Hunan / Electronic information and digital technology / Core components and digital hardware Company Structure Study

Filter-difference study

Against the 130-record Hunan / Next-generation information technology Company Structure Study, this 88-record cohort shares 84 records. Only 4 occur here and 46 only in the reference; the union contains 134. 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 Electronic assemblies and systems integration: 46/88 here versus 45/130 in the reference, an absolute difference of 17.7 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 Hunan uses a different denominator from this cohort.

Component records require interface-level evidence

The Electronic assemblies and systems integration label covers 46 records (52.3% of this cohort). This archive clue raises a verification question about Components or modules with application specifications; it does not establish that these companies already deliver it.
