| Population aging is a global trend,China is also facing aging problems.Active aging strategy is a significant national strategy coping with population aging.It not only emphasizes the objective needs of the elderly in material aspects,but also emphasizes the psychological health pursuit of the elderly.Intergenerational care is a kind of behavior that grandparents help to care for grandchildren in order to reduce the burden of their children.With the rapid development of urbanization and the further introduction of the “three-child”fertility policy in China,intergenerational care will be more common among the elderly,and more middle-aged people have joined the army of intergenerational care.Taking care of grandchildren will take up the time of their ancestors and consume their energy.In this case,the care behavior of grandchildren will have a certain degree of influence on the subjective and objective health status of the elderly themselves.Life satisfaction is the evaluation of life state of middle-aged and elderly people,which can effectively reflect the quality of life of the middle-aged and older.Under the background of population aging,combined with the current situation of inter-generational care in China and the practical needs of pension,this paper focuses on the middle-aged and older aged 50-80,studies the impact of intergenerational care behavior on life satisfaction of middle-aged and older,and increased national,social and family attention to middle-aged and older persons in alternative care.This paper selects the data of the 2018 China Health and Retirement Longitudinal Study as the research data,and selects the control variables from the individual,family and social levels.They are demographic characteristics of gender,age,urban and rural distribution,education and marriage,personal health characteristics of chronic diseases,self-assessment of health and sleep duration,social and economic characteristics of work,social activities and social insurance participation,and family characteristics of children’ s economic support and living conditions.This paper uses Stata16.0 software for empirical research to explore the relationship between the participation of middle-aged and older in grandchild care and their life satisfaction.Firstly,the propensity score matching method is used to solve the endogenous problems that may exist in the participation of elderly people in alternative care,and then the Ordered Probit model is constructed for basic regression.Secondly,this study uses binary Logit model to test the robustness of the basic regression results by changing the dependent variable that is the assignment of life satisfaction.Finally,the middle-aged and the elderly were divided into groups according to the differences of urban and rural areas,age and gender,and the Ordered Probit model was used for regression again to further study the differences of the impact of caring for grandchildren on the life satisfaction of the middleaged and older.Through empirical analysis,it is found that act of taking care of grandchildren from generation to generation generally improved the life satisfaction of middle-aged and older.At the same time,the positive influence of grandchild care on life satisfaction of rural middle-aged and older is more obvious;the positive impact of act of taking care of grandchildren from generation to generation generally on life satisfaction among middleaged people aged 50-59 is more pronounced;the positive influence of grandchild care on life satisfaction of female middle-aged and older is more obvious.Based on the above research results,this paper offers relevant advisable recommendations to improve the life satisfaction level of middle-aged and elderly people who take care of grandchildren from three aspects of government,society and family,and hopes that this study can enrich the positive aging strategy in China. |
