Research findings

Comparative structure study

The largest recorded reporting jurisdiction, Zhejiang, contains 18 records (16.8% of this 107-record cohort). The remaining cohort contains 89 records. The comparison concerns archive composition.

The recorded industry label New energy and power equipment accounts for 50.5% here (54/107), compared with 3.9% in the parent set (757/19,297), an absolute gap of 46.5 percentage points.

34/107 companies link to pages with existing source-supported excerpts (31.8% of the cohort). The other 73 records remain usable for archive composition, but do not support new operating case studies.

8 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 New energy and power equipment covers 703/19,190 remaining records (3.7%), an absolute gap of 46.8 percentage points from this cohort.

Concentration and cross-sectional structure

The full reporting jurisdiction distribution has 22 labels; the top 3 contain 38/107 records (35.5%).Other known labels contain 69 records.

For 107 records with known labels, the effective category count is 13.5, versus 22 actual labels. Definitions and scope are in the methodology.

The table shows ten labels; 12 others are included in the calculations above.

Transparent rule reminderRecordsCohort share
Contains registration-narrative wording10.9%

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

Matched fieldCandidatesCohort share

Recorded products9084.1%
Sub-industry98.4%

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, “switches” has the most matches: 86/107. Name, product and sub-industry fields match 19, 73 and 7 records respectively; the largest field is product field. Fields can overlap, and a term remains a search link rather than verified business activity.

Selected query termCandidates/shareName matchesProduct fieldSub-industry
switches86 · 80.4%19737

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.

8 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

22 of this cohort’s 107 records link through existing company-ID mappings to 2026 lists from all jurisdictions (20.6%). This intersection measures list linkage, not successful recognition or company growth.

Recorded roles and delivery checks

Component records require interface-level evidence

The Electronic assemblies and systems integration label covers 3 records (2.8% 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.
