This research explores the potential of smart transport systems as an infrastructural mechanism for stimulating the foreign economic activity of developing countries. It also presents practical and scientific recommendations for integrating these systems into the economic practices of such countries. Based on 2024 statistics, current as of the first half of 2025, the authors developed an econometric model using regression analysis to assess how smart transport systems can function as a mechanism for enhancing foreign economic engagement in developing nations. The model demonstrated that expanding the use of smart transport systems holds significant promise for strengthening foreign trade activities. It also revealed that the core of this mechanism lies in the telecommunications infrastructure and R&D support accompanying these systems. The novelty and fundamental significance of the author’s conclusions stem from their identification of the specific features of this infrastructural mechanism in the context of developing countries. The empirical value of this research lies in its forward-looking recommendations for optimizing smart transport systems in developing nations through 2030. By categorizing key system factors, these recommendations aim to improve the effectiveness of foreign economic policy.
