成長機會對會計資訊評價攸關性之研究 摘要 公司市場價值是由現有資產價值與未來成長機會價值所構成,其中成長機會價值占公司價值的比重往往很大;然而只有擁有未來成長機會的公司才能不斷提高其價值,資訊使用者若僅以目前盈餘數字來評估公司價值,而忽略了影響深遠的未來成長機會,便會遺漏重要的財務資訊而導致不正確的投資決策。因此本文引用Ohlson(1995)及Feltham and Ohlson(1995)模式研究會計資訊之攸關性。本文旨在探討會計評價過程,除了探討成長機會對於會計資訊評價之攸關性(假說一)及其對盈餘持續度之影響(假說二)及成長機會對帳面價值評價攸關性之影響外(假說三),還探討成長機會對會計保守性的影響(假說四)。本研究嘗試以資產帳面值/資產市值(A/V)作為成長機會之替代變數將所有公司分四組以進行實證分析;另外本文為了消除混淆效果在敏感度分析中加入規模因素、虛擬變數,並且使用其他成長機會替代變數作更進一步分析。本研究結果有以下結論:(1)成長機會愈大之公司會計資訊對股價之解釋能力愈小(2)成長機會愈大之公司其異常盈餘之係數愈大(3)成長機會愈大之公司增額資訊內涵愈小(4)成長機會愈大之公司保守係數愈大
