摘要


根據財團法人保險事業發展中心之統計,截至2007年12月,我國整體壽險市場之初年度保費收入已超越傳統型保險,顯示投資型保險將取代傳統型壽險成為市場主流。過去國內對於投資型保險商品的研究多針對的費用及績效作探討,鮮少有針對投資型保險商品的風險進行衡量,因此,本研究希望能藉由投資型保險商品的實證結果使投資人了解投資型保險商品潛在的投資風險,以作為參考。 本研究針對投資型保險商品的風險值作探討,將投資組合依投資人風險偏好分為三類型,使用傳統風險值評估模型及屬極端值理論的超越門檻值法評估投資型保險商品的風險值水準,並利用回溯測試法找出適合衡量其風險的估計模型,作為風險值的估計結果。 在高信賴水準下,極端值理論在回溯測試中都有極佳的表現,但在低信賴水準下,則由傳統模型勝出。在考量時間成本與效率下,低信賴水準下採用傳統模型即可,而高信賴水準下,極端值理論則優於傳統模型。 績效評估方面,將風險值導入傳統指標的績效評估後,在積極型投資組合的排名有較大幅度的變動,而保守型及穩健型投資組合排名的變化並不大。

According to the statistics of the Taiwan Insurance Institute, up to December 2007, investment-oriented insurance products have replaced the traditional life insurance to be the most popular life insurance products. In the past years domestic research about investment-oriented insurance products laid great stress on insurance and performance evaluation, but paid less attention to measuring the position risk about investing in investment-oriented insurance products. Thus, this paper aims to help investors understand the latent risk of investment-oriented insurance products for the reference of choosing position or hedging. This paper employs traditional VaR (VaR at Risk) models and POT (Peak over Threshold) model belonging to EVT (Extreme Value Theory) to evaluate the risk level of investment-oriented insurance products, and then to choose relatively appropriate model by demonstration models as the conclusion of estimation about VaR. Under high confidence level, for back testing, EVT models have better performance. But under low confidence level, traditional models perform better than EVT models. Thus, under low confidence considering time cost and efficiency, we suggest employing traditional models as the estimation models. However, EVT models obviously surpass traditional methods under high confidence level. The empirical results shows that after introducing the VaR into the performance evaluation indexes, the ranking of the active portfolios have changed compared to those by traditional ones, but the ranking of the moderate and conservation portfolios have not.
