The Structural Power Index — Edition 2026 (Dataset & Report)

The Structural Power Index (SPI) is an independent annual index measuring structural power across twelve nations (US, China, Japan, Germany, France, UK, Italy, India, Russia, Canada, Brazil, South Africa), built on Susan Strange's theory of structural power from States and Markets (1988). It scores each nation across Strange's four structures — Security, Production, Finance, and Knowledge — over 21 hand-sourced, individually-cited metrics. This deposit contains Edition 2026 (methodology v2): structural-power-index-2026-data.json — the full machine-readable dataset: every nation, structure, metric, component score, reasoning, and source citation. state-of-structural-power-2026.pdf — the State of Structural Power 2026 report (analysis, methodology, key findings, data tables). A live, queryable version is published at structuralpower.org with a read-only REST API at api.structuralpower.org.
