Meanwhile, with the promotion of living standard, Chinese people grow more aware of their living environment and civic rights, which leads to more and more mass protests of NIMBY. Usually the NIMBY protests in China turn into NIMBY conflicts at last. How to resolve the NIMBY conflict not only highlights the public management ability, but reflects the complex interactions of politics, economy, culture and social psychology. Recent evidence and related literature research indicate that new public involvement in the process of NIMBY is a central concern for the NIMBY conflict resolution. In China, how people participate in the process of the NIMBY conflicts and how the participation processes frame? Do the framing processes of new public involvement encourage the NIMBY conflicts? Answering these problems is of great significance to China's NIMBY conflicts resolution, especially through new public involvement to relieve the symptom of NIMBYism?  Case studies of protest against waste-burning plants in Guangzhou, Beijing and Hangzhou indicate that the framing process of NIMBY conflicts in China is a protesting interaction mainly between ″government″ and ″residents.″ The processes are constituted by 4 stages: issue formation — dispute continued — mass protest — situation calmed down, during which, residents are eager to participate in the NIMBY policy process accompanying the structural encouragement of participating in the collective action. Lack of public participation during the process of conflict is serious. The analysis of the framing process of new public involvement in the NIMBY conflict shows that peoples' strong requirements of participating and the serious situation of lack of participation encourage mass protest of NIMBYs. Public participation is affected by peoples' risk cognition, credibility gap, information communication, local attachment, technology insurance, problem transference, community resources, etc. In the 4 stages of the NIMBY conflict, local residents experience a process of ″becoming aware, interpreting, evaluating, decoding and acting,″ and the whole framing process of public participation is a problem-exaggerating and negative-decoding process. The political elites, action leaders and opinion leaders who promote and encourage people to participate in the collective actions have been involved in the core issues. Next, residents have been monitored by the ″victim sense″ and usually view the NIMBY problem as a problem of ″safeguarding of legal rights.″ Through communicating and discussing on the Internet, it's facilitated for residents to get consensus quickly and initiate mass protests soon. There are many reasons that impede peoples' rational behavior in the mass protests of NIMBY, such as cognitive liberation versus asymmetric information, strong requirements of participation versus out-of-order organization, covering up the facts versus requirements of civic rights, credibility gap versus knowledge monopolization, in the name of justice versus pursuit of personal profits, and so on. So it's necessary to promote new public participation to overcome NIMBYism and to realize the real participation by expanding institutions of collaboration and dialogue.
