World trade and production are increasingly structured around “global value chains” (GVCs). The last few years have witnessed a growing number of case studies describing at the product level how production is internationally fragmented, but there is little evidence at the aggregate level on the prevalence of GVCs. The main objective of this paper is to provide for more and better evidence allowing the examination of countries’ position within international production networks. We propose a number of indicators that give a more accurate picture of the integration and position of countries in GVCs, as well as a more detailed assessment of the value chain in six broad industries: agriculture and food products, chemicals, electronics, motor vehicles, business services and financial services.
Keywords: global value chains, fragmentation of production, production stages, vertical specialization, backward linkages, forward linkages, input-output, supply chains, trade in intermediate inputs.
