本研究以新北市三重區為例，借鑒縉紳化概念，聚焦於地方意象、交通、住宅、綠地及消費地景，探討地域轉型。研究發現:三重的轉變接近西方以房地產開發作為振興策略的第三波縉紳化，但國家角色更鮮明。雖然部分窳陋地區和農地轉變為中上階級住宅，但階級替換效果不明顯，同時呈現都市擴張與舊城區再開發的特徵。舊工業遷移、新零售服務業進駐，展現了都市生活支持系統的再結構，但呈現新舊交錯的異質地景。簡言之，三重的轉型可視為混合土地使用與非正式部門下的舊便利城市的升級版，尤其水岸遊憩化具有淨化效果，呈現現代化的文明進步都市意象。

This article applies the concept of gentrification to examine urban transformation in the Sanchong District of New Taipei City, focusing on changes in local image, transportation system, green lands, new housing developments, and landscape of consumption. The authors discovered that the transformation of Sanchong was similar to third-wave gentrification in Western societies, which adopted housing development as a regeneration strategy. However, the role of the state was more significant in gentrification in Taiwan. While the high price of new housing developments excluded lower-class residents, most construction sites had been farmlands or factories, implying limited displacement of residents. Sanchong's transformation exhibited the features of both urban expansion and gentrification. The moving out or closing down of old factories and the new retailing landscape filled with chain-stores showed a restructuring of the support system for urban life that resulted in a heterogeneous landscape. In brief, the transformation of Sanchong may be viewed as an upgrading of the old convenient city,which featured mixed-use urban texture and informal activities, and as an example of a modernized and civilized urban image, especially in the purification effect of the riverside recreational area.
