The paper explores the application of the gravity model, namely the delineation of the urban predominant influence areas via the generation of the multiplicatively weighted Voronoi diagram, to the socio-economic regionalisation and administrative territorial division of Ukraine, including the existing state of affairs and several proposals on their improvement. The research uses quantitative statistical data on interregional migration and rail passenger traffic within the country, processed via the Statistica analytics software, and a subsequent spatial analysis conducted by GIS. The findings suggest that the gravity model can serve as a tool for optimisation the administrative territorial division, as well as for the delineation of the planning regions and urban hinterlands. At the same time, it has certain limitations and should not be treated as a panacea for regional planning and development.
Spatial rent (annuity) makes it possible to estimate the economic value resulting from the use of space for a given type of activity. This article provides calculations of spatial rent in regard to offshore wind energy development and proposes a data-driven approach for optimizing spatial management strategies, ultimately contributing to more informed decision-making processes in marine spatial management. It analyses seven projects that could be developed in the Polish part of the Baltic Sea as part of Poland’s energy transition. The article employs a robust methodology that integrates technoeconomic analysis and financial forecasting to calculate spatial rent by discounting net cash flows. The calculations are carried out for two windiness scenarios, with the results of the weighted average annual energy production ranging from 38.02 GWh/km2 to 40.56 GWh/km2. Such energy production could yield an annual spatial rent of 10.72 million €/km2 to 13.30 million €/km2.
