論文對現代資產組合理論與傳統資產組合理論分別進行了分析，並對兩者進行了比較研究，對馬克維茨的均值? ?方差理論從資產組合風險分散效應和最優資產組合選擇兩方面進行了重點分析，對資本資產定價模型、因素模型、套利定價理論進行了一定深度的分析和研究，對現代資產組合理論的前提假設? ?有效市場理論及在對有效市場理論和資本資產定價模型形成挑戰和質疑背景下提出的行為金融理論進行了論述，論文最後分析了現代資產組合理論在我國的研究及其應用的廣闊前景。 -
On the one hand, the author discusses markowitz ' s mean - variance portfolio selection model, single - index portfolio selection model, and simplified model of optimal portfolio selection. at the same time, based on the rules of optimal portfolio selection and other risk - metric indices, the author also discusses mean - absolute deviation model, mean - semivariance model and mean - value at risk model. on the other hand, the author discusses the asset pricing model, including the capital asset pricing model ( capm ), the multi - factor asset pricing model, and the arbitrage pricing model ( apt )
一方面，作者討論了馬科維茲的均值-方差資產組合選擇模型、單指數資產組合選擇模型、最優資產組合選擇的簡化模型，同時根據最優資產組合選擇原則和其他風險度量指標，討論了均值-絕對離差、均值-半方差和均值-風險價值資產組合選擇模型；另一方面，作者討論了資產定價模型，包括多因素資產定價模型和套利定價模型，特別是在四種因素變量的基礎上，探討多因素資產定價模型。 -
