Measuring global value chain participation in UK regions

This paper outlines alternative approaches to constructing subnational Supply and Use Tables (SUTs) for the United Kingdom, combining microdata with publicly available national and regional statistics. It introduces an experimental framework to analyse how UK regions are directly and indirectly integrated into the global economy. Comprehensive regional SUTs and Input-Output Tables (IOTs) have so far been unavailable for the United Kingdom, limiting the analysis of regional economic linkages and global integration. Developing such tables is important for both policy and methodological purposes, as they support the assessment of regional production structures and inform targeted policy design. The resulting dataset covers 12 UK regions and an additional “extra-regio” aggregate, disaggregated into 50 industries and products over the period 2017–21. Estimates are derived by combining different official UK microdata, integrating subnational value added and consumption data with firm- and household-level information. The derived tables are incorporated into the OECD’s Inter-Country Input-Output (ICIO) framework, enabling the first set of subnational Trade in Value Added (TiVA) indicators for the 12 UK TL2 regions (equivalent to ITL1 regions).
