Research on Development Assessment and Differentiation Paths of Second- and Fifth-Tier Cities Based on TOPSIS and Multidimensional Urban Resilience Models

Aiming at the development dilemma of second- and third-tier cities under the dual pressure of natural environment and economic fluctuation, this study proposes a comprehensive analysis method integrating TOPSIS and urban resilience assessment model. By quantitatively evaluating the industrial distribution and resilience performance of two typical cities, the study reveals the underlying mechanisms of their developmental differences: City 1 dominates in the field of community life services, but faces the challenges of lagging commercial finance and insufficient ecological resilience; while City 2 exhibits short-term economic vitality and planning efficacy, but weak production resilience and ecological management deficiencies constrain its ability to cope with risks. The study further proposes differentiated development paths: City 1 needs to strengthen the synergy between ecological management and industrial upgrading, while City 2 should prioritize strengthening the foundation of production resilience and gradually optimize public services. The model provides city managers with a decision-making tool that balances short-term efficiency and long-term sustainability through the allocation of multi-dimensional indicator weights and a dynamic evaluation mechanism.
