Abstract: We combine the World Input-Output Dataset (WIOD) with OECD data on Analytical Business Enterprise R&D (ANBERD) and build up the network that emerges by mapping the sectoral R&D expenditure that flows in an embodied way among 690 industry-country nodes (23 industries of 30 countries), from 2009 to 2013. Drawing on frontier network analysis techniques, we examine the distribution of the relational properties of the country-industry nodes, identify the most central of them, and detect the clusters that they form. Our analysis reveals that, while the diffusion of embodied R&D is highly pervasive on a global scale, the linkages it creates across sectors tend to be highly asymmetric and polarised. Furthermore, except for transportation and ICT related industries, embodied R&D flows determine communities largely confined within national borders. Despite being based on structural inputoutput relationships, the position and role of country-industry nodes in the global network of embodied R&D knowledge show a certain variability both over time and across network dimensions.
