Research findings
Comparative structure study
The largest recorded chain role, Advanced materials / Basic and process materials, contains 195 records (79.9% of this 244-record cohort). Companies may carry multiple labels in this dimension; participation rates are not additive market shares.
The recorded sub-industry label Advanced materials accounts for 16.0% here (39/244), compared with 3.0% in the parent set (102/3,381), an absolute gap of 13.0 percentage points.
67/244 companies link to pages with existing source-supported excerpts (27.5% of the cohort). The other 177 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
57 of this cohort’s 244 records link through existing company-ID mappings to 2026 lists from all jurisdictions (23.4%). This intersection measures list linkage, not successful recognition or company growth.

List rows and company IDs are separate counts, not new firms or final recognition.

Guangdong Company Archive StudyRecorded roles and delivery checks
Material delivery requires stable-production evidence
The Functional materials and advanced-material platforms label covers 88 records (36.1% 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.
