Competition of spatial service hinterlands between high-speed rail and air transport in China: Present and future trends

Abstract

Abstract:The rapid development of high-speed rail (HSR) and air transport in China has encouraged research on the spatial effects and safety of these two modes of transport, and on the competition between them. We report here an investigation of the effects of competition between HSR and air transport in China from a geographical perspective. The spatial service hinterlands for HSR and air transport accessible within one and two hours by road transport were investigated using a method based on a geographical information system and the overlapping service hinterlands of HSR and air transport were established. A city with both HSR stations and airports, or that was accessible to HSR stations and airports within a certain travel time by road transport, was defined as the overlapping market. The spatial effects of competition between HSR and air transport at present and in the future were then studied with respect to the planned HSR network and airports. The results showed that both HSR and air transport tend to serve areas with high population densities and well-developed economies and in 2012 most of the population and GDP in China were accessible within two hours by road transport to an HSR station or airport. The different technical and economic characteristics of HSR and air transport determine the advantage markets. Spatially, the service hinterland of HSR mainly focuses on urban agglomerations and economic corridors in the eastern and central regions, whereas air transport has a competitive advantage in the more inaccessible western region of China. The overlapping market of HSR and air transport will become increasingly large in the future and cities with a population of over one million and cities within 30 km to both airports and HSR stations will become the major competitive markets. Considering the cost of construction and the number of passengers required for economic operation, as well as the competition with air transport, it is suggested that the construction of some HSR projects in the western region of China should be canceled or slowed down.

Seasonality of flights in China: Spatial heterogeneity and its determinants

“…Thus, we applied the proportion of domestic tourism revenue and regional GDP (TOURISM) to represent the region's dependence on the tourism industry. HSR development brought competition in spatial service hinterlands between HSR and air transport (Wang et al, 2015). Newly launched HSR stations or changed HSR links might induce flight seasonality.…”

Borrowing Power from Potential Entrants and High-Speed Rail: Entry Pattern of China’s Low-Cost Carrier

“…In doing so, we assess both the substitutability and complementarity effects that coexist in Spring's entry decisions, particularly when route distances are split based on the characteristics of Spring's business model. We also consider the presence of HSR at the endpoint(s) of a route, which is critical since the number of airports overlapping with HSR services has increased year by year [41,42].…”

A Two-Dimensional Clustering Method for High-Speed Railway Trains in China Based on Train Characteristics and Operational Performance

“…Dobruszkes [13] pointed out that if HSTs (high-speed trains) are to compete successfully with airplane, a number of factors come into play, including travel time, frequencies, fares, airline hubs, geographical structures of urban regions, etc. Wang et al [14] showed that the operational performance of HSR trains is not only influenced by population densities and well-developed economies, but also by fares, frequency, travel distance, departure time and distance from airports/HSR station to the city centre.…”
