Research findings

Comparative structure study

The largest recorded reporting jurisdiction, Jiangsu, contains 14 records (15.4% of this 91-record cohort). The remaining cohort contains 77 records. The comparison concerns archive composition.

The recorded industry label Advanced materials accounts for 52.7% here (48/91), compared with 17.5% in the parent set (3,381/19,297), an absolute gap of 35.2 percentage points.

40/91 companies link to pages with existing source-supported excerpts (44.0% of the cohort). The other 51 records remain usable for archive composition, but do not support new operating case studies.

2 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.

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, “pipe materials” has the most matches: 73/91. Name, product and sub-industry fields match 4, 37 and 35 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.

2 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

23 of this cohort’s 91 records link through existing company-ID mappings to 2026 lists from all jurisdictions (25.3%). This intersection measures list linkage, not successful recognition or company growth.
