摘　　要：基于"消费-年龄"曲线的生命周期特征,本文研究了寿命不确定条件下的个人账户养老金调整机制。首先分析了消费、死亡率与年龄的内在关系,构建了养老金调整模型,使"养老金-年龄"曲线与"消费-年龄"曲线相匹配,这不仅增强了养老资金的保障功能,而且可缓解人口老龄化对社会总需求的不利影响。最后,本文构建了具有政府补贴的养老金调整模型,在引致效应的作用下,可提高缴费用于支付养老金的比例,增强资金的使用效率。Based on the life-cycle consumption curve, we analyze the adjust- ment mechanism of individual pensions. Firstly, we find that the survival curve can describe the ＂consumption-age＂ curve, and construct the adjustment mechanism which can match the change of consumption with age. The new mechanism not only enhances efficiency of pension funds, but also alleviates the adverse effects of popu- lation aging on aggregate demand. Secondly, we analyze adjustment mechanism of individual pensions under government subsidies, and reveal its income effect and in- duced effect. More pension funds are used to provide pensions under the induced effect.
