the important role of social organizations in participating in children’s undertakings and actively providing public services have been highly affirmed in a few Beijing’s social development plans within “14th Five-Year” period. Focusing on the goals of “care for newborns，education for young children，support for the weak” and other livelihood security goals，various professional social work institutions，foundations，legal institutions，charities and voluntary service organizations in Beijing participate in the provision of social public services for children in 2021. A number of influential social service brand projects have been formed in response to the urgent problems faced by children’s social education and community support. In the delivery of social public services，there are still challenges in which the interaction and complementation mechanism between the government and the society is not perfect，the government purchases social organization services without corresponding service standards，and the ability to respond to the special needs of children in distress is relatively weak. There is an urgent need to optimize the participation channels and supply quality of social organizations in children’s social public services，and provide high-level guarantees and high-quality services that reflect the “first-class standard” of Beijing as the capital of China.
