Research findings

Comparative structure study

The largest recorded reporting jurisdiction, Jiangsu, contains 174 records (16.7% of this 1,040-record cohort). The remaining cohort contains 866 records. The comparison concerns archive composition.

The recorded chain role label New energy and power equipment / Complete systems and use-case applications accounts for 63.7% here (662/1,040), compared with 9.1% in the parent set (1,763/19,297), an absolute gap of 54.5 percentage points.

395/1,040 companies link to pages with existing source-supported excerpts (38.0% of the cohort). The other 645 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 chain role label New energy and power equipment / Complete systems and use-case applications covers 1,101/18,257 remaining records (6.0%), an absolute gap of 57.6 percentage points from this cohort.

Concentration and cross-sectional structure

The full reporting jurisdiction distribution has 36 labels; the top 3 contain 371/1,040 records (35.7%).Other known labels contain 669 records.

For 1,040 records with known labels, the effective category count is 14.0, versus 36 actual labels. Definitions and scope are in the methodology.

The table shows ten labels; 26 others are included in the calculations above.

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

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, “new-energy equipment” has the most matches: 467/1,040. Name, product and sub-industry fields match 8, 7 and 460 records respectively; the largest field is sub-industry label. 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.

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

183 of this cohort’s 1,040 records link through existing company-ID mappings to 2026 lists from all jurisdictions (17.6%). This intersection measures list linkage, not successful recognition or company growth.
