Research findings
Comparative structure study
The largest recorded industry, Advanced equipment, contains 173 records (25.9% of this 667-record cohort). The remaining cohort contains 494 records. The comparison concerns archive composition.
The recorded industry label Next-generation information technology accounts for 19.5% here (130/667), compared with 27.1% in the parent set (5,226/19,297), an absolute gap of 7.6 percentage points.
267/667 companies link to pages with existing source-supported excerpts (40.0% of the cohort). The other 400 records remain usable for archive composition, but do not support new operating case studies.

Concentration and cross-sectional structure
The full industry distribution has 10 labels; the top 3 contain 465/667 records (69.7%).Other known labels contain 202 records.
For 667 records with known labels, the effective category count is 5.5, versus 10 actual labels. Definitions and scope are in the methodology.

A rule hit prioritises review; it does not establish that the entire field is wrong. One record can trigger several rules.
Intersection with 2026 local lists
152 of this cohort’s 667 records link through existing company-ID mappings to 2026 lists from all jurisdictions (22.8%). 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 | 152 | 6 | 146 | 152 |
| All list records in the same reporting jurisdiction | 327 | 181 | 146 | 327 |
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 667-record archive cohort; they do not establish individual operating results.
How should research distinguish industrial roles from spatial concentration when equipment and industrial-park shares overlap?
In 2025, equipment manufacturing in Hunan grew by 8.6% in value added and accounted for 33.9% of industrial value added above designated size. Industrial parks at provincial level or above accounted for 77.2% of industrial value added above designated size. These statistics help frame equipment and park-based research; a park address alone does not establish a company’s manufacturing capabilities. [1]
Interpretation and test conditions
Hunan reports shares of industrial value added above designated size for equipment manufacturing and for provincial-level-or-higher industrial parks in 2025. One classifies industries and the other locations; they overlap and cannot be added. Compare equipment roles with city distribution, then verify park membership. [1]
Firms in a park may deliver complete machines, components or production services despite sharing industry labels. Check products and intended applications. Co-location in a city or park is a spatial clue; evidence of transactions or projects is needed before describing a cooperation network. [1]
Compare equipment-subindustry counts and source coverage across cities, then calculate park membership only for verified records. If the register lacks a stable park field, report city distribution. The communiqué's park share cannot estimate the proportion of Little Giant firms located in parks. [1]
