Research findings
Comparative structure study
The largest recorded industry, Advanced equipment, contains 30 records (33.0% of this 91-record cohort). The remaining cohort contains 61 records. The comparison concerns archive composition.
The recorded industry label Next-generation information technology accounts for 13.2% here (12/91), compared with 27.1% in the parent set (5,226/19,297), an absolute gap of 13.9 percentage points.
35/91 companies link to pages with existing source-supported excerpts (38.5% of the cohort). The other 56 records remain usable for archive composition, but do not support new operating case studies.

Excluding this cohort, the recorded industry label Next-generation information technology covers 5,214/19,206 remaining records (27.1%), an absolute gap of 14.0 percentage points from this cohort.
Concentration and cross-sectional structure
The full industry distribution has 10 labels; the top 3 contain 60/91 records (65.9%).Other known labels contain 31 records.
For 91 records with known labels, the effective category count is 5.2, versus 10 actual labels. Definitions and scope are in the methodology.
| Recorded label | Records | Share of cohort |
|---|---|---|
| Advanced equipment | 30 | 33.0% |
| Biomedicine | 18 | 19.8% |
| Next-generation information technology | 12 | 13.2% |
| Advanced materials | 11 | 12.1% |

| New-energy vehicles | 1 | 1.1% |
Record counts do not rank supply capability or economic size.
The largest intersection, Biomedicine × Biomedicine and medical devices / Complete systems and use-case applications, contains 14 records, or 77.8% of the 18 records carrying the Biomedicine label.

A rule hit prioritises review; it does not establish that the entire field is wrong. One record can trigger several rules.
1 records have a documented classification-consistency question. Original counts remain 91; excluding these records leaves 90 in the sensitivity calculation. The study does not reclassify firms or treat label conflicts as operating changes.
Intersection with 2026 local lists
14 of this cohort’s 91 records link through existing company-ID mappings to 2026 lists from all jurisdictions (15.4%). This intersection measures list linkage, not successful recognition or company growth.
| Observation set | List records | New-applicant records | Review records | Mapped company IDs |
|---|---|---|---|---|
| National list records linked to this cohort’s IDs | 14 | 0 | 14 | 14 |
| All list records in the same reporting jurisdiction | 26 | 12 | 14 | 26 |
The two rows are different sets; subtraction does not establish gaps or relocation. List rows are not new companies or final recognition.

The provincial macro sources below use a different denominator from this 91-record archive cohort; they do not establish individual operating results.
Can equipment demand be examined by delivery object when equipment and food-processing growth differ?
In 2025, Heilongjiang’s equipment industry above designated size grew by 8.4% in value added, with electrical machinery and general-purpose equipment up by 23.7% and 11.3%. Its food industry grew by 0.8%. Equipment deliveries and agricultural-processing demand therefore warrant separate verification. [1]
Interpretation and test conditions
Heilongjiang reported growth in both equipment and food industries in 2025, with different rates across electrical machinery, general equipment and food processing. Compare equipment producers with processors as separate record groups. Equipment-sector growth does not establish rising equipment purchases by food firms. [1]
General-equipment firms may serve several industrial uses. Check equipment objects and specifications for food-processing applications, then inspect documents concerning food contact, cleaning or testing. Counts of food-industry firms do not measure demand for a particular processing machine. [1]
Compare product terms, stated users and public delivery evidence for electrical and general equipment. Where records cluster, distinguish new-equipment production, repair and system services before discussing revenue sources or replacement demand. The current register does not provide purchasing cycles. [1]
