Research findings

Comparative structure study

The largest recorded reporting jurisdiction, Jiangsu, contains 9 records (29.0% of this 31-record cohort). The remaining cohort contains 22 records. The comparison concerns archive composition.

The recorded industry label Advanced materials accounts for 90.3% here (28/31), compared with 17.5% in the parent set (3,381/19,297), an absolute gap of 72.8 percentage points.

13/31 companies link to pages with existing source-supported excerpts (41.9% of the cohort). The other 18 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 Advanced materials covers 3,353/19,266 remaining records (17.4%), an absolute gap of 72.9 percentage points from this cohort.

Concentration and cross-sectional structure

The full reporting jurisdiction distribution has 14 labels; the top 3 contain 16/31 records (51.6%).Other known labels contain 15 records.

For 31 records with known labels, the effective category count is 7.2, versus 14 actual labels. Definitions and scope are in the methodology.

The table shows ten labels; 4 others are included in the calculations above.

Transparent rule reminderRecordsCohort share

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, “thermally conductive materials” has the most matches: 23/31. Name, product and sub-industry fields match 1, 4 and 22 records respectively; the largest field is sub-industry label. Fields can overlap, and a term remains a search link rather than verified business activity.

Intersection with 2026 local lists

9 of this cohort’s 31 records link through existing company-ID mappings to 2026 lists from all jurisdictions (29.0%). This intersection measures list linkage, not successful recognition or company growth.

Recorded roles and delivery checks

Material delivery requires stable-production evidence

The Insulating, heat-dissipating and thermally conductive materials label covers 21 records (67.7% of this cohort). This archive clue raises a verification question about Materials of defined composition and form with batch documents; it does not establish that these companies already deliver it.
