| 摘 要： | 整合市场风险与流动性风险有利于投资者全面管理风险，度量交易时所面临的风险。针对市场风险与流动性风险的时变性、异方差性和尾部特点，利用GARCH-EVT 方法进行建模。在此基础上利用三类二元阿基米德Copula 函数对两类风险的相关结构进行考察。结果表明:中国股票市场中个股的市场风险与流动性风险在上尾与下尾相关性加强，并具有对称性。基于上述相关结构特点对两类风险进行整合并利用VaR 模型进行度量，结果显示:该度量模型优于传统VaR 模型和不考虑两类风险相关结构的VaR 模型。

| Abstract: | The integration of market risk and liquidity risk facilitates the investors' comprehensive management of risks when they trade their stocks.Considering the time variation,heteroscedasticity and tail characters of market risk and liquidity risk,GARCHEVT method is used for the modeling of these properties.Three types of Archimedean Copula are used to investigate the dependence structure between two kinds of risks.The results indicate that the two kinds of risks show stronger dependence in the tails and the tw... |
