中文摘要：

本文在一揽子期权（Basket Options）定价理论的基础上，对期权的标的价格引入跳跃一扩散过程进行建模，用几何布朗运动描述其动态变化过程，用Possion过程刻画资产价格受新的信息和稀有偶发时间的冲击所发生跳跃的计数过程，用对数正态随机变量描述跳跃对应的跳跃幅度，有模型限定下，运用Ito-Skorohod微分公式和等价鞅测度变换，得出加权算术平均价格一揽子期权的一个推广的解析定价公式。

英文摘要：

The article establishes the model of Jump-diffusion for pricing of option, based on basket options pricing. The article uses GBM to describe its dynamic process and Possion to demonstrate the counting process of jump of capital price under the effect of new information and accidental events. The article uses log-normal random variables to describe the jump range. Under certain model, the article gets a general pricing equation of basket options based on weighting arithmetic average price by It-Skorohord differential equation and equivalent martingale measure.
