Abstract | |||||||||||||||||
Drawing on a large database of publicly announced R&D alliances, we
track the evolution of R&D networks in a large number of economic
sectors over a long time period (1986- 2009). Our main goal is to
evaluate temporal and sectoral robustness of the main statistical
properties of empirical R&D networks. By studying a large set of
indicators, we provide a more complete description of these networks
with respect to the existing literature. We find that most network
properties are invariant across sectors. In addition, they do not
change when alliances are considered independently of the sectors to
which partners belong. Moreover, we find that many properties of R&D
networks are characterized by a rise-and-fall dynamics with a peak in
the mid-nineties. Finally, we show that such properties of empirical
R&D networks support predictions of the recent theoretical literature
on R&D network formation.
