都市更新是一種土地產權整合與開發利益分配的過程，也是需要集體行動才能完成的行為。本研究關注於都市更新中，集體行動困境如何破除，使都市更新參與意願整合工作順利推動。據此，本研究以集體行動理論及信任理論為研究立論基礎，選取台北市木柵地區「國立政治大學北側更新示範地區」作為案例地區，採問卷調查法以當地居民為抽樣調查之對象，並採用因素分析與結構方程模式作為資料分析方法，以更新認知、社會網絡、實施者信賴、都更整體信任程度與參與更新意願為五大潛在變項進行結構模式驗證，驗證結果發現都更整體信任程度對於參與更新意願具有正向直接影響，更新認知、社會網絡與實施者信賴三者對於都更整體信任程度亦有正向直接影響關係，其中又以實施者信賴為影響居民都更整體信任程度之最重要因素，並具有更新認知與都更整體信任程度間中介效果。
