The state and tendencies of COVID-19 influence on the economic situation in the world are studied and the socio-economic losses suffered by the world economy during the pandemic are analyzed. The entire world community, starting in mid-December 2019, has come under the enormous influence of the World Coronavirus Epidemic, called COVID-19. The pandemic caused by this virus has already caused thousands of casualties around the world, imposed significant restrictions on the socio-cultural life of the population and radically changed the trends of the global economy. Today, it is difficult to predict what final human casualties and economic losses will be suffered by states in the short, medium and long term. However, it is important to consider individual economic development forecasts and measures selected by the governments of the world's leading countries to overcome the negative effects of the COVID-19 pandemic. This will allow to form a real vision of the possible course of economic processes that will directly affect the level of socio-cultural life of the population.and the real measures taken to stabilize the financial and economic situation at the micro and macro levels.

The article clarifies the essence of economic constitutionalism (constitutional economics) as an interdisciplinary doctrine. It is argued that economic constitutionalism (or constitutional economics) is the name of an interdisciplinary scientific field on the border of economics and constitutional law. In essence, economic constitutionalism is a special section of constitutionalism in general, which focuses on economics, property, the combination of private law and public law principles in the constitutional text, the theory of legitimate expectations, the economic nature of human rights and other constitutional legal objects regulation, ensuring de facto equality and establishing the limits of interference with economic freedom, financial and budgetary issues, the economic consequences of the concept of the welfare state and social human rights, etc. It is proved that economic constitutionalism is a promising interdisciplinary direction that integrates politics, constitutional law and economics. The importance of researching the economic nature of basic public and state constitutional institutions is beyond doubt. Similarly, the impact of relevant institutions, on the other hand, especially in the transition and transformation stages of development is enormous. The following main directions can be identified for further research on economic constitutionalism (constitutional economics), namely: consideration of law and the constitution as a manifestation of self-regulation; the role of property institutions, market economy, capitalism to ensure freedom; the need to ensure equality in order to implement rational choices, the interplay of democracy and social rights; the link between democratic transit and a market economy, exploring ways to grow and overcome poverty. The practice of interpretation of the constitution by the body of constitutional jurisdiction plays a significant role in economic constitutionalism. Analysis of the experience of the Ukrainian Constitutional Court in this aspect so far leads to the conclusion that its positions are inconsistent and, unfortunately, insufficient role in the constitutional economy (in terms of potential positive impact).

The concept of financial flows management of enterprise corporate security system is developed and justified in the article. The approaches to the assessment and analysis of the financial flow are analyzed. It is determined that the financial flow of enterprises' corporate security system should be understood as financial resources purposeful movement, which is a dynamic set in time and space within the logistics of processes at enterprises.The paper proves that the time factor is an important criterion for the industrial enterprise resource security management effectiveness because the duration of the time of any task depends on many interdependent cycles and parameters.It is emphasized that the vector of strategic goals in the multi-purpose model of integrated logistics processes at enterprises in a particular time period is complexly determined on the basis of various coefficients which are formed by the internal and external institutional environment analysis.It is confirmed that modeling of financial resources of integrated logistics processes makes it possible not only to form the optimal vector of strategic goals of the multi-purpose model of integrated logistics processes but also to identify the interconnection between the composition and volume of incoming and outgoing financial flows of all enterprise integrated processes. Material flow management optimization as a key aspect of logistics activities is considered, which is achieved by attracting and allocating financial resources and realized in the financial flows of integrated logistics processes at enterprises. The urgency of the requirements of coherence of material, financial, informational, and other types of resource flows of integrated logistics processes at enterprises is determined.It is proved the topicality and relevance of algorithms implementation for finding and analyzing performance indicators and decision-making criteria, which form the basis of the decision-making system for effective management of industrial enterprises’ resource potential, including financial, in conditions of factors instability and significant changes in the micro and macroeconomic environment.
