Research findings
Filter-difference study
Against the 13-record Smart Mining Coal Mine Intelligent Equipment Keyword Candidate Study, this 12-record cohort shares 12 records. Only 0 occur here and 1 only in the reference; the union contains 13. These are filter-membership differences, not company entries or exits.
| Company cohort | Directly linked pages | Share of public archive | Archive date |
|---|---|---|---|
| 12 | 12 | 0.1% | 2026-10-16 |
Deduplicated company IDs.
Filter differences and comparison link
The largest recorded sub-industry participation gap is for Instrumentation and testing equipment: 0/12 here versus 1/13 in the reference, an absolute difference of 7.7 percentage points. The cohorts have overlapping company IDs and are not independent samples.
| sub-industry | Focal count/base | Reference count/base | Participation gap (pp) |
|---|---|---|---|
| Instrumentation and testing equipment | 0/12 | 1/13 | -7.7 |
| Construction and heavy machinery | 2/12 | 2/13 | +1.3 |
| Advanced medical devices | 2/12 | 2/13 | +1.3 |
| Special-purpose machinery | 1/12 | 1/13 | +0.6 |
| Industrial wastewater-treatment equipment / smart environmental operations and maintenance | 1/12 | 1/13 | +0.6 |
Zero means no recorded label, not no business; multi-label cells overlap.
