First of all, the evolutionary game model of this system is built, according to a population and determinately dynamic function in evolutionary game theory, and quilibrium structure and effect factors of the evolutionary system are analyzed. Next, the evolution quilibrium characteristics of investor behaviors in China's securities market are researched as a demonstration, and the reasons why noise traders become popular in the process of investor behavior evolution are explained, based on its evolutionary mechanism. Moreover, the influences of investor behavior evolution on share market's fluctuation are researched through setting up its noise trade model. When noise traders are dominant in securities market, price discovery function and resource configuration effect are also analyzed. Finally, when noise trade become popular, the shortage of some policies, such as, enlarging institution investor and short sale is explained, and some good suggestions are provided according to former research results.

首先，应用进化博弈论中的单群体确定性模仿者动态方程建立证券投资者行为的进化博弈模型，并对进化系统的均衡结构特征及其影响因素进行分析；其次，根据我国证券市场实际，对我国证券投资者行为进化的均衡结构进行实证分析，并从投资者行为进化的角度，解释我国证券投资者行为进化为噪声交易主导市场的原因；然后，通过建立股市波动的噪声交易模型，研究投资者行为的进化对股市波动的影响，并进一步分析我国噪声交易主导市场时对市场价格发现和资源配置功能的影响；最后，根据理论及实证的研究成果，分析噪声交易主导市场时大力发展机构投资者等制度作用的有限性，并进一步提出我国证券市场相机治理的政策建议。
