Research findings
Comparative structure study
The largest recorded chain role, Advanced materials / Basic and process materials, contains 256 records (85.3% of this 300-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 48.3% here (145/300), compared with 37.9% in the parent set (1,281/3,381), an absolute gap of 10.4 percentage points.
77/300 companies link to pages with existing source-supported excerpts (25.7% of the cohort). The other 223 records remain usable for archive composition, but do not support new operating case studies.

Intersection with 2026 local lists
77 of this cohort’s 300 records link through existing company-ID mappings to 2026 lists from all jurisdictions (25.7%). This intersection measures list linkage, not successful recognition or company growth.

Zhejiang Company Archive StudyRecorded roles and delivery checks
Material delivery requires stable-production evidence
The Functional materials and advanced-material platforms label covers 145 records (48.3% 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.
