Technoparks are economic public policy tools. Their success depends on government-backed support mechanisms, incentives and legislation, and the services and programs provided by the management companies. Today in Turkey, it might not be easy to measure the effectiveness of technoparks in nation's growth and development since there are too many parameters involved. This article elaborates on the effectiveness of technoparks in generating the desired benefits within the framework of the current technology and innovation policies and the potentials of the resident companies. The hypothesis is that, despite the involvement of complex public management aspects, the capacity and the potential of the technopark companies appear as the most critical parameters. Nevertheless, the performance of the companies will determine the value that the technoparks shall add to economic growth and development.
