Replication data for: \"Organizational and Ideological Strategies for Nationalization: Evidence from European Parties

How does a party's organizational structure affect its chances of becoming a national party? While existing explanations of party nationalization focus on country- level institutional and societal variables, we argue that aspects of party organization such as the degree of centralization of authority, ideological unity and leadership factionalism also matter. By bringing the analysis to the party level, this article provides a multilevel analysis of institutional and party organization variables and disentangles the effect of each set of influences. We use original data on party organization and party nationalization for 142 parties across 20 European countries. This research contributes to the literature on nationalization and party development by advancing organizational strategies which parties could adopt in different social and institutional environments.政党的组织结构如何影响其成为全国性政党的概率？现有关于政党全国化（party nationalization）的研究多聚焦于国家层面的制度与社会变量，而本文认为，政党组织的多项特征——包括权力集中程度、意识形态统一性以及领导层派系分化——同样至关重要。本文将分析视角聚焦于政党层面，针对制度与政党组织变量开展多层级分析，并厘清了两类影响因素各自的作用效果。本文使用覆盖20个欧洲国家、共计142个政党的政党组织与政党全国化原始数据。本研究丰富了政党全国化与政党发展领域的学术文献，并提出了政党在不同社会与制度环境中可采取的组织策略。
