Supply and use tables are matrices by product and industry describing production processes and products' transactions in great detail. Industries are classified according to NACE and products according to CPA. These classifications are fully aligned to each other: at each level of aggregation, the CPA shows the principal products of the industries according to the NACE.
These tables record:
- the structure of the costs of production and the value added generated in the production process;
- the flows of goods and services produced within the national economy;
- the flows of goods and services with the Rest of the World.
The supply table shows the supply of goods and services by product and by type of supplier, supply by domestic industries and imports are distinguished. The use table shows the use of goods and services by product and by type of use, i.e. as intermediate consumption (in the production process by industry), final consumption, gross capital formation or exports. Furthermore, the table shows the components of gross value added, i.e. compensation of employees, other taxes less subsidies on production, net mixed income, net operating surplus and consumption of fixed capital.
Supply and use tables are interlinked by two types of identities:
- the identity by industry, i.e. output by industry must equal input by industry or
in other words, for each industry:
output = intermediate consumption + value added
- the identity by product, i.e. total supply by product must equal total use by product or
in other words for each product:
output + imports = intermediate consumption + final consumption + gross capital formation + exports
Supply and use tables contain all the flows in the goods and services account, the production account and the generation of income account.
A symmetric input-output table is a product-by-product or industry-by-industry matrix describing the domestic production processes and the products´ transactions in great detail. A symmetric input-output table rearranges both supply and use in a single table with identical classification of products (or industries respectfully) employed for both rows and columns.
The methodology of consolidating national tables into a consolidated European table is described in a technical documentation (see right panel).
