| Abstract: | This paper examines the complex mix of technological innovation, economics, social networks, ideologies and interest groups that spur the diffusion of certain new mega-project approaches at punctuated moments in time. Situating mega-projects within a context of long-range economic cycles and competitive urban entrepreneurialism on a global scale, cyclical patterns of innovation are identified, where successful early trendsetter mega-projects have stimulated interest groups to promote similar projects in their own cities. The paper concludes that the global diffusion of mega-project innovations are driven by the political and policy lure of achieving major tangible benefits, as well as the potential to convey a powerful set of symbolic messages. |
