Сталь представляет собой ресурс, который имеет фундаментальное значение в функционировании любого государства. Поэтому важна оценка динамики развития сталелитейной промышленности в различных странах мира на основе группировки. Методология включает в себя анализ финансовых показателей, статистические методы (логарифмирование, стандартизация, кластерный анализ), а также использование метода Данна для выбора оптимального числа кластеров. Целью работы является проведение кластерного анализа стран – производителей стали и выявление тенденций производства стали в этих странах с 2019 по 2023 г. Результаты группировки стран – производителей стали за 2023 г., проведенной при помощи кластерного анализа, позволили получить 5 групп с различными признаками. На основе оценки динамического изменения положения стран – производителей стали в составе полученных в ходе кластерного анализа групп в исследовании сделан прогноз их дальнейшего перемещения из группы в группу.</p></abstract><trans-abstract xml:lang="en"><p>Steel productionhas come to play a major role in the modern economy. Steel is a resource that is fundamental to the functioning of any nation. This is a basis of the dynamics of the development of the steel industry in various countries of the world on the basis of grouping. The methodology includes analysis of financial indicators, statistical methods (logarithm, standardization, cluster analysis), as well as the use of Dunn Index method to select the number of clusters. The purpose of the work is to conduct a cluster analysis of steel producing countries and identify steel production trends in these countries from 2016 to 2023. The results of groupings carried out using cluster analysis based on the results of producing countries starting in 2023 allow us to obtain five groups with different characteristics. Based on an assessment of the dynamic change in the position of steel-producing countries within the groups obtained during the cluster analysis, the study makes a forecast of their further movement from group to group.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>металлургический комплекс</kwd><kwd>сталелитейная промышленность</kwd><kwd>мировое производство стали</kwd><kwd>группировка</kwd><kwd>кластерный анализ</kwd><kwd>метод k-средних</kwd></kwd-group><kwd-group xml:lang="en"><kwd>metallurgical complex</kwd><kwd>steel industry</kwd><kwd>world steel production</kwd><kwd>grouping</kwd><kwd>cluster analysis</kwd><kwd>k-means clustering method</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Özgür A., Uygun Y., Hütt M.T.
