Correction: April 12, 2006 - Please note that there have been some changes made to the Japanese tables for 1996 and 1997 to correct for errors that were introduced in the process of preparing files for electronic dissemination. The latest tables correct for these errors. Although the changes are, typically, not significant, they have no impact for example on the total (domestic+import) tables, we apologise for any inconvenience that may have been caused.
Input-Output tables describe the sales and purchases relationships between producers and consumers within an economy. They can be produced by illustrating flows between the sales and purchases (final and intermediate) of industry outputs or by illustrating the sales and purchases (final and intermediate) of product outputs. The OECD Input-Output database is presented on the former basis, reflecting in part the collection mechanisms for many other data sources such as research and development data, employment statistics, pollution data, energy consumption, which are in the main collected by establishments, and so industry.
This set of OECD Input-Output tables consists of matrices of inter-industrial transaction flows of goods and services (domestically produced and imported) in current prices, for eighteen OECD countries (Australia, Canada, Czech Republic, Denmark, Finland, France, Germany, Greece, Hungary, Italy, Japan, Korea, Netherlands, Norway, Poland, Spain, United Kingdom and United States) and two non-member countries (Brazil and China) covering one or more years around the mid-1990s. The tables are based on ISIC Revision 3 industrial classifications and are available in zipped Excel format. Further information for each country is available in the Country Notes.
The database is a very useful empirical tool for economic research and structural analysis at international level. It highlights inter-industrial relationships and covers not only manufacturing but also services. When used in conjunction with other OECD databases on industrial structures, such as STAN Industry Database, Business Research & Development Expenditures by Industry (ANBERD) and the Bilateral Trade Database (BTD), it provides a tool for consistent economic analysis of growth, structural change, productivity, competitiveness and employment at both the sectoral and macroeconomic levels. Increasingly, input-output tables are also being used in environmental analysis; for example, to measure direct and indirect pollutants produced by industrial sectors within an economy and, importantly, 'leakages' between economies (see documents on Carbon Emissions and on Productivity Growth in Services Industries).
The database also contains tables for earlier years, in constant and current prices, covering ten OECD countries (Australia, Canada, Denmark, France, Germany, Italy, Japan, Netherlands, United Kingdom and United States) and (broadly) five year points from the early seventies through to the early nineties. These were produced using an earlier system of national accounts (SNA68) and industrial classification system (ISIC Revision 2). The industry breakdown in the 2002 edition tables is more detailed, reflecting the increased importance of the service sector. More information on the old input-output database is available in Sources and Methods. A concordance between ISIC Rev.2 and ISIC Rev.3 classifications can be found in the United Nations Classifications Registry.
No effort has been made to make the new set directly compatible to the previous set, although in both sets of tables, the industry breakdown allows high-technology manufacturing activities, such as pharmaceuticals, computers, communication equipment and aircraft to be studied.
Many of the input-output tables have been derived from Member Countries' supply-use tables, using the industry-technology assumption. Furthermore, some additional adjustments have been made to the supply-use tables, usually to deal with disclosure problems. As such, the input-output tables should not be regarded as official country estimates. If the supply-use tables are consistent with equivalent estimates in the National Accounts and the STAN Database, the input-output tables maintain this consistency. Not all countries, however, integrate their supply-use tables into the national accounts' production process, and therefore on occasions differences may exist.
