本研究從複雜性理論的作用者探討社子島開發案，將社子島開發案之作用者分為政府官員、政治人物、專家學者、企業廠商及在地居民五類，對社子島土地開發案進行分析社子島開發案的爭議原因、社子島開發案的實況、以及臺北市政府對於社子島開發案一事無成之原因，並提出建議。為期全面深入分析社子島開發案，本文使用文獻分析法與深度訪談法，以探討社子島之社會作用者關係。本研究發現：臺北市政府未著重社子島開發案的作用者、未能掌控社子島開發案有作用者之間的互動過程、未具體掌握社子島開發案作用者自有的私利、未形塑社子島開發案當地居民熱忱與共同利益。本研究建議：針對五類作用者個別方式處理社子島開發案加以追蹤、針對主導作用者之間的互動做進一步釐清、如何誘導作用者之間的互動進展，使從分裂與矛盾的自我利益叢結脫身，到公共利益之建構。

This study explores the agents in the local governance of the Shezidao development project with the perspective of the complexity theory. In this case, the author divides the agents into government officials, politicians, experts and scholars, enterprise manufacturers, and local residents in five categories. The author analyzes the reasons for the controversy surrounding the development of the Shezidao project, and the reasons why the Taipei City government had failed in the development of the Shezidao project, and makes recommendations. With the literature analysis method and in-depth interview method, the author explores the relationship among these agents in the Shezidao development project. The study finds that Taipei City Government did not focus on these five categories of agents, failed to try to control the interactive process among these five categories of agents, and did not specifically grasp each self-interests of these five categories of agents, and did not shape the local residents’ enthusiasm and common interests in the case of the Shezidao Development Project. The author proposes to track their claims of these agents on the development of the Shezidao development project, to further clarify the interaction among these agents, and to induce their interaction from the contradiction of self-interest to the construction of public interest.
