Research findings

Comparative structure study

The largest recorded reporting jurisdiction, Jiangsu, contains 53 records (22.2% of this 239-record cohort). The remaining cohort contains 186 records. The comparison concerns archive composition.

The recorded industry label Advanced equipment accounts for 81.2% here (194/239), compared with 25.5% in the parent set (4,918/19,297), an absolute gap of 55.7 percentage points.

114/239 companies link to pages with existing source-supported excerpts (47.7% of the cohort). The other 125 records remain usable for archive composition, but do not support new operating case studies.

13 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 equipment covers 4,724/19,058 remaining records (24.8%), an absolute gap of 56.4 percentage points from this cohort.

Concentration and cross-sectional structure

The full reporting jurisdiction distribution has 29 labels; the top 3 contain 93/239 records (38.9%).Other known labels contain 146 records.

For 239 records with known labels, the effective category count is 12.1, versus 29 actual labels. Definitions and scope are in the methodology.

The table shows ten labels; 19 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, “precision casting” has the most matches: 107/239. Name, product and sub-industry fields match 7, 11 and 90 records respectively; the largest field is sub-industry label. Fields can overlap, and a term remains a search link rather than verified business activity.

precision casting107 · 44.8%71190

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.

13 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

64 of this cohort’s 239 records link through existing company-ID mappings to 2026 lists from all jurisdictions (26.8%). This intersection measures list linkage, not successful recognition or company growth.

Recorded roles and delivery checks

Material properties require use-specific system validation

The Automotive structural parts and components label covers 8 records (3.3% of this cohort). This archive clue raises a verification question about Material-application assessments and system-validation documents; it does not establish that these companies already deliver it.
