The rising need for complex and specialized knowledge and technological interaction at both national and international level has resulted – paradoxically – in both geographical concentration and dispersion of innova tion creation, as highlighted in Chapter 1. On the one hand, organizations have sought to locate innovation activities and interactions wherever high quality and lower costs are available. On the other, market forces, economies of scale and the need for more faceto face communication and multidisciplinary interaction, because of the complexity of the interactions, have pulled in the direction of geographical proximity. Global innovation networks have been a key centrifugal force in the geographical distribution of knowledge creation activities. Knowledgeseeking FDI does not target whole countries, but specific locations within them. Most international collaborations, investments or movements of skilled workers occur between specific knowledgeproduction centers. But global innova tion networks do not merely span frontiers, they link specific locations within countries and reinforce the national prominence of these locations; within national borders, interregional innovation subnetworks coexist with global ones. In view of these considerations, it is crucial to under stand empirically the geographical concentration and spread of the world’s scientific and technical knowl edge production and interactions. This requires fine grained mapping of innovation activities within national borders and how these contribute to the worldwide dispersion of knowledge exchanges. In particular, it is important to examine whether the growth of national 31 World Intellectual Property Report 2019 knowledgeproduction centers or hubs results in an overall increase in international collaboration and investment or whether they simply suckin innovative Box 2.1 Patent and scientific publication activities to the detriment of other areas in the country geocoded data or beyond in a zerosum game.
