Research findings

Comparative structure study

The largest recorded reporting jurisdiction, Jiangsu, contains 14 records (41.2% of this 34-record cohort). The remaining cohort contains 20 records. The comparison concerns archive composition.

The recorded industry label Advanced materials accounts for 82.4% here (28/34), compared with 17.5% in the parent set (3,381/19,297), an absolute gap of 64.8 percentage points.

13/34 companies link to pages with existing source-supported excerpts (38.2% of the cohort). The other 21 records remain usable for archive composition, but do not support new operating case studies.

6 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 industry label Advanced materials covers 3,353/19,263 remaining records (17.4%), an absolute gap of 64.9 percentage points from this cohort.

Concentration and cross-sectional structure

The full reporting jurisdiction distribution has 12 labels; the top 3 contain 21/34 records (61.8%).Other known labels contain 13 records.

For 34 records with known labels, the effective category count is 4.7, versus 12 actual labels. Definitions and scope are in the methodology.

The table shows ten labels; 2 others are included in the calculations above.

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, “alloy steel” has the most matches: 14/34. Name, product and sub-industry fields match 0, 14 and 0 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.

7 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

17 of this cohort’s 34 records link through existing company-ID mappings to 2026 lists from all jurisdictions (50.0%). This intersection measures list linkage, not successful recognition or company growth.

Recorded roles and delivery checks

Material delivery requires stable-production evidence

The Metals and alloy materials label covers 14 records (41.2% 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.
