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.

| Scope of source support | Count |
|---|---|
| Profiles with source-supported excerpts | 272 |

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

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

| Company name | 24 | 3.4% |
| Recorded products | 119 | 16.7% |
| Sub-industry | 634 | 88.9% |
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 query term | Candidates/share | Name matches | Product field | Sub-industry |
|---|---|---|---|---|
| environmental protection equipment | 511 · 71.7% | 2 | 6 | 505 |
| waste gas | 25 · 3.5% | 0 | 8 | 17 |
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.
| Observation set | List records | New-applicant records | Review records | Mapped company IDs |
|---|---|---|---|---|
| National list records linked to this cohort’s IDs | 142 | 7 | 135 | 142 |
List rows and company IDs are separate counts, not new firms or final recognition.

Assess environmental products against treatment media
The Environmental protection equipment label covers 329 records (46.1% of this cohort). This archive clue raises a verification question about Treatment equipment, materials or chemicals for defined objects; it does not establish that these companies already deliver it.
