摘要
以港口为核心的多式联运系统之间存在激烈竞争,为了解决干支线运输系统高效运营和协调的问题,在考虑托运人、支线承运人、港口、干线承运人竞争与合作关系的基础上,构建了港口补贴模型,提出了一种实现系统协调的港口补贴激励策略.研究表明,干线港的补贴策略影响市场运价均衡、支线承运人间竞争,以及干支线运输系统整体效益.选取干线承运人作为补贴对象,有利于港口的市场份额和运输系统的总收益,而对托运人提供补贴,则能更有效地降低市场运价.因此,在考虑系统内各环节运营成本的基础上,港口可以制定最优补贴策略以实现阶段性发展目标.
There is fierce competition among port-oriented main-feeder transport systems.In order to improve the connecting efficiency and coordination between main lines and feeder lines,a model of port subsidy is developed,considering the competition and cooperation among multiple participants in the multimodal trans-port system,such as shippers,feeder carriers,port authorities,and main line carriers.Moreover,the optimal subsidy policies are provided and compared.Results indicate that subsidy policies have significant impacts on the competition relationship and market equilibrium state.Subsidizing main line carriers improves the market share of ports and net revenue of the whole transport system.Meanwhile,subsidy to shippers can reduce the e-quilibrium freight rate.Therefore,port authorities should design a customized strategy for phased development goals based on the various operational costs of the participants in the multimodal transport system.
