At present，the heavy economic burden，the difficulty of early care of infants and young children，and the obstruction of women’s career development have become important factors affecting fertility and fertility intentions. In order to solve the dilemma of family childcare and improve the people’s willingness to have children，since 2019，the state has actively promoted universal childhood care offers and policies，a series of preferential packages for central and local policies，helping provinces and cities across the country to explore childcare programs with local characteristics. In recent years，Beijing has actively implemented the policy of encouraging the birth of three children and supporting measures，focusing on promoting inclusive childcare services. However，in general，there are problems such as insufficient total number of childcare services and coexistence of structural contradictions. This report is based on the current development status of early childhood care services in Beijing，and finds the difficulties and blockages in the development of universal and preferential childhood care services supply. This paper also puts forward corresponding policy reflections on the construction of an effective supply mechanism for universal and preferential early childcare services in megacity Beijing，during the “14th Five-Year Plan” period.
