高速铁路与航空运输竞争关系的研究

Research on Competition Relationship between High-Speed Railway and Air Transportation

在阐述国内外学者关于高速铁路与航空运输竞争关系研究成果的基础上,构建客运量对数线性模型,通过测度航空客运量对高速铁路客运量的弹性,确定高速铁路与航空运输是否存在竞争关系,并以京沪高速铁路和京沪航线为例展开研究。结果显示,京沪通道上高速铁路和航空两者没有激烈的竞争关系,且两者运量呈一定程度的正相关性;最后从出行消费需求增长、定价策略、主要客源及高速铁路和航空班次等方面对此结果进行分析。

Based on elaboratingthe researches on competition relationship between high-speed railway and air transportation by scholars, the paper builds the passenger traffic demand log-linear function model, and estimates the degree of competition between them by evaluating the elasticity of air traffic volume to that of high-speed railway and illustrates the method by case study and data of high-speed trains and flights on Beijing-Shanghai corridor. The result shows that there is an fierce competition between traffic volumes of high-speed railway and air transportation and there is positive correlation between them. Finally, the paper analyzes the result further from several other aspects, i.e. traffic demand growth, pricing strategy, main passenger sources and origins and high- speed train and flight frequency, etc.
