This paper presents an appropriate model for Science and Technology Parks (STPs) with a view to helping policy makers and STP managers implement and manage STPs. The authors reorganize and prioritize the Cabral-Dahab Science Park Management Paradigm. We identify three critical groups of actors (determinants, reactors and executors) and develop four sub-models from different trajectories of the groups of actors. We place more emphasis on the “determinants” as the most important actors in the establishment and management of STP. A critical evaluation of the sub-models reveals that the sub-model in which government, industry and university/research institutes are all jointly involved in decisive policy direction is the most appropriate for the developing country. The paper concludes that economies in transition should see STPs as having a distinctive organizational structure as a result of its myriads of collaborations and partnerships.
