    Abstract: 傳統精算的資產負債管理大多採用確定投資模型(Deterministic Investment Model),即以過去的經驗設立「精算假設」,但是這樣的假設常常無法精確的呈現未來的趨勢。近幾年來,財務經濟的概念已更趨普遍的應用在保險或退休金的資產負債評估上,本研究的目的是將隨機投資模型(Stochastic Investment Model)應用在保險或退休金長期負債的評估並對其提出有效的投資避險策略的建議。所以本研究的第一部份,便是根據過去的台灣總體經濟資料,在精簡參數的考量下,建構一個以因果關係(Causality)為基礎的一個以可呈現台灣市場未來趨勢之隨機投資模型。根據此投資模型,我們針對不同的退休金負債形式,以靜態避險(Static Hedging)的方式去求得各資產的最適投資配適比例。本研究所採取的避險策略是針對一般退休基金所常用的資產,尋求最適之投資組合,而非為了達到完美的避險而尋求更複雜的投資資產的選取。從模擬的結果中發現,隨著負債到期日的增長,投資在風險性高報酬率佳的投資標的物上的比例也越來越高。另外,整體而言,我們由模擬中可得出,使用多重資產的投資組合方式優於單一資產所達到的避險效果。
