Research findings

Comparative structure study

The largest recorded reporting jurisdiction, Jiangsu, contains 9 records (23.7% of this 38-record cohort). The remaining cohort contains 29 records. The comparison concerns archive composition.

The recorded industry label Next-generation information technology accounts for 50.0% here (19/38), compared with 27.1% in the parent set (5,226/19,297), an absolute gap of 22.9 percentage points.

10/38 companies link to pages with existing source-supported excerpts (26.3% of the cohort). The other 28 records remain usable for archive composition, but do not support new operating case studies.

3 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 Next-generation information technology covers 5,207/19,259 remaining records (27.0%), an absolute gap of 23.0 percentage points from this cohort.

Concentration and cross-sectional structure

The full reporting jurisdiction distribution has 15 labels; the top 3 contain 19/38 records (50.0%).Other known labels contain 19 records.

For 38 records with known labels, the effective category count is 8.5, versus 15 actual labels. Definitions and scope are in the methodology.

The table shows ten labels; 5 others are included in the calculations above.

Record counts do not rank supply capability or economic size.

The largest intersection, Beijing × Next-generation information technology, contains 4 records, or 80.0% of the 5 records carrying the Beijing label.

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, “wafers” has the most matches: 24/38. Name, product and sub-industry fields match 3, 20 and 1 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.

3 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

9 of this cohort’s 38 records link through existing company-ID mappings to 2026 lists from all jurisdictions (23.7%). This intersection measures list linkage, not successful recognition or company growth.

Recorded roles and delivery checks

Components and equipment carry different validation tasks

The Semiconductor manufacturing equipment label covers 4 records (10.5% of this cohort). This archive clue raises a verification question about Devices or process-specific equipment with corresponding test documents; it does not establish that these companies already deliver it.
