After classifying them with a communication research method-the content analysis, a data bank for SPSS is set up, and a mathematic model called the Integrated Impact Index of Expo '99 Kunming is constituted. With the model, the spatial distribution of the total integrated impacts of Expo '99 Kunming on the regions or cities with different regional scales is analysed quantitatively. The conclusions are: 1) the Expo '99 Kunming made obvious integrated impacts on the regions or cities of every scale, especially in the venue city and the region-Kunming City and Yunnan Province; 2) it had corresponding impacts on other provinces; 3) the spatial distribution of Integrated Impact Index had a disaggregation with both plane extension and spotted decentralization; and 4) there was a distance decay law in all three scales of regions (Kunming City, Yunnan Province and the whole China), which incarnated the spatial extension law of the integrated impact of a special mega-event.展开更多

It argues that spatial-related transformation is central to mega-event approach to glurbanization yet the soft power building is uncertain. It implies that the domestic impacts of mega- events are likely to be more profound than their global influences. This corresponds to the capitalist transformation from Fordist-Keynesianism to neoliberalism, in which mega-events such as Olympic Games and World Exposition have increasingly been incorporated into urban development plan to boost urban agenda. Although the profile of world fairs is reduced and does not have the international impacts that they used to have, Shanghai Expo 2010, the first Expo ever held in a developing country, is pinned hope on as the “Turn to Save the World Expo” and is unusually ambitious to bring opportunities in urban transformation. With a well-developed framework of glurbanization entailed by entrepreneurial city, this research enriches glurbanization theory by a thorough examination of Shanghai Expo. It finds that Expo-led landscape reconfiguration, spatial restructuring, and new sources provision effectively transformed Shanghai, propelling glurbanization in diminutive spatial scale. Yet, it remains powerless to impress the world as the voice of domestic propaganda is limited in the Western mainstream media. In all, the Expo case well exemplifies the power of mega-event approach to advancing local agenda, especially in spatial transformation per se, as well as its constraints in (re)shaping a global discourse.展开更多

The recognition and support of local community residents are one of the most important factors in the success of mega-events. The study of the impact of mega-events on community residents is crucial to the success of the events. Taking the thesis Comparative Study on Residents' Perceptions to the Followup Impacts of the 2008 Olympics for example, this paper, from the perspective of the impact of megaevents on community residents, discussed the contribution of this thesis to Beijing and Zhangjiakou, the host city and co-host city for the 2022 Winter Olympics respectively, and the countermeasures that should be taken by event organizers.展开更多

Sport mega-events, such as America＇s Cup, have been recognized as a strong component of tourism, and are becoming an integral and major part of tourism development and marketing strategies. As a catalyst for change, sport mega-events can accelerate the host city economic, political, and social development. This paper focuses on the case of the 34th America＇s Cup for Naples. In order to evaluate the benefits of this event on the city, the authors first propose a general framework of main benefits that sport mega-events may bring to host cities, and subsequently, the authors applied this framework to the Naples case.展开更多

Despite its unfailing popularity and controversial nature, many initiators seem to equate MEF development with signature architecture, resulting in a persistent issue of underuse among MEFs in the post-event era. Although research findings indicate that the early stages hold the key to the future of MEFs, insufficient research on this crucial matter has been done to provide useful analyses as to how to achieve this. To rectify this, this paper presents a case study of China Pavilion （CP） as the most spotlighted MEF initiated by Expo 2010 Shanghai China. Through participant observation, archival records, and documentation, the case of CP was extensively explored to learn how the client organization has addressed the issues of form, function, and future positioning at the early stages. By linking the pre-Expo conceptualization with its post-Expo performance, the case brings a renewed attention to the early stages of MEF development. Although it is a single-case study, this research yields results that indicate the possibility of having beneficial spillover impact on broader-scale urban renewal by balancing an MEF＇s dual mandate.展开更多
