Purpose – the primary purpose of the study is to identify the main threats to the process of ensuring social security and finding ways to establish a connection between economic and social security. Research methodology – the methodological basis is a system of complementary philosophical, general scientific and unique methods of cognition of socio-political phenomena, in particular systemic-structural, comparatively retrospective, institutional and structural-functional, diagnostics and forecasting, general methods of analysis and synthesis, etc. Findings – our results made it possible to establish which particular threats most affect the social security of the countries of Eastern Europe and the calculation results will help establish the country needs a connection between economic and social security. Research limitations – we did not take into account a significant number of indicators characterising the state of social security of the state. The threats we have highlighted are compassionate. In the future, it is necessary to pay considerable attention to the process of assessing the level of social security of the state in order to determine whether it is necessary to state which government measures or not. Practical implications – сertain threats and models can be used by countries of Eastern Europe to form the necessary measures to counter them; Originality/Value – the study covers one of the least explored areas, namely social security, which has not been explored for a long time in the context of identifying threats. Social Security Model IDEF0 Formed.

The study contains an analysis of the essence of decentralization and its impacts on the creation of territorial communities. Scholarly views on the essence of the concept of ‘territorial community’ are presented and its features mentioned. The factors that determine the regional development of the territorial community as a subject of economic relations in the region have been identified. The legislative regulation of the process of creation and development of territorial communities is analysed and the shortcomings of the current situation are pointed out. The degree of decentralization over the period 2018–2020 is briefly analysed and a description of the methodology for assessing the viability of the created territorial communities is given. It is emphasised that the methodology of formation of affluent territorial communities is described in the 2015 Ukrainian legislation and approved by the resolution of 8 April No. 214 “The methodology of formation of affluent territorial communities”. The calculated indicators are given on the example of the Stepanivska united territorial community and its prospects of development are estimated. Recommendations for improving the conditions of formation and development of territorial communities in the conditions of decentralization in Ukraine have been developed. The empirical methodology used in the study proved to be liquid and can be applied in practice to the formation of the territorial community as a subject of local development.

The process of empirical substantiation of management activity in the context of existing requirements for ensuring the development of the public sphere is investigated. The relevance and necessity of such a justification is due to a number of postmodern factors, in particular, such characteristics of the indicated activity as versatility of implementation and direction, significant uncertainty of the premises, poly-subjectivity and value of reaching consensus. The essence of empirical substantiation is defined as the process of establishing the reliability of knowledge about the initial situation by applying a number of proven methods and measures. The difficulty of such an establishment is due to the fact that there is a fundamental opposition between knowledge and the real situation of objects reproduced by it. The justification of the reliability of empirical knowledge differs from the data similar to the content of scientific research and verification of data, since it includes taking into account the significance of the subject given to the subject of managerial activity. Given the subject-object nature of the latter, its empirical substantiation is carried out using a combination of natural science and humanitarian postmodern approaches. The position is substantiated that intersubjective certainty fundamentally differs from subjectivity and the lines of their distinction are drawn.
