本文旨在檢視微博型網路社會下中國大陸網民的集體行為，藉由探討「郭美美事件」此一具公共權力監督代表性之網路個案，研究發現事件發展中產生政治權威管制下的網路民粹反彈，以及網民不滿情緒的圍觀化發洩，加上多元網路輿論的推波助瀾，交織成一個以議題核心具層次的「相互監控監獄」網路社群傳播結構。而這種網民將不滿情緒在網路空間中熱烈發酵的群體傳播現象，與嚴格網路管制恰形成對比，但卻也顯示公民社會的理想境界實踐仍有段距離。

By examining the Guo Meimei case from the viewpoint of public surveillance, this study aims to examine the populist phenomenon of weblog society in China. After tracking the development of the case, we found that populist netizens express a backlash against regulation by the political authorities, and release their feelings of dissatisfaction on the net. Additionally, the populist phenomenon creates a ＂synopticon＂ communication framework, which can be regarded a social network of an ＂issue-centered＂ style. The paper also shows that there is still a long way to go before the ideal of civil society can be realized in China.
