THE POLYCRISIS AS A CHALLENGE TO THE RESILIENCE OF SOCIOECONOMIC SYSTEMS

The article examines the phenomenon of polycrisis as one of the key features of the current stage of development of the world economy and society. The relevance of the topic is due to the fact that modern socio-economic systems increasingly function under the simultaneous influence of several interrelated crisis processes. Economic instability, energy difficulties, geopolitical conflicts, social transformations, demographic changes and climate challenges no longer exist separately from each other. Their interaction forms a complex environment of constant uncertainty, in which even local problems can quickly develop into large-scale crisis phenomena. Under such conditions, traditional approaches to anti-crisis management gradually lose their effectiveness, since they are mostly focused on responding to individual crises, and not on their systemic and interdependent nature. That is why the problem of the stability of socio-economic systems acquires special importance both at the scientific and practical levels.The methodological basis of the study is formed on a combination of systemic, comparative and analytical approaches. The paper uses methods of analysis and synthesis to generalize modern approaches to the interpretation of polycrisis and the stability of socio-economic systems. The systemic approach made it possible to consider crisis processes as interconnected elements of a single unstable environment. The comparative method was used when studying the features of the functioning of socio-economic systems in different European countries and assessing their ability to adapt to crisis challenges. The paper also used elements of statistical analysis to assess the dynamics of stability indicators of European states during 2021–2025.As a result of the study, it was established that polycrisis is a much more complex phenomenon than a simple set of several crises. Its main feature is the close interaction of crisis processes, in which one crisis is able to strengthen another, forming new risks and increasing the overall level of instability. It is proven that the modern crisis environment is characterized by high unpredictability, difficulty in forecasting, and the systemic nature of the impact on socio-economic development. It was determined that the consequences of the polycrisis are manifested not only in the economic sphere, but also significantly affect social policy, the labor market, public administration, energy security and international economic relations. The analysis showed that countries with more effective state institutions, a higher level of digitalization, developed management mechanisms and a diversified economy demonstrate a better ability to adapt to crisis challenges and maintain stability even in conditions of prolonged uncertainty. At the same time, countries with a lower level of institutional capacity feel the consequences of the accumulation of economic, social and political shocks much more acutely.The practical value of the study lies in substantiating resilience as one of the key mechanisms for ensuring the stable functioning of socio-economic systems in modern conditions. It is proven that resilience should be considered not only as the ability to withstand crisis influences, but also as the ability to adapt to new conditions, recover from shocks and transform internal mechanisms of functioning in accordance with modern challenges. The results obtained can be used in the formation of public policy, the development of anti-crisis management mechanisms, increasing the efficiency of state institutions, and creating more adaptive development models in conditions of prolonged global instability.
