This paper proposes a dynamic weighted model to measure the connectivity of intercity passenger transportation in China. We consider both quality and quantity of the connections of two transport modes, air and rail. Among the 23 major cities selected, Shanghai is revealed to have the highest connectivity level, leading in both air and rail connectivity. Hong Kong, Kunming, and Urumqi are the three cities that predominantly rely on air transportation whose contribution to the connectivity exceeds 80%. This research also suggests that the connections between international cities and China’s domestic network are highly concentrated on a few cities, namely, Hong Kong, Shanghai, Beijing, and Guangzhou, and that Seoul is the best connected international city in terms of its transport links with China. Shanghai-Nanjing has been found to be the best-connected city pair, primarily due to the significant contribution from high-speed rail (HSR) service. Our study shows that the contribution from train service is more than 80% for 19 of the 20 top-ranking domestic routes measured by connectivity. In addition, HSR has become a preferred and dominant option over air on a number of long-distance routes up to 1,300 km. This finding has significant policy implications for transportation infrastructure planning and investment.
This study investigates the effects of high-speed rail (HSR) speed on the airline demand and price. The theoretical analysis suggests that a falling HSR speed increases both airline demand and price. HSR speed effect on airline demand is more likely to diminish with route distance than its effect on airline price. When airline demand is elastic (inelastic) to HSR speed, inter-airlines competition reduces (reinforces) HSR speed effect on airline price. A rare natural experiment of HSR speed reduction in China enables us to estimate the HSR speed effect, alleviating endogeneity problems. The empirical results verify the theoretical predictions: HSR speed reduction increases airline demand and price. The HSR speed effect on airline demand is larger and diminishes faster over route distance. We also produce unbiased estimate on the elasticities of airline demand and price to HSR speed. These estimated elasticities are obtained for the short haul and medium-to-long haul routes respectively. The empirical evidence also suggests that inter-airlines competition reduces HSR speed effect on airline price.
Brief Intro of the Speaker:
Anming Zhang is a Full Professor in Operations and Logistics and holds Vancouver International Airport Authority Chair Professor in Air Transportation at Sauder School of Business, University of British Columbia (UBC). He served as the Head of the Operations and Logistics Division, Sauder School of Business (2003-2005), and as the Director of UBC’s Centre for Transport Studies (2003-2004). He has been the Vice President (Academic & Program) for the World Air Transport Research Society (ATRS) since 2006. Dr. Zhang is the recipient of the “Yokohama Special Prize for Outstanding Young Researcher” awarded at the 7th World Conference on Transportation Research (WCTR) in Sydney, Australia in 1995, and of the “WCTR-Society Prize”, awarded to the overall best paper of the 8th WCTR in Antwerp, Belgium, in 1998. In June 2014, he won the “Best Overall Paper Prize” at the annual ITEA (International Transport Economics Association) Conference on Transportation Economics, Toulouse School of Economics, France.
Dr. Zhang has published about 150 refereed journal papers in the areas of transportation, logistics, industrial organization, and Chinese economy. He has co-authored two recent books: Globalization and Strategic Alliances: The Case of the Airline Industry, 2000, Pergamon Press, Oxford; and Air Cargo in Mainland China and Hong Kong, 2004, Ashgate, London (Chinese editions published both in Hong Kong and Mainland China).
