    Abstract: 本研究探討CAPM模型及條件CAPM模型對於台灣股市的解釋力,並透過選擇不同的無風險利率,觀察模型解釋力是否會受到無風險利率的選擇而改變。由於台灣市場上三個月期國庫券發行頻率及數量皆不熱絡,因此在台灣的文獻中,大多以短期的定期存款利率作為替代。然而,定期存款利率具有僵固性的問題,因此無風險利率的選擇便形成了一個課題。
    本研究主要研究對象為台灣上市公司,剔除金融及保險等高槓桿產業,選取2005年1月至2017年12月的期間,並去除受金融海嘯影響較大之期間(即2009年),在台灣經濟新報(TEJ)中,所有使用到的研究變數皆具有完整月資料的台灣上市公司,一共602檔股票。
    透過Sharpe-Lintner CAPM方程式所估計出各股票的Beta值,由小至大均分為15個投資組合。本研究假設股票的Beta值會隨時間而改變,因此在投資組合形成後,將重新估計投資組合的Beta值。最後將估計出的投資組合Beta值與實際的投資組合超額報酬率,進行CAPM模型及條件CAPM模型的迴歸實證。為了驗證無風險利率的選擇是否會對模型顯著性造成影響,我們選擇使用第一銀行三個月期定存利率及二年期政府公債殖利率,分別放入迴歸實證中,並針對結論進行比較。
    實證分析的結果顯示,無風險利率的選擇並不會改變模型迴歸實證的結論,僅會改變在同一段時間內,牛市及熊市之間的月份數差。而在2010年至2017年間,CAPM模型對於台灣股市不具有解釋力,亦即投資組合的Beta值與市場超額報酬率並不具有顯著為正的線性關係。在將市場區分為牛市及熊市的條件下,投資組合的Beta值與市場超額報酬率呈統計顯著的關係,且牛市時之市場超額報酬率顯著為正,熊市時之市場超額報酬率顯著為負。
