In China,social management model on migrant workers now is undergoing four transitions:the management goal is changing from planned regulation to promoting integration,the object is from invader to neo-residents,the pattern is from working each for himself to coordinated management and the means is from restriction to service.However,due to the misunderstanding between city and rural areas,the dual decollated system between them and the immature social management mechanism of migrant workers,such transition is confronted with a lot of dilemma.This paper finally put forward such suggestions on how to innovate social management model on migrant workers as promoting the communication and integration between residents and migrant workers so as to innovate the management value,breaking the situation that runs the rural and urban society in different ways so as to eliminate the institutional discrimination against migrant workers and integrating resource so as to construct a permanently effective social management mechanism on migrant workers.
