Research findings
Comparative structure study
The largest recorded chain role, Advanced materials / Basic and process materials, contains 424 records (80.2% of this 529-record cohort). Companies may carry multiple labels in this dimension; participation rates are not additive market shares.
The recorded sub-industry label Functional materials and advanced-material platforms accounts for 41.4% here (219/529), compared with 37.9% in the parent set (1,281/3,381), an absolute gap of 3.5 percentage points.
296/529 companies link to pages with existing source-supported excerpts (56.0% of the cohort). The other 233 records remain usable for archive composition, but do not support new operating case studies.

A rule hit prioritises review; it does not establish that the entire field is wrong. One record can trigger several rules.
Intersection with 2026 local lists
151 of this cohort’s 529 records link through existing company-ID mappings to 2026 lists from all jurisdictions (28.5%). This intersection measures list linkage, not successful recognition or company growth.

| National list records linked to this cohort’s IDs | 151 | 0 | 151 | 151 |
List rows and company IDs are separate counts, not new firms or final recognition.

Jiangsu Company Archive StudyRecorded roles and delivery checks
Material delivery requires stable-production evidence
The Functional materials and advanced-material platforms label covers 219 records (41.4% of this cohort). This archive clue raises a verification question about Materials of defined composition and form with batch documents; it does not establish that these companies already deliver it.
