Chain membership
Source: TPEx 產業價值鏈資訊平台 (ic.tpex.org.tw) · captured 2026-08-22
This is the platform's own mapping of companies to chain nodes, not a disclosure made by each company. The capture date is when we read the platform, not a date anything was announced, so it is not safe to treat as point-in-time. Each read returns the newest capture: a company the platform has dropped disappears from this list rather than being marked as removed.
Node names and the platform’s own name appear in Chinese because that is the only form the source publishes them in. Translating them would put our wording on a classification that is not ours.

Monthly revenue, year on year
Reported monthly revenue compared with the same month a year earlier. A blank cell means that company reported no year-on-year figure for that month — not that revenue was flat.

Questions
1Where does this membership list come from?
From TPEx's own value chain platform, captured as a dataset. We do not add or remove companies. Every row on this page carries the authority it came from, and if a company is missing from the official platform it is missing here too.
2Why do some companies show no node?
Because the upstream capture does not record one for them yet. An unknown node is shown as unknown rather than guessed into a bucket, and those companies are still listed — dropping them would quietly shrink a membership list this page presents as complete.
3Can I use this list for a point-in-time backtest?
Not as it stands. The date on this page is when we read the platform, not a date on which anything was disclosed, and each read returns the newest capture — so a company the platform has dropped is simply absent rather than marked as removed. Reconstructing membership as it stood on a past date needs a disclosure date this dataset does not carry.
