中文摘要：

随着家庭结构与代际关系变迁,强化居家失能老人的非正式支持是社会政策的重要使命。利用2008年和2011年两期CLHLS数据的分析表明,子女经济支持对失能老人的居家照料及其费用具有重要影响。截面Logit模型显示,增加子女经济支持,老年人接受子女照料和社会照料的可能性会显著提高;面板固定效应模型揭示了子女经济支持从无到有,会使子女照料的可能性提高5.36%;子女经济支持每增加1万元,配偶照料的可能性将提高4.29%。Tobit模型表明,子女经济支持每增加1万元,照料费用增加125元;子女经济支持从无到有,照料费用提高58元。因此,子女经济支持对照料支持并未呈现＂挤出＂效应,而是进一步强化了子代对亲代的双重赡养责任。在相关政策的制定和调整中,需要关注代际支持,实现家庭资源的优化配置。

英文摘要：

With population ageing aggravated,the population of old people who are disabled and the corresponding proportion have increased rapidly.Due to a lack of formal care resources and an influence by the traditionally filial piety culture,most of old people with disability are still living at home and receiving informal care.Actually,adult children are the primary caregivers and financial supporters for their old parents.However,along with the changes in family structure and intergenerational relationship,are there any changes in the Dual Model,which means children provide both the finical support and informal care for their parents？Whether do the children reduce their direct care as a result of their increased financial support,and so whetherdoes the probability of being cared by other family members or social service providers increase？In addition,does capability of paying for informal care enhance as a result of a rise of financial support from younger generations？This study employed two waves CLHLS dataset collected in 2008 and 2011to analyze the impacts of financial support from children and corresponding changes in frail old people＇life in terms of receiving informal care and related costs.First,with data collected in 2011,we applied Cross Sectional Logit Regression Model to analyze the impacts of financial supports from adult children on informal care which are provided by children,spouse or social caregivers.Next,with the two waves＇data of 2008 and 2011,Panel Logit Fixed Effect Model was used to explore a causal relationship between changes in financial support and probability of receiving informal care.In terms of costs,this article adopts Tobit Model to explore the causal relations between financial support and the costs paid for informal care as well.The results of Cross Sectional Logit Model demonstrate the probability of receiving care from children and social caregivers dramatically increased if financial support provided by children improves,while controlling other variables.The results of Pen
