Research Methodology

Desk research of MIIT procurement directives, SAMR enforcement records, and GB standards documentation preceded structured interviews with power module procurement managers at state-owned rail equipment manufacturers, EV platform engineers at BYD and NIO, SMIC foundry operations directors, and Jiangsu packaging facility technical leads. Secondary validation drew from customs trade data, semiconductor industry association reports, and SEC filings of foreign-headquartered suppliers. Bottom-up demand modeling and top-down supply capacity assessment were triangulated.

Assumptions held fixed include MEE dual carbon enforcement timelines and MIIT domestic content benchmark thresholds, while variables tested across the projection horizon encompassed SiC substrate supply elasticity and SAMR anti-monopoly review intensity. Segmentation dimensions modeled include product type, technology tier, end-use vertical, and regional manufacturing cluster. CAGRs were derived from shipment volume trajectories and average selling price movements across discrete and integrated solution categories. Forecast inputs incorporated EV production scaling curves and grid infrastructure investment pipelines.

Stress conditions across silicon carbide wafer supply disruptions, GB standards enforcement acceleration, and provincial subsidy program modifications were modeled; outcomes outside those bands fall beyond the analytical envelope.
