When two selection environments operate upon each other, mutual shaping in a
co-evolution along a particular trajectory is one possible outcome. When
three selection environments are involved, more complex dynamics can be
expected as a result of interactions involving bi-lateral and tri-lateral
relations. Three selection environments are specified in the Triple Helix
model: (1) wealth generation (industry), (2) novelty production (academia),
and (3) public control (government). Furthermore, this model somewhat
reduces the complexity by using university-industry-government relations for
the specification of the historical conditions of the non-linear dynamics.
Whereas the historical analysis informs us about how institutions and
institutional arrangements carry certain functions, the evolutionary
analysis focuses on the functions of selection environments in terms of
outputs. One can no longer expect a one-to-one correspondence between
institutions and functions; a statistics is needed for the evaluation of
how, for how long, and to what extent institutional arrangements enhance
synergies among different selection environments. The empirical
contributions to this Triple Helix issue point in the direction of "rich
ecologies": the construction of careful balances between differentiation and
integration among the three functions.
