Research findings

Comparative structure study

The query term “structural parts” matches 436/531 candidates (82.1%). It can occur across products and industries; interpret the cohort by matched fields rather than treat every candidate as an operating business in this segment.

The largest recorded reporting jurisdiction, Jiangsu, contains 84 records (15.8% of this 531-record cohort). The remaining cohort contains 447 records. The comparison concerns archive composition.

The recorded industry label New-energy vehicles accounts for 69.5% here (369/531), compared with 5.0% in the parent set (960/19,297), an absolute gap of 64.5 percentage points.

209/531 companies link to pages with existing source-supported excerpts (39.4% of the cohort). The other 322 records remain usable for archive composition, but do not support new operating case studies.

Ratio of label participation, not market share; multi-label counts overlap.

Excluding this cohort, the recorded industry label New-energy vehicles covers 591/18,766 remaining records (3.1%), an absolute gap of 66.3 percentage points from this cohort.

Concentration and cross-sectional structure

The full reporting jurisdiction distribution has 29 labels; the top 3 contain 201/531 records (37.9%).Other known labels contain 330 records.

For 531 records with known labels, the effective category count is 13.1, 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, “die casting” has the most matches: 71/531. Name, product and sub-industry fields match 7, 49 and 18 records respectively; the largest field is product field. Fields can overlap, and a term remains a search link rather than verified business activity.

Selected query termCandidates/shareName matchesProduct fieldSub-industry
structural parts436 · 82.1%058395
die casting71 · 13.4%74918

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.

4 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

98 of this cohort’s 531 records link through existing company-ID mappings to 2026 lists from all jurisdictions (18.5%). 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 388 records (73.1% 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.
