治理性研究視角被廣泛的應用在檢視都市再發展或再生之政策、體制重構或空間規劃。不過目前以歐陸為主的治理性文獻，普遍缺乏對全球南方城市都市治理性形成及其特殊性的概念化，也忽略南方城市治理性形塑之動態、複雜或衝突的過程。作為台北都市計畫變革及歷史街區都市設計發展的關鍵案例，迪化街保存特區的治理性形塑過程之批判性探索，可補充上述研究缺口。透過對這一形塑過程的檢視，我們企圖描述一個異於歐陸治理性概念的演變。迪化街保存特區緣起於重新詮釋及再現其文化保存的政治合法性，企圖扭轉過去的政治正確及現代都市化下街區的負面形象。其後，我們將闡述在難以建構歷史街區「真實政權」及深入理解的狀況下，地方政府實驗「治理技術」的特殊雙重性：特區化實驗下計算性實踐及懸法特區的非數字治理，並論述其主要缺憾。

The research perspective of governmentality has been used broadly to review the policy agenda or institutional reconstruction of urban redevelopment or regeneration. However, the current European-focused governmentality literature generally neglects to conceptualise the characteristic, complex and conflicting process of shaping governmentality in Global South cities. As a critical case of reforming urban planning and experimenting urban design within a historical neighbourhood in Taipei, the process of constructing governmentality for Dihua Street Special Conservation Zone can help address this neglect. Through a critical review of such a process, this study aims to conceptualise an evolution process that is different from that of the European governmentality school. The formation of the Dihua Street Special Conservation Zone originates from reinterpreting and representing its political legitimacy of cultural conservation that seeks to reverse its past negative images to pursue political ‘righteousness’ and modern urbanisation. After this, due to local state’s difficulties of building the “regime of truth” and in-depth understanding of Dihua street, this study illustrates the special dualism and its core shortcomings of local state’s experiments of “technology of governance” via calculative experiments on a specializing zone and “governing without numbers” within a special zone of suspending part of planning regulations.
