公民网络参与正通过解构权力与信息来重构政策议程设置的主体关系，但无法避免传统参与困局的网络迁移与内生性议题偏向。本文通过公民网络参与介入的政策议程设置扩展模型与简化策略矩阵，从阶段过程视域与合作进化视域分析议程互动过程中的合作解是如何从合作不占优的传统议程设置环境中形成、析出并稳定进化的，认为政策议程决策主体单向主导到多元主体合作关系的逻辑变迁预示了绝对集权解体；网络参与搭建了议程设置的关系桥梁与持续性机制，追求占优回报的小合作政策共同体得以侵入不合作占优的议程设置环境中；不合作策略很难再侵入到合作环境，（高参与，高回应）博弈策略将演进为集体稳定的合作解。

Citizen’s Internet political participation is reconstructing the subject relationship of agendasetting through the deconstruction of power and information, meanwhile, the traditional issues got involved in the dilemma of internet migration and endogenous bubble is unavoidable. Based on the extension model of agenda-setting and simplifcation matrix of the intervention strategy, we analyzed the formation, precipitation and stable evolution of cooperation solution from traditional agenda-setting environment in which cooperation was not dominant in the process of agenda interaction. The results showed that logical change of the partnership from one-way leading to cooperation had announced a plural disintegration of absolute centralization. Citizen’s Internet political participation enhance the interaction of agenda-setting interaction. It is not easy any more for the uncooperative strategy invade into the enviornment of cooperation, and the strategy (high involvement, high response) will be the stable cooperation solution for a group-decisionmaking process.
