家庭规模缩小对家庭经济保障能力的影响:苏南实例

The Impact of Decrease of Average Family Size on Economic Security Capacity of Families:an Example in South Jiangsu

本文通过实验设计方法 ,并利用苏南农村居民的数据资料 ,分析实证了在有收入积累的前提下 ,家庭规模缩小不仅不会弱化家庭保障能力 ,而且会强化家庭保障能力。不同规模家庭保障能力差别 ,随时间推移和在家庭生命周期的不同阶段具有波动性。家庭保障能力会因家庭规模的大小、消费和积累模式的差异和在家庭生命周期中的不同阶段而不同 ,并可能发生相互转换。

Based on the data about the rural people in the South Jiangsu, this paper studies the impact of decrease of family size on the economic security capacity of families by using the method of model simulation. If income accumulation does exist, the decrease of family size will not weaken the security capacity of families, but strengthen it. The difference of security capacity due to different family size increases with the increase of consumption elasticity, while it decreases with the increase of risk occurring. And it also fluctuates at different stage of family life period. Family security capacity varies due to the differences in family size, consumption and accumulation pattern, and being at different stage of family life period.
