随着港口间的竞争日益加剧和港口功能的拓展,港口竞争力所涉及的范围也日益变化,在此背景下,对港口竞争力进行研究就显得尤为重要。为了对港口竞争力进行分析,本文针对港口指标多输入多输出的特点,应用数据包络分析方法,分别引入C2R和C2GS2模型,对中国主要港口竞争力进行评价,以期找出非有效性的港口,并对其提出改进建议。作者根据实际港口输入输出数据指标,对10个港口进行了有效性评价,结果表明DEA用于港口竞争力评价是有效的。 相似文献

ABSTRACTBalancing economic activities with socio-environmental considerations has become a global standard for the construction of large scale infrastructure projects, including ports. In this discourse, stakeholder participation and environmental and social impact assessment (ESIA) have been stressed as important tools that can help port managers to co-create values, avoid conflicts and promote inclusive growth. Drawing on qualitative research tools and stakeholder theory, this paper explores whether and to what extent local stakeholders’ inclusion has substantial influence on addressing their socio-cultural concerns and interest. This is illustrated with a case study of an ongoing port expansion project at Ghana’s largest port of Tema. The findings suggest that although the port authority conducted an ESIA and engaged local stakeholders as part of the planning process, this did not translate into preventing the loss of valuable cultural resources of the local communities. The port authority did not place ‘value’ on cultural resources of the local communities that cannot be expressed in monetary terms. Further, lack of good faith engagement with local stakeholders led to conflicts in some cases that triggered a court action and delays. The paper concludes that stakeholder participation if not applied well, can become a ‘post-political’ tool. 相似文献

ABSTRACTThis paper focuses on the Panama Canal expansion and its impact on American port infrastructure for the attention of academic researchers in maritime transportation and supply chain management (SCM). First, it provides a comprehensive background based on a review of pertinent practitioner as well as academic publications. This is followed by a summarization of the impact of this expansion on the infrastructure of the major East and Gulf Coast (EGC) ports, since these stand to be the most affected. Then it presents a categorization scheme for these EGC ports that capture their likelihood of attracting the expected increase in cargo traffic engendered by the expansion; this is preliminarily supported by the latest data on growth in container traffic. The policy implications of this categorization are then discussed and the paper ends by identifying key SCM research problems exposed by the above. 相似文献

ABSTRACTPort activity plays an important role in facilitating international trade. Sufficient capacity is indispensable for a port to attract flows to a region and retain them. The capacity decision is the result of a trade-off between investment and waiting costs. Traditional methods to value expansion projects do not deal adequately with managerial flexibility in the face of uncertainty from different sources in the complex port environment. In this paper, real options (RO) models are identified as an alternative method to making project valuations and investment decisions, as they attribute the correct value to managerial flexibility under uncertainty. In order to be able to build and use such RO models for port capacity investment decisions, the sources and implications of uncertainty in the port and the different RO model specifications need to be understood. To this end, both the literature about uncertainty in the port context and the literature about real options models are reviewed in order to provide researchers who want to build their own decision-making models, with the necessary knowledge of both fields. The review makes clear that the complex interactions in and competition between the logistics chains and their actors coming together in ports have significant impacts on port capacity. Uncertainty is also caused by uncertain international trade flows and changes in legislation following new technologies and environmental impacts. An analysis of the components of some general RO models shows how the options of flexible output, investment size and timing are valued by RO models in a setting with demand uncertainty. Moreover, the review presents researchers with insights in how to deal with cooperative and competitive interactions in the chain, time to build, cyclical markets and legislation changes. It also shows how to value the expansion and the phased investment options. The new insights resulting from this review are subsequently combined in a framework that serves as a guideline to build RO models for port capacity investments. Finally, an exemplifying application of the framework is used to build an actual port capacity investment decision model. 相似文献

Abstract This paper evaluates the productivity changes in Taiwan's port industry for the period 2003–2007. Based on a ‘three-year-window’ data envelopment analysis method, Luenberger productivity indicators are employed to estimate the productivity changes that account for the success of attempts by port agents to control harbor water quality. This is one of the typical environmental concerns in port operations that prior studies on port productivity changes over time have not considered. The results show that the productivity of Taiwan's port industry has experienced growth over the study period, regardless of whether water quality has been considered or not. At a disaggregated level, however, if a port agent has succeeded in controlling water quality, but we do not consider it, the results will misclassify the agent by understating the port's productivity. 相似文献

This paper investigates the potential of Light Rail Rapid Transit (LRRT) to mitigate the environmental and social burden of ground access systems of an airport. This implies, on the one hand, LRRT's capability in mitigating externalities in terms of noise, air pollution/climate change, traffic incidents/accidents and congestion of airport ground access systems and, on the other, the provision of sufficient capacity to accommodate generally increasing volumes of both air passenger and airport employee demand by connecting the airport to its core catchment area. A methodology for assessing the capability of LRRT operating as an airport ground access system is developed. This methodology consists of models to analyze and predict demand and capacity for an LRRT system and models to quantify the externalities of particular airport ground access systems as well as assessing their prospective savings thanks to the introduction of an LRRT system. The methodology is applied to a large European airport – Amsterdam Schiphol (the Netherlands) – using a ‘what-if?’ scenario approach. 相似文献
