The state frequently makes use of the transit-oriented development initiative to promote economic growth and revitalization. The Mass Transit Railway Corporation in Hong Kong uses the "Rail plus property" development model to make public transportation networks selfsufficient financially and promote sustainable urban expansion. Due to increased residential construction and the alteration of retail spaces and social services, however, it also serves as a catalyst for neighbourhood change in nearby neighbourhoods, resulting in transit-induced gentrification or parallel processes like suburbanization and professionalisation. Studies on gentrification brought on by TOD, particularly at the neighbourhood level and its relationship to social inclusion, are, nonetheless, underdeveloped in the Asian context. This raises the question the extent to which state-led new transit investment in Hong Kong accounts for neighbourhood changes (gentrification, suburbanisation and professionalisation) and whether such changes create a more socially inclusive neighbourhood in Hong Kong. To understand the changes in the sociodemographic characteristics, perceived neighbourhood change, and social inclusion of residents, qualitative (primary and secondary data) and qualitative (semistructured interviews) methods were used based on the Tseung Kwan O Town Centre case study, which has undergone significant changes over the past 20 years after the opening of the MTR station in 2002. The results from the housing price for owner occupation and census data indicated that there may be some overlap between the three neighbourhood transformation processes in the neighbourhood. Longterm inhabitants have noted the suburbanization of families and the commercial gentrification of stores, although due to the presence of public housing estates prior to the station's construction, there has been limited residential gentrification. Although accessibility and the quality of living environment have improved, however, long-term residents still struggle as the shops are less affordable.
