子代数量对农村老年人代际经济支持的影响--以亲子两代分居家庭为研究对象

子代数量与家庭支持力的关系是家庭研究中的重要问题。论文运用“中国健康与养老追踪调查”（ CHARLS）2011年全国基线调查数据，以亲子两代分居家庭为研究对象，通过非条件Logistic模型，分析了分居家庭子代数量对农村老年人代际经济支持的影响。结果表明：在控制其他变量的前提下，分居家庭中子代数量与农村老年人代际经济支持之间存在显著性相关。随着分居家庭中子代数量增加，农村老年人获得代际经济支持的递增概率存在着拐点。当分居家庭中子代数量上升至5个时，获得代际经济支持的概率最大。随着子代数量的增加，农村老年人获得代际经济支持的概率并非完全呈现正向递增的状态。

The Influence of the Number of Children on the Intergenerational Economic Support of the Rural Elderly:Parent-Child Separation Family as the Research Object

The relationship between the number of children and family support is an important issue in family research. With China Health and Retirement Longitudinal Study ( CHARLS) 2011 national baseline survey data, parent?child separation family as the research object, through non conditional Logistic model, it analyzed the influence of the number of children on the rural elderly intergenerational economic support. The results showed that there was a significant effect on the inter?generational economic support for the rural elderly with the other variables controlled, and there was a turning point in the influence of the number of separated families on the intergenerational economy of the rural elderly. When the number of children in the separation of the family rose to 5, it achieved the maximum probability of intergenerational economic support. With the increase of the number of children, the probability of the rural elderly to obtain the inter?generational economy was not completely presented a positive incremental state.
