Abstract
This paper conducts a comprehensive study of patent citations in patents granted to new economy firms in Belgium by the US and the EU Patent Offices using general qualitative response variable analysis, allowing for asymmetries in size and other characteristics. The citation data studied provide evidence of very industry-specific inter-, intra-firm and inter-, intra-industry knowledge spillovers. No general high-tech or new economy knowledge spillovers pattern was observed in the data. Therefore, we advocate for considering the industry-specific situation when analysing knowledge spillovers in the new economy.
