Abstract:Promoting family intergenerational support, creating a social environment suitable for the interaction of the elderly, and motivating the elderly to form a positive aging attitude to better improve their quality of life are of great signifi cance to the elderly, the family, and the society. Based on data of the China Longitudinal Aging Social Survey ( CLASS ) in 2014, this study explores the impact of intergenerational support and social networks on the quality of life of the elderly, and at the same time analyzes, from the perspective of aging attitudes, the intermediary mechanism of the impact of intergenerational support and social networks on the quality of life of the elderly. The empirical results show that the fi nancial support, life care, and spiritual comfort provided by children can improve the life satisfaction of the elderly. Of them, the spiritual comfort support is more important, which can signifi cantly improve the life satisfaction of the elderly. The elderly's positive social participation and interaction can also substantially improve their life satisfaction. Moreover, the economic support, spiritual comfort and social interaction of the elderly also help them set up a positive attitude towards aging. This indirectly improves their life satisfaction.
