Interest Groups in Multi-Level Contexts: European Integration as Cross-Cutting Issue in Party-Interest Group Contacts

Abstract

Policy-specific actor-constellations consisting of party- and group-representatives commonly drive the effective establishment of new policy programmes or changes in existing policies. In the EU multi-level system, the creation of such constellations is complicated because it practically requires consensus on two dimensions: the European public policy at stake and the issue of European integration. This means that, for interest groups with interests in particular policy domains, and with limited interest in the actual issue of European integration, non-Eurosceptic parties must be their main ally in their policy battles. We hypothesise that interest groups with relevant European domain-specific interests will ally with non-Eurosceptic parties, whereas interest groups whose interests are hardly affected by the European policy process will have party-political allies across the full range of positions on European integration. We assess this argument on the basis of an elite-survey of interest group leaders and study group-party dyads in several European countries (i.e., Belgium, Lithuania, Italy, Netherlands, Poland, and Slovenia) in a large number of policy domains. Our dependent variable is the group-party dyad and the main independent variables are the European policy interests of the group and the level of Euroscepticism of the party. We broadly find support for our hypotheses. The findings of our study speak to the debate concerning the implications of the politicisation of European integration and, more specifically, the way in which party-political polarisation of Europe may divide domestic interest group systems and potentially drive group and party systems apart.
