Abstract
The COVID-19 pandemic has highlighted the fragility of the globally intertwined supply chains. Our primary motivation is to demonstrate a new networked-based multi-tier and multi-level analysis of the global supply chain of medical equipment, which is enabled by a novel approach in data mining of financial records of corporations at a global scale. This work may be a harbinger for future research focussed on select tiers and layers of networked supply chain data. The current research uncovers several previously unknown patterns of the global supply chain, including the role of tax haven nations, computer software/hardware industry, semiconductor industry, and motor vehicle and auto bodies in the medical equipment industry. Additionally, we conducted a deep supply chain network analysis and multiple simulation analyses of the supply chain network. The results reveal some new and important insights into the previously uncovered global supply chain network patterns as it relates to medical equipment.

Notes
3 Except for layers 1 & 2, the other networks represent a single industry. Node sizes represent eigenvector centrality. Node colors represent cluster membership. Layer 3 in is the single-tier value-chain network, which includes –but is not limited to– the supply chain.

5 The node colors identify clusters in the supply chain network. The node sizes illustrate eigenvector centrality.
6 Colors show the clustering algorithm result, and node sizes indicate eigenvector centrality. The color assignments in each networks in independent.
