Previous Chinese literature on women’s hazards of giving births focused on the impacts of policies or marital and childbearing histories. Under low fertility regime, gender and intergenerational relations rather than policy interventions exert more influence on Chinese women’s childbearing behaviors. Under the framework of New Home Economics and gender equity theory, and gender and development approach regarding fertility, this study discusses about how Chinese women’s economic activities and changes in gender relations might affect women’s hazards of entering parenthood. Capitalizing on data from a longitudinal survey, this article uses event history analysis to test how housework division and wives’ economic activities influence the hazards of giving first births. The results suggest that women earning higher income tend to have lower hazards of giving first births. Coresiding with women’s mothers-in-law increases the hazards of entering parenthood. Also, husbands’ greater involvement in housework is related to higher hazards of giving first births, and this relationship is stronger in households that can hardly get help from womens mothers-in-law.
