Research findings

Comparative structure study

The largest recorded reporting jurisdiction, Shenzhen, contains 18 records (30.0% of this 60-record cohort). The remaining cohort contains 42 records. The comparison concerns archive composition.

The recorded industry label Next-generation information technology accounts for 71.7% here (43/60), compared with 27.1% in the parent set (5,226/19,297), an absolute gap of 44.6 percentage points.

23/60 companies link to pages with existing source-supported excerpts (38.3% of the cohort). The other 37 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 Next-generation information technology covers 5,183/19,237 remaining records (26.9%), an absolute gap of 44.7 percentage points from this cohort.

Concentration and cross-sectional structure

The full reporting jurisdiction distribution has 17 labels; the top 3 contain 31/60 records (51.7%).Other known labels contain 29 records.

For 60 records with known labels, the effective category count is 7.3, versus 17 actual labels. Definitions and scope are in the methodology.

The table shows ten labels; 7 others are included in the calculations above.

Transparent rule reminderRecordsCohort share
Only generic operations vocabulary remains11.7%

A rule hit prioritises review; it does not establish that the entire field is wrong. One record can trigger several rules.

Matched fieldCandidatesCohort share

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, “acoustics” has the most matches: 27/60. Name, product and sub-industry fields match 4, 15 and 14 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.

Intersection with 2026 local lists

12 of this cohort’s 60 records link through existing company-ID mappings to 2026 lists from all jurisdictions (20.0%). This intersection measures list linkage, not successful recognition or company growth.

Recorded roles and delivery checks

Component records require interface-level evidence

The Acoustic and consumer-electronics components label covers 13 records (21.7% of this cohort). This archive clue raises a verification question about Components or modules with application specifications; it does not establish that these companies already deliver it.
