| 摘要: | 都市更新的主要目的是以促進都市土地有計畫之再開發利用、復甦都市機能、改善居住環境與景觀以及增進公共利益。然而隨著臺北市都市更新之容積獎勵、稅賦減免以及融資優惠等獎勵制度下，使得都市更新地區多集中於具有市場價值的市中心，而非真正已有都市窳陋的邊緣地區。此外，都市更新後的地區使得當地居住成本提升，無法負擔的居民只能搬離，取而代之的為可負擔更新後房價的中產階級，進而導致仕紳化 (Gentrification) 現象的產生。
為釐清都市更新地區是否集中於具有市場價值的市中心以及都市更新的實施是否即是造成都市仕紳化的原因，本研究首先透過2012至2020年之實價登錄資料分析房價較高之地區是否更容易形成都更地區。其次，以2007年為基期，以臺北市2012至2020年456里為研究範圍，利用人口遷移比例、大學以上人口比例、薪資所得、財產交易所得及連鎖餐飲等變化建立仕紳化指標，再利用多期差異中之差異法，分析影響仕紳化主要因素，期望就由量化分析結果可納入未來都市更新政策考量之依據。
根據研究結果都市更新單元劃定前之高房價地區確實對都市更新單元的劃定有正向之影響關係，且距離住宅交易案之標的越近效果越顯著，顯示出都市更新單元的劃定明顯受房市的影響。而仕紳化現象於都市更新單元劃定後一年開始直至都市更新單元劃定後三年皆有顯著之正面影響，但此正向影響會隨著都市更新的劃定時間經過而減弱。本研究證明地方政府為推動都市更新之政策所造成的生產面對臺北市的仕紳化過程的影響相較於消費面更來的重要，不同於大部分西方國家仕紳化來自消費面影響。
The main purpose of urban renewal is to promote the planned redevelopment & utilization of urban l&, revive urban functions, improve the living environment & l&scape, & enhance public interests. However, with the incentive system of urban renewal in Taipei City, such as volume incentives, tax reductions & exemptions, & financing incentives, urban renewal areas are mostly concentrated in the city center with market value, rather than the fringe areas where there are already poor urban areas. In addition, the urban renewal area has increased the cost of local living, & residents who cannot afford it can only move out & be replaced by the middle class who can afford the updated house price, which in turn leads to the phenomenon of gentrification .
In order to clarify whether urban renewal areas are concentrated in the city center with market value & whether the implementation of urban renewal is the cause of urban gentrification, this study first analyzes whether areas with higher housing prices are based on real price registration data from 2012 to 2020. It is easier to form all more regions. Secondly, taking 2007 as the base period & taking the 456 miles of Taipei City from 2012 to 2020 as the research scope, the gentrification indicators were established by using the changes in the proportion of population migration, the proportion of the population above university level, salary income, income from property transactions, & chain restaurants, etc., & then Using the multi-period doubling method to analyze the main factors affecting gentrification, it is expected that the quantitative analysis results can be incorporated into the basis for future urban renewal policy considerations. |
