Abstract: The essence of contentious politics is interest appeal. The way of control and mediation may bury hidden trouble and promote the escalation of the struggle， while reforms can only temporarily relief contentions of certain fields and cannot achieve long-term effects. A larger and more inclusive governance structure is cooperation. The cooperative governance model still needs national control as a strong backing to realize the moralization of national power with a spirit of cooperation. Contentious politics starts from “expression” and “sonification”. Dialogue that effectively promotes communication becomes the key in pursuing justice and cooperative governance， but in terms of “personnel” and “topic” that could be allowed to participate in the “dialogue”，a specific range needs to be clarified. Contentious politics involves many irrational factors， and the thinking of “symbiosis and coexistence” becomes the basis of promoting cooperation and dialogue.

Key words: contentious politics; model of cooperative governance; dialogue mechanism
