意味着在海上航道行驶的船只正变得越来越多,这将导致在复杂的海洋环境中航海船只发生事故的可能性会很高。据相关历史的统计,在海域中航行缺乏高精度导航数据会导致大量事故,这种累积的事故信息可以被用来提高航海的安全性。本文通过将蕴含在AIS (Automatic Identification System) 大数据中的经验导航信息挖掘出来,以辅助实现复杂海事环境下安全可靠的船舶路径的生成。本文提出了一种基于大数据自动生成船舶路径的新方法。该方法首先在大量船舶轨迹上通过DBSCAN (Density-Based Spatial Clustering of Applications with Noise) 聚类形成不同的轨迹矢量簇。然后,迭代计算轨迹矢量簇的中心线,并从这些中心线之间的节点-弧段拓扑关系来构建航道网络。最后,基于航道网络来实现船舶路径的生成,对于航道网络未覆盖的海域,则通过海洋环境风险栅格的路径规划来实现船舶路径的生成。不同海域不同AIS数据集进行的多次实验结果表明,本文提出的船舶路径生成方法是有效性。     

The maritime radio spectrum future

Future satisfaction of the electromagnetic spectrum needs of the maritime mobile service is dependent on the translation of those needs to frequency allocations. In September 1979, over 100 countries will consider all of the spectrum, and make changes to meet perceived needs of radio services, including maritime needs up to the year 2000. This conference, the World Administrative Radio Conference 1979, will have a significant impact on future maritime radio operations. Issues, procedures, competing requirements, are explored to enable a better understanding of the regulatory process for frequency allocations.     

A decision-making system to maritime risk assessment

In this study, we propose a fuzzy approach in order to evaluate the maritime risk assessment applied to safety at sea and more particularly, the pollution prevention on the open sea. The work is based on the decision-making system, named MARISA, presented in Balmat et al. (2009). This system allowed defining a risk factor for each ship according to ship’s characteristics and weather conditions. In this novel paper, the proposed system takes into account the ship speed evolution and the ship position with respect to maritime shipping lanes is developed. To validate the method, we present an example of results with real data.     

The development of maritime economics

The arrest of ships in maritime zones beyond internal waters in Belgian maritime law

Opportunities may arise to arrest a ship in maritime zones beyond internal waters, e.g. in the territorial sea and the exclusive economic zone (EEZ). This paper examines the possibilities for arrest in those areas on the basis of jurisdiction ratione loci and ratione materiae. Under Belgian law the territorial sea is not part of the State's territory; accordingly, the Belgian Judicial Code does not provide for an attachment judge nor a bailiff to have jurisdiction in this area and a fortiori in the EEZ. The law of April 22, 1999 solved the problem of territorial jurisdiction in this respect. As far as a ship's arrest in the EEZ is concerned, it is not clear whether the United Nations Law of the Sea Convention (articles 73 and 220) combined with the requirement of a maritime claim, allows for an arrest at all.     

Ocean governance and maritime security in a placeful environment: The case of the European Union

Adopting a critical geopolitics approach that accounts for the mutually reinforcing link between geo-informed narratives and projection practices, this article proposes that ocean governance and maritime security have translated into states' and regional organisations' increasing control over maritime spaces. This leads to a certain territorialisation of the sea, not so much from a sovereignty and jurisdictional perspective but from a functional and normative perspective. The article starts by discussing the ways oceans have been represented and shows that they are far from a placeless void, both in practice and in discourse. The article then frames the analysis of ocean governance and maritime security within critical geopolitics, and elaborates on the case of the European Union's narrative and practice. It concludes on the mutually reinforcing link between discourse and practice in the field of ocean governance and maritime security in general, and on the consequences for the EU in particular. Scholars working on ocean governance and maritime security are encouraged to challenge the traditional view that oceans are placeless.

Digital selective calling and direct printing techniques in the mobile maritime service

For a variety of reasons, communications with ships on the high seas have significantly lagged behind other communications services. For example, the maritime mobile service is practically the only service where manual Morse still constitutes a major part of the communications services. In the last few years, however, some new techniques have been developed which promise to improve maritime communications. This paper provides a background discussion of maritime mobile communications and describes two recent techniques, digital selective calling and direct printing in some detail, together with their impact on maritime communications and safety at sea. Finally, the status of and procedures for international acceptance and standardization are discussed, and national efforts to promote acceptance of these techniques are described.
