The Impact of European Integration on the Development of Old Industrial Regions (the Experience of Lower Silesia for the Dnipropetrovsk Region)

The research conducted in this article is devoted to examining the current state of socio-economic development in regions of Ukraine and Poland that correlate according to certain indicators (Lower Silesian Voivodeship and Dnipropetrovsk Oblast). An analysis of the most successful cases of regional and local development in Poland is carried out with the aim of potentially utilising the opportunities of neighbouring countries and international interest in the relevant regions of Ukraine to accelerate their own development, which will be extremely relevant in the post-war period and in conditions of extreme shortage of own resources and financial opportunities. As a practical tool, proposals were made to use Polish experience in mechanisms for co-financing regional budget deficits, as well as in the organisation and functioning of cluster cases of energy self-sufficiency at the community level. The possibility and feasibility of applying these tools and methods at the regional level, for example, at the level of industrial macro-regions or regions of Ukraine, is justified.
