This study investigates the impact of urban renewal projects on the sense of community among residents and visitors in Hong Kong, with a focus on the psychological and social implications of displacement. By analyzing six significant urban renewal projects—Kwun Tong Town Centre, Central Market, Wan Chai Blue House, Tai Kwun, The Mills, and PMQ—this research explores how these transformations affect community cohesion, cultural preservation, and social identity. The analysis leverages social media portrayals, particularly Instagram posts, to capture real-time community sentiments and emotional responses to the changes brought about by these projects. Findings indicate that urban renewal projects that prioritize community involvement, heritage conservation, and cultural programming are more successful in fostering positive community outcomes. Projects like Wan Chai Blue House and Tai Kwun, which adopted a community-centric approach, preserved social cohesion and reinforced community identity. In contrast, large-scale redevelopments such as Kwun Tong Town Centre, driven primarily by commercial interests, often led to feelings of displacement and loss among residents. The study underscores the importance of balancing modernization with the preservation of community values and highlights the critical role of stakeholder engagement in achieving sustainable urban renewal. Based on the findings, the study recommends that future urban renewal projects emphasize community participation from the outset, integrate cultural and social programming, and adopt a holistic approach that considers the social, economic, and cultural dimensions of redevelopment. By doing so, urban renewal efforts can enhance community cohesion and ensure that redevelopment projects contribute positively to the urban fabric of Hong Kong and other cities facing similar challenges.
