Using data from “The General Survey of Chinese Social Status” conducted in 2015，this study tries to analyze the new-generation migrant workers' political participation . We try to compare the new-generation migrant workers with old-generation migrant workers and new-generation urban labor force，and analyze the internal difference among the new-generation migrant workers. According to the findings，comparing with the old-generation migrant workers，the new-generation migration workers have lower enthusiasm for participating in grossroots democracy；comparing with the new-generation urban labor force，the new-generation migrant workers have some shortages in capability and knowledge regarding political participation，and their participation interest is also lower. Moreover，regarding the political participation behavior，the new-generation migrant workers are relatively more inclined to adopt the non-routinized and non-institutionalized mode.
