The supply chain vulnerability indicator co-developed by Dr. INOMATA Satoshi, a Chief Senior Researcher at the IDE-JETRO, and Dr. HANAKA Tesshu, Associate Professor of Kyushu University has been officially adopted and published by the Organisation for Economic Co-operation and Development (OECD) as part of its official statistics.

In global supply chains, the pursuit of optimal resource allocation often leads to the concentration of critical production capacities in specific countries. However, in an increasingly uncertain global economy, these production hubs can swiftly become "choke points" of the entire economic systems.

To address this issue, the OECD has released the Pass-Through Frequency (PTF) Indicator, developed by Dr. Inomata and Dr. Hanaka. This indicator identifies potential vulnerabilities and concentration risks within supply chains at various stages of production processes.

The OECD website offers full access to the downloadable datasets, with brief description of the indicator and its analytical examples.
