引入人口结构和社会保障因素的中国储蓄率模型

Attracting population structure and social guarnatee factor's China saving mode

在对国民储蓄率的影响因素进行分析后,对经典的生命周期模型进行了拓展,引入了人口结构和社会保障两因素,从而构建了一个新的生命周期模型。在此基础上,对我国的国民储蓄率进行实证研究后发现,我国的人口结构确实会对国民储蓄率产生较显著的影响,而社会保障水平却对其影响不显著。

After analyzing the factors that affect th e national save rate,we extend the classic Life Cycle Model and introduce two important factors,i.e.,population structure and social security,therefore,a new Life Cycle Model was constructed.On the basis of that,empirical study of Chinese national save rate is done,and we find that population structure,indeed,has a significant effect on Chinese national save rate,but it’s not true for the social security level.
