A number of transportation infrastructure projects were conducted in Europe during the 1990s with the explicit objective of promoting regional cohesion goals through the improvement of the accessibility of peripheral regions. Given its peripheral situation in the Union, Portugal was a key target for some of these projects. A decade later, it is pertinent to ask whether the new infrastructure achieved its objective of promoting lagging regions. The objective of this paper is to analyze one of the lagging regions in Portugal, to try to establish the link between changes in accessibility levels brought by improvements in the transportation network, and two indicators commonly used in accessibility research (population and purchasing power), while controlling other variables of possible relevance, such as the levels of educational achievement of the population in the region. The analysis is based on the use of spatially autoregressive models which allow the representation of accessibility as spatially lagged variables of first and second order. The results place the contribution of accessibility changes in context, and point at the relevance of education as an alternative policy. 相似文献

The aim of this paper is concerned with the design and development of a functional framework for maritime mode integration in European automotive supply chain management when considering outbound distribution. Furthermore, it provides a readjustment of traditional concepts and terminology with findings that the role of ro-ro port terminals should be considered as decoupling points, poles and postponement platforms. Case studies examine relevant Western European ro-ro port terminals for cars and respective links to assembly/factories of vehicles localized in the hinterland and concludes that ro-ro port terminals reduce logistical friction and impedance, as well as promote space/time compression. 相似文献

This article documents the popularity of five types of trail-based recreation relative to other forms of recreation that tourists frequently participate in on their trips; identifies these trail users’ cross-participation in other outdoor recreation activities; and profiles the travel behaviour, media habits, trip planning behaviour, and demographic and socioeconomic characteristics of day hikers and snowmobilers as two particularly large trail user segments. Findings are based on data from a household telephone survey conducted in Michigan, surrounding states, and Ontario, Canada. Hiking/backpacking was found to be the most popular natural resource-based recreation activity that respondents participated in on pleasure trips taken during the past 12 months; other forms of trail-based recreation were significantly less popular; mountain bikers participated in nature-oriented recreation activities in Michigan at levels that were similar to those of hikers/backpackers; and snowmobiling appeared to be the focus of most pleasure trips on which this activity occurred, in contrast to day hiking, which appeared to be more of an ancillary pursuit. 相似文献

Tourist and recreational use of natural and protected areas in Argentine–Chilean Great Lakes Tourist Corridor has experienced a remarkable growth during last years. Although total amount of use is still within these areas admission capacity, problems arise derived from intensive use in certain places, as well as visitors management concerns in considered critical areas. In this context, a research project was elaborated, approaching the problem of alternative tourism activites management, and focusing on aspects referred to their management and administration in the area of Binational Corridor. This paper refers to one of the dimensions considered in the project: alternative tourism activites demand in the Corridor. Starting from the classification of sustainable tourism niches done by Eagles (1994), a segmentation matrix was prepared and applied. Such analysis has important research, planning and market implications and is critical to the development of suitable services as well as to the design of appropriate management strategies and techniques for those institutions in charge of tourism planning in wilderness areas. Results are not only valid for those activities mentioned in the area of study, but also for other outdoor activities management in the context of North-Patagonian protected areas. 相似文献

Panel data is used to determine the incidence of airport fees on fares in the Spanish leisure market airlines. We also study its structure through an empirical specification of a pricing and demand equation system. The results show the existence of market power, strategic behavior and density economics. We also demonstrate that airlines pass all the airport fees onto customers by increasing fares. Furthermore, we find that the behavior of airlines in routes with the presence of low cost carriers do not differ from other routes. 相似文献
