The older adults are important human resource. Grandparents providing care to grandchildren within the family is an important way to develop aging human resources, and has made signifi cant contributions to promoting female employment, improving birth policies and economic growth. Grandparents' care-giving, however, can also have positive or negative impacts on the physical and mental health of the elderly. On the basis of drawing lessons from foreign support policies for grandparents' care-giving, this paper uses the social policy analysis framework to discuss the implementation and research prospects of intergenerational care support policies. The study believes that the intergenerational care support policy should be incorporated into the overall solution of "the elderly and children issue" and policies related to aging human resource development. The study proposes that in the future, we should focus on further analyzing the economic value and cost of grandparents' care-giving, the social value and cost of grandparents' care-giving in a interdisciplinary perspective, and strengthen the policy research of grandparents' care-giving.
