What this is
A research map, not an encyclopedia
The tracker is organized by stack segment first, then by company — so the focus stays on capability and bottlenecks, not on cataloguing every firm. It is not investment advice.
Where a strategically important business is a subsidiary, it still gets its own profile, even when the public-company economics roll up to a parent. The point is comparison: China's position against the global frontier, segment by segment.
What it covers
Segments, companies, and source-backed signals
- 17 stack segments — from compute and memory to equipment, materials, and sensing, each rated against the global frontier.
- 106 company profiles — Chinese anchors and strategically important subsidiaries, with global reference companies for comparison.
- Six capability ratings— from “leading” to “bottleneck,” applied per segment rather than per company.
- Live signals — revenue, market cap, capacity, customers, competitors, export-control exposure, and product qualification, with the source trail kept for audit.
How to read it
Alpha research on uneven evidence
This is early-stage research built on public sources of uneven quality. Listed companies disclose more than private subsidiaries; filings are more conservative than media reports; customer relationships are often indirect. A few things worth keeping in mind:
- Ratings are directional. They are segment-level judgments, not company rankings, and they should move when credible evidence changes the picture.
- Numbers need periods. A revenue, share, or capacity figure is only useful with its year, basis, currency, and source. Where those are missing, treat it as a signal, not a fact.
- Follow the source. The public page may compress caveats the backend keeps. When in doubt, open the source link on the profile.
Methodology
How the ratings work
A rating summarizes China's position in one segment against the global frontier. A stronger rating means credible domestic capability close to the frontier; a weaker one usually means the bottleneck sits in tools, materials, software ecosystem, qualification, yield, or export-controlled inputs. The same segment can rate differently by use case — good enough for EV or industrial substitution while still behind for frontier AI.
