Insularity or Solidarity? The Impacts of Political Opportunity Structure and Social Movement Sector on Alliance Formation

In: Mobilization: An International Quarterly, Band 16, Heft 3, S. 303-324

Abstract

Past democratization processes revealed a rise of interorganizational collaboration between social movement organizations. This paper investigates this sociopolitical phenomenon by analyzing the conditions under which alliances form within or across social movement industries in the context of democratizing Korea. A negative binomial regression analysis examines the impacts of the political opportunity structure and the social movement sector on different forms of protests: single, intramovement, and intermovement protests. Statistical results show that various dimensions of the political opportunity structure render differential effects, rather than a uniform effect, on alliance patterns. At the organizational level, coalitions and organizational diversity positively affect all forms of protests. The establishment of a strong alliance structure broadly empowers movements by providing a locus of organizational interactions and supports.
