“…Our study has a more important implication for the field of research on IDs: given the changes that have taken place, to understand the competitive dynamics affecting a given ID, wherever it may be located, we need to place the analysis within the framework of the global value chain of which the district is a part. This analytical stance has often been taken to explain the upgrading processes seen in several clusters in developing countries, and Latin America in particular (Bair & Gereffi, 2001;Giuliani et al, 2005;Humphrey & Schmitz, 2002;Pérez Sáinz, 2003). The global value chain perspective has only been used quite recently to analyse the IDs of Europe, confirming its utility when it comes to understanding the competitive position of IDs and how it has changed over time (Amighini & Rabellotti, 2006;Belussi & Samarra, 2010;De Marchi et al, forthcoming;Hervás-Oliver et al, 2008).…”
