Mapping the realignment of global value chains

Key takeaways

• The latest firm-level network data reveal that global value chains have lengthened, although without the accompanying network densification that might indicate that supplier relationships are diversifying.
• Lengthening of supply chains is especially significant for supplier-customer linkages from China to the United States, where firms from other jurisdictions, notably in Asia, have interposed themselves in the supply chain.
• Nevertheless, these recent developments have not so far reversed the long-running trend toward greater regional integration of trade in recent decades, especially in Asia.
