为总结我国水运基础设施建设经验并提出发展建议,从码头通过能力、大型化专业化码头体系、智能发展、支持保障等方面总结沿海港口基础设施建设取得的成就,从航道建设、码头体系、航道绿色化数字化等方面回顾内河港口基础设施建设成就,指出沿海港口基础设施建设中存在港口集疏运体系建设有待完善、部分货类码头通过能力需要调整、部分港口基础设施与城市发展存在冲突,内河航道建设中存在内河高等级航道比重偏低、部分通航设施碍航、内河水运基础设施建设与其他部门协同发展仍然存在一定障碍等不足,以及内河港口基础建设方面存在规模化、集约化、现代化水平普遍较低的问题,从优化沿海港口设施供给、加快内河高等级航道建设、加强并完善港口集疏运体系等方面提出发展建议。 相似文献

This chapter presents a summary of the findings of the workshop on ‘Analytical and Institutional Methods and Frameworks’. The paper discusses the nature of the analytical methods used in the papers presented and the purposes for which they were employed, which were generally to either assist in the planning and operation of public transport or to monitor the efficiency and effectiveness of transport services. Subsequent sections examine issues related to data collection and management, and the more general issue of institutional arrangements. Policy and research agendas needed to support further consideration of the subject are then identified. 相似文献

This paper explores the current state of coastal and inland shipping in Tanzania. It provides an overview of the state of ports and shipping in Tanzania, and the reasons underlying the present crisis of competitiveness in terms of both global pressures and national and regional dynamics. Problems of competitiveness are at least partially due to under-investment, management failures, skills shortfalls and difficulties in interfacing with the railway network. Less easy to resolve structural problems include the great imbalance between imports and exports, heightened regional competition and ongoing political instability in the Great Lakes region. 相似文献

As the controversy over Outer Continental Shelf (OCS) oil and gas leasing continues, with environmentalists and fishermen seeking to block or delay leasing decisions that they think will adversely affect their interests, the need for better estimates of the environmental costs associated with OCS development becomes increasingly apparent. Although high degrees of precision in such estimates may never be economic, let alone feasible, better knowledge would reduce the uncertainty surrounding the magnitude of such costs, and would make it easier to come to grips with the problem and reduce, if not resolve, the controversy. 相似文献
