Whilst innovative performance has been viewed as a function of both a firm's network structure (Ahuja, 2000, Salman and Saives, 2005) and it's location (Powell et al., 2002), little research to date has sought to integrate these perspectives (Oerlemans and Meeus, 2005). read more »
A Stochastic Theory of Geographic Concentration and the Empirical Evidence in Germany
Submitted by Bruno Chaves on 30 March, 2007 - 10:37.
