At the 1952 Census, less than 6 percent of national highways and prefectural roads in Japan were paved, and mechanically-propelled vehicles accounted for only 6 percent of total vehicle registrations; by 1981, 2792 km of expressway were in service (an addi tional 2623 km were under construction or being surveyed) and her industry was dominating world markets for motor vehicles. This paper, drawing on material translated from the Japanese language, examines the history of transport planning and engineering ideas that inspired the modernisation of the highway system in the period after the Pacific War. Three distinct phases are identified: (a) a politically and economically dependent Japanese state which borrowed methods from the U.S.A. in formulating 5-year national road programmes; (b) a more independent state, absorbing western techniques and refining them in 23 urban transportation studies; and (c) a donor state, exporting these ideas to Southeast Asian cities as one instrument of Japanese foreign policy. The triad of international antecedents, domestic context and content, and foreign application is a suitable framework when interpreting the intricate relationships between transport and society. 相似文献

Open registers have developed in recent years as an economic necessity allowing costs to be cut in response to an over-tonnaged marketplace where low to nonexistent profit margins were the norm under the registers of the traditional maritime nations. These open registers allow shipowners the flexibility to reduce their operating costs by, for example, employing cheap foreign crews. The majority of studies in this area have concentrated, quite rightly, on the economic reasons why shipowners flag-out to registers other than their home register. There are, however, a number of more nebulous reasons why shipowners choose one open register as opposed to another. This paper presents the results of a survey which attempts to deduce these qualitative influences over register choice. The specific context of the Isle of Man register is used to illustrate the importance of such factors. 相似文献

Two-sided markets are characterised by the presence of an intermediary and two groups of end-users. In the cruise market, cruise lines may play the role of intermediaries to connect the two end-users, viz. cruise passengers and cruise ports. Our research explored whether the cruise industry can be regarded as a two-sided market, starting with a theoretical modelling. The findings show that cruise lines might be hybrid intermediaries, selling their own ship-based products and services, while offering also a platform to enable the transaction between cruise passengers and cruise ports. This particular business model of a quasi-two-sided market is also reflected in the pricing scheme of cruise industry, whereby cruise ports charge an entry fee from cruise lines and port dues from cruise passengers. We illustrate an empirical analysis on the basis of the cruise market in Japan, and it provides a preliminary clue that the behaviours of cruise ports and cruise lines are consistent with our theoretical framework. The results are not convincingly significant due to data limitations, hence, the concept of a ‘two-sided market’ in the cruise industry call for further empirical research. 相似文献

In a recent paper Wanhill [1] described a method for determining the number of berths that should be provided at a port so that the total usage cost would be minimized. However, in many situations a port will provide a single specialized berth to cater for a particular type of cargo; for example, the unloading of iron-ore at a steelworks or the discharge of oil at a general cargo port. The problem then is not one of deciding on the number of berths to be built but rather that of finding the optimal cargo handling capacity for the single berth available. A model is presented in this paper indicating how such a decision may be made, and two examples give approximate lower and upper bounds for the optimal capacity for many practical cases. A second paper will show how a theoretical model often has to be modified in the light of particular circumstances. 相似文献

Despite ongoing transformations in the maritime transportation industry and the rise of global supply chain systems, most of the world's important container ports remain urban. Ports continue to occupy urban spaces, are embedded in localized knowledge systems, draw on urban labour markets and infrastructure and are subject to local politics and policy concerns. We identify contemporary geographic theories which help us understand the often increasingly urban attachment of core economic activities despite globalization. We explore how these theories may apply to port studies, highlighting both how they have been used by maritime scholars to this point and also why further development and application are warranted. We argue that a central concern of these geographic theories is the articulation of place- and sector-specific processes operating at a variety of spatial scales. This is in contrast to most maritime studies which continue to be dominated by perspectives which emphasize the global logic of the transportation industry and the analysis of space in generalized and abstract terms. We conclude that a re-appreciation in maritime studies of urban economic processes, informed by geographical theory, will provide policy-makers and others with more understanding of why deep connections between ports and urban places still matter. 相似文献
