Abstract
The research uses a comparative analysis framework to interpret the multiple commodification processes for the working poor, which consists of research tropisms from a macro-sight system and from the internal mechanism and proceeding course of the social security system. Based on this framework, the authors try to establish an ideal type with a universal explanatory power to reveal the impact of cross-national diversity on social security systems in the decommodification process among poor female workers. The research also examines the extent to which such differences ever existed between Belgium and China in empirical terms.
