Decision makers at all levels need sufficiently detailed information on regional economic structure in order to undertake consistent and comprehensive regional planning. A means is put forward here, elevating the impracticable regional input-output method, to that of an operational planning technique. This development represents a system which facilitates the examination both of the economic structure of individual regions in reasonable detail, and of the regional structure of the state economy. The technique, termed the Generation of Regional Input-Output Tables (GRIT), is designed for general use in the production of regional input-output tables, and other data sources contributing towards the holistic accuracy of the table, thereby providing accurate maximisation of input-output tables within a given budget constraint.
