Abstract: With the market-oriented reform in economy and the change of administrative mechanism in politics in China, the seperation between the State and the Sociey comes into being. During the fast development of kinds of NGOs, the state power begins to transfer to other poles, which may promote social mobilization in China. Due to the administrative control and the legal constraint, the actual mobilization action transfers to mobilization on Internet, which may offer less political cost, spread fast and be overseen difficultly. As the important organizations in the civil society, the Chinese NGOs push and promote the social mobilization on Internet through making influence on the government policy, mobiling the public, and allying with other organizations. On the other hand, due to the shortness of the Internet application and self-governance ability, the function of the Chinese NGOs in Internet mobilization should not be exaggerated. The Chinese NGOs should build a more effective self-governance, if they want to make a deeper influence on Internent. Facing to the functions of the Chinese NGOs on Internet, the government should turn into Public Governance Model in order to make a reasonable response.
