应用缓冲储备模型实证检验我国居民的储蓄行为

通过应用缓冲储备模型，实证检验我国居民的教育、医疗、住房等开支的不确定性与储蓄之间的相关性，我们发现，我国居民的预防性储蓄行为不仅显著，而且以目标储蓄率为被解释变量的模型，能够比以储蓄水平为被解释变量的模型更好地解释我国居民的“预防性储蓄”动机。建立完善的医疗保障体系、改革教育体制是降低我国巨额储蓄的必经之路。

To Empirically Test the Chinese Saving Behavior by Using Buffer-Stock Model

By empirically testing with the buffer-stock model, the correlation between the uncertainty of expenditure in education, housing, and medical service and the savings for the Chinese, we find that the Chinese precautionary saving behavior is significant. Furthermore, our results also show that the precautionary saving motivation is better explained by the models with target ratios as the dependent variable than those with the saving levels as dependent variables. It is absolutely necessary to establish a sound medical protection system as well as to make further progress in education reforms so that the large size of our savings can be reduced.
