Research findings

Comparative structure study

The largest recorded reporting jurisdiction, Jiangsu, contains 123 records (17.3% of this 713-record cohort). The remaining cohort contains 590 records. The comparison concerns archive composition.

The recorded industry label Energy conservation and environmental protection accounts for 84.6% here (603/713), compared with 4.5% in the parent set (869/19,297), an absolute gap of 80.1 percentage points.

272/713 companies link to pages with existing source-supported excerpts (38.1% of the cohort). The other 441 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 Energy conservation and environmental protection covers 266/18,584 remaining records (1.4%), an absolute gap of 83.1 percentage points from this cohort.

Concentration and cross-sectional structure

The full reporting jurisdiction distribution has 35 labels; the top 3 contain 248/713 records (34.8%).Other known labels contain 465 records.

For 713 records with known labels, the effective category count is 14.3, versus 35 actual labels. Definitions and scope are in the methodology.

The table shows ten labels; 25 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, “environmental protection equipment” has the most matches: 511/713. Name, product and sub-industry fields match 2, 6 and 505 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.

Intersection with 2026 local lists

142 of this cohort’s 713 records link through existing company-ID mappings to 2026 lists from all jurisdictions (19.9%). This intersection measures list linkage, not successful recognition or company growth.
