The concept of intersectionality has been traveling globally from its origins in the US. The global adoption of this concept has not always paid sufficient attention to the differences in meaning for intersectional analysis and may too often adopt a simple translation of this idea as meaning “race，class and gender”. This paper distinguishes between two dominant models of intersectionality，the locational and the relational and uses a comparison of the different understandings of gender inequality in Germany and the US to show how the nationally institutionalized discourses of race and class inequalities in these contexts contribute to thinking about gender politics. The author believe，if dynamic intersectional analysis is extended to Chinese context，it will be great value and significance for the development of Chinese unique theoretical interpretation system.
