Research findings
Comparative structure study
The largest recorded industry, Advanced equipment, contains 27 records (28.7% of this 94-record cohort). The remaining cohort contains 67 records. The comparison concerns archive composition.
The recorded sub-industry label Automotive structural parts and components accounts for 20.2% here (19/94), compared with 2.0% in the parent set (388/19,297), an absolute gap of 18.2 percentage points.
25/94 companies link to pages with existing source-supported excerpts (26.6% of the cohort). The other 69 records remain usable for archive composition, but do not support new operating case studies.

Excluding this cohort, the recorded sub-industry label Automotive structural parts and components covers 369/19,203 remaining records (1.9%), an absolute gap of 18.3 percentage points from this cohort.
Concentration and cross-sectional structure
The full industry distribution has 7 labels; the top 3 contain 67/94 records (71.3%).Other known labels contain 27 records.
For 94 records with known labels, the effective category count is 4.9, versus 7 actual labels. Definitions and scope are in the methodology.

Intersection with 2026 local lists
20 of this cohort’s 94 records link through existing company-ID mappings to 2026 lists from all jurisdictions (21.3%). 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 | 20 | 0 | 20 | 20 |
| All list records in the same reporting jurisdiction | 41 | 21 | 20 | 41 |
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 94-record archive cohort; they do not establish individual operating results.
Do component applications align with a falling vehicle total and rising new-energy output?
In 2025, Jilin’s vehicle output fell by 3.5%, while new energy vehicle output rose by 22.5%. Output of multiple-unit train vehicles and urban rail vehicles grew by 22.8% and 42.8%, respectively. Supplier analysis should distinguish vehicle segments and the different qualification systems used in automotive and rail equipment. [1]
Interpretation and test conditions
Jilin recorded lower total vehicle output but higher new-energy-vehicle output in 2025; multiple-unit trains and urban rail vehicles also increased. Separate end products before examining components. New-energy vehicles sit within the vehicle total, so their increase cannot be added to it. [1]
For automotive suppliers, examine whether products serve more than one powertrain route. Product documents must support the uses of structural parts, control systems or dedicated processes. A shift towards new-energy vehicles may change demand across stages, but output statistics cannot identify a firm's gain or loss. [1]
Group rail-equipment records by their own products and qualifications. Compare product overlap and evidence coverage between automotive and rail records to distinguish shared processes from dedicated systems. A high-end-equipment label cannot make that distinction. [1]
