Rapid outward expansion of urban land in many of China's cities has resulted in the production of spatially diverse suburban areas, including newly developed residential complexes and the incorporation of existing neighbourhoods into the urban fabric. The concept of 'community well-being' provides a useful framework to examine the relationship between the well-being of individuals and the physical environment and spatial conditions in which they live. While the study of subjective well-being and its determinants has been rapidly established in China, most research tends to be at the city and provincial level. By adopting a spatial planning perspective, this paper aims to make an original contribution by examining community well-being in Beijing's suburban neighbourhoods, which formed via the rapid suburbanisation process underway since the 1990s. The underlying dynamics and spatial variations of community well-being are assessed by subjective and objective measures and taking both personal attributes and neighbourhood environmental factors into account to draw out policy implications for sustainable urban development.
