The relationships between the agents integrating innovative spaces are essential for the development and success of these spaces. This article analyses the networks of relationships occurring in several technological areas. Our aim is to verify whether they follow or not the same pattern. These networks may be studied from a reticulated perspective, on the basis of the companies´ attributes and the relational variables generated between them, as well as from the search for a quantitative explanatory model point of view. The empirical analysis has been made in three Technological Parks and its outcome shows that the structure of the networks is influenced by the growth strategy put in place by the management of the parks, taking into account the industrial conditions of their geographical area. The quantitative analysis confirms the core-periphery model observed in the networks.
