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

Comparative structure study

The largest recorded industry, Next-generation information technology, contains 181 records (89.6% of this 202-record cohort). The remaining cohort contains 21 records. The comparison concerns archive composition.

The recorded sub-industry label Electronic assemblies and systems integration accounts for 15.8% here (32/202), compared with 37.6% in the parent set (1,179/3,137), an absolute gap of 21.7 percentage points.

24/202 companies link to pages with existing source-supported excerpts (11.9% of the cohort). The other 178 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, Electronic information and digital technology / Core components and digital hardware, contains 3,137 records. This cohort contributes 202 (6.4%); 2,935 records remain after excluding it.

The parent set, Shanghai, contains 1,131 records. This cohort contributes 202 (17.9%); 929 records remain after excluding it.

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

Excluding this cohort, the recorded sub-industry label Electronic assemblies and systems integration covers 1,147/2,935 remaining records (39.1%), an absolute gap of 23.2 percentage points from this cohort.

The full industry distribution has 5 labels; the top 3 contain 199/202 records (98.5%).Other known labels contain 3 records.

For 202 records with known labels, the effective category count is 1.2, versus 5 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.

48 of this cohort’s 202 records link through existing company-ID mappings to 2026 lists from all jurisdictions (23.8%). 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 Shanghai uses a different denominator from this cohort.

Component records require interface-level evidence

The Electronic assemblies and systems integration label covers 32 records (15.8% 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.
