Research findings
Comparative structure study
The largest recorded reporting jurisdiction, Jiangsu, contains 83 records (18.2% of this 456-record cohort). The remaining cohort contains 373 records. The comparison concerns archive composition.
The recorded chain role label Advanced materials / Basic and process materials accounts for 82.2% here (375/456), compared with 14.8% in the parent set (2,854/19,297), an absolute gap of 67.4 percentage points.
165/456 companies link to pages with existing source-supported excerpts (36.2% of the cohort). The other 291 records remain usable for archive composition, but do not support new operating case studies.
7 keyword candidates match only a company name, with no matching term in recorded products or sub-industry fields. Product evidence is needed before treating these as operating businesses in this segment.

Ratio of label participation, not market share; multi-label counts overlap.
Excluding this cohort, the recorded chain role label Advanced materials / Basic and process materials covers 2,479/18,841 remaining records (13.2%), an absolute gap of 69.1 percentage points from this cohort.
Concentration and cross-sectional structure
The full reporting jurisdiction distribution has 32 labels; the top 3 contain 176/456 records (38.6%).Other known labels contain 280 records.
For 456 records with known labels, the effective category count is 13.4, versus 32 actual labels. Definitions and scope are in the methodology.
The table shows ten labels; 22 others are included in the calculations above.

Non-empty fields are not necessarily accurate or supported by originals.
| Scope of source support | Count |
|---|---|
| Profiles with source-supported excerpts | 165 |
| Distinct corresponding companies | 165 |
| Reviewed Chinese/English paragraph pairs | 169 |
Counts concern existing reviewed bilingual excerpts, not re-certification of originals or entire reports.
| Transparent rule reminder | Records | Cohort share |
|---|---|---|
| Contains registration-narrative wording | 5 | 1.1% |
| Only generic operations vocabulary remains | 9 | 2.0% |
| Non-empty text shorter than five characters | 1 | 0.2% |
A rule hit prioritises review; it does not establish that the entire field is wrong. One record can trigger several rules.
| Matched field | Candidates | Cohort share |
|---|---|---|
| Company name | 96 | 21.1% |
| Recorded products | 156 | 34.2% |
| Sub-industry | 339 | 74.3% |
An ID may match several fields, so counts may exceed the cohort total. Matches establish search relevance only.
Among the translated non-broad query terms, “composite materials” has the most matches: 311/456. Name, product and sub-industry fields match 55, 72 and 200 records respectively; the largest field is sub-industry label. Fields can overlap, and a term remains a search link rather than verified business activity.
| Selected query term | Candidates/share | Name matches | Product field | Sub-industry |
|---|---|---|---|---|
| composite materials | 311 · 68.2% | 55 | 72 | 200 |
| carbon fibre | 112 · 24.6% | 5 | 22 | 97 |
Selected broad terms and specific segment terms, not the full query. Terms and fields can overlap and must not be summed. Counts show lexical sensitivity; no records are removed without primary evidence.
7 candidates match only a name, or lose all product-field matches after the full company name is removed while sub-industry also has no hit. This transparent string test locates copied company descriptions; it does not establish that a company does not operate the business.
Intersection with 2026 local lists
105 of this cohort’s 456 records link through existing company-ID mappings to 2026 lists from all jurisdictions (23.0%). This intersection measures list linkage, not successful recognition or company growth.
| Observation set | List records | New-applicant records | Review records | Mapped company IDs |
|---|---|---|---|---|
| National list records linked to this cohort’s IDs | 105 | 2 | 103 | 105 |
List rows and company IDs are separate counts, not new firms or final recognition.

Advanced inorganic materials need use-specific validation
The Polymers and composite materials label covers 185 records (40.6% of this cohort). This archive clue raises a verification question about Use-specific functional materials or components with validation documents; it does not establish that these companies already deliver it.
