Выявление однородных групп отраслей экономики Казахстана по уровню их инвестиционного обеспечения с использованием методов кластерного анализа.</p></sec><sec><title>Методология</title><p>Методология. Для исследования отраслевых инвестиций был применен метод кластерного анализа, основанный на группировке отраслей экономики по показателям инвестиционной активности. В качестве алгоритма кластеризации был взят K-means, с помощью которого было осуществлено распределение отраслей по трем кластерам. В исследовании была применена размерность с двумя компонентами PCA1 (первая компонента) и PCA2 (вторая компонента).</p><p>Оригинальность/ценность исследования. Полученные результаты закладывают основу для совершенствования инвестиционной политики путем согласования мер поддержки с конкретными потребностями и возможностями различных кластеров.</p></sec><sec><title>Результаты исследования</title><p>Результаты исследования. В результате кластерного анализа было выявлено три группы отраслей, внутренне однородных по исследуемому комплексу показателей инвестиционной активности. В кластере 0 объединены в основном инфраструктурные отрасли с высокой капиталоемкостью и небольшой экономической отдачей. В кластер 1 вошли отрасли, которые показывают высокую отдачу от вложенных инвестиций, но испытывают недостаток капитала. Кластер 2 сформирован из горнодобывающей промышленности со значительной долей инвестиций и высоким вкладом в развитие экономики страны.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Research purpose</title><p>Research purpose. This study applies cluster analysis methods to identify homogeneous groups of economic sectors in Kazakhstan according to their level of investment support.</p></sec><sec><title>Methodology</title><p>Methodology. To examine sectoral investment patterns, cluster analysis was conducted by grouping economic sectors based on indicators of investment activity. The K-means clustering algorithm was employed to classify the sectors into three distinct clusters. The analysis was carried out in a two-dimensional space using principal component analysis (PCA) with the first and second principal components serving as the axes. </p><p>Originality/Value of the Research. The findings provide a foundation for refining investment policy by aligning support measures with the specific needs and capacities of different sector clusters.</p></sec><sec><title>Findings</title><p>Findings. As a result of the cluster analysis, three group of sectors were identified, each internally homogeneous in term of the analyzed set of investment activity indicators. Cluster 0 primarily includes infrastructure-related industries characterized by high capital intensity and relatively low economic returns. Cluster 1 includes sectors that demonstrate high returns on investment but face capital shortages. Cluster 2 comprises the mining industry, which accounts for a significant share of investments and makes a substantial contribution to the country’s economic development. </p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>инвестиции</kwd><kwd>отрасли экономики</kwd><kwd>кластерный анализ</kwd><kwd>эффективность инвестиций</kwd><kwd>инвестиционная политика</kwd><kwd>отраслевой подход</kwd></kwd-group><kwd-group xml:lang="en"><kwd>investments</kwd><kwd>economic sectors</kwd><kwd>cluster analysis</kwd><kwd>investment efficiency</kwd><kwd>investment policy</kwd><kwd>industry approach</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">Macroeconomic report for 2024 and forecasts.
