ABSTRACT

The basis of the table was the 1963 provisional input–output table of the C.S.O. and the disaggregated transactions were built up "from underneath" in that technical coefficients were constructed and then multiplied by total Outputs to form transactions. As part of the work on an econometric analysis of the construction industry at the Building Research Station, it was decided to investigate the building of an input–output model, disaggregated for construction into eight sectors and some other sectors supplying construction. If the industries are grouped, by the indirect input to construction expressed as a direct input, out of the nineteen industries which had the largest share of indirect inputs, seven of them have been apportioned pro rata from building types as we have no Information about them. A better model would be one in which sales of construction to capital Investment could be shown in fact, if we had a capital matrix, this would then be of considerable interest to construction.
