Exploring the composition features of commercial gentrification - a case study of Taipei City

Abstract

The phenomenon of commercial gentrification, marked by transformations in commercial spaces and retail patterns, is increasingly evident globally, significantly altering consumption spaces to cater to new residents and impacting main shopping areas. This study examines commercial gentrification in Taipei City, focusing on identifying affected areas and analyzing their environmental characteristics. Using secondary dissemination areas as spatial units, the research constructs quantifiable indicators to map the occurrence of commercial gentrification. Principal component analysis (PCA) is employed to explore the environmental factors correlated with this process. Taipei City's historical and economic evolution, characterized by significant infrastructure developments and commercial transformations, provides the context for this study. The threshold strategy revealed patterns of commercial gentrification within the Da'an, Zhongzheng, and Songshan districts, with Da'an displaying the most significant changes. The weighted results suggest that areas experiencing commercial gentrification showcase a high degree of diversity, a lower presence of vulnerable populations, and superior public transportation and amenities. This study aims to provide insights into the spatial dynamics and environmental impacts of commercial gentrification, offering a comprehensive understanding of its progression in Taipei City.
