Reasons for stagnation in river transport in Poland at the turn of the 20th and 21st centuries

The aim of the study was to identify the causes of the progressive stagnation in Polish river shipping (Polish inland navigation) since the middle of the 20th century. The methodology used, due to the type of research, was of a complex, eclectic nature. It was based on the analysis of empirical data, desktop research studies, a systemic analysis of relations and cause-and-effect relationships in the sphere of river transportation, and a critical interpretation of the goals contained in program documents on the development of river shipping. The studies focused on the macroeconomic level. The results obtained not only identified the causes of stagnation, but also indicated the most urgent directions for research in this area. Their implementation may allow to design such a strategy for the development of river shipping in Poland, thanks to which it will become an important part of the economy and sustainable transport. The research is original and unknown in this form in the Polish literature.
