夫妻议价能力差异对农村老年父母照料行为的影响——基于CHARLS数据的实证研究

Analysis on the Effect of the Difference of Couple's Bargaining Power on the Caregiving Behavior to Their Old Parents——Empirical Evidence from CHARLS Data

为了全面了解夫妻议价能力差异对农村老年父母照料行为的影响,借助纳什议价模型,利用2011年中国健康与养老追踪调查全国基线数据,运用Probit和Tobit模型进行实证分析。研究结果显示:(1)夫妻在家庭资源分配上不仅存在相对权利的较量,还存在偏好差异。随着妻子教育水平、经济水平的提高,妻子更倾向于向亲生父母提供时间照料;(2)父母辈的社会地位和经济差异对于成年子女夫妻家庭资源分配的影响不容小觑。(3)姐妹的替代照料可以有效减轻夫妻对于双方父母的照料责任。研究结果能够让我们更加了解成年子女夫妻之间的权利互动模式,进而能够宏观地了解我国农村家庭养老问题的全貌。

Based on the latest China Health and Retirement Longitudinal Study（CHARLS） survey data and employing Nash bargaining model, this paper examines the effect of the difference of couple＇s bargaining power on the caregiving behavior to their old parents. Three main findings are as follows： First, the relationship between couples and elderly parents is indeed affected by different kinds of bargaining power. If the wife＇s education or occupational status is higher than the husband＇s, the wife may transfer more time to her own parents. On the contrary, the result is more complicated for husband. Second, the status between parents and in-laws also influence the allocation of family resource. Third, consistent with the gendered nature of parental care, a sister＇s likelihood care can decrease the couple provided care. This study can make us have a better understanding of the course of family decision.
