我们提供了一个理论框架来讨论铁路行业的市场规模和垂直结构之间的关系。该框架基于一个简单的下游垄断模型，有两个投入供应商：劳动力和铁路基础设施公司。下游公司（即火车运营公司）的运营给铁路基础设施公司带来了成本。我们发现，市场规模较大的下游企业更有可能与铁路基础设施企业整合。这与铁路行业的现象是一致的。
We provide a theoretical framework to discuss the relation between market size and vertical structure in the railway industry. The framework is based on a simple downstream monopoly model with two input suppliers: the labour force and the rail infrastructure firm. The operation of the downstream firm (i.e. the train operating firm) imposes costs on the rail infrastructure firm. We show that the downstream firm with a larger market size is more likely to integrate with the rail infrastructure firm. This is consistent with the phenomenon in the railway industry.
