Abstract:	隨著利率降低，承保利潤下降，壽險公司在投資端的壓力越發嚴重，保險公司在資金運用和風險控管的要求越來越高。經濟資本(economic capital,EC)是保險公司其中的一種風險度量方式，能夠根據公司自身特性使用各種數據和模型評估自己的風險。本文以中國大陸的壽險公司為例，選取了國債和政府機構債券、企業債、證券投資基金和股票作為投資風險中的研究對象，採用各類GARCH(1,1)模型搭配殘差為skew student和normal之分配和動態與靜態之t-Copula和n-Copula模型計算在不同的信賴水準下壽險公司在市場風險的經濟資本，並進行風險值VaR的回測，對比不同Copula模型的差異性，供壽險公司在進行風險度量時的參考，實證結果表示動態的t-Copula對經濟資本的預測效果最好。 The pressure for investment business of life insurance companies is more and more severe due to the declining interest rates and underwriting profit. The economic capital is a risk measurement method which allow companies use their own data and models to valuate risk. In this article, we take a Chinese life insurance company as an instance, selecting the treasury bonds, corporate bonds, securities investment funds and stocks as the research portfolio in investment risk. Then we use different types of GARCH(1,1) with skew student and normal distribution along with dynamic and static t-Copula and n-Copula model to measure the value at risk under different confidence levels and do backtesting in VaR. At last, we compare the result of these Copula models and find that the dynamic t-Copula performs better than others, therefore as the reference for the life company for further action in measuring Economic Capital.
