We investigate how variety affects the innovation output of a region. Borrowing arguments from theories of recombinant … innovation, we expect that related variety will enhance innovation as related technologies are more easily recombined into a new … technology. However, we also expect that unrelated variety enhances technological breakthroughs, since radical innovation often …

consistent approach to integrate innovation, space and economic growth into a coherent theoretical framework A potential reason … for this is that the spatial dimension of knowledge production is still only partly understood in the empirical literature …. To shed some additional light on the spatial dimension of innovation we present results of a first-cut analysis building …
