In order to explore the relationship between supply and demand of universal childcare services under the background of the three-child policy, data were obtained through questionnaire and field survey. Kruskal-Wallis test statistics and Logistic regression model were used to analyze the data. The results show that: the development of childcare service and the implementation of fertility policy complement each other. At present, the supply of childcare services is still insufficient, and universal childcare is the development direction of the industry. The government should increase the investment in universal childcare service to increase the vitality of the market. Encourage social forces to participate in the provision of childcare services, promote public-private cooperation, and jointly promote the development of inclusive childcare services.
