Research on Economic Resilience Assessment and Improvement Strategies for Small and Medium-sized Cities and Specific Regions

In recent years, economic resilience has attracted much attention as an important concept in responding to external shocks. However, there are relatively few studies on the economic resilience of cities of different sizes, especially small and medium-sized cities and specific regions. This study analyzes the economic resilience of small and medium-sized cities and specific regions, explores the concept, influencing factors, and evaluation methods, and analyzed previous studies. Through the analysis of previous studies, this article discusses in detail the research results on the economic resilience of mega-cities, sub-provincial cities, and Northeast China, including data selection, method use, research results, and conclusions of related studies. This study provides a comprehensive evaluation and analysis of the economic resilience of small and medium-sized cities and specific regions and formulates corresponding improvement strategies. The research results on the economic resilience of megacities, sub-provincial cities, and the Northeast region provide important reference and guidance for policymakers in this field, and provide a basis for improving economic resilience and formulating urban development strategies.
