Indicators of socio-economic development of the regions of Ukraine demonstrate a tendency to increase disproportions, which are significantly intensified in the conditions of military operations. In addition to the deterioration of performance indicators, this trend leads to the fragmentation of the country's economic space. Regulation of regional development does not contribute to the reduction of disparities, in particular, due to shortcomings in the assessment, interpretation of indicators of disparities and modeling of their dynamics, which leads to the definition of unrealistic goals of regulation. Taking into account the need to ensure the connection between short-term and long-term planning of regional development, the purpose of the article is to develop theoretical and empirical foundations aimed at regulating dynamic processes in the indicators of regional development disproportions. To achieve the goal, the following tasks were chosen: to analyze the models of convergent-divergent processes of regional development imbalances, to build models of long-term interaction of indicators of imbalances in the spheres of life, to determine the basis for assessing the crisis dynamics of regional indicators. Methodology. To regulate the development of regions, a model of long-term interaction of indicators of disproportions in various spheres has been developed. The process component of the study of dynamic processes in the indicators of regional disproportions and forecasting of crisis situations in the spheres of regional activity, which covers the tasks, tools and main results of the study, has been formed. The paper investigates the long-run interaction of inequality indicators in different areas using econometric dynamic vector autoregressive and error correction models (VAR&ECM). This makes it possible to identify and predict non-stationary impulse processes in general, to identify trends relevant to individual phases of activity, to identify the relationship and interdependence of the trajectory of imbalances. The research tools are designed to solve a set of tasks on the regulation of imbalances. The originality of the article lies in the application of the modeling results in the form of interrelationships of disproportions for different time intervals in the formation of a set of programs and preventive measures to manage regional development disproportions. This also enhances the practical significance of the study. Practical implication. The data obtained as a result of the study of the dynamic processes of disproportion indicators can be taken into account in solving a set of tasks to regulate the disproportions of regional development, developing a set of measures for the implementation of regional strategies, financial and budgetary regulation of regional development, determining budget expenditures for solving problems arising from disproportions.

The paper analyzes the current state of financial and budgetary relations and their impact on the development of the region in conditions of external threats and internal instability, and defines the prospects for ensuring the regulation of social and economic processes in the region by financial and budgetary means. The importance of the formation of a modern conceptual and categorical apparatus of financial and budgetary relations for the development of the region based on the principles of the resource-activity approach is substantiated. Directions for improving the regulatory and legal basis for ensuring financial and budgetary relations for the development of the region are proposed, which will allow solving certain problems in the system of budgetary relations. It is noted that the implementation of foreign experience in regulating social and economic processes in the region by financial and budgetary means is designed to ensure a flexible response to external threats and overcome the consequences of internal instability. It is emphasized that an objective assessment of the level of socio-economic development of the region is a key indicator of the effectiveness of central authorities and local self-government. It is advisable to use a systematic approach to the comprehensive assessment of the level of socio-economic development of the region by components, which will allow to create a scientific basis for the effective distribution of budget funds within the framework of the implementation of goals, strategies and programs of sustainable development at both the national and regional levels. An important aspect of the research is the formation of an approach to the diagnosis of the influence of budget expenditures on the indicators of the development of the region in the aspect of an activity-logistics approach using economic and mathematical tools. The principles of forming the mechanism of financial-budgetary relations in ensuring the development of the region in the context of the activity-logistics approach based on the optimal distribution of budget funds when applying activity-logistics principles and evaluating their effectiveness are determined.
