Characterizing and comparing innovation systems by different ‘modes’ of knowledge production: A proximity approach

Though the concept of innovation systems has become influential in both academia and policymaking, an analytical approach to understanding innovation systems is still lacking. In particular, there is no analytical framework to measure `Mode 1? and `Mode 2? knowledge production. We propose a framework based on the proximity concept. Mode 1 and Mode 2 knowledge production are characterized by collaborations with cognitive, organizational, social, institutional and geographical proximity, and distance, respectively. Using a gravity model approach we apply our framework to the case of type 2 diabetes research and provide a characterization of the global innovation system and a comparative analysis of the North American and European innovation systems. Our main results hold that although collaborative research on type 2 diabetes generally follows a logic of proximity and hence is not characterized as Mode 2, important differences and similarities exist between the North American and European innovation systems.
