Magnetic Materials Ferrite Rare Earth Keyword Candidate Study

Comparative structure study

The largest recorded reporting jurisdiction, Zhejiang, contains 20 records (20.4% of this 98-record cohort). The remaining cohort contains 78 records. The comparison concerns archive composition.

The recorded chain role label Advanced materials / Basic and process materials accounts for 75.5% here (74/98), compared with 14.8% in the parent set (2,854/19,297), an absolute gap of 60.7 percentage points.

25/98 companies link to pages with existing source-supported excerpts (25.5% of the cohort). The other 73 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, All public archive records, contains 19,297 records. This cohort contributes 98 (0.5%); 19,199 records remain after excluding it.

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

Excluding this cohort, the recorded chain role label Advanced materials / Basic and process materials covers 2,780/19,199 remaining records (14.5%), an absolute gap of 61.0 percentage points from this cohort.

The full reporting jurisdiction distribution has 22 labels; the top 3 contain 43/98 records (43.9%).Other known labels contain 55 records.

For 98 records with known labels, the effective category count is 10.2, versus 22 actual labels. Definitions and scope are in the methodology.

The table shows ten labels; 12 others are included in the calculations above.

Record counts do not rank supply capability or economic size.

The largest intersection, Zhejiang × Advanced materials, contains 15 records, or 75.0% of the 20 records carrying the Zhejiang label.

A cell contains company IDs carrying both labels. It does not establish procurement, supply or investment relationships between firms. Multi-label cells may overlap.

This page displays 8 of the full cross-tab’s 42 non-empty cells; the other 34 remain in the analysis.

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.

An ID may match several fields, so counts may exceed the cohort total. Matches establish search relevance only.

Among the translated non-broad query terms, “permanent magnets” has the most matches: 87/98. Name, product and sub-industry fields match 8, 47 and 56 records respectively; the largest field is sub-industry label. Fields can overlap, and a term remains a search link rather than verified business activity.

Selected broad terms and specific segment terms, not the full query. Terms and fields can overlap and must not be summed. Counts show lexical sensitivity; no records are removed without primary evidence.

26 of this cohort’s 98 records link through existing company-ID mappings to 2026 lists from all jurisdictions (26.5%). 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.

Material delivery requires stable-production evidence

The Magnetic materials / rare-earth permanent-magnet materials label covers 54 records (55.1% 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.

Shared records with Rare Earth Permanent Magnet Materials Keyword Candidate Study: 97; records in this cohort but outside that set: 1. The intersection/union ratio is 49.0%, a measure of label overlap rather than business collaboration. Read comparison

Shared records with Permanent Magnet Motor Drive System Keyword Candidate Study: 14; records in this cohort but outside that set: 84. The intersection/union ratio is 12.7%, a measure of label overlap rather than business collaboration. Read comparison
