In many different sectors, firms -not only technical departments, but also organizational structures- have been under the constant influence of technological improvements. The recent research in business literature shows that innovation and technology tactics, strategies and management style are important elements for success of companies in the market today. Earlier studies focus on the effects of these factors on firms' financial profit, market share position, and also success or problems of personal adaptation. Some argue that the firm age and structure are associated with the uniqueness of innovations in firms and suggest that once small and medium firms (SME) succeed in innovation through technological tactics, strategies and management directives, they can be easily imitated by their competitors. From this point, the present study examines the relationships between technological investments, firm size, firm age and innovation performance in Turkish firms which are in the technopolis at Middle East Technical and Hacettepe University, based on the firms' datasets and indicators in statistic mathods.
