Shortening supply chains – the prospect of international exchange

nr 2

24--33

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.

Z uwagi pojawiające się kryzysy różnej natury i sytuację geopolityczną podkreśla się, że konieczne jest tworzenie odpornych łańcuchów dostaw poprzez nearshoring. Efektem tego jest skracanie łańcuchów dostaw w przestrzeni zakupów materiałów i komponentów, czyli w sferze relacji zarządzania dostawami. Powinno to skutkować zmianami na poziomie wymiany handlowej w obszarze zakupów. Celem badania jest zatem zdiagnozowanie, czy istnieje tendencja do mniejszego obciążenia łańcucha dostaw z punktu widzenia dostaw międzynarodowych, czyli importu towarów. Przedmiotem rozważań jest Unia Europejska ze szczególnym uwzględnieniem Polski. Jako metodę badawczą do odkrywania natury zjawiska reprezentowanej przez sekwencję obserwacji oraz klasyczną statystykę opisową wykorzystano analizę szeregów czasowych. Stwierdzono m.in., że w Polsce i UE nie obserwuje się zmniejszenia obciążenia międzynarodowych łańcuchów dostaw wyrażonego wartościowo wolumenem wymiany handlowej. Dodatkowo, pomimo wzrostu kosztów transportu i polityki prośrodowiskowej, nie zaobserwowano pozytywnych zmian strukturalnych w kierunku skracania łańcuchów dostaw. Badania mogą pomóc w podejmowaniu decyzji dotyczących sposobów wzmocnienia odporności w przepływach towarów. Dotychczas badania na ten temat były prowadzone przeważnie w formie zagregowanej. Nowym wkładem badawczym jest dokonanie analizy uwzględniającej takie moderatory jak przepływy krótkie i długie.

Purpose: Nowadays there is still low awareness of creating specific supply chain hybrids in a planned manner. This paper focuses on a hybrid of the gresilient chain, which reflects the trend to act for the well-being of the environmental to eliminate disruptions in the flow of goods. The aim of the study is to determine the interdependence of the factors shaping the resilience of the supply chain and to determine which of them contribute the most to the creation of a green chain. Design/methodology/approach: AHP and DAMATEL were used as research tools. A study focused on the cognitive chain is extremely interesting, because it is a global chain in which the main coordinator is relatively small. The subject of the research is the international supply chain of a company that conducts research on engine oils, coolants and fuels for gas engines driving turbines, electric and wind turbines, hydraulic transmissions, etc. Findings: As a result, among other things, it was established, that speed is the factor that is most sensitive to the influence of other factors and, at the same time, the most important from the point of view of recipients. In addition, it was proven that redundancy is essential for creating resilience in the analyzed chain, while transparency is necessary for creating the green chain. It has also been shown that redundancy and cooperation work simultaneously to a great extent for the benefit of both chains. Research limitations/implications: Every supply chain requires a separate study. Practical implications: The results can help managers in implementing the gresilient strategy or in modifying it if it has already been implemented. The work carried out may contribute to the creation of a general matrix containing paths to the expected types of supply chains, taking into account the specificity of input and output connections. Social implications: Gresilient chains are part of the idea of corporate social responsibility. Originality/value: From the standpoint of building up resilience, this is an interesting case, because it is the discussed case does not fit into the concepts of popular models in which agility is promoted as the one that guarantees the resilience of the chain. The study is an expanding knowledge in the field of the gresilient chain, in which research is lacking due to the initial stage of science in this area.
