项目摘要

Our researches considered two issues: (1) regulatory reform and competition policy regarding vertical integration and vertical separation, and (2) vertical separation of railway industry. On the first issue, we carried out, in particular, the research on (i)a new industrial organization of Japan which is suitable to induce more competition and investment, and (ii) the duty to deal of anti-trust law from the viewpoint of transaction cost economics and relational contracting. On the second issue, we investigated (i) liberalization of Romanian railways under enlargement of EU, (ii) efficiency of Romanian railways, (iii) regulation and efficiency of the UK railways, and (iv) the effect of disused train lines on the regional economy in Japan.We have pointed out that the vertical separation can be effective means to induce more competition and necassary investment of the various network industries, whereas vertical separation has not been employed in the privatization of Japanese network industries, and so the competition work less in Japan than in EU countries. We also scrutinized the vertical separation of railway industry of UK and Romania where vertical separation works. We gave the summary of the history of vertical separation and current problems of railways in UK and Romania, and also did quantitative research of production efficiency after privatization. Finally, we did a case study of the economic effect of disused train lines in Hokkaido, the northern island of Japan.Furthermore, we published two books "Competition: Strategy and Policy" and "Introduction to Microeconomics for Business and Public Policy," based on our research efforts.

我们的研究考虑了两个问题：(1)关于垂直一体化和垂直分离的监管改革和竞争政策，(2)铁路行业的垂直分离。在第一个问题上，我们特别从交易成本经济学和关系契约的角度对(I)适合引入更多竞争和投资的日本新产业组织和(Ii)反垄断法的交易义务进行了研究。在第二个问题上，我们考察了(I)欧盟扩大下罗马尼亚铁路的自由化，(Ii)罗马尼亚铁路的效率，(Iii)英国铁路的管制和效率，以及(Iv)废弃铁路线对日本区域经济的影响。我们指出，垂直分离可以有效地诱导各种网络产业的竞争和必要的投资，而日本网络产业的私有化并没有采用垂直分离，因此日本的竞争作用比欧盟国家要小。我们还仔细研究了英国和罗马尼亚铁路行业的垂直分离，在那里垂直分离是可行的。总结了英国和罗马尼亚铁路垂直分离的历史和目前存在的问题，并对私有化后的生产效率进行了定量研究。最后，我们对日本北部岛屿北海道废弃铁路线的经济效应进行了个案研究，并在此基础上出版了两本书《竞争：战略与政策》和《商业与公共政策微观经济学导论》。
