Regional trajectories of innovation in Green Chemistry: Evidence from the Aquitaine region (In French)
This article tries to apprehend the technological trajectories that develop in Aquitaine region in the field of green chemistry (GC). Breschi’s research works are used to stress that spatial patterns of innovation vary greatly amongst sectors according to the specific features of the underlying technology, as summarized by the concept of technological regime. In such a perspective, we take into account the role of industrial structures and technological regimes to apprehend regional trajectories of innovation in the field of GC. In order to characterize such trajectories, an empirical analysis is carried out by using patent data for the period 1990-2009. We end up with an original database of GC patents for the Aquitaine region which enables us to emphasize the concentration of innovative sources as well as the specialization fields in relation with the regional industrial structure.
