	Abstract: Alongside the neo-institutional model of networked
relations among universities, industries, and governments, the Triple Helix
can be provided with a neo-evolutionary interpretation as three selection
environments operating upon one another: markets, organizations, and
technological opportunities. How are technological innovation systems
different from national ones? The three selection environments fulfill
social functions: wealth creation, organization control, and organized
knowledge production. The main carriers of this system--industry,
government, and academia--provide the variation both recursively and by
interacting among them under the pressure of competition. Empirical case
studies enable us to understand how these evolutionary mechanisms can be
expected to operate in historical instances. The model is needed for
distinguishing, for example, between trajectories and regimes.
