Preparation of De-listed company Database in the 1950-60ies and Research on features of Disclosure.

该研究项目基于对1949年至1999年期间从股票市场退市的约650家公司的调查。这些公司的历史和发展，特别是在50年代初，是不清楚的。许多这些公司试图在战后继续他们的业务，即使在紧张的经济条件下与混乱，衰退和通货膨胀作斗争。很难更详细地调查这些事件，因为关于这个主题的材料很少。这一次的公司年报已经不存在了，这些公司最初退市的原因是缺乏资金、破产或公司解散。在研究过程中，分析了从1949年5月开始的所有关于这些公司破产、公司解散和合并、资本增加或减少的官方政府报告。我还调查了这些公司的财务报表，但它们并没有澄清这些公司的财务状况。例如，公司的股息率和销售数字并不完全可用。本研究项目的主要目的是建立一个数据库，记录从1949年证券交易所重新开放到1999年的650家退市公司的财务背景。通过记录这些企业的经营活动，可以为今后的发展提供借鉴。根据研究计划，大谷博教授发表了106份企业报告。最后，九州产业大学管理学院的科学期刊上不断发表该项目的成果。到目前为止，已完成约450家公司的报告。

The underlying research project is based on an investigation of about 650 companies delisted from the stock market between 1949 and 1999. The history and development of many of these companies, especially in the early 50ies are unclear. Many of these companies tried to continue their businesses after the war, even under stressful economic conditions fighting chaos, recession and inflation. It is very difficult to investigate these happenings in greater detail, because there very little material on this topic available. Annual company reports of this time are not existing anymore.The initial reasons for these companies to delist were lack of capital, bankruptcy or company dissolution. In the research process all official government reports on bankruptcy, company dissolutions and mergers, capital increase or decrease of these companies starting from Mai 1949 were analysed. I also investigated the financial statements of these companies, but they do not clarify the financial situations of these companies. For example, dividend rate and sales figures of the companies were not entirely available.The main aim of this research project is to create a database of the financial background of 650 de-listed companies starting with the reopening of the stock exchange in 1949 until the year 1999. By documenting the managerial actions of these companies lessons for the future can be learned.Based on the research plan 106 company reports were published by Prof. Hiroshi Oyachi. Finally there are continous publications of the results of this project in the scientific journals of the faculty of Management at Kyushu Sangyo University. So far reports about 450 companies were completed.
