Research findings

Comparative structure study

The largest recorded reporting jurisdiction, Shandong, contains 6 records (12.0% of this 50-record cohort). The remaining cohort contains 44 records. The comparison concerns archive composition.

The recorded chain role label Advanced materials / Basic and process materials accounts for 80.0% here (40/50), compared with 14.8% in the parent set (2,854/19,297), an absolute gap of 65.2 percentage points.

12/50 companies link to pages with existing source-supported excerpts (24.0% of the cohort). The other 38 records remain usable for archive composition, but do not support new operating case studies.

9 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 2,814/19,247 remaining records (14.6%), an absolute gap of 65.4 percentage points from this cohort.

Concentration and cross-sectional structure

The full reporting jurisdiction distribution has 21 labels; the top 3 contain 16/50 records (32.0%).Other known labels contain 34 records.

For 50 records with known labels, the effective category count is 14.7, versus 21 actual labels. Definitions and scope are in the methodology.

The table shows ten labels; 11 others are included in the calculations above.

Record counts do not rank supply capability or economic size.

The largest intersection, Shandong × Advanced materials, contains 5 records, or 83.3% of the 6 records carrying the Shandong label.

A rule hit prioritises review; it does not establish that the entire field is wrong. One record can trigger several rules.

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, “graphite” has the most matches: 43/50. Name, product and sub-industry fields match 16, 34 and 9 records respectively; the largest field is product field. Fields can overlap, and a term remains a search link rather than verified business activity.

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.

9 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

12 of this cohort’s 50 records link through existing company-ID mappings to 2026 lists from all jurisdictions (24.0%). This intersection measures list linkage, not successful recognition or company growth.

Recorded roles and delivery checks

Material delivery requires stable-production evidence

The Carbon-based materials and carbon fibre label covers 20 records (40.0% 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.
