The Author evaluates the generalized Lowry model as an input-output model proposed by Macgill (1977) through its application to Toyota City. The main difficulty with operationalization is the virtual unavailability of a set of intersectoral input
-output coefficients for the city being studied. Thus, in estimating the input-output coefficients for Toyota City, the RAS or biproportional technique, which is one of the partial survey techniques, is used to adjust the coefficients for Aichi prefecture
