Owing to the possible measurement error of variance and covariance for Markowitz's M-V model, in the present study, it employs two static models and two dynamic models, which are the sample covariance model, implicit factor mode!, implicit factor GARCH model and full-factor multivariate GARCH model.

基於Markowitz(1952)提出的M-V投资组合模型可能造成变异数及共变异数衡量的偏误，因此，本文以样本共变异数模型、内含因素模型等两我种静态模型，并参酌Alexander and Leigh(1997)的内含因子GARCH模型与Vrontos et al。
