2、模型进行逐步的剖 析，得到 CAPM 最本质的研究对象：系数。从而将复杂的模型简化为对市场风 险系数的研究。在多尺度方面将日交易数据（收盘价）经多尺度变换得到对原 交易数据在多个尺度上的逼近， 并用来实证检验资本资产定价模型在中国证券市 场多个尺度上的拟合程度。本文详细介绍了资本资产定价模型参数及模型的建 立、基本假设和行为因素等，并在模型的基础上进行实证检验，选取沪市股票数 据进行汇总、分析、对比、计算，以验证该理论模型在我国证券市场的适用与否。 得出在中国股票市场上，标准的 CAPM 是不能与中国金融环境相适应的。 关键词：股票，资本资产定价模型，资产定价，实证研究 - II - ABST
