Hierarchical Regional Systems and the Politics of System Boundaries

Abstract

A hierarchical regional system may be defined as a regional international system composed of a single Great Power and a number of relatively small states. This article attempts to clarify the conditions under which member states of a hierarchical regional system, including both the great-power regional hegemon and the relatively small powers, seek to influence the salience that boundaries have for such a system. Scholars and policymakers alike may use several criteria in defining the boundaries of a regional system: 1) A system may be delimited geographically; 2) marked discontinuities in transactional interchanges (language, trade patterns, communication flows) may serve to set it off from the general international system as may common membership in formal international organizations; 3) boundaries may similarly be established by emphasizing behavioral criteria, i.e., by identifying norms especially pertaining to conflict management and resolution which are specific to a group of states. Unless otherwise specified, I employ the last definition throughout this article.
