Recently the number of single mothers is increasing more and more in Korean society. However government have difficulty in making policies for them in the absence of coherent welfare paradigm. So, this article aims to understand single mother`s various difficulties and to help to make a integrative welfare paradigm. Single mothers suffer from economic, cultural, and political equalities in Korean Society They are marginalized in gender-differentiated labor market, meanwhile are in difficulties for tension between paid workers and nurturers. Also they are regarded as inferior, deviant, and immature people under the androcentric mainstream discourse. And they are excluded in making welfare policies decisions directly related in their lives. So welfare policies for single mothers treated them as the undeserving poor, and produced ``generative welfare``, ``workfare`` paradigm. According to the paradigm, they and their children are provided the minimum welfare and social stigma of ``welfare mother``. Therefore alternative welfare paradigm needs to integrate single mother`s multidimensional demands in a standpoint of social justice rather than a benevolent standpoint. Furthermore this article will help to enrich debate on welfare and single mother`s issue in Korean Society.
