Inspection Testing Certification Keyword Candidate Study

Comparative structure study

The largest recorded reporting jurisdiction, Shanghai, contains 13 records (14.6% of this 89-record cohort). The remaining cohort contains 76 records. The comparison concerns archive composition.

The recorded industry label Producer services accounts for 62.9% here (56/89), compared with 4.9% in the parent set (954/19,297), an absolute gap of 58.0 percentage points.

21/89 companies link to pages with existing source-supported excerpts (23.6% of the cohort). The other 68 records remain usable for archive composition, but do not support new operating case studies.

An ID-deduplicated archive snapshot, not the whole market, current recognition or operating results.

The parent set, All public archive records, contains 19,297 records. This cohort contributes 89 (0.5%); 19,208 records remain after excluding it.

Ratio of label participation, not market share; multi-label counts overlap.

Excluding this cohort, the recorded industry label Producer services covers 898/19,208 remaining records (4.7%), an absolute gap of 58.2 percentage points from this cohort.

The full reporting jurisdiction distribution has 24 labels; the top 3 contain 33/89 records (37.1%).Other known labels contain 56 records.

For 89 records with known labels, the effective category count is 13.3, versus 24 actual labels. Definitions and scope are in the methodology.

The table shows ten labels; 14 others are included in the calculations above.

Record counts do not rank supply capability or economic size.

The largest intersection, Shanghai × Producer services, contains 12 records, or 92.3% of the 13 records carrying the Shanghai label.

A cell contains company IDs carrying both labels. It does not establish procurement, supply or investment relationships between firms. Multi-label cells may overlap.

This page displays 8 of the full cross-tab’s 48 non-empty cells; the other 40 remain in the analysis.

Non-empty fields are not necessarily accurate or supported by originals.

Counts concern existing reviewed bilingual excerpts, not re-certification of originals or entire reports.

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, “inspection and testing” has the most matches: 74/89. Name, product and sub-industry fields match 3, 74 and 0 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.

16 of this cohort’s 89 records link through existing company-ID mappings to 2026 lists from all jurisdictions (18.0%). 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.

Study professional services by outputs rather than equipment counts

The Instrumentation and testing equipment label covers 36 records (40.4% of this cohort). This archive clue raises a verification question about Design, inspection or technical outputs with defined scope; it does not establish that these companies already deliver it.

Shared records with Testing Laboratory Certification Services Keyword Candidate Study: 16; records in this cohort but outside that set: 73. The intersection/union ratio is 18.0%, a measure of label overlap rather than business collaboration. Read comparison
