This article aims to analyse the European pig sector and its transformations (e.g. vertical integration and phase specialization).In particular, we will both explore the specialization and territorial concentration of pig production, and the significant changes which have taken place in the trade among European Union countries. Using the network analysis (betweenness centrality, node strength and community detection) applied to Eurostat and fao datasets on production and trade in the period 2000-2016, we will show the emergence of national players and international connections that lead to a larger continental market. Finally, this evidence will be used in the discussion and conclusion to raise wider concerning the working of agrifoodvalue chains, in terms of social, economic and environmental sustainability, as well as regulation. This calls for more interdisciplinary analyses of value chains.
