Determinants of Network Evolution
暂无分享,去创建一个
Evolutionary thinking in a network context emerged only recently on the research agenda. For instance, Gluckler (2007) addresses the question how tie selection constitutes an evolutionary process in networks. More precisely, he argues that network tie selection processes cause retention and variation within network structures. Hite (2008) presents an evolutionary multi-dimensional model of network change that explicitly considers micro level network change processes. Witt (2006) argues that selection processes are, in line with Neo-Schumpeterian approaches, constitutive for evolutionary economics. Studies on the evolution of network structures have typically focused on external factors (e.g. competitive pressure) as drivers for change processes.
