Global value chains

Estimating trade in terms of value added provides a new perspective on trade patterns. The OECD-WTO Trade in Value Added (TiVA) database provides data on the origin of the value added in gross exports. This can be used to outline trade flows taking place within global value chains (GVCs). TiVA data is based on the International Standard Industrial Classification (ISIC Rev.3) that covers all sectors of the economy, including primary products, manufactured goods and services.
