To solve the limitations of the variance of marketable securities′ revenue rate as the investment risk measured in Markowitz′s model (MV), based on the concepts of entropy and cross-entropy, the measurement method of risk is put forward with entropy and cross-entropy on the basis of studying the MV model.
为了解决马科维茨(Markowitz)模型中以证券收益率的方差测度投资风险的局限性,基于熵以及差熵的概念,在研究其均值方差模型的基础上,提出用熵和差熵来作为风险的度量方法,从而建立了几种关于熵的证券投资组合优化模型,使对证券投资组合模型的研究和应用更加合理、客观。
