Three Essays on Regionial Expertise Alignment and Inventive Performance

Abstract : This dissertation deals with how regions’ knowledge expertise affects the innovative performance in the region and contributes to the literature of regional innovation systems. The first chapter relies on the literature of regional innovation systems that underlines the role of spatial proximity on local innovative activities. Within the regional structure, two interconnected subsystems are well studied by scholars recently the knowledge-generation and the knowledge exploitation. I question traditional measurements and point out the limitations of current studies. I highlight the dynamics of regional knowledge subsystems as well as their relative relationships. I further suggest the new measurments of these knowledge subsystems at the finer-grained layers (i.e. different types of expertise in science and technology) by using a unique dataset of French patents and scientific publications (1990-2015), then examine their relationships with regional R&D expenditure. The results show that R&D expenditure has a positive relationship with the numbers of the scientific and technological expertise of the region; however, not to the level of expertise. I also show that the level of technological expertise will increase if it is complementary to a specific science. The second essay deals with the time value of local scientific expertise. In this study, we particularly extend the well-known literature of localized knowledge diffusion. We argue that local scientific expertise closely aligned with local industry enhances the ability of proximate inventors to recognize, access and acquire the potential scientific materials, particularly scientific publications, that favour for their innovation activities. As a result, it helps to reduce the time for local inventors to reference to scientific publications, hence increase the value of the invention. We measure the time lag between the published year of cited publications and citing patent to captures the fast diffusion of knowledge from scientific publication to the invention. The values of the focal innovation is captured by the direct and the multi-generational forward citation counts. The paper may help the scholar to better understand the different mechanisms for the diffusion of knowledge and/or interplay between science, innovation and technological progress. The third essay focuses on the region as a critical source for local inventors/firms by providing them with higher innovative capacities. We particularly elaborate on the concept of regional alignment by replying on the regional platform of knowledge systems. We take the view of knowledge generation that inventors combine different elements of knowledge to create an invention. During search process, inventors face different barriers and risks. We argue that the regional alignment as the effectiveness of knowledge platforms, which reflects potential synergies between complementary and heterogeneous knowledge expertise, competences and local actors. These synergies facilitate interactive learning, thus increase absorptive capacities to local actors. As a result, regional alignment may mitigate the risk and uncertainty of knowledge creation. These results show that regional alignment provides local actors with higher explorative capabilities to search and evaluate the distant knowledge, which helps to reduce variance and increase the usefulness of their explorative innovations.
