Research Networks and Inventors' Mobility as Drivers of Innovation: Evidence from Europe

M<sc>iguélez</sc> E. and M<sc>oreno</sc> R. Research networks and inventors' mobility as drivers of innovation: evidence from Europe, <italic>Regional Studies</italic>. This paper investigates the importance of the labour mobility of inventors, as well as the scale, extent and density of their collaborative research networks, for regional innovation outcomes. To do so, a knowledge production function framework at the regional level is used. The empirical approach presented takes full account of spatial interactions by estimating a spatial lag model, together, where necessary, with a spatial error model. In addition, standard errors are calculated using spatial heteroskedasticity and autocorrelation consistent (SHAC) techniques. The results suggest the existence of a robust positive correlation between intra-regional labour mobility and regional innovation, whilst the relationship with networks is less clear.
