Jiangxi / Advanced materials Company Structure Study

Comparative structure study

The largest recorded chain role, Advanced materials / Basic and process materials, contains 89 records (82.4% of this 108-record cohort). Companies may carry multiple labels in this dimension; participation rates are not additive market shares.

The recorded sub-industry label Metals and alloy materials accounts for 17.6% here (19/108), compared with 8.3% in the parent set (279/3,381), an absolute gap of 9.3 percentage points.

46/108 companies link to pages with existing source-supported excerpts (42.6% of the cohort). The other 62 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, Advanced materials, contains 3,381 records. This cohort contributes 108 (3.2%); 3,273 records remain after excluding it.

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

Excluding this cohort, the recorded sub-industry label Metals and alloy materials covers 260/3,273 remaining records (7.9%), an absolute gap of 9.6 percentage points from this cohort.

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.

10 of this cohort’s 108 records link through existing company-ID mappings to 2026 lists from all jurisdictions (9.3%). 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 Jiangxi uses a different denominator from this cohort.

Material delivery requires stable-production evidence

The Functional materials and advanced-material platforms label covers 38 records (35.2% of this cohort). This archive clue raises a verification question about Materials of defined composition and form with batch documents; it does not establish that these companies already deliver it.
