Abstract

Global value chains (GVCs) require new methods for evaluating interconnections among countries, which can no longer be accurately appraised by standard bilateral gross trade flows. This paper uses tools of network analysis to examine the evolution of value-added trade from 1995 to 2011. GVCs are very centralised and asymmetric networks, with a few large economies acting as hubs, which exposes them to the propagation of idiosyncratic shocks. As GVCs expanded, the networks of foreign value added in exports became denser, more complex and intensively connected. The regional dimension of GVCs is still dominant but is progressively giving place to a more global network. Networks of foreign value added in goods exports outpace those of services exports. However, foreign inputs of services are important for exports of both goods and services. There is a striking rise of China as a supplier of value added, while Germany and the United States maintain a central role in GVCs over the whole period.
