Research Methodology

Bottom-up end-use demand modeling reconciled against top-down substrate supply tracking forms the analytical core of this study. Primary interviews with tier-1 automotive supplier procurement directors, domestic foundry operations managers, power module packaging engineers, and MIIT policy research fellows generated demand-side intelligence. Secondary validation drew from MIIT GB standard filings, NMPA automotive component registration databases, customs trade statistics for SiC wafer imports, and provincial industrial park investment disclosures. Triangulation between these sources established volume baselines and growth trajectory boundaries.

Input-output matrices map semiconductor device shipments across voltage class, substrate material, certification grade, and end-use application dimensions over the projection horizon. CAGRs derive from regression analysis of historical procurement patterns against EV production forecasts and industrial motor drive retrofit timelines.
