Abstract
ABSTRACTThis paper investigates the role of inventor networks in regional inventive capacity in Brazil for 558 regions in the period 2000–11. Based on the knowledge-production function (KPF), it focuses on four network measurements: intra- and interregional collaborative inventor links, density of the network, and international collaboration among Brazilian and foreign inventors. The main results show that intra-regional inventive collaborations exert a positive impact, while denser networks negatively influence regional inventive productivity. Interregional collaborative links have a ‘U’-shape relationship with inventive productivity only for South and Southeast. Inventions in the North, Northeast and Centre–West rely on international collaborative links.
