臺灣都市更新空間治理之變遷與困境

Evolution and Dilemmas of Urban Renewal Spatial Governance in Taiwan

臺灣都市更新推動從側重層級治理（Hierarchical Governance）模式的傳統都市計畫，已拓展至具有市場治理（Market Governance）及網絡治理（Network Governance）模式相關制度的《都市更新條例》。該法治理模式比《都市計畫法》更多元，但空間治理成效卻面臨案件規模小、區位零散的困境。本研究認為都市更新制度變遷曾歷經「再尺度化（Rescaling）」，並建構出「全市尺度（City Scale）」、「地區尺度（District Scale）」及「單元尺度（Unit Scale）」的多尺度空間治理框架。然而碎片化的空間治理困境，導因於制度變遷過程中，跨各尺度間（Inter-Scalar）的治理機制未能健全。雖有「混合治理（Mixed Governance）」的多元治理設計，卻過度集中於「單元尺度」。對於「全市尺度」及「地區尺度」的空間治理安排上有所缺漏，以致都市更新空間治理陷入缺乏計畫性（Planning）與整體性（Consistency）的困境。

The institutional framework for promoting urban renewal in Taiwan has evolved from the traditional urban planning model focused on hierarchical governance to the Urban Renewal Act, which incorporates mechanisms reflecting market governance and network governance models. The governance models of the Urban Renewal Act are more diverse than those of the Urban Planning Law concerning urban renewal, yet they face the challenge of small-scale projects and fragmented locations in terms of spatial governance effectiveness. The study's findings indicate that institutional transitions in urban renewal have undergone“Rescaling,”resulting in the establishment of a multi-scalar spatial governance framework encompassing the“City Scale”,“District Scale”and“Unit Scale”. However, the fragmented spatial governance dilemma arises from the inadequacy of inter-scalar governance mechanisms during the process of urban renewal institutional transition. Although a multifaceted governance design of“Mixed Governance”has been implemented, too much attention has been put on the“Unit Scale”. This neglects spatial governance arrangements at the“City Scale”and“District Scale”, which tends to cause a lack of planning and consistency in urban renewal spatial governance.
