Targeted industrial and sectoral subsidies (renewable energy, chip manufacturing, agriculture, green hydrogen, etc).
Product-market regulation, entry barriers, licensing burdens, network-industry regulation, price controls.
Received Royal Assent 28 April 2022 and came into force 4 January 2023, replacing EU State Aid rules with a UK-specific subsidy regime. Shifted from prior EU-style ex-ante Commission notification to an ex-post principles-based regime: public authorities self-assess subsidies against seven Subsidy Control Principles, with Competition and Markets Authority (Subsidy Advice Unit) oversight and Competition Appeal Tribunal review. Lowered administrative friction for low-value and regional-aid subsidies; created 'Subsidy of Particular Interest' and 'Subsidy of Interest' higher-scrutiny tiers.
Per invariant 3, reforms are scored by what they did on each channel-separated axis, not by the party that enacted them. This fingerprint is how the policy-match engine finds historical analogues.
Explicit links are curated by the author. Inferred links are hypotheses in the library that test the same axes this policy moved — the framework's answer to "what does the data say about a policy like this?".
Ranked by axis-fingerprint overlap with this policy. Direction match bolded — those are the closest historical analogues. Shape of the match is what drives policy-outcome comparison, not the country or party label.
