Based on the survey in Hangzhou in 2011，this paper analyzes the urban integration of young migrant workers from the economic，social and psychological perspectives. The survey finds that，for young migrant workers，their employment industries are relatively concentrated；they have higher education level than old generation；but still have lower income level. They are not very active in community participation；the social support mainly comes from informal system；they have better life satisfaction，but still not satisfied with the status；they have ambiguous self identity and strong intention to stay in City；generally speaking，they have positive cognition on their own situation，but also have feeling of relative deprivation.
