臺北都會區大眾捷運系統，不僅是耗費數千億以改善都市移動困境的運輸 空間營造，還是負載與引發意義和想像的空間再現叢結；穿流其間的各種空間 操演，組織了新的都市經驗。本文挪用和改造Henri Lefebvre的空間分析三元論， 結合操演、網絡與節奏等槪念，提出一個分析架構來討論捷運系統作爲「美學 化之流動地景」的意蘊，以及牽涉其中的再現、認同與權力議題。 在具體分析方面，本文首先討論捷運經驗的論述中介，指明構成捷運論述 的三種主要機制：專家知識、媒體與通俗文化。其次，具體地解讀捷運流動空 間裡各種層次的再現叢結，釐析其支配性修辭所蘊含的美學化、視覺化與文本 化的權力運作和象徵營構。就此，本文特別討論捷運的高科技和自動化城市想 像的主題。第三，筆者轉向主體時空操演的面向，從幾個特殊切面探討捷運流 動經驗的繁複多樣，例如偏離與脫軌的操演、新節奏的產生和協商、與異己的 混雜相遇、慾望的想像和流動，以及異類身體誘發的緊張和排斥等等。最後， 本文思索流動與再現的主題所可能開啓的新思考方向。

The Taipei MRT is not only an expensive infrastructure for solving the urban transport crisis, but also a spatial-representational complex carrying and inducing meanings and performances which shape new urban experiences. The author appropriates and revises Henri Lefebvre’s framework of spatial analysis, combining concepts of performance, network and rhythm, then suggests that we view the MRT as an aestheticised landscape of flows of various textures of identity formations and power relations. The author first discusses three kinds of discourse - expertise, mass media, and popular culture - mediating the MRT experiences. The article then refocuses on the representational complex, demonstrating the aestheticisation, visualization, and textualisation of power relations implied in the symbolic construction of dominant rhetoric. Another issue concerning the spatial-temporal performance of subjects is also discussed in terms of norm-deviation, other-encountering, desire-imaginary, and body. Finally, the author explores the possible theoretical fields opened up by these issues.
