How did family characteristics affect women and men differently in self-employment participation in urban China? Analyses of national data show dual marriage penalties for women. Marketization made married women more vulnerable to lay-offs from state-sector jobs; their likelihood of being pushed into unskilled self-employment surpassed that of any other groups. The revitalized patriarchal family tradition favored men in family businesses and resulted in their higher rates of entering entrepreneurial self-employment. Married women who had the education to pursue entrepreneurial self-employment were constrained by family responsibilities to state-sector jobs for access to family services, and had much lower rates in entering self-employment.
