Résumé : Production processes have become increasingly fragmented over the last three decades, leading to the emergence of so-called global value chains (GVCs). This fragmentation particularly affects small open economies such as Belgium. For instance, Dhyne and Duprez (2015) showed that, between 2002 and 2012, 82 percent of commercial firms in Belgium produced goods and services that were directly or indirectly exported. In this context, this article surveys the literature on the effects of firms' participation in GVCs, especially from the perspective of the position they occupy in these chains. These effects are analyzed in terms of productivity and rent-sharing between wages and profits. We focus mainly on studies carried out at the firm level, paying particular attention to the empirical results relating to the Belgian economy.
