隨著社會與環境的快速變遷，政府傳統的單一權力控制模式已經無法有效解決公共問題與滿足民眾需求，因此世界各國政府改造趨勢多以治理取代過去由上而下的統治與管理思維，並且尋求政府體制以外的非政府夥伴加入公共事務管理與公共服務產出的行列，而公私協力治理模式之運作更是廣受學界與實務工作者的關注與重視。 本研究試以臺北捷運聯合開發制度檢視我國公私協力之運作執行，透過文獻分析與深度訪談，萃取相關學者與實務工作者的參與經驗，探討我國公私部門在捷運聯合開發之協力過程中所產生之限制與問題。 研究發現我國捷運聯合開發過程中的公私夥伴關係僅建立在制式化的契約基礎上，並無法有效回應開發作業所呈現的複雜動態變化，同時合作雙方也缺乏具體的協商機制與行為共識，因此本研究建議我國政府在政策規劃與設計階段必須將各行動者的參與動機和參與目的納入考量，同時在政策執行過程中，雙方亦須透過協商互動來確保彼此的合作意願，透過資源共用和權力互賴而完善我國捷運聯合開發之公私協力治理模式。 / With the social and environment rapid change, the traditional authority has been not solved the public problem. Hence, every country toward the governance to replace the top-down and seek for non-governments to be public administrators. Therefore, the Public-Private Partnerships is popular for scholar and practice workers. This study aims to review the Taipei Mass Rapid Transit(MRT) System with the respect of Public-Private Partnerships. We will discuss the Public-Private Partnerships’ limits and problem in MRT joint developments through the references and deep interview, gaining the experience from the scholars and practices workers. This study finds out that the Public-Private Partnerships in MRT joint development process are basic on the contracts. It could not respond efficiency the complex dynamic and both sides lack negotiation systems and arrangement at the same time. Consequence, the study suggests that the country have to consider the motivation and purpose from actors in the process of policy formulation. At the same time, both side have to ensure cooperation willing through the negotiation and to achieve the perfect Public-Private Partnerships through the resource dependence and interdependence of power in the MRT joint development.
