Assessment of the dynamics of steel production by countries of the world based on their grouping
Abstract. 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.
Keywords: metallurgical complex, steel industry, world steel production, grouping, cluster analysis, k-means clustering method.
Hightlightts:
- steel plays an important role in the modern economy and the development of modern society;
- global steel production is constantly growing, over the period 1950-2022 steel production increased by 9.97 times;
- in the process of conducting a cluster analysis of steel-producing countries, based on data for 2019 and 2023, 5 groups of steel-producing countries with corresponding characteristics were identified;
- based on the assessment, the logistics of the transition of steel-producing countries from one group to another has been determined.
