證券投資信託基金已是國人重要的理財主要工具之一。回顧我國證券投資信託基金發展的歷史，從早期為吸引外資投資我國而開放設立證券投資信託基金，接著也成為我國投資人重要之投資工具，到後來開放境外基金得以在國內顧問，境外商品就此開始深受國人喜愛；直至證券投資信託及顧問法通過，主管機關依授權訂定境外基金管理辦法後，國人得投資經由總代理人依法向主管機關申請核准或申報生效在我國境內募集銷售之境外基金，也開啟了境外基金與證券投資信託基金於國內銷售既競爭又合作之關係。 境外基金與證券投資信託基金於國內銷售之競爭合作的關係，不僅在產品創新及銷售金額等方面，本文所關切的是，在境外基金管理辦法公佈實施後，我國證券投資信託基金相關法規發生了什麼變化？有無任何規定是因為境外基金管理辦法實施後，證券投資信託基金相關法規不得不隨之調整者？還有，有無任何境外基金的規範進而影響我國既有之規定？當然，是否也有境外基金業者因為境外基金管理辦法的實施，必須調整其基金的運作與內控制度，以符合我國之法令規定？甚至，有無任何境外基金註冊地，為配合我國市場及法制環境，而更改其法令者？ 本文之研究係以比較我國證券投資信託基金相關規範，與境外基金管理辦法暨我國境外基金主要註冊地之法源，尋找彼此規範不同處，了解其為何規範不同的理由與背景，探討規範不同點之存在理由合理否，進而探詢彼此間之衡平性，以作為提供我國基金產業法律發展之參考資料。 最後結論除回覆前述問題並舉例說明外，並嘗試歸納本文之研究結果，對證券投資信託基金與境外基金之法制規範差異性比較，採見解扼要衡平重申外，並期對我國基金產業之整體發展提供建言。 / The securities investment trust fund is one of the important financial investment vehicles in Taiwan.
