The current decade has stressed the reinforcement of three major trends
affecting developed economies since at least half a century. The frrst
trend concerns the im- portance of innovations for fIrms, regions and
nations. Even if innovation, however defmed, is not a recent phenomenon,
the crucial role innovativeness plays in a world of increased
competition reveals its importance as a major economic phe- nomenon. A
second prominent trend corresponds to the "tertiarisation of the econ-
omy", i. e. the considerable and continuous expansion of the share of
services in contemporary economies. 1 The third trend consists in the
substantial changes af- fecting the economical meaning of "space". Signs
of these substantial changes can be found in the increased unity of
"space" (the globalisation phenomenon), in the appearance of new
territories (as suggested by the emergence of a "virtual conti- nent"2)
as well as in the reconsideration of existing ones (for instance,
induced by new flexible production systems). As such, these three trends
express a triple break- down: a breakdown in the time scale of the
economy (due to the increasing velocity of economic activities), a
breakdown in the nature of the economy (since "intangi- ble production"
is expanding) and a breakdown in the space(s) of the economy (be- cause
of shifting dimensions). Certain categories of activities or actors may
high- light and even symbolise this triple rupture in diverse ways.
