Spatial dynamics of innovation (In French)

If it is largely assumed that space matters for innovation, theoretical understanding and measures of agglomeration remain a source of debates.

From the NEG to innovation systems, through localized knowledge spillovers and economics of proximity, the paper underlines the importance of geography in understanding innovation, but also the difficulties raised in doing so.Innovation; Space; Knowledge spillovers; Proximity; Clusters; Innovation systems
