The Empirical Research on the Uncertainty and the Household Savings Rate in Urban China
利用2006年中国综合社会调查数据，研究发现收入波动显著提高城镇家庭储蓄率，而参与养老和医疗保险则显著降低储蓄率，且这种影响在不同储蓄率水平下存在差异。
This article defines the uncertainty of China's urban household in terms of the income volatility and participation of social insurance.Through the data from 2006 Chinese General Social Survey,we examine the relation between uncertainty and urban household savings rate.The results based on robust OLS and FGLS show that:there is a significant positive correlation between income volatility and urban household savings rate,and the participation of pension and medical insurance can significantly reduce the savings rate.Quantile regression results further show that:there is a significant positive correlation between income volatility and urban household savings rate on all quantile,and the strength of influence shows decline with the savings rate quantile rising. At the bottom of savings rate distribution,there is no significant relationship between the participation of pension or health insurance and savings rate,but at the top of distribution,pension and health insurance have significantly reduced urban household savings rate.
