题目: 空铁合作与机场群:一个收益共享机制的分析

TitleAir-rail Cooperation and Multiple-airports System: A Revenue-sharing Mechanism between Air and Rail Sectors

 

主讲人: 蒋昌敏

Presenter:Changmin JIANG

摘要(Abstract):

这篇文章以一个经济理论模型研究民航与高铁合作打造机场群的一种模式:民航通过报销高铁票鼓励旅客异地乘机,高铁则将来自这些旅客的部分收益与民航进行共享。我们发现当高铁偏向社会福利最大化,或者当机场群中的民航系统是统一管理,这种空铁合作更容易发生。另外,当其中一个机场发生显著拥堵时,空铁合作有助于改善社会福利,因为客流在机场群中能得到更有效的分配。然而,当机场群中的民航系统处于统一管理时,拥堵的内部化可能会导致高铁加入空铁合作的意愿降低。我们还发现在机场群处于竞争状态下,缩短民航和高铁之间的连接时间并不必然改善社会福利。

 

This paper investigates cooperation between air transport and high-speed rail (HSR), with the air sector reimbursing air-HSR transfer passengers for their HSR tickets while the rail sector sharing revenue with the air sector to compensate for the reimbursement. The air-HSR cooperation facilitates forming a multiple-airports system (MAS). The conditions for reaching such an air-HSR cooperation, with either a competing or monopolized air sector in the MAS, are explored. We find that when the HSR operator is oriented to maximize social welfare, or when the air sectors are monopolized in the MAS, the air-HSR cooperation is more likely to arise. Furthermore, airport congestion has important implications on such air-HSR cooperation. Specifically, air-HSR revenue sharing is conducive to welfare improvement as it is more effective in diverting passengers from the capacity-constrained airport. However, when the air sectors are monopolized, their self-internalization of congestion may discourage HSR from engaging in the revenue sharing. We also find that improving connectivity of airport and HSR station may not always be welfare-enhancing with competing air sectors in the MAS. Finally, the Pareto efficient range of revenue sharing to achieve the air-HSR cooperation is identified.

 

主讲人简介(Introduction):

蒋昌敏博士目前任教于加拿大曼尼托巴大学艾斯伯商学院。他的研究领域主要包括多运输模式(如民航与高铁)的竞争和合作关系,运输行业负外部性(如拥堵与污染)的影响与治理等运输经济学问题。在Transportation Research Part B: Methodological,Transportation Research Part A: Policy and Practice, Journal of Transport Economics and Policy, Journal of Business Ethics等国际英文期刊发表论文。

Dr. Changmin Jiang is an assistant professor at the Asper School of Business, University of Manitoba, Canada. His research focuses mainly on the transportation economics, including the competition and cooperation among different transportation model (for example, civil aviation and high-speed rail), and the impact and regulation of transportation externality. He has published research articles on Transportation Research Part B: Methodological, Transportation Research Part A: Policy and Practice, Journal of Transport Economics and Policy, Journal of Business Ethics.
