Global value chains and centrality: Mapping key hubs, spokes and the periphery

This paper uses “centrality” metrics to reflect position within global value chains. Central sectors reflect those that are highly connected (both directly and indirectly) and influential within global production networks, whereas peripheral sectors exhibit weak linkages and are less influential. Applying these metrics to OECD ICIO data reveals that there have been profound changes in the structure of GVCs over the period 1995-2011.
