The beginning of the 21 century witnessed the rise of the NGOs in China. Through the analysis of the three types of the NGO cases，this paper argues that the relationship between the NGOs and the government is in the deep and complicated transition. In the process of interaction，both sides depoliticized the NGOs’ activities and limit the interaction in the field of development and social welfare. Furthermore，the broker between the government and NGOs play an important tole for a good interaction. The expertise service and resource provision are the base of cooperation. However，patriarchy model of the state still dominate this field. It challenge the autonomy of the NGOs. In the long run，the good interaction provide the legitimacy for NGOs participation in the policy process of social welfare.
