: 5; .: 2; .: 3; .: 11. Introduction. Modern processes taking place in Ukrainian society are characterized by a variety of directions of influence: on the one hand, they are unstable, transitive, stagnant, on the other -modernization, reformatory, reviving. Modern science is trying to consider approaches to stabilizing processes in the political, economic, social and cultural environment by proposing new ways to use the existing management tools, new management models both in the field of public authority (public administration) and in public administration, as well as mechanisms, implementation which provides for a new vision of the relationship «power -public» and is based on the national archetype.
The current conditions that have developed in the world have significantly stopped economic growth and only contributed to its destructuring. Ukraine is no exception in this situation and has a number of problems that in one way or another have a negative impact on the public administration system for economic development.
Keeping due to the scientific contribution of scientists and practitioners, it should be noted that today the question of the formation of a methodological approach to the definition and compilation of the main factors of influence on the public administration system of economic development remains open and urgent.
The task is to form, according to the proposed methodological approach, an appropriate model of hierarchical ordering of the impact of key factors on the system of public management of economic development.
The main purpose of the study is to form a methodological approach to the definition and compilation of the main factors of influence on the public administration system of economic development.
The research methodology. During the study, we used the methods of expert evaluation to determine the main factors influencing the system of public management of economic development and modeling methodology for the hierarchical organization of these factors using graph theory.
Results of the research. As a result of theoretical and practical research and expert assessment and a survey of leading experts in the field of public administration and economic development, we have identified the following factors that have the most negative impact on the public administration system of economic development (mathematical designations were established for each of the factors): -Coronavirus and its consequences (Z 1 ); -Political situation in the country (Z 2 ); -Inflationary processes (Z 3 ); -Regional tensions (Z 4 ); -Military aggression (Z 5 ); -Trust in Banking Systems (Z 6 ); -Trust in authority (Z 7 ). Graph theory is used to form a relationship graph. Suppose that the set of factors we have identified will have a set . From this set we choose a subset 2 1 Z Z ∈ of the most important factors. As a result, we get a graph of relationships between certain factors (Fig.1).
Matrix A of dimension 7 × 7 is presented in Table 1.
The reachability matrix for our modeling is presented in Table 2.
All elements presented in Table 2 must meet the requirement (3): Thus, if z j is achieved with z i , and there is a path in the graph that leads from the vertex z i to the vertex z j , then such a vertex is called achievable S (z i ). Similarly, the vertex z i is the precursor of the vertex z j if it reaches its vertex P (z i ) (4): (4) Note that also, an additional condition is to ensure equality (5): Thus, the implementation of the above actions forms the first level of the hierarchy of the factors we have defined. To determine it, we will form a corresponding calculation table (Table 3). Thus, the specified equality (5) is fulfilled by 2 and 6 factors, and it is those factors that form the lowest level of influence on the system of public management of economic development. This process is repeated until it is finally determined which factors have the greatest influence and which do not, due to their removal. Therefore, without unnecessary calculations, the hierarchy model of the influence of the main factors on the public administration system of economic development, presented in Fig. 2. Conclusions. The public administration system is a complex and complex structure, which, with the right approach, can significantly affect the economic development of the region and the country as a whole. However, the effective operation of the public administration system is impossible if there is a negative influence of a number of factors and factors that prevent it. That is why, we have formed a methodological approach to the definition and compilation of the main factors of influence on the public administration system of economic development. As a result, we have formed an appropriate model of the hierarchical influence of certain factors using the method of peer review and graph theory. Our research can have a practical aspect of application in public authorities. The research has limitations, which can be traced in the fact that only the economic environment of Ukraine was used as an object of research and in subsequent research, attention should be focused on the international level. and competitiveness.
