Price discrimination is practiced by oligopolistic coastal shipping companies in the ‘unregulated’ Greece–Italy routes in the year 2002. Investigation has been carried out ‘per route’—in a doctoral thesis—instead of ‘per market’ which was the so-far erroneous approach of shipping economists. This is so for a host of differentiating factors play a considerable and non-negligible role (like geography, distance, demand, seasonality and others). Service—and price-discrimination—in coastal shipping is affected also by the predetermined ship design which thus is a special feature—but not exclusively—in coastal shipping. Companies in the Adriatic Sea try to extract the greater possible value of the user's willingness to pay, peak and off-peak, group and ungrouped, for social groups (clubs, families and students). Marketing and economics interfere in a complicated—far from the nice world of theory—situation, where maximization of revenue and profit, capacity utilization, intense seasonality and high fixed cost (common and joint costs as well) are a few of the factors that interplay. This paper can be considered as a case study for applied pricing. Excess capacity is also a strategic factor affecting pricing. It is our opinion that the analysis here gives for the first time a complete theoretical and practical account—based on the price lists of the companies—of the pricing policy of the ferry boats running in the Adriatic Sea belonging to coastal shipping companies connecting Italy with Greece and Greece with the European Union (EU). We believe this work to be useful for maritime Europe. 相似文献

The Brazilian ship financing system has some unique features. The funds made available to finance the construction and acquisition of ships are sourced from a tax on import and cabotage freight, payable by the shippers. For Brazilian flagged ships, a portion of the tax generated can be used for the payment of loan instalments. This paper analyses the impact of the tax on the economy as a whole, and discusses the distribution of the tax burden between the shipowner and the shipper, taking into account the maritime transport demand elasticities in Brazil. The paper also analyses the effectiveness of the financing system in reducing the capital cost to shipowner, and the distortion effects produced by the utilization of the tax in loan repayments. The conclusion is that there are important distortions that may threaten the recovery of the maritime industry in Brazil. 相似文献

This paper provides analysis of the medium- and long-distance ferry sectors in Japan. Data has been obtained from semi-structured interviews with ferry operators, port authorities, government officials and from secondary sources. The Japanese ferry industry is assessed on the basis of a range of criteria, including routes and operators, traffic flows, vessels, ports and modal competition. Today, approximately one in every four trucks travelling over distances in excess of 100km in Japan are carried by ferry, and this notwithstanding the alternative of an expanding expressway system. There are clearly lessons here for other countries with long coastlines and congested highways. Many ferry operators in Japan are nevertheless unable to make a profit and clearly there will have to be action taken to secure the future of the industry in the face of high crew costs and competition from low-cost trucking. A potential future opportunity may exist for Japanese ferry lines to extend services to other parts of Asia. Given the success of the European ferry sector as a result of the Single European Market, and pending continued economic cooperation in Asia, potential for any expansion of ferry links between Japan and its near neighbours needs to be evaluated. 相似文献

According to the mid-term review of the EU White Paper on Transport, Short Sea Shipping (SSS) is expected to grow at a rate
of 59% (metric tonnes) between 2000 and 2020. If we consider that the overall expected increase in both freight exchanges
and volume is 50%, sea transport is one of the most feasible alternatives to reduce traffic congestion on European roads.
Maritime transportation may compete with road transport as far as certain traffics are concerned, but only when assuming external
costs. This paper analyzes several intermodal transport chains involving a sea leg by comparing the effect of pollutant emissions
from different ship types and road transport in terms of potential external cost savings. The translation of these emissions
into environmental costs shows, for certain conditions, savings in the case of sea transport that would justify the use of
an environmental bonus to promote the sea option. 相似文献

文章首先介绍了目前发达国家所采取的沿海溢油监测监视防范体系,分析了雷达数据在其监测监视体系中的地位和作用,然后介绍了我国在沿海溢油监测监视防范体系建设方面的现状,并分析了制约雷达数据在我国实际应用中存在的问题。利用Envisat的ASAR数据对发生在西班牙海域的溢油事件进行了半自动化的溢油油膜范围的提取,给出了处理结果,并对目前国外就雷达数据在其监视监测体系中的应用方法进行了介绍。根据国内外沿海溢油监测监视体系的现状对比和国内制约因素的分析,结合实例数据的分析处理结果,表明雷达数据在沿海溢油监测中具有突出优点,未来在我国近岸海域溢油监测体系中将得到较为广泛的应用。 相似文献

This article is concerned with an analytical summary of how the Japanese container ports have been taking place overcapacity problem in a systematic way. It focuses on institutional aspects of the overcapacity problem from the viewpoint of accounting cost and opportunity cost. The first issue arises due to the port authority's accounting system and insufficient disclosures of financial statements of port business to the port users and taxpayers. The second issue is inherently related to resource allocation between the state government and local governments through the budget system and income distribution programmes. Since a proper allocation of economic resources in the port sector as a whole will depend on investment decisions being taken within a coherent framework for ensuring that costs are passed on to port users, these issues are closely related to each other in reality. Although the budget system is completely controlled by the state government, the local governments have authoritative power over port planning, financing, and management, which is assured by the Ports and Harbours Law. The overcapacity problem appears to be an inevitable result. 相似文献

以上海第(6)层粉质黏土为例,研究了固结压力、各向异性及结构性对滨海地区粉质黏土渗透特性的影响,并通过电镜扫描(SEM)进行粉质黏土微观渗透机理的分析。研究表明,粉质黏土渗透系数随着固结压力增大而减小,粉质黏土水平方向的渗透性大于垂直方向;重塑土因受扰动渗透性反而变小。微观分析显示,固结压力增大使得土颗粒间的孔隙变小;垂直方向存在较多粒状聚体,而水平方向则以片状或板状聚体为主;重塑土受扰动后小颗粒填充了大孔隙。粉质黏土颗粒间的孔隙类型、接触方式等微观结构变化,是其宏观渗透性差异的根本原因。 相似文献

Abstract This article argues that using the public sector and the private market in the historically delineated and traditional ways offers only the bluntest of tools with which to approach the complex problem of coastal zone management. It therefore seeks to provide a basis for reformulating our understanding of sectoral responsibility with regard to resources management. First, it conceptually analyzes the relative strengths and weaknesses of the two sectors. Second, it examines three examples of coastal resources management—beaches and shorelands, artificial reefs, and coastal wetlands—in analyzing the complexities of the coastal management challenge and the limitations of our current approaches. Finally, we provide an alternative perspective on how these common property resource allocation decisions can be made. 相似文献
