Abstract An analysis was made of errors which can result from regional aggregation in spatial linear programming models. The agricultural sector of Portugal provided the empirical base for the analysis. Programming solutions were obtained first for eleven regions and then for three regions which were aggregates of the eleven regions. It is concluded that significant errors which resulted from this form of aggregation can be reduced or eliminated by intraregional stratification of production activities and resources and a priori specification of intraregional transport cost.
