This study examines the research connectivity of Russian regions by looking at the publication activity of local authors, more specifically, geographic proximity, the number of co-authored articles, and the similarity of research topics shaping economic trends. The study employs bibliometric analysis of 1,846 articles published in 2023 across 53 Russian peer-reviewed economic journals, authored by 3,102 researchers. A textual analysis of article abstracts, using TF-IDF and cosine similarity measures, was conducted to determine the similarity of research topics. Key findings show that the distance between regions has minimal impact on the connectivity of the scientific economic space and researcher collaboration. Instead, connectivity is more strongly influenced by the level of collaboration, especially at the interregional level. Drawing on these findings, the study outlines strategies for improving regional connectivity, for example, developing research networks that align with regional industrial, technological, and scientific specializations. It also highlights the role of major “scientific” regions (based on their publication volume) and the importance of supporting collaboration between smaller regions and these leaders. These hubs can help develop regional research potential and facilitate the spatial implementation of joint project outcomes.</p></abstract><abstract xml:lang="ru"><p>Укрепление научно-исследовательских связей регионов, отвечающих за снижение барьеров распространения знаний между ними, а также усиление эндогенного взаимодействия субъектов хозяйствования для совместного решения технологических проблем страны, является одной из важных стратегических задач развития национальной экономики. Целью исследования является разработка и апробация методического подхода к анализу научно-исследовательских связей регионов, выявляющего интенсивность межрегионального сотрудничества в контексте географической близости авторов, количества совместных статей, а также схожести тематик исследований. Методическую базу исследования составляет библиометрический анализ 1 846 статей, опубликованных в 2023 году в 53 российских рецензируемых экономических журналах, с общим количеством авторов 3 102 человека. Для определения схожести тематик статей использовался текстовый анализ аннотаций, основанный на применении меры TF-IDF и косинусном сходстве. В качестве основных результатов исследования выявлены следующие корреляции: расстояние между регионами оказывает незначительное влияние как на связанность научного экономического пространства, так и на уровень коллаборации между исследователями из разных регионов; связанность научного экономического пространства (как на внутрирегиональном, так и на межрегиональном уровне) напрямую зависит от уровня коллаборации между исследователями, причем на межрегиональном уровне эта зависимость проявляется в большей степени, чем на внутрирегиональном. Также на основе анализа определены условия укрепления научно-исследовательских связей регионов, а именно выстраивание научно-исследовательских сетей с учетом промышленно-технологической и научной специализации регионов, а также наделение драйверной ролью крупных «научных» регионов (по показателю количества публикаций) и оказание поддержки в поиске и реализации новых форм их взаимодействия с другими территориями. Локомотивы научных исследований смогут развивать исследовательский потенциал регионов — участников научных коммуникаций и обеспечивать пространственное внедрение полученных результатов совместных проектов.</p></abstract><kwd-group xml:lang="en"><kwd>research networks, connectivity of regions, scientific economic space, geographical proximity, joint articles, scientific interaction, bibliometric analysis, text analysis, TF-IDF measure, cosine similarity</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>научно-исследовательские связи, связанность регионов, научное экономическое пространство, географическая близость, совместные статьи, научное взаимодействие, библиометрический анализ, текстовый анализ, мера TF-IDF, косинусное сходство</kwd></kwd-group></article-meta></front><body/><back><ack xml:lang="en"><p>This    paper     was   prepared as  part    of the   state    assignment from    the   Ministry of Education and   Science of the Russian Federation to  the   Institute of Economics, Ural    Branch of RAS    (2024), research topic No.   0327–2024-0015: “Methodologyfor the Formation of a New Model of Sustainable Economic and Spatial Development of Industrial Regions”.</p></ack><ack xml:lang="ru"><p>Статья выполнена в  рамках государственного задания Минобрнауки РФ    для     ФГБУН  Институт  эко-номики УрО  РАН    на   2024    год,   тема НИР No 0327–2024-0015 «Методология формирования новой модели устойчивого и  экономически безопасного пространственного развития индустриальных регионов».</p></ack><ref-list><ref id="en-ref1"><label>1</label><mixed-citation xml:lang="en">Adams, J.
