摘　　要：在结构化模型下,考虑标的资产的红利收益及企业债务为确定和随机两种情况,采用鞅方法得到有信用风险的连续几何平均亚式看涨和看跌期权的定价公式。且公式具有Black-Scholes平价关系。Under the structural model, we consider the dividend of underlying asset and the two cases of enterprise liability,whlch is definite or stochastic. By applying equivalent martingale measure transformation, we derived the pricing formula of default continuous geometric average Asian option,and the formulas have Black- Scholes parity relation.
