组群视角下的收入分配对居民储蓄率的影响分析

Income Distribution and Residents' Savings Rate: a Theoretical and Empirical Test Based on the Perspective of Income Group

收入分配对居民储蓄率具有重要影响作用,但以往研究未能有效深化两者的内在机制。尝试从组群视角将居民群体按照收入标准划分为高、中、低三个收入群体,并以三类群体的各自储蓄率结合他们对应的人口权重的计算方法来衡量居民储蓄率,使收入分配内生化,并深化收入分配与居民储蓄率间影响和传导机制。在此基础上结合我国历年的经验证据对收入分配和居民储蓄率两者关系加以实证检验,结果显示出:收入分配差距越大,越易导致居民储蓄率的走高;而收入的增量影响对居民储蓄率作用不大。

The income distribution has an important influence on the residents＇ savings rate,but the previous studies have not been able to deepen their internal mechanism. This paper attempts to divide the population into the high,medium and low income groups which is based on the income standard from the perspective of income group. Combining with the respective savings rate and the population share of three kinds of groups,we measure people＇s savings rate,then make the income distribution endogenous,and deepen the transmission mechanism between the income distribution and the residents＇ savings rate. On the basis of the empirical data in China,the paper makes an empirical test on the relationship between the income distribution and the savings rate,we found that the larger the income distribution gap is,the higher the savings rate is. Meanwhile,increasing the income make no sense in the residents＇ savings rate.
