One of the most important and vital factors for establishing a knowledge based economy is making smart infrastructures. It is obvious that continuous evaluation of performance in these infrastructures is a very important factor. Science &Technology parks and Incubators are important infrastructures in these processes and continuous evaluation together with monitoring. For evaluation of S&T parks and Incubators, we need to consider: Initiating and formation cycle, goals, functions and actions, services and performance effects evaluation. In this paper we attempt to introduce some relevant parameters and measuring criteria based on experiments and literature review. Outputs, Added Value and best practices in S&T parks and Incubators are the main bases for introducing performance evaluation measurements.
