Social provision for women in the welfare system of Taiwan has been scarce since 1949. But the welfare provision for women gradually increased after 1987 when Martial Law lifted. However, this change formed a kind of sexual segregation in social politics. In the early 50s to 70s’, authoritarian system, men and women in Taiwan had a great discrepancy in their rate of social participation. Women's welfare issues were always decided by men. The gender ideology of equal treatment became mainstream in the political process of social welfare policymaking. After 1987, more female politicians entered into the political arena, but under the traditional paternalist male dominated political structure, the gender representitiveness cannot critically influence social politics, especially in regards to the passage of women' s welfare laws. In the most recent decade, more women have became involved in the political system and social organizations. Many social welfare laws have been passed by this lobby of those female politicians and social activists. However, these women and their organizations still have to play the traditional ideal women's role, in order to penetrate into traditional men's politics. It is a strategy and also a pitfall for women trying to influence men's politics in Taiwan. However, it has also resulted in the passage of several welfare laws for socially disadvantaged groups and unfortunate women.
