Predictive models must consider nonlinear relationships among variables, such as using VAR models to analyze the dynamic association between the balance of payments and economic indicators.

Introduction

The modern global economy is increasingly dependent on interconnected supply chains, which span across continents, industries, and sectors. These networks, while efficient in optimizing resource allocation and reducing costs, also expose the system to vulnerabilities that can be exacerbated by geopolitical tensions, natural disasters, or pandemics. This article examines the structural dynamics of supply chain resilience, focusing on how economic policies, technological innovation, and institutional frameworks shape the ability of global supply chains to withstand disruptions. By analyzing case studies and theoretical models, the discussion highlights the interplay between economic stability and the durability of supply chain networks.

Structural Dynamics of Supply Chain Resilience

Supply chain resilience is defined as the capacity of a system to absorb disturbances and maintain functionality under stress. This concept is critical in an era where disruptions—such as trade wars, border closures, or technological shifts—can have cascading effects on economic output. The resilience of a supply chain is influenced by several factors, including the diversity of suppliers, the redundancy of critical nodes, and the level of technological integration.

One key determinant of resilience is supplier diversification. Economies that rely on a single source for critical components are more vulnerable to shocks. For
