Regional economic resilience is a research field and academic concept examining the capacity of regional economies to anticipate, absorb, adapt to, and recover or transform following disruptive events or structural changes. It investigates the dynamic processes, structural characteristics, institutional frameworks, and endogenous capabilities that enable regions to maintain or restore economic performance, employment, and well-being in the face of adverse conditions. Significance lies in informing policy interventions aimed at enhancing regional robustness, adaptability, and transformative capacity for sustainable development.
