Outline of Final Research Achievements

Financial statements are said to be a health certificate of a company, and it is believed that the characteristics of a company can be learned from its figures. Therefore, the purpose of this study was to try to identify qualitative attributes of a company from its financial statement figures by using pattern recognition techniques. As a method of pattern recognition, the RT method of the Taguchi method in quality engineering is used. As for the qualitative attributes to be identified, we first attempted to identify the industry. After successfully identifying the industry, we planned to try to identify bond ratings, strategies, and so on.

Academic Significance and Societal Importance of the Research Achievements

1966年から2004年までの財務データを用いて,様々な業種の識別に挑戦した。その結果,商社,百貨店,電力,大手私鉄,造船,カメラの6業種については,各業種の特徴が明確で,概ね識別に成功した。ただし,期間について,1966年頃には明確に識別できているものが,年を追うごとに業種の区別が曖昧になってしまい,識別の精度が低下してしまう。理由としては,企業の体質自体が変化して業種間の違いが縮小していること,会計制度の変更により財務諸表から企業の属性の違いが読み取りにくくなっていることが考えられる。より精度を高めることに挑戦してきたが,決定的な分析手法を確立するには至っていない。
