In the actor-centered institutionalist approach of Fritz Scharpf (1997), `a
ctor constellations' constitute the crucial link between substantive policy
analysis and interaction-oriented policy research. This paper presents an
attempt to conceptualize the `actor constellation' in a given policy domain
and to analyze it empirically with network analysis. The empirical context
is provided by the Swiss energy policy elite in the late 1990s - an exampl
e of a policy domain in transition between two policy equilibria. Based on
interviews with 240 of the core actors in this policy elite, the results sh
ow a characteristic antagonism between a pro-ecology and a pro-growth coali
tion. On the national level, the two coalitions are of comparable size and
power, which explains the current impasse in the policy domain in question.
Moreover, in a federalist state like Switzerland, the energy policy elite
is not concentrated at the center, but the basic antagonism is reproduced i
n each region nationwide. Confirming the consensus character of Swiss polit
ics, the different components of the two antagonist coalitions not only coo
perate within, but also across coalitions. These cooperative ties and the p
resence of honest brokers, policy enterpreneurs, and heterogeneous interest
s within each coalition provide opportunities for new alliances, which may
lead out of the current impasse in the more or less near future.
