| With the improvement of medical conditions and living standards,people's average life expectancy increases,leading to an increase in the number of elderly people.According to the United Nations age standard,by the end of 2018,the number of elderly people in China has reached about 250 million,and the aging situation is severe.Among them,the proportion of disabled and semi disabled elderly people is 16%of the elderly population,and the care of these disabled and semi disabled elderly people has become an important problem to be solved.At present,the development of social pension resources in China is limited,and influenced by the traditional concept of pension,family elderly care has always been the main mode of elderly care.This paper mainly discusses the influence of family elderly care on the labor supply of children.First of all,by using the method of literature research,this paper sums up the relationship between care style,caregiver role and family elderly care and children's labor supply at home and abroad,so as to obtain the general relationship between family elderly care and children's labor supply in academic circles at present.Secondly,the core concepts are summarized,and based on the labor supply model and human capital theory,the interaction mechanism between family elderly care,children's self-assessment health and children's labor supply is analyzed in turn,and the theoretical analysis framework among the three is constructed.On this basis,three research hypotheses are made:hypothesis 1 proposes that participation in family old-age care has an obvious inhibitory effect on children's labor supply behavior;research hypothesis 2 proposes that participating in family old-age care will reduce the quality of children's labor supply;research hypothesis 3 proposes that participating in family old-age care will reduce children's self-assessment health status,and then have a negative impact on children's labor supply.In order to verify the above research hypothesis,this paper uses Stata15.0 statistical analysis software to analyze and process the data of "China Health and Retirement Longitudinal Survey(CHARLS)" in 2015,and studies the direct influence of family elderly care on children's labor supply and the existence of children's self-assessment health intermediary effect by empirical method.In the process of studying the influence of family care for the elderly on children's labor supply behavior,the Probit model was adopted and its results were tested in four ways:Logit model is used to re-estimate;Eprobit model is used to deal with endogenous problems;propensity score matching method is used to solve self-selection problems;finally,the heterogeneity among different gender,age,education level and household registration is discussed.The results show that participation in family care for the elderly has a significant negative impact on children's labor supply behavior.The robustness test shows that the above conclusions are still valid.This conclusion verifies the validity of research hypothesis 1.In addition,the influence of family care for the elderly on children's labor supply behavior is observed from the perspective of difference:inhibitory effect of participating in family geriatric irradiation on female labor supply behavior is greater than that of male;participation in ?care for the elderly has a negative impact on women's labor supply behavior;it has a negative impact on children's labor supply behavior aged 25-34;and it has a significant negative impact on children's labor supply who have received junior high school and secondary school education;and the participation of rural household registered children in family care for the elderly will inhibit their labor supply behavior.In the process of studying the influence of family care for the elderly on children's quality of labor supply,the Ordered Probit model was adopted and its results were tested in four ways:Ordered Logit model is used to re-estimate;conditional mixing process method is used to deal with endogenous problems;propensity score matching method is used to solve self-selection problems;finally,the heterogeneity among different gender,age,education level and household registration is discussed.The results show that participation in family care for the elderly has a significant negative impact on children's quality of labor supply.The robustness test shows that the above conclusions are still valid.This conclusion verifies the validity of research hypothesis 2.Moreover,the influence of family care for the elderly on children's quality of labor supply is observed from the perspective?of difference:participation in family care for the elderly will significantly reduce the quality of men's labor supply,but has no significant impact on women;it has a negative effects on the quality of labor supply of children aged 25-34 and 45-54;it has a negative impact on the quality of labor supply of children who have received elementary education or below;and it has a greater inhibitory effect on the quality of labor supply of children in urban areas than in rural areas.In the process of studying the intermediary effect of children's self-rated health,the intermediary effect test model was used.The results show that children's self-rated health is a significant path of family care for the elderly affecting labor supply.This conclusion validates the hypothesis 3 of the study.On the basis of the research conclusion,this paper puts forward three countermeasures and suggestions from two aspects:alleviating the pressures of family care for the elderly and promoting employment,including improving the responsibility-taking system for the elderly care,improving the old-age service system and improving the employment capital of children,in order to realize the balanced development of family care for the elderly and the labor supply.The innovations of this paper are as follows:first,the perspective of the topic is novel and has theoretical and practical significance.At present,most scholars study from the perspective of caregivers,and some researches on caregivers are mostly from the perspective of women,with less attention to men;second,the robustness is tested by many methods,and the impact of family care for the elderly on the labor supply of children is studied from a variety of different perspectives,the choice of tool variables is innovated;third,we find a new significant path.However,in the empirical process,due to the limitations of the selected samples,the quality of labor supply is defined as ordered four classified variables,which is different from the general literature that treats it as a continuous variables,which may lead to a slight deviation in the empirical results. |
