Abstract
Advances in geographical information systems have contributed to location andmarketing
design strategies on the part of retailers. The techniques used in this field are based on
delimiting trade areas and spatial analysis. The same approach is applied in this study
to technology centres, which are considered as suppliers of knowledge-intensive
services to their associated firms. The research objective focuses on analysing the
spatial distribution of firms associated with two technology centres from different
sectors. The results indicate that firms associated with a technology centre present
spatial patterns that are similar to those observed in retailing, while significant
differences were also found between the two technology centres used for the study
