This paper explores the effects of cooperation between rail and air infrastructures in setting per-passenger fees prior to competition among airlines and high-speed rail (HSR) in a transport network. It is shown that, for a sufficiently low degree of substitution, cooperation results in lower fees and greater HSR traffic than under competition. Besides, it leads to more connecting passengers. An empirical application allows for a quantitative assessment of cooperation. Gains to passengers and operators are sizeable when cooperation either involves all infrastructure managers or the rail and the hub airport managers. Welfare gains are in the range of 10.4–11.1%. Our contribution offers an ex-ante analysis about the benefits of intermodal cooperation at the upstream level.

本文探讨了铁路和航空基础设施之间在航空公司和高速铁路 (HSR) 之间在运输网络中进行竞争之前，在设定每位乘客费用方面的合作效果。结果表明，对于足够低的替代程度，与竞争相比，合作会导致更低的费用和更多的高铁流量。此外，它会带来更多的转机乘客。经验应用允许对合作进行定量评估。当合作涉及所有基础设施经理或铁路和枢纽机场经理时，乘客和运营商的收益是可观的。福利收益在 10.4-11.1% 之间。我们的贡献提供了关于上游多式联运合作好处的事前分析。
