Research findings
Comparative structure study
The largest recorded industry, Advanced materials, contains 41 records (34.5% of this 119-record cohort). The remaining cohort contains 78 records. The comparison concerns archive composition.
The recorded industry label Advanced materials accounts for 34.5% here (41/119), compared with 17.5% in the parent set (3,381/19,297), an absolute gap of 16.9 percentage points.
25/119 companies link to pages with existing source-supported excerpts (21.0% of the cohort). The other 94 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 79/119 records (66.4%).Other known labels contain 40 records.
For 119 records with known labels, the effective category count is 5.1, versus 10 actual labels. Definitions and scope are in the methodology.

Intersection with 2026 local lists
33 of this cohort’s 119 records link through existing company-ID mappings to 2026 lists from all jurisdictions (27.7%). 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 | 33 | 2 | 31 | 33 |
| All list records in the same reporting jurisdiction | 69 | 38 | 31 | 69 |
The two rows are different sets; subtraction does not establish gaps or relocation. List rows are not new companies or final recognition.
Stored 2026 local-recommendation records, sources and stage definitionsProvincial context and cohort interpretation
The provincial macro sources below use a different denominator from this 119-record archive cohort; they do not establish individual operating results.
How should power-generation structure be separated from product-level green claims as materials and battery-related industries grow?
In 2025, the combined value added of Yunnan’s silicon-photovoltaic, green-aluminium and new energy battery industries grew by 16.9%. Clean energy represented 87.6% of electricity generated within the industrial above-designated-size scope. These provincial aggregates do not certify any individual company’s electricity source or products as green. [1]
Interpretation and test conditions
Yunnan reports combined value-added growth for silicon-photovoltaics, green aluminium and new-energy batteries, alongside the clean-energy share of industrial generation. One combines industries; the other describes power production. Separate materials and battery stages and retain energy context as a distinct condition. [1]
Verify each material firm's processes, equipment and end uses. A high provincial clean-generation share does not establish its purchased electricity, energy consumption or product carbon footprint. Location alone cannot confer green certification or a low-carbon price premium. [1]
Compare product forms and city distributions for silicon-related materials, aluminium processing and battery records, then check energy, performance and use evidence. Where the source gives only combined growth, do not allocate it to individual industries or estimate their contributions from firm counts. [1]
