研究建議

一、本研究使用之長期投資類型為「存量」概念之變數，若未來有更詳細之 長期投資資料可以取得，後續學者可以考慮採以變動量之「流量」概念進行實證。

二、長期投資資訊內涵十分複雜，本研究屬於探索性的方式將長期投資類型 分類，若未來資料取得上許可，建議學者可以將長期投資類型再更加細分，以更 精準的方式來進行實證。

三、建議後續學者可以擴大研究樣本，不僅僅探討台灣資訊科技產業上市公 司，進而推出是否長期投資類型存在產業效果。

四、對於公司績效之衡量，本研究只選擇 ROA、Tobin’s Q 做為指標，見意 後續學者可以在納入其它如存貨指標、管銷費用指標、外部環境指標等；或是其 它非財務性指標，如市場占有率、產品品質、顧客滿意度等，使研究結果更加完 備。
