In the scientific discourse of the XXI century, the concept of modern Europe is being reformed under the influence of reforming the activities of the European Union. Scientific publications and research are conducted based on a study of the policies of the European Union countries, EU institutions and structural elements, and the problems that arise in the process of activity and development. The concept of modern Europe is a general term that embraces European values, the European standard of living, European policy, and European priorities, giving the concept of European studies a stable association with the European Union. In this context, the main causes and consequences for the scientific discourse, political practice, and future development of European countries must be considered. Neoinstitutionalists have attempted to analyse institutions based on atomistic methodology. Institutional transformations, processes of intra-European integration and enlargement of the EU, discussions on membership and exit from the EU raise issues of identity and development of governance in Europe. Europeanisation can be seen as a discourse, governance, and institutionalisation. The first interpretation emphasizes that modern Europe is a discourse, not only ideological but also administrative. In this sense, Europeanisation can be a means of expression of institutional globalization through domestic policy. In the article, the hypothesis is put forward and proved that the interpretation of the concept of modern Europe directly correlates with the future development of the European Union and its members. The dissemination of exclusive practices will help to spread the ideas of radical “Eurosceptics”, which could lead to the collapse of the European Union. The inclusive aspect of the concept of Europe is represented by the ideas of “Europeists” who, based on the common history, culture, mentality of the peoples of Europe, substantiate the positive influence on the state development of integration, non-state cooperation, and extrapolation of EU norms and principles into the new territories of Europe. There are three main reasons for shaping the concept of Europe as the boundaries of EU policy: The consolidation of political positions of the European Union and its growing role as an actor in world politics; Essence of the EU enlargement concepts; Features of development within the European community. The modern concept of Europe is considered in the context of a modern multi-level governance model. Therefore, Europeanisation is the interaction of different layers of interests, including structures of regional, multi-level governance, legitimacy of domestic and foreign policy. The impact of the multi-level governance system on the functioning of public administration systems in the Member States and neighbouring countries is considered. Four approaches are identified based on the analysis of relationships between different levels of governance. The necessity of formulating new theoretical paradigms defining the relations between the Member States and the technocratic institutions of the EU, as well as between the Europeanised system of national agencies and the ministries overseeing their activities, has been proved.
