Abstract: Changes in people's marital and fertility intentions and behaviors play a significant role in declining fertility rates. Based on data from a specialized survey, this paper investigates the intentions and determinants of marriage and fertility within distinct childbearing-age groups, concerning non-marriage or delayed marriage, childlessness or delayed childbearing, and low fertility, under the background of current fertility policies. It finds that the majority of individuals in these groups still wish to marry and have children. The main reasons for the divergence between their intentions and behaviors are the rising costs of marriage and childbearing, including economic and time costs. Furthermore, the impact of cultural and public opinion cannot be overlooked. Regarding the Three-child policy and supporting measures, over twenty percent of the married respondents consider them effective in boosting childbearing intentions. Reducing educational costs, providing child-rearing subsidies, and ensuring parental leave are the common policy demands. Therefore, it is crucial to reduce the costs of child-rearing for families through diversified economic support, establish a comprehensive lifecycle marital and childbearing support policy system, and convey positive marital and childbearing concepts through cultural development.
