Roles and Efficiency of Vertical Separation in Railway Industry

首先，我们发现了铁路行业垂直分离和开放准入对运价和效率的理论上的有利影响。其次，我们参与了欧盟、英国和德国铁路行业的案例研究，展示了铁路自由化带来的垂直分离和开放准入带来的经济效率和基础设施管理和准入壁垒等问题。第三，我们对私有化和垂直分离的英国客运列车运营公司(TOC)的生产效率进行了实证研究。此外，我们还比较了从日本国家铁路公司分离出来的民营化TOC与其他日本私营地方TOC的生产效率。

First, we have found theoretically favorable effects of vertical separation and open access of the railway industry on the tariff and efficiency. Second, we were involved in the case studies of the railway industries in EU, United Kingdom and Germany to show the economic efficiency and problems such as infrastructure management and entry barriers induced by the vertical separation and open access due to the railway liberalization. Third, we investigated empirically the production efficiency of privatized and vertically separated British passenger train operating companies (TOCs). Also, we compared production efficiency of privatized TOCs separated from Japan National Railways with other Japanese private local TOCs.
