The population aged 65 years and above in Hong Kong is projected to rise from 15 per cent in 2014 to 38.4 per cent in 2069. Therefore, the quest for creating age-friendly conditions and the promotion of active ageing has become a priority for the Hong Kong Government and stakeholders in the city. Using a cross-national comparative framework for productive engagement in later life, this article examines the predictors of productive engagement (perceived voluntary engagement) in two districts (the Islands and Tsuen Wan) of Hong Kong – a typical productivist welfare regime in Asia. Data were collected through a social survey to ascertain the perception of an age-friendly city and active ageing in 2016 and 2018 from 1,638 persons aged 60 years and older. The results indicate some differences in the perception of the key determinants in both districts, but the factors associated with productive engagement were consistent, namely social atmosphere, social provisions and the built environment. The findings are discussed within the broader discourse on social gerontology, age-friendly cities and productivist welfare regimes.
