Replication Data for: Coup-Proofing: Latent Concept and Measurement

The study of coup-proofing holds significant importance in political science as it offers insights into critical topics such as military coups, authoritarian governance, leader survival, and international conflicts. However, due to the multifaceted nature of coup- proofing and empirical inconsistencies with existing indicators, there is a need for a more profound understanding and a new measurement methodology. Despite growing discussions on a composite measure of coup-proofing, there are limited methodological attempts to develop a valid measure of coup-proofing. To address this gap, we propose a new measure of the extent of coup-proofing, utilizing a Bayesian Item Response Theory (IRT) approach. We estimate the extent of coup-proofing using a sample of 76 countries between 1965 and 2005 and theoretically relevant observed indicators. Our estimation reveals different patterns depending on the types of regimes across countries and time. Furthermore, we verify the construct validity of our measurement. Overall, our proposed measure contributes to the current scholarship on coup-proofing and provides a more accurate and reliable way of measuring this crucial concept.

防政变（coup-proofing）研究在政治学领域具有重要意义，因其可为军事政变、威权治理、领导人存续及国际冲突等核心议题提供研究视角。然而，由于防政变本身具有多面性，且现有衡量指标存在实证层面的不一致性，学界亟需对该议题形成更深入的认知，并探索全新的衡量方法。尽管学界对防政变的综合衡量指标讨论日益增多，但开发有效衡量工具的方法论尝试仍较为有限。为填补这一研究空白，本文采用贝叶斯项目反应理论（Bayesian Item Response Theory, IRT）方法，提出一种全新的防政变程度衡量指标。本文基于1965年至2005年间76个国家的样本，结合理论层面相关的可观测指标，对各国的防政变程度进行了估算。估算结果显示，不同国家、不同时期的政权类型会带来差异化的防政变模式。此外，本文还验证了所提衡量指标的结构效度。总体而言，本文提出的衡量指标为当前防政变相关学术研究提供了有益补充，并为这一核心概念的衡量提供了更为精准可靠的路径。
