Among affluent industrialized nations, the United States provides the fewest rights and benefits for women. While previous literature focused on examining gender ratios in every aspect of the labor market and exploring the relationship between the ratio of female representation and benefits, this study chooses an active representation approach that goes beyond describing gender equality. In this study, LISREL model statistical analysis is employed to examine the structural relationship between women's political and economic power, policy performance and social security in the United States. Concretely, major findings are: (1) women's economic power promotes better welfare policy performance for women and enhances the political power of women, but exerts an indirect effect on their social security; (2) though the political power of women has a direct, but slight, effect on their social security, better effects may be obtained through more effective performance of welfare policies.
