Linkages between Energy Delivery and Economic Growth from the Point of View of Sustainable Development and Seaports

This paper presents the synchronisation of economic cycles GDP and crude oil products cargo volumes in major Polish seaports. On one hand, this issue fits into concept sustainable development including decoupling; on other may be an early warning tool. Crude are a specific barometer that predicts next cycle, especially as they primary sources energy production. The research study applies number TRAMO/SEATS methods, Hodrick–Prescott filter, spectral analysis, correlation cross-correlation function. Noteworthy is modern approach using tool, which was described paper. According to results, cyclical components traffic were affected by leakage short-term cycles. However, based cross-correlation, it proved changes preceded 1–3 quarters, valuable information for decision-makers planners.
