我國「都市計畫容積移轉辦法」中規定容積接受區須與容積送出區為同一都市計畫地區，以臺北市為例，全區屬同一主要計畫，申請者於房價較低之行政區取得公共設施用地後，將其容積移入房價較高之行政區，產生某些行政區開發量暴增、公共設施服務品質不佳、都市景觀衝擊、都市交通擁擠及缺乏最適容積總量管制等課題。 本研究以都市容受力理論觀點，提出最適容積總量的評估機制，利用ArcGIS系統了解臺北市各行政區及街廓發展現況，掌握其各種屬性，作為建立分類指標參考，再藉由因子分析、集群分析等研究方法，進行都市容受力評估以及街廓條件分類。 最後，根據實證研究結果，建議臺北市容積移轉制度須檢討各行政區容積發展總量、評估都市發展容受力、考量其他容積管制政策、調整容積移轉範圍、規定各行政區接受基地街廓分類與移入容積上限及擬定容積移轉接受基地相關規範，以作為容積移轉政策之執行參考。 / As stipulated in the Regulations of Urban Building Capacity Transfer, the recipient and donor of transferred building capacity need to be located in the same urban planned district. Take Taipei City for example, it is covered in the same urban planned area. As developers acquire public facilities lands in administrative areas of low land prices, and then transfer the building capacity got from the former to the administrative areas of high land prices. The behavior of developers mentioned above, will trigger a rapid increase of development capacity in certain administrative areas, impact the service quality of public facilities, urban landscape, traffic condition, and optimal control of building capacity. Based on the theory of urban carrying capacity, the study proposes an optimal building capacity assessment mechanism. ArcGIS is used to trace the current development and understand the various features of the administrative areas and street blocks in Taipei City so as to help establish relevant classification indicators. Factor and cluster analyses are then conducted to facilitate urban carrying capacity assessment and classification of street blocks. Finally, on the basis of the empirical results , this study offers the following suggestions for achieving more effective implementation of the urban building capacity transfer system in Taipei City: reviewing the total building capacity in every administrative areas, assessing urban carrying capacity, exploring other policies for building capacity control, adjusting the scope of building capacity transfer, classifying the street blocks of the recipient sites in every administrative areas, limiting the volume of transferred building capacity, and drafting regulations for recipient sites of transferred building capacity.
