Expo 2010 Shanghai China: a signature chapter of the Huangpu Riverfronts Trilogy

Purpose - Over decades, mega-events have enjoyed increasing global popularity as catalysts of significant urban renewal both on and beyond the event grounds. Nevertheless, although some mega-events are exemplary in their transformation of some places, post-event failure of others highlight a lack of long-range planning. Yet, such a paradoxical relationship between spectacularity and sustainability has, so far, received little in-depth analysis. Building upon the Yin-Yang theory, the purpose of this paper is to identify the Triple-C gap and argues that planning for mega-event led renewals (MELRs) is an issue of dualism rather than dichotomy. Design/methodology/approach - This paper adopts the multiple-case study approach. Two methodological steps are taken to seek a greater understanding of the issue at global and local scales. One is a review of eight mega-event cases in the West to identify post-event sustainability challenges. The other explores these challenges through an examination of the Expo 2010 development as a chapter of the Huangpu Riverfronts Renewal in Shanghai China. Findings - The eight historical cases and Expo 2010 unanimously challenge the dichotomy between event staging and post-event sustainability. It is therefore high time for future client organizations to rethink how to find a convergence. Practical implications - With lessons drawn, the article concludes that planning an MELR should be pre-post oriented and serve as a catalyst for broader-scale improvements. Originality/value - This pioneering study constitutes a much-needed reference for future mega-event hosts to rethink their commitment to MELDs, which will hopefully spark more interdisciplinary interest.
