The concept of innovation networks has become popular among academics of various disciplines and policy-makers. Though innovation network concept has been used in national, sub-national or sectoral innovation analyses and policy development, it has not been utilized enough at the international levels such as political institution building both in the transition countries and in the European Union enlargement. It is the belief of the author that although all nations have experienced unique trajectories in transition to knowledge-based economy, they are all advised to utilize networking between the users and producers of knowledge as a prevalent policy-tool to utilize the benefits of knowledge-based economy. This similar modus operandi of the national innovation programs would less complicate the enlargement of EU especially concerning the establishment of a common research area and cooperation in innovation.
