The paper presents survey results from shopping behavior transformation in developed and developing countries due to the COVID-19 pandemic outbreak in spring 2020. The survey includes the polling process that covered 515 and 117 young adults, respectively, for two economies and factor analysis to determine the latent intentions of purchase behavior. Shopping patterns were studied for food, medicine, goods of first priority, electronics, clothing, and shoes. According to factor analysis results, we determined nine factors that reveal some similarities in shopping behavior as pro-safe purchases and belt-tightening patterns for both economies. Along with that, we revealed that people from developed countries perceived the greater danger and fear due to the COVID-19 crisis than young adults from developing economy. Based on polling results, the post–COVID-19 shopping channel choice behavior was evaluated for developed and developing economies.

The ongoing conflict in Ukraine has significantly disrupted global food supply chains, exacerbating existing food security challenges. To mitigate these disruptions, this study proposes a comprehensive approach to establishing sustainable intermodal terminals and technology parks along the Ukrainian–Polish border. To address this research issue, we analyzed the Ukrainian and global grain markets using publicly available statistical data. This analysis revealed the need to enhance grain transit through Poland, with terminal development identified as a crucial factor. Furthermore, a thorough analysis of the Polish freight rail transport market provided forecasts of potential demand for rail transit. Utilizing Petri nets as a modeling tool, we simulated the transit system at the macro level. Based on this simulation, we identified potential locations for freight terminals at the Ukrainian border near EU countries. Employing the AHP methodology, we evaluated these potential locations and selected Kovel in the Volyn region of Ukraine as the most promising alternative. For this location, we proposed the development of a new technological park. The implementation of this project, with the capacity to process and clear up to 600 wagons per day, would facilitate the transshipment of up to 3000 tons of grain per day from Ukraine to EU countries.
