A company's position is determined by the products its annual report says it makes — with the original excerpt cited.

Where does the data on this map come from?

Two sources, styled differently on the map: relations tagged with a stock code are extracted from that company's annual report (click an edge to see the original Chinese excerpt and page); the backbone chain is an editorial framework that keeps the chain connected end-to-end. Company placements come 100% from disclosures — nothing is inferred.

Why do some items show no companies?

Dashed items have no collected annual-report disclosure yet — the segment may be dominated by non-Taiwan or unlisted players, or simply not yet covered. We deliberately distinguish "no companies" from "not yet covered".

Compiled from public annual-report disclosures for research and educational reference only — not investment advice or stock recommendations. The backbone chain is an editorial framework; company placements and code-tagged relations cite annual-report originals (in Chinese). Disclosures reflect their reporting period (FY2024 annual report, FY2025 annual report, FY2025 annual report, FY2026 annual report) and not current operations.
