基于旅客时间价值的高铁民航空间距离研究

近年来，我国高速铁路快速发展，对民航市场产生冲击。本文利用时间价值的相关理论模型对高铁与民航的竞争空间距离进行分析。通过建立旅客出行时间价值与民航相对于高铁的边际时间节省成本之间存在的关系来探究民航与高铁的竞争性问题，并建立了边际时间节省成本的计算模型，通过模拟的方式，观察了在不同的假设条件下，民航与高铁在不同的出行距离下所对应的消费者群体。总体上，随着旅客时间价值的变化，高铁民航的有效竞争空间距离以800km为界，且随时枢纽衔接时间、运行速度等变化而变化。

Research on the Spatial Competition Distance between Civil Aviation and High-speed Railway from the View of Time Value of Passengers

In recent years, the civil aviation market has been impacted by the rapid development of China''s high-speed railway. The competitive spatial distance between high-speed rail and civil aviation is explored through the application of the theoretical model related to the value of time. The competitiveness of civil aviation and high-speed rail is analyzed by establishing the relationship between the value of passenger travel time and the marginal time saving cost of civil aviation relative to high-speed rail, and the calculation model of marginal time saving cost is established, and the consumer groups corresponding to civil aviation and high-speed rail at different travel distances under different assumptions are observed by means of simulation. In general, with the change of passenger time value, the effective competitive space distance of HSR civil aviation is bounded by 800km, and its change is affected by the connection time of hub and operation speed, etc.
