Systemic Trade Risk Suppresses Comparative Advantage in Rare Earth Dependent Industries

TL;DR

This study constructs a detailed trade network for rare earth elements, revealing tier-specific vulnerabilities and how systemic trade risks hinder the development of comparative advantage in key industries.

Contribution

It introduces a novel AI-augmented framework to analyze multi-tiered trade dependencies and classifies economies based on structural reliance on rare earths.

Findings

China dominates low-risk, high-influence cluster

EU and US remain vulnerable at intermediate tiers

High systemic trade risk impedes comparative advantage development

Abstract

Rare earth elements (REEs) are critical to a wide range of clean and high-tech applications, yet global trade dependencies expose countries to vulnerabilities across production networks. Here, we construct a multi-tiered input-output trade network spanning 168 REE-related product codes from 2007-2023 using a novel AI-augmented statistical framework. We identify significant differences between dependencies in upstream and intermediate (input) products, revealing that exposure and supplier concentration are systematically higher in input products, while systemic trade risk is lower, suggesting localized vulnerabilities. By computing network-based dependency indicators across countries and over time, we classify economies into five distinct clusters that capture structural differences in rare-earth reliance. China dominates the low-risk, high-influence cluster, while the EU and US remain vulnerable at intermediate tiers. Regression analyses show that high exposure across all products predicts future export strength, consistent with import substitution. However, high systemic trade risk in input products like magnets, advanced ceramics or phosphors, significantly impedes the development of comparative advantage. These results demonstrate that the structure of strategic dependencies is tier-specific, with critical implications for industrial resilience and policy design. Effective mitigation strategies must move beyond raw material access and directly address country-specific chokepoints in midstream processing and critical input production.
