For comparisons between European Union countries, refer to Eurostat indicators.

GVC 2020 is the third survey on global value chains.

The 2011 survey interviewed legal units, so the collection unit and statistical unit are not comparable with GVC 2020.

The 2016 GVC-SME survey interviewed enterprises as defined by the 2008 LME but only covers the SME field. The data are comparable only on this sub-field.
