Research findings

Comparative structure study

The largest recorded reporting jurisdiction, Zhejiang, contains 32 records (17.9% of this 179-record cohort). The remaining cohort contains 147 records. The comparison concerns archive composition.

The recorded chain role label Advanced equipment and industrial automation / Process equipment and inspection instruments accounts for 76.0% here (136/179), compared with 21.2% in the parent set (4,085/19,297), an absolute gap of 54.8 percentage points.

77/179 companies link to pages with existing source-supported excerpts (43.0% of the cohort). The other 102 records remain usable for archive composition, but do not support new operating case studies.

5 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.

Excluding this cohort, the recorded chain role label Advanced equipment and industrial automation / Process equipment and inspection instruments covers 3,949/19,118 remaining records (20.7%), an absolute gap of 55.3 percentage points from this cohort.

Concentration and cross-sectional structure

The full reporting jurisdiction distribution has 27 labels; the top 3 contain 78/179 records (43.6%).Other known labels contain 101 records.

For 179 records with known labels, the effective category count is 10.9, versus 27 actual labels. Definitions and scope are in the methodology.

The table shows ten labels; 17 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, “hydraulics” has the most matches: 148/179. Name, product and sub-industry fields match 72, 141 and 6 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
hydraulics148 · 82.7%721416
hydraulic systems69 · 38.5%1691

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.

5 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

42 of this cohort’s 179 records link through existing company-ID mappings to 2026 lists from all jurisdictions (23.5%). This intersection measures list linkage, not successful recognition or company growth.
