Research findings
Comparative structure study
The largest recorded industry, Advanced equipment, contains 52 records (69.3% of this 75-record cohort). The remaining cohort contains 23 records. The comparison concerns archive composition.
The recorded sub-industry label Instrumentation and testing equipment accounts for 12.0% here (9/75), compared with 17.1% in the parent set (700/4,085), an absolute gap of 5.1 percentage points.
40/75 companies link to pages with existing source-supported excerpts (53.3% of the cohort). The other 35 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 sub-industry label Instrumentation and testing equipment covers 691/4,010 remaining records (17.2%), an absolute gap of 5.2 percentage points from this cohort.
Concentration and cross-sectional structure
The full industry distribution has 5 labels; the top 3 contain 69/75 records (92.0%).Other known labels contain 6 records.
For 75 records with known labels, the effective category count is 1.9, versus 5 actual labels. Definitions and scope are in the methodology.
| Recorded label | Records | Share of cohort |
|---|---|---|
| Advanced equipment | 52 | 69.3% |
| Next-generation information technology | 12 | 16.0% |
| Biomedicine | 5 | 6.7% |
| Advanced materials | 3 | 4.0% |
| Producer services | 3 | 4.0% |
Record counts do not rank supply capability or economic size.

A rule hit prioritises review; it does not establish that the entire field is wrong. One record can trigger several rules.
Intersection with 2026 local lists
16 of this cohort’s 75 records link through existing company-ID mappings to 2026 lists from all jurisdictions (21.3%). This intersection measures list linkage, not successful recognition or company growth.

List rows and company IDs are separate counts, not new firms or final recognition.

Line delivery adds process-interface responsibilities
The Intelligent manufacturing line equipment label covers 2 records (2.7% of this cohort). This archive clue raises a verification question about Integrated process lines with system-acceptance documents; it does not establish that these companies already deliver it.
