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

Filter-difference study

Against the 151-record Jiangsu / Energy conservation and environmental protection Company Structure Study, this 129-record cohort shares 122 records. Only 7 occur here and 29 only in the reference; the union contains 158. These are filter-membership differences, not company entries or exits.

An ID-deduplicated archive snapshot, not the whole market, current recognition or operating results.

The largest recorded sub-industry participation gap is for Environmental protection equipment: 56/129 here versus 55/151 in the reference, an absolute difference of 7.0 percentage points. The cohorts have overlapping company IDs and are not independent samples.

Zero means no recorded label, not no business; multi-label cells overlap.

Multi-label counts can overlap; filter compliance is not industrial advantage.

Existing excerpts do not certify entire old reports; list linkage is not final recognition. Full definitions are on the series page.

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