Input-Output Tables (IOTs) describe the sale and purchase relationships between producers and consumers within an economy. The OECD IOTs database is a very useful empirical tool for economic research and structural analysis at the international level as it highlights inter-industrial relationships covering all sectors of the economy.
Input-Output tables (IOTs) can either show flows of final and intermediate goods and services defined according to industry outputs (industry × industry tables) or according to product outputs (product × product tables).
The OECD harmonised national Input-Output tables take the industry × industry approach. This allows better integration with collections of statistics compiled according to industrial activity such as R&D expenditure, employment, foreign direct investment and energy consumption.

The IOTs are intimately related to the OECD’s Inter-Country Input-Output (ICIO) tables.
