Benefits Assessment of Large Scale High-speed Rail Network in China
Kun Wang,Wenyi Xia,Anming Zhang 인하대학교 정석물류통상연구원 2017 인하대학교 정석물류통상연구원 학술대회 Vol.2017 No.1
This paper examines the impact of China’s large-scale high-speed rail (HSR) expansion, announced in June 2016, on low-cost carriers (LCCs) and the associated benefits assessment of the expansion program. Our analysis suggests that HSR imposes a greater threat to LCCs than to full service carriers, and the HSR expansion that is intended to reach a great number of small cities has left Chinese LCCs with little survival room, even with full airline market liberalization and sufficient airport capacity. By conducting a “propensity score matching” to pair HSR-linked city pairs in China to the counterfactual US airline routes, we find that most of these Chinese routes would be viable markets for LCCs to operate. The benefits of HSR expansion may thus be overestimated if not recognizing the LCCs’ role as an alternative mode to serve these markets. In particular, for the routes to the central and western China with very small travel demand and high HSR construction cost, LCC service could be more cost efficient and operationally flexible than HSR. Our analysis calls for a more careful evaluation of the program and, more generally, a balanced and coordinated HSR and LCC development in China.

For twenty years, in the EU there has been a trend of a lack of maritime infrastructure and a redundance of the road one, which has a negative impact on the economy. The intermodal transport market structure in the EU has not changed over the past ten years. The stability of transport systems due to the lack of changes in the transport market remains under threat, affecting supply chains and networks through the optimization of warehousing and transportation costs. The research methodology is based on a quantitative assessment of cause-and-effect relations between economic growth and transport and logistics in the EU. A statistical analysis of security indicators, intermodal and modal transport, international trade in goods within the EU and in the world trade in goods, the dynamics of GDP of the EU countries, the level of openness of the EU economy, investment and maintenance costs of different modes of transport and infrastructure has been carried out. The results show that in 2000- 2010 there were positive changes in the transport and logistics infrastructure of the EU, which had a positive effect on trade, openness of the economy of the EU, GDP growth. However, at that time, negative effects of environmental impact and the load on road and rail transport were accumulating. Investment in different modes of transport is limited, and technical maintenance and infrastructure maintenance costs form a significant part of GDP of the EU. A slowdown in economic growth leads to budget constraints and infrastructure financing gap. As a result, the freight and passenger intermodal and modal transport market structure remains virtually unchanged. The load on rail and road transport remains stable, despite the reduced level of transport hazards. Transport productivity has declined over the past ten years. Herewith, the intensification of trade and the openness of the EU economies require constant modernization and innovative renewal. The EU policy in this direction remains normative, uncontrolled, which is reflected in investment differences within the EU and maintenance costs.

도로와 철도 운송수단간에 공간적인 경쟁을 고려하고, 트럭 도로운송과 경쟁관계에서 비용상 비교우위에 있는 철도운송의 운송영향권을 찾고자 하였다. 운송영향권 산정모형은 철도복합운송의 간선운송에서 비용경쟁력 있는 운송거리와 철도역에서의 배송거리를 동시에 산정하도록 하였다. 모형에 수단별 비용함수를 적용한 예에서 철도역의 배송영향권은 철도역간 운송거리가 길수록 철도역의 배송영향권이 더 커지는 결과를 나타내었다. While truck and rail transport compete each other over space, the model is proposed to search the transport market area where road-rail intermodal transport offers the more competitive means of transport for interregional movement as well as pickup and delivery around rail terminal. Using the cost function of each modes, the model estimates the result that the greater the length of rail-line, the larger the pick-up and delivery market area of the rail terminal.
