港口集群的内部竞争

港口集群以产业集群理论为基础,它是研究港口竞争力问题的一种新的理论方法,而集群内部竞争对于提高一个港口的整体竞争力非常有利,它们是加强港口集群竞争力的一个重要因素。本文首先将产业集群的概念应用到港口中来界定港口集群和内部竞争,提出了实施路径来鼓励内部竞争,探讨了如何提高港口集群的效益。

基于博弈论的区域客运通道市场均衡研究

针对区域交通网络与城市交通网络在客运需求结构和市场化程度方面的差异,研究竞争条件下区域客运通道市场均衡状态的预测方法。依据区域交通网络需求特征,构建双层结构博弈模型研究区域客运通道市场内部运行机理。上层是运输方式间完全信息动态博弈,下层为各类出行者广义纳什博弈,模型包括票价、服务频率以及运输工具定员等决策变量对运输方式成本、收益及出行者效用的影响,同时反映出行者决策对运输方式策略的调整作用。算法以最优化理论为基础求解上层博弈的纳什均衡,并将下层博弈等价为一个变分不等式,用对角化算法得到广义纳什均衡,最后通过迭代得到整个模型的近似均衡。以京沪客运通道为例验证模型性能,结果表明:京沪间高速铁路运营将使旅客出行总成本降低,尤其对时间价值较高的旅客;模型较好地模拟运输方式与出行者相互作用的动态过程,为区域交通规划及设计运输产品提供参考。

Are urban bus services natural monopolies?

Although Britain's local bus services have been open to free competition for more than three years, most have continued to be operated as monopolies by the original incumbents. Some competition has occurred, but the incumbents have usually driven off entrants. This paper uses findings from case-studies of competition and from deregulation generally to consider whether monopoly operation has inherent advantages over competitive operation. If so, urban bus routes would be natural monopolies. The evidence suggests that they may be, because single-operator services are more convenient for users.

International emission regulation in sea transport: Economic feasibility and impact

Emissions from shipping due to the burning of the sulphur content of marine fuels conduce to air pollution in the form of sulphur dioxide and particulate matter. Various international organisations and institutions impose environmental standards on their member states to limit the emission of greenhouse gases. This paper examines both the potential effects of the emerging international maritime emission regulations on the competition between seaports and the potential underlying economic motivations fostering the discussion of introducing Emission Control Areas. It focuses on deepsea shipping. Another novelty is that the environmental issues are addressed from a policy, an economic and a legislative viewpoint. For the policy-related part, it is found that the political theory of public choice suggests that not the green lobby but rather the petrochemical lobby is the major driving factor behind the very strict emission caps. A potential port shift from Northern Europe to Mediterranean ports seems unlikely due to logistics disadvantages and service problems in Southern European ports. Finally, no convincing proof was found that the main liner companies would be unprepared for this legislation and should be persuaded to change their routes in favour of Mediterranean ports solely on account of the various emission regulations. The legal analysis, however, showed that the current enforcement regime of MARPOL Annex VI should be improved in order to rule out the possibility of a low degree of compliance and to protect the competiveness of complying ships.
