Mega-event and urban sustainable development

Purpose - The purpose of this paper is to identify the impact indicators of the 2010 Taipei International Flora Exposition from the perspective of residents and to investigate the effects of these impacts on the urban sustainability through the perceptions of Taipei residents after the exposition. Design/methodology/approach - The authors conducted a literature review and consulted experts to identify the impact indicators of the exposition. This process resulted in 17 indicators of economic impact, 12 indicators of environmental impact, and 13 indicators of social impact, and the authors developed a 12-dimension/42-indicator mega-event impact measurement scale. Using a survey of 1,628 host residents after the exposition, the authors performed regression analysis to investigate the effects of these impacts on the urban sustainability. Findings - The results indicated that economic, environmental, and social impacts exerted significant positive effects on urban sustainability. All positive dimensions of economic, environmental, and social impact exerted significant positive effects on urban sustainability, and all negative dimensions exerted nonsignificant effects on urban sustainability. Originality/value - This study identified the impact indicators of the 2010 Taipei International Flora Exposition and investigated the effects of these impacts on the urban sustainability. The findings of this study indicated that economic, environmental, and social impacts of the exposition exerted significant positive effects on urban sustainability.
