| Abstract: | 人壽保險機構為中長期經營之投資者，盈餘或是淨值定義為資產市值減除法定負債之餘額，本研究探討保險人於投資評估期限內，欲達到最適盈餘目標之投資策略，於給定之負債組合及預估現金流量，同時考量保險人之風險接受程度、市場隨時間變化程度與財務收益評估目標，求得每期之最適資產組合及報酬後，檢視公司最適盈餘之分佈狀況。為充分說明模型內容及結果，本文以經營達二十年之某人壽保險公司為例，商品類別包括終身壽險、定期險、定期養老險及終身養老險，依據精算模型預估未來各期之現金流量及準備金，以動態控制理論發展之多期最適投資組合模型運算投資不同年期之債券及股票之資產配置，以檢視最適盈餘數值。經由模擬運算歸納分析結果：（1）資產配置差異的重要因素在於公司對風險趨避程度的不同，因此長期而言，公司盈餘的穩定性也不同；（2）投資期間影響債券年期之配置比例，多期投資模型可定期調整資產配置組合，當投資期間愈長，長年期債券配置比例較高，到期績效較佳，（3）由於壽險商品定價利率於商品銷售已訂定，準備金提存利率愈大於市場利率時，盈餘值為負值之機率愈大。預測壽險公司之清償力，除今年七月份即將實行保險法之風險資本額（RBC）制度，亦可參考本研究之動態財務模型，建立公司內部資產負債管理模型，以提供管理者之財務決策參考及經營決策管理工具。
