Due to the various crises and the geopolitical situation, it is emphasized that it is necessary to create resilient supply chains through nearshoring. The effect of this is the shortening of supply chains in the area of purchasing materials and components, i.e. in the sphere of supply management relations. This should result in changes at the level of trade in the area of purchases. The aim of the article is to diagnose whether there is a tendency to reduce the volume of supplies with the increase in the distance of supply sources from the perspective of their overall structure. The context of the considerations is the European Union, with special focus on Poland. Time series analysis was used as a research method to detect the nature of the phenomenon represented by a sequence of observations, as well as classic descriptive statistics. It was inter alia found that no reduction in the burden on international supply chains was observed in Poland and the EU, expressed in the volume of trade exchange in terms of value. Additionally, no positive structural changes towards shortening supply chains were observed, despite an increase in transport costs and pro-environmental policy. The research may support decision-making regarding ways to strengthen resilience in goods flows. Previously, research on this topic was usually conducted in an aggregate form. The new research contribution is an analysis that takes into account such moderators as short and long flows.
