Environmental protection equipment / Energy conservation, environmental protection and resource recycling / Complete systems and use-case applications Sub-industry and Supply-chain Study

Comparative structure study

The largest recorded reporting jurisdiction, Jiangsu, contains 56 records (18.3% of this 306-record cohort). The remaining cohort contains 250 records. The comparison concerns archive composition.

The recorded reporting jurisdiction label Beijing accounts for 4.2% here (13/306), compared with 8.1% in the parent set (56/693), an absolute gap of 3.8 percentage points.

121/306 companies link to pages with existing source-supported excerpts (39.5% of the cohort). The other 185 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 306 (44.2%); 387 records remain after excluding it.

The parent set, Environmental protection equipment, contains 329 records. This cohort contributes 306 (93.0%); 23 records remain after excluding it.

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

Excluding this cohort, the recorded reporting jurisdiction label Beijing covers 43/387 remaining records (11.1%), an absolute gap of 6.9 percentage points from this cohort.

The full reporting jurisdiction distribution has 29 labels; the top 3 contain 107/306 records (35.0%).Other known labels contain 199 records.

For 306 records with known labels, the effective category count is 13.4, versus 29 actual labels. Definitions and scope are in the methodology.

The table shows ten labels; 19 others are included in the calculations above.

Record counts do not rank supply capability or economic size.

The largest intersection, Jiangsu × Energy conservation and environmental protection, contains 54 records, or 96.4% of the 56 records carrying the Jiangsu label.

A cell contains company IDs carrying both labels. It does not establish procurement, supply or investment relationships between firms. Multi-label cells may overlap.

This page displays 8 of the full cross-tab’s 40 non-empty cells; the other 32 remain in the analysis.

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.

53 of this cohort’s 306 records link through existing company-ID mappings to 2026 lists from all jurisdictions (17.3%). 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.
