This paper employs a comparative analysis to investigate the state-led use of industrial heritage in major Chinese mega-events, delving into the three cases of the Guangzhou Asian Games, the Shanghai Expo, and the Beijing Winter Olympics. Examining the evolving practices led by Chinese governments reveals unique pathways for industrial heritage and showcases its diverse roles in economic development and societal transformation. The three cases illustrate the nuanced dynamics between market forces and state interventions, emphasising the importance of strategic planning and long-term considerations in mega-event-induced heritage practices. Mega-events serve as catalysts for urban regeneration, allowing governments to allocate substantial resources to conserve and repurpose industrial heritage. However, the current paper contends that the sustained benefits of industrial heritage hinge on thoughtful planning for long-term economic and social sustainability, emphasising the need to constrain a focus on shortterm gains through land revenue. These reflections contribute to a nuanced understanding of the intricate interplay between heritage preservation, economic development, and sustainable urban planning in the context of China's mega-events.
