摘　　要：假设标的资产价格服从均值回复过程,运用矩匹配技术,研究Hull-White模型下商期权定价问题。相比于使用蒙特卡罗模拟方法,对Hull-White模型采用矩匹配的估值方法,可以在确保精度的基础上显著提升商期权定价的稳定性和效率。最后,在中国股票市场上,选取2个行业龙头公司的股票作为研究对象进行实例应用,评估期权定价模型在金融市场的适用性。结果显示,本模型与蒙特卡洛模拟方法的估计结果差异极小,但前者用时显著缩短。Under the assumption that the underlying asset price follows the mean reversion process,the quotient option pricing problem under the Hull-White model is studied by using the moment matching technique.Compared with the Monte Carlo simulation method,the stability and efficiency of quotient option pricing can be significantly improved by the proposed valuation method,while maintaining accuracy.Furthermore,in the Chinese stock market,the stocks of two leading companies are chosen as research objects for evaluating the applicability of the option pricing model in the financial market.The results indicate that the estimation results of this model and the Monte Carlo simulation method exhibit minimal differences,althougth the former requires significantly less time.
