摘　　要：本文对提供最低提取利益保证的变额年金保险进行了深入分析,总结了最低提取利益保证的主要特征(重置条款、奖励条款、惩罚条款),并将这些特征进行了定量的分析。本文在Daniel Bauer等(2006)提出的定价模型的基础上进行了创新和改进,在定价过程中加入了国外年金市场上通行的最低提取利益保证的三大主要特征,研究出一套可操作性较强的定价方法,旨在为将来国内保险公司设计开发此类产品时,提供一些建议和理论指导参考。China has launched a pilot project on Variable Annuities since May 2010, trying to enrich the product mix and establish a multi-level product structure to cater to the need of different levels of consumers.
