Statutory and effective corporate tax rates, treatment of depreciation, and international competitiveness.
Phased reduction of Thailand's standard corporate-income-tax rate from 30% to 23% (tax year 2012) and to 20% (tax years 2013-2014, subsequently extended) via Royal Decree No. 530 of 20 December 2011 under the Yingluck government. SME rate structure also lowered. Intended to improve regional competitiveness vs ASEAN peers (Singapore 17%, Malaysia 25%). Implemented alongside minimum-wage hike creating a supply-side-plus-demand-side policy mix; corporate-tax cut became the most durable element of the Yingluck programme, retained under subsequent Prayut junta.
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.
