Research findings
Comparative structure study
The largest recorded chain role, Advanced materials / Basic and process materials, contains 232 records (71.4% of this 325-record cohort). Companies may carry multiple labels in this dimension; participation rates are not additive market shares.
The recorded chain role label Advanced materials / Basic and process materials accounts for 71.4% here (232/325), compared with 78.8% in the parent set (2,664/3,381), an absolute gap of 7.4 percentage points.
61/325 companies link to pages with existing source-supported excerpts (18.8% of the cohort). The other 264 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
77 of this cohort’s 325 records link through existing company-ID mappings to 2026 lists from all jurisdictions (23.7%). This intersection measures list linkage, not successful recognition or company growth.

Shandong Company Archive StudyRecorded roles and delivery checks
Material delivery requires stable-production evidence
The Functional materials and advanced-material platforms label covers 135 records (41.5% 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.
