會計資訊有用性之研究

Abstract

由於近年社會大眾對於會計資訊是否可供決策判斷多所指責，多認為會計資訊無用，無法判別財務危機公司。本研究希望藉由分析財務危機公司之財務報表，由其中得知問題資訊，來證明會計資訊的有用性。 本研究分析西元1995年至2005年間發生財務危機之48家公司，藉由財務比率分析及財務報表附註揭露分析檢測危機前之財務報表是否存在可供決策之資訊。 研究結果顯示樣本中之財務危機公司於發生危機前之財務報表皆有資訊揭露於其中，足證財務報表實可供判斷公司良窳。本研究尚提出一閱讀財務報表附註之方式，期可協助投資人於繁厚之附註中按圖索驥，使用自如。

Recently, investors doubt the usefulness of accounting information. They think that it is impossible to make investment decision just by a company's annual report. This study wants to prove the accounting information content is able to assist investors. This study analyzes 48 financial crisis companies range from 1995 to 2005. We analyze not only these companies' financial rate in traditional ways but also their reports' notes. The result shows that there actually was information inside accounting reports before company's financial crisis. According to our result, we can tell bad companies from portfolio. Additionally, our study addresses a set of measures to analyze accounting reports' notes. Hoping we can educate people how to use accounting reports.
