Designing Multilevel Assessment model to evaluate science and technology parks using DEA

In knowledge base economy, performance evaluation of STPs as one of the most important entities in this economy is vital. In this research, we used literature review and industries expert interviews to determine what criteria are necessary to assess STPs. different topologies was used to assess the validity of the model and best model was chosen through highest reliability criteria. By comparison we made sure that selected criteria are reliably aligned with sience and technology parks objectives. On mathematical side we used robust multi-level DEA to assess STPs performances. We developed a Multi-level DEA with Non-Discretionary using banker's extension. Applying the developed model and the original model we assessed the efficiency of Iranian STPs.Then we compared the results for these two model on efficiency of DMUs, and their respecting weights using regression analysis. Based on the results two moderator variables (Park maturity and percentage of gross production in state) variable was identified and their impact on model and efficiency of DMUs was evaluated as high.
