Power At Sea: A Naval Dataset, 1865-2011

Naval power is a crucial element of state power, yet existing naval datasets are limited to a small number of states and ship types. Here, we present 147 years of naval data on all the world's navies from 1865-2011. This country-year dataset focuses on warships with ship-based weapons capable of using kinetic force to inflict damage on other structures or peoples. This dataset provides variables of interest for use in country-year, dyadic, or systemic studies.海军力量是国家权力的关键构成要素，然而现有海军数据集仅覆盖少数国家与舰种类型。本研究发布了1865年至2011年间、跨度达147年的全球所有海军的相关数据集。该国家-年度（country-year）数据集聚焦于搭载舰载武器、可通过动能打击对其他设施或人员造成损毁的作战舰艇。本数据集可为国家-年度、双边或系统层面的研究提供所需的研究变量。
