摘要
储蓄是影响一国经济增长的重要因素,因此研究储蓄率的变化及决定储蓄的因素具有重要的意义。在影响储蓄的众多因素中,人口结构变化对储蓄和经济增长的影响越来越受到关注。上世纪70年代计划生育政策的推行和人口预期寿命的延长,加快了我国人口转变及老龄化发展的步伐。老龄化的发展必将改变居民的储蓄消费行为,影响储蓄—消费模式和储蓄率。老龄化对储蓄的影响具有不确定性,在经济发展的不同阶段,老龄化对储蓄的影响可能是积极的,也可能是消极的,老龄化对储蓄的影响具有明显的门限特征。
Savings is an important factor of a nation's economic growth Accordingly, it is of great significance to study the change of savings rate and its determinants. Among the factors, the impact of population structure on savings and economic growth has been drawing more and more attention. The implementation of the one-child policy since 1970s and increasing life expectancy has accelerated the pace of population aging which will in turn change the saving-consumption behavior of individuals and affect both the saving-consumption pattern and the savings rate. The impact of population aging on savings is indeterminate. It could be positive or negative at different stages of economic development. The impact of aging on savings has an obvious threshold effect.
