This is the regional extension to EXIOBASE 3 called EXIOBASE 3rx where the number of regions have been expanded from 49 to 214. In its current form it has six land use extensions processed. Adding other extensions is a work in progress. The database is in .mat format (MATLAB). Database features: 214 countries 200 products 163 industries 6 aggregated land use extensions Basic pricing Monetary unit: Million Euros (current prices) Arrays in IO structure: S Stressor matrix per monetary unit A The coefficient matrix (inputs required per unit of output) V Value added matrix Y Final demand matrix x Vector of total output TC Trade cube (product x exporter x importer) F Total stressor matrix F_hh Total household stressor matrix pop Population per country gdp GDP per country VY Value added final demand For information about indexing see the meta file. All countries are in ISO3 format - full country names and corresponding ISO3 codes are found in the gdp and pop arrays. Important note: Y and A only contains domestic data to reduce the array sizes. This means that the off-diagonal arrays corresponding to the trade are not included (you can see this by typing the command spy(IO.A) after loading the database in MATLAB). The implication of this is that the conventional MRIO calculations are not applicable. Rather we recommend to use the emissions embodied in bilateral trade (EEBT) approach. This approach works with the current version of EXIOBASE 3rx, and requires using the trade cube (TC) for calculating the traded components of land use. Several arrays are saved in the sparse format of MATLAB to reduce file size and might require conversion to the full format for some calculations. Note that calculations can be computationally heavy and might require the use of super computers. For more information about EXIOBASE in general, see the official website: https://www.exiobase.eu/
