以都市指標系統談台北市之永續性趨勢

USING THE URBAN INDICATORS SYSTEM TO MEASURE TAIPEI'S SUSTAINABILITY

本研究根據聯合國都市指標系統並參考台北市之特色建構出台北市之都市指標系統，並據此衡量台北市之永續性趨勢。都市指標系統分為關鍵性指標及地方性指標，在7大類49項聯合國關鍵性指標中，台北市有19項可以與其接軌，而依據台北市之地方特色與都市發展趨勢，本研究建議了37項地方性指標及9項特色指標；最後經由永續性原則之考量，本研究篩選了49項指標作為台北市都市指標系統之架構。本研究以1989年到1998年的資料探討台北市都市發展之趨勢，並依此衡量台北市在不同面向中究竟是邁向永續或遠離永績。計算結果以背景資料、地方政府、及住宅三大類較邁向永績，亦即行政部門在市政建設及住宅政策上均有較佳的執行成果，而基礎建設、環境管理指標等項目則只有近四、五年的資料，另外有13項指標因沒有資料而無法進行分析，因此無法呈現完整的永續發展趨勢。而為進行不同城市間的比較與接軌，本文以聯合國都市指標系統作為發展共同知識基礎，並輔以聯合國於1990年所提出人類發展指數，就區域空間及發展程度的觀點，探討台北市在區域上及全球都市發展中所呈現出的都市特質。

This study adopts the UN's Urban Indicators Programme (UIP) as the framework and takes into account Taipei's characteristics to construct Taipei's Urban Indicators System, which is further adopted to measure Taipei's sustainability. There are key indicators and local indicators. Nineteen out of 49 key indicators can be calculated in Taipei City. In addition to the 19 key indicators, this study suggests 37 local indicators and 9 specific indicators. Using the sustainability principles, this study finally selects 49 indicators as Taipei's UIS. A ten-year data set is then collected to measure Taipei's sustainability. Results show that Taipei City performs better in the categories of background information, local government, and housing, while infrastructure and environmental management indicators have only 4 to 5 years of data. No data are available for 13 indicators. At present, no holistic perspective of sustainability trend can be measured for Taipei City. To compare different cities, this paper adopts UN's UIP, and refers to Human Development Index (HDI) to explore Taipei's urban characteristics in view of regional and global urban development.
