    Abstract: 本文主要研究台灣股票市場效率化趨勢。研究目的有三:首先依據過去對於台灣股票市場是否具備效率化之研究結果,試圖找出台灣股票市場之效率化趨勢。其次藉由股票市場效率化趨勢結果,能對台灣ETF市場的未來發展提供正面的實證依據。最後試圖對政府過去健全股市之政策能促進股市效率化提供解釋。
    本研究資料期間為1991年至2005年,探究股市效率性的論文與期刊為研究對象,利用灰預測模型進行預測台灣股票市場效率趨勢化的實證分析,得到結論如下:
    一、過去15年來台灣股市效率市場比率為逐漸下降,顯示學界對於研究有關台灣股市效率性的文獻中,具備效率性的研究結果部份有逐年下降趨勢。
    二、具備效率性的研究結果部份有逐年下降趨勢,實證結果無法對國內ETF市場未來發展提供有力依據。
    三、對於過去主管機關的施政努力能有助於股市效率化方面,研究結論無法提出有力的解釋。
    雖然研究結果令人有些失望,但投資人想獲得超額利潤,仍需在專業知識上有所提升。對於長期持有的投資人而言,股票指數型基金可以獲得追蹤大盤的穩健報酬,仍不失為一個選擇工具。同時股票指數基金其一籃子股票的組合特性,在操作上可將其視為一避險工具。
