摘 要
随着社会的繁荣进步,金融市场也不断发展和完善，并在国民经济生活中扮演着越来越重要
的角色。金融市场的运作显示出极大的随机性，因而随销售案例
机微分方程理论在金融产品定价方面
有很好的用武之地。所以将随机微分方程应用于金融领域是最近几年的1个热门话题。
本论文即是对这种应用进行探讨。技术上的思想主要是将连续过程的随机微分方程离散化来
进行研究。具体使用数学建模的品茶的诗句
方法，以随机微分方程的有关理论和金融市场理论为主要工
具研究了金融市场有价证券、股票以及股票期权的定价及相关内容，得出了相应结论以及债
券，股票，股票期权价格的计算表达式，并对股票的随机价格模型符合 几何布朗运动模型
给出了详细严谨的数学证明过程。最后分析了本研究领域现存内蒙代东致辞简短
的问题，预测了本领域研究的
发展方向。
