Abstract
<jats:p>The article examines the transformation of the organizational and economic mechanism of state influence on the economy in conditions of war and post-war recovery. The relevance of the research is determined by the need to develop an effective system of public governance capable of ensuring the resilience of the economic system under large-scale external shocks and structural transformations. Theoretical approaches to the concept of economic resilience and adaptability of socio-economic systems are analyzed. Particular attention is paid to modern interpretations of resilience in economic science, which emphasize the ability of economic systems not only to recover from shocks but also to transform their structure and development trajectory. It is substantiated that the integration of adaptability and resilience principles provides a methodological basis for improving the mechanism of state influence in crisis conditions. The study proposes the concept of an adaptive-resilient mechanism of state influence, which is interpreted as a dynamic system of institutional, economic, social, and security instruments of public policy. The functioning of the mechanism is based on several key principles, including phase transformation, structural flexibility, resource mobility, institutional continuity, social justice, and digital governance. A structural-functional model of the adaptive-resilient mechanism of state influence is developed. The model includes four interacting functional blocks: security, economic, social, and institutional. Their interaction determines the level of economic resilience and effectiveness of public policy implementation. The study emphasizes that the dominance of particular blocks changes depending on the phase of economic development. To ensure methodological consistency, the study introduces a mathematical formalization of the integral efficiency of the mechanism of state influence. The proposed approach considers the variable weights of functional blocks depending on the phase of economic development. This allows the mechanism to adapt to changes in the external environment and ensures structural flexibility in public policy. In addition, a transformation matrix of the mechanism of state influence is developed. The matrix reflects the relationship between phases of economic development, dominant policy instruments, budget priorities, and expected outcomes of state management. The phases include mobilization, stabilization, reconstruction, and strategic development. The scientific novelty of the research lies in the conceptualization of the adaptive-resilient mechanism of state influence and the development of a dynamic structural-functional model that allows adjusting public policy priorities depending on the phase of economic development. The practical significance of the research results lies in the possibility of applying the proposed approach for improving the effectiveness of economic policy in wartime conditions and during post-war recovery.</jats:p>
