Zhejiang / Energy conservation, environmental protection and resource recycling / Complete systems and use-case applications Company Structure Study

Comparative structure study

The largest recorded industry, Energy conservation and environmental protection, contains 58 records (87.9% of this 66-record cohort). The remaining cohort contains 8 records. The comparison concerns archive composition.

The recorded sub-industry label Environmental protection equipment accounts for 31.8% here (21/66), compared with 44.2% in the parent set (306/693), an absolute gap of 12.3 percentage points.

18/66 companies link to pages with existing source-supported excerpts (27.3% of the cohort). The other 48 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, Energy conservation, environmental protection and resource recycling / Complete systems and use-case applications, contains 693 records. This cohort contributes 66 (9.5%); 627 records remain after excluding it.

The parent set, Zhejiang, contains 1,840 records. This cohort contributes 66 (3.6%); 1,774 records remain after excluding it.

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

Excluding this cohort, the recorded sub-industry label Environmental protection equipment covers 285/627 remaining records (45.5%), an absolute gap of 13.6 percentage points from this cohort.

The full industry distribution has 4 labels; the top 3 contain 64/66 records (97.0%).Other known labels contain 2 records.

For 66 records with known labels, the effective category count is 1.3, versus 4 actual labels. Definitions and scope are in the methodology.

Record counts do not rank supply capability or economic size.

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.

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

16 of this cohort’s 66 records link through existing company-ID mappings to 2026 lists from all jurisdictions (24.2%). 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.

The 2025 macro context for Zhejiang uses a different denominator from this cohort.

Assess environmental products against treatment media

The Environmental equipment and treatment systems label covers 23 records (34.8% 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.
