Participation and Political Influence in Complex Governance Systems

Public policy generally emerges from interactions among actors embedded within complex governance systems, composed of multiple actors and forums (issue‐based arenas where stakeholders repeatedly interact to resolve collective action problems). Such systems allow actors multiple forums wherein they can influence policy decisions. But actors do not value the decisions made in each forum equally, and it remains unclear how actors allocate resources across forums. This article links actor strategy to their influence within the forums the actors identify as most important (their primary forum). There is theoretical ambiguity about how actors invest their limited resources across the forums that affect their interests to maximize primary forum influence. Do they concentrate all their effort within the primary forum or participate more broadly? To answer this question, we offer two competing theories. First, broad participation may allow actors to develop political capital necessary to influence other actors and thus influence primary forum policies. The second approach notes the opportunity costs of broad participation—actors have fewer resources to invest in their primary forum. An analysis of stakeholder participation in the Sacramento–San Joaquin River Delta and Tampa Bay Watershed governance systems demonstrates that broader participation is associated with greater primary forum influence.
