Details

Supply chains are critical structures which determine the flow of inputs and outputs through the economy. Changing technologies and global trade have shaped these overlapping chains into a complex supply network, leading to both opportunities and vulnerabilities.

This report provides a foundation for:

• documenting where market power sits across the supply network
• placing UK supply chains in a global context
• analysing how external shocks can propagate through supply networks
