Replication Data for: Elite Investments in Party Institutionalization in New Democracies: A Two-Dimensional Approach

This article conceptualizes party institutionalization and theorizes the conditions under which party elites invest in institutionalized parties in new democracies. We specify routinization and value infusion as two central dimensions of party institutionalization and theorize conditions relevant for party institutionalization across three central spheres: the party system, the state and society. Constructing measures for routinization and value infusion based on expert survey data, we test our framework through multivariate regression models across parties in 18 Latin American democracies. As theoretically expected, some conditions (access to executive office, a party’s formative environment and group ties) significantly relate to both dimensions, while others (party system polarization and fragmentation, permanent state subsidies, and legislative office) relate to one dimension only. This highlights the multidimensionality of party institutionalization as a phenomenon and the complexity of the empirical conditions associated with it.

本文构建了政党制度化（party institutionalization）的概念框架，并针对新民主国家中政党精英投资于制度化政党的条件开展理论推演。我们将常规化（routinization）与价值注入（value infusion）明确为政党制度化的两大核心维度，并从政党体系、国家与社会三大核心领域，推演了与政党制度化相关的各类影响条件。基于专家调查数据构建常规化与价值注入的衡量指标，我们针对18个拉美民主国家的各政党，采用多元回归模型对本文的理论框架进行实证检验。正如理论预期所示，部分影响条件（如获得行政职位、政党成长环境与群体纽带）对两大维度均存在显著关联，而其余条件（如政党体系极化与碎片化、永久性国家补贴与立法职位）则仅与单个维度相关。这一研究结果凸显了政党制度化作为一种社会现象的多维属性，以及与之相关的实证条件的复杂性。
