A view of the optimal industrial organisation in the privatisation of railway business

本文从经济学的角度，分析了私有化进程中日本和欧洲主要国家铁路企业最优产业组织的求解。因此，在铁路业务重组中，根据基础设施建设的紧迫性进行组织分离是重要的，组织分离通过增加铁路公司之间的交易成本而产生负面影响，并且根据国家铁路网络规模进行产业组织设计是必要的。

In this study, we analysed the solution of the optimal industrial organisation according to the market environment of each country from the viewpoint of economics for the railway business of Japan and European major powers where privatisation progressed. As a result, in re-organisation of the railway business, it was provided that the organisation separation depending on the urgency of the infrastructure construction is important, that the organisation separation had a negative effect through the increase of the transaction costs between railway companies and that a design of the industrial organisation depending on a national railway network scale was necessary.
