The transformation of Beijing as a dual Olympic city: growth, post-growth, and the reimagining of the capital.

This article employs an Olympic urbanism perspective on the transformation of Beijing's planning and development. For Beijing, holding the Olympic Games was not just about staging the city – and the nation – to the world as commonly understood. It was also about transforming the city through megaprojectification – the use of megaprojects like the Olympic Games to boost urban growth. The 2008 Summer Olympics played a critical role in growing Beijing in terms of the economy, population, fixed assets investment, infrastructure provision, and real estate development. Rapid but ill-planned growth within a decade exacerbated many pre-existing problems of the megacity. In the post-Olympic years, big city syndrome became Beijing's calling card: pollution, congestion, unliveability, and unsustainability. Since then, a post-growth discourse has been emerging, reimagining the capital's future in the context of balanced, coordinated development of the Beijing–Tianjin–Hebei region. These include the construction of a new city Xiong'an to decentralize Beijing. This post-growth discourse that influenced the 2022 Winter Olympics was a contrast to the growth discourse that had underpinned the 2008 Summer Olympics. Beijing presents an unusual case of holding two Olympics within a short timeframe but under two contrasting urbanisms. [ABSTRACT FROM AUTHOR]
