| 摘要: | 台灣地區的都市，歷經數十年來急速的擴張，部分已發展地區已呈現老化衰退的現象。都市須透過更新及再結構來提升城市競爭力。但政府之資源有限，且各地區的需求不同，又因都市更新事業的第一步即為更新單元的劃定，該優先劃定何地區的實施都市更新事業為一個複雜且多面向的問題。選擇都市更新優先推動地區實為近年地方政府施政之重要課題，如何建立評估及選擇確切適合的都市更新優先地區之相關評估準則，做為地方政府之重要的決策參考，為本研究的目的。
地方政府資源有限，該優先劃定何地區的實施都市更新事業為一個複雜且多面向的問題。根據「緊縮成市理論」，現階段都市的成長應以質發展為的主而非以量的成長為優先。以台北市為例，1998/11/11公佈「劃定台北市都市更新地區案」優先劃定更新地區共535.98公頃(281處)，至2018/06/30僅完成6.18%。都市更新的推動成效不彰。因此台北市政府於2018/12/10公布了「劃定臺北市都市更新地區暨擬定都市更新計畫案」參考了近20年的推動經驗台北市政府改變了公劃更新地區的實施戰略。首要的戰略即為劃定地區的「範圍檢討」，第一要項即為檢視公劃地區範圍合理性。由此可見，都市更新優先推動地區的選擇是一非常重要的評估及決策的課題。本研究運用階層構造分析法(Interpretive Structural Modeling)及層級分析法(Analytic Hierarchy Process，AHP) 於建構都市更新優先劃定評估準則及九尺度評估法建立相關評估準則及排序與權重。
本研究從政治、經濟、社會、環境等四個準則，並建立相關準則之評估因子。建構都市更新優先推動相關評估準則及評估因子之層級，並建立相關評估準則及評估因子之局部權重及整體權重與排序。排名: 政治1，經濟2，社會4，環境3。增進公眾利益1，TOD模式5，重塑都市機能(都市再生) 2，提升開發效益3，創新經濟模式7，促進經濟發展11，照顧弱勢群族6，改善社區生活10，保存在地文化9，土地合理使用4，促進都市防災8，增進環境永續12。
After decades of rapid expansion, some developed areas in Taiwan have been aging and declining. Cities need to upgrade and restructure to improve their competitiveness. However, due to the limited resources of the government and the different needs of different regions, and because the first step of urban renewal is the designation of renewal units, it is a complex and multi-faceted problem to prioritize which areas to implement urban renewal. In recent years, it has been an important issue for local governments to choose urban renewal as their priority. The purpose of this study is to establish evaluation criteria for the evaluation and selection of urban renewal priority areas, as an important decision-making reference for local governments.
Given the limited resources of local government, it is a complex and multi-faceted problem to prioritize the implementation of urban renewal in the designated areas. According to the “Compact City Theory”, the growth of cities at present should be based on the quality rather than the quantity. Taking Taipei city as an example, on November 11, 1998, the “Zoning Plan for Urban Renewal Area of Taipei City” was announced to prioritize the designation of 535.98 hectares (281 plots) of renewal areas, and only 6.18% of them were completed by June 30, 2018. The promotion effect of urban renewal is not significant. Therefore, the Taipei municipal government released the “Zoning Plan for Urban Renewal Area of Taipei City and Plan for Urban Renewal” on December 10, 2018, referring to the recent 20 years' experience in promoting urban renewal. The Taipei city government has changed its strategy for implementing public renewal. The primary strategy is to conduct a “scope review” of the delineation of the district. It can be seen that the choice of priority areas for urban renewal is a very important issue for evaluation and decision making. In this study, the Interpretive Structural Modeling (ISM) and Analytic Hierarchy Process (AHP) were used to establish the evaluation criteria, ranking and weight of urban renewal based on the prioritization evaluation criteria of urban renewal and the nine-scale evaluation method.
In this study, the evaluation factors of four criteria were established from the perspectives of politics, economy, society and environment. Construct the hierarchy of relevant evaluation criteria and factors, and establish the local weight and overall weight and ranking of relevant evaluation criteria and factors. Rank: politics 1, economy 2, society 4, environment 3. Promote public interest 1, TOD model 5, reshape urban function (urban regeneration) 2, improve development efficiency 3, innovate economic model 7, promote economic development 11, take care of the disadvantaged groups 6, improve community life 10, preserve local culture 9, rational use of land 4, promote urban disaster prevention 8, improve environmental sustainability 12. |
