This article reviews and analyzes the studies conducted by European and American scholars regarding the issue of intergenerational care reflecting the general features and situations of the intergenerational care in these advanced industrialized countries. On the basis of it, this study extends the scope of these studies to the fields of social policies and social support to family care, and reveals the inspiration of these experiences to the Chinese readers to think on the issues. In China, the increasing number of left-behind children, the elderly of rural areas, the shrinking size of urban families, and the shortage of public care resources for admission of children at the daycare centers, all reinforce the need for an understanding of the nature of the grandparents' care. However, most researchers in China are not familiar with the theoretical hypotheses and research methods for the study of intergenerational care, even ignoring this discourse. For all these reasons, it seems necessary to learn the international experiences in order to deepen our understanding of the related issues. This study will explore the theoretical premise and analysis of the framework of the conception of intergenerational care through a method of literature review reflecting the current situation of intergenerational care in European countries. The study evaluates the conceptions in the context of the production and reproduction system, and also, concludes the ways of research among these articles, including the use of statistical analysis based on survey database; discussing the effects of intergenerational care on the physical and mental health of the child development, and the quality of life approach of the elderly as the caregivers. As a result, studies of these literatures provide thought and nourishment for our thinking about social policy regarding this issue. It shows that this type of family care does not disappear in the advanced industrialized countries after deteriorating the family functions and the development of the public service system. The influencing factors of intergenerational care are not only cultural but also related to the social systems of production, reproduction, and social policies. In the end, the implications of these studies for the Chinese readers are assessed, emphasizing that the support of social policies has a positive effect on the social welfare of grandparents and grandchildren, and advocates the adoption of policies and service measures to support the alternative care for the elderly.
