摘 要

根据博弈论观点，证券投资市场不论处于低效或高效的状态，均是证券投

资参与者博弈市场的结果.但是在现实的市场中，博弈双方并不知道对方参与资金额度的介入时间、程度的范围、持仓的成本等等，所以会导致投资者只会在各种不明确的背景下进行博弈.在我国证券市场上，其本身只是一个不完全对称信息的博弈市场，本文就是要把博弈论的相关理论引入到我们国家证券市场，以博弈理论作为最主要的分析工具，把握市场上各参与者的博弈特征，分别在不对称信息条件下，从个人的投资者和机构的投资者的不同角度通过建立起静态的和动态的博弈模型，去研究双方投资行为策略，进而找出来影响策略变动的原因.在证券市场上只有进行公平的博弈，才能够去促进提高相关收益、提升运行效率.所以，从不同投资者的决策行为角度出发，运用相关的博弈论作为分析基础，借鉴和发扬目前国内外有关学者关于在金融市场的研究案例及总结结果，去揭示我国的证券市场上的存在的经济现象，并通过对个人投资者的从众行为的研究，以及对机构投资者的坐庄行为的考察，去揭示信息重要性成都，这也正是这篇论文需要研究的最主要的目的.并最终得出结论：只有支持开展机构投资者的基础上还应当要加强管理，并为证券市场的投资实践活动提供了决策依据，对切实保护个人投资者具有现实指导意义.
