Данное исследование посвящено количественной оценке влияния специализированных отраслевых конференций на ключевые показатели эффективности цепочек поставок. На основе квазиэкспериментального дизайна с применением метода «разность разностей» (Difference–in–Differences) и других эконометрических моделей анализируются данные о взаимодействии поставщиков и потребителей ЭКБ.</p><p>   Цель работы — определить роль конференций как инструмента снижения трансакционных издержек, проявляющихся в сокращении сроков согласования контрактов, уменьшении количества дефектов и повышении надежности поставок.</p><p>   Результаты показывают, что участие в конференциях статистически значимо сокращает время заключения сделок, снижает вероятность возникновения споров по качеству и уменьшает вариативность сроков поставки. Эмпирический анализ подтвердил, что участие в конференциях сократило время переговоров по контрактам в среднем на 12,8 % (p &lt; 0,01), что отражает снижение координационных издержек и повышение эффективности коммуникаций между участниками рынка. Особо выделена роль совместного участия инженерно–технических работников и специалистов по закупкам, которое оказывает более сильный положительный эффект по сравнению с участием только коммерческих представителей.</p><p>   Научная новизна заключается в применении строгих эконометрических методов для оценки неформального института координации и в интеграции подходов из теории трансакционных издержек и сетевого анализа.</p></abstract><trans-abstract xml:lang="en"><p>   Amid the growing volatility of global supply chains in the electronic component base (ECB) sector, companies face the urgent need to identify effective mechanisms for cost reduction and enhanced operational resilience. This study provides a quantitative assessment of the impact of specialized industry conferences on key performance indicators of supply chains. Using a quasi–experimental design with the Difference–in–Differences (DiD) method and complementary econometric models, the research analyzes data on interactions between ECB suppliers and consumers.</p><p>   The purpose of the study is to determine the role of conferences as a tool for reducing transaction costs, manifested through shorter contract negotiation times, fewer defects, and greater supply reliability.</p><p>   The results show that participation in conferences statistically significantly reduces deal finalization time, lowers the likelihood of quality-related disputes, and decreases the variability of delivery times. Empirical analysis confirmed that participation in conferences reduced the average contract negotiation time by 12.8 % (p &lt; 0.01), reflecting a decline in coordination costs and an improvement in communication efficiency among market participants. Particular attention is paid to the joint participation of engineering and procurement specialists, which has a stronger positive effect compared to the participation of commercial representatives alone.</p><p>   The scientific novelty of the study lies in the application of rigorous econometric methods to evaluate an informal coordination institution and in the integration of approaches from transaction cost theory and network analysis.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>цепочки поставок</kwd><kwd>трансакционные издержки</kwd><kwd>управление рисками</kwd><kwd>электронная компонентная база</kwd><kwd>отраслевые конференции</kwd><kwd>квазиэкспериментальный дизайн</kwd><kwd>сетевой анализ</kwd><kwd>эконометрическое моделирование</kwd></kwd-group><kwd-group xml:lang="en"><kwd>supply chains</kwd><kwd>transaction costs</kwd><kwd>risk management</kwd><kwd>electronic component base</kwd><kwd>industry conferences</kwd><kwd>quasi– experimental design</kwd><kwd>network analysis</kwd><kwd>econometric modeling</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">Литвин А.Л.
