Abstract: As the aging of population is intensifying in China，elderly care has increasingly become a focus of social concern. A multi-dimensional analytical framework is constructed based on the family strategy；the IV-Probit model and the data of the Chinese Longitudinal Healthy Longevity Survey（CLHLS）in 2018 are used to explore how empty nest affects the elderly’s choice of institutional services. The research finds that empty nest significantly increases the possibility of the elderly choosing institutional care；for although the absence of children increases the opportunities for the elderly to obtain family economic support，it reduces the care and emotional support，thereby enhancing the willingness of the elderly to receive institutional care. Further analysis reveals that community-based elderly care services can，to a certain extent，replace the elderly care demands of institutions；the absence of children has a greater impact on aged people with economical independence；and the impact of daughter’s absence on the elderly’s choice of institutional care is more prominent than that of son’s absence. To better meet the diversified needs of elderly care，it is suggested to strengthen the supply of social elderly care services in areas with population outflow，promote the effective connection between family-based elderly care and social elderly care，and advance family policies based on gender equality.
