Tactical repertoires of mobilization and repression play an essential role in understanding dynamics of political violence, yet existing quantitative approaches focus primarily on intensities or counts of repressive actions. We focus instead on the diversity of repression, and demonstrate a novel method of measuring repertoires of state repression using event data. We show that more repressive states are likely to employ more diverse repertoires of repression, rather than specializing narrowly in particularly coercive tactics. We demonstrate that, globally, repertoires of state repression are growing less diverse over time. Finally, in the Online appendix, we model repertoires of repression across countries and over time, finding evidence of broader repertoires during protest and civil war, but narrower under democratic regimes and international human rights treaties.

动员和镇压的战术手段在理解政治暴力的动态中起着至关重要的作用，但是现有的定量方法主要集中在镇压行动的强度或数量上。相反，我们专注于多样性压制，并演示了一种使用事件数据测量状态压抑库的新方法。我们表明，更多的镇压国家可能会采用更多的镇压手段，而不是狭particularly地专注于特别的强制性策略。我们证明，在全球范围内，国家镇压手段的多样性随着时间的流逝而越来越少。最后，在在线附录中，我们对国家和随着时间推移的镇压手段建立了模型，找到了在抗议和内战期间更广泛的手段的证据，但在民主制度和国际人权条约下却更窄。
