Dalian Company Structure Study

Comparative structure study

The largest recorded sub-industry, Electronic assemblies and systems integration, contains 7 records (6.5% of this 107-record cohort). Companies may carry multiple labels in this dimension; participation rates are not additive market shares.

The recorded industry label Next-generation information technology accounts for 15.9% here (17/107), compared with 27.1% in the parent set (5,226/19,297), an absolute gap of 11.2 percentage points.

37/107 companies link to pages with existing source-supported excerpts (34.6% of the cohort). The other 70 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 107 (0.6%); 19,190 records remain after excluding it.

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

Excluding this cohort, the recorded industry label Next-generation information technology covers 5,209/19,190 remaining records (27.1%), an absolute gap of 11.3 percentage points from this cohort.

The table shows ten labels; 42 others are included in the calculations above.

Record counts do not rank supply capability or economic size.

The largest intersection, Advanced equipment × Advanced equipment and industrial automation / Process equipment and inspection instruments, contains 21 records, or 53.8% of the 39 records carrying the Advanced equipment 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 32 non-empty cells; the other 24 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.

25 of this cohort’s 107 records link through existing company-ID mappings to 2026 lists from all jurisdictions (23.4%). This intersection measures list linkage, not successful recognition or company growth.

The two rows are different sets; subtraction does not establish gaps or relocation. List rows are not new companies or final recognition.

The municipal statistical bulletin and this 107-record reporting-jurisdiction archive have different scopes and are analysed separately.

How should a study distinguish validation requirements for discrete equipment and process systems when examining Dalian's equipment-manufacturing and petrochemical sectors?

In 2025, equipment-manufacturing value added in Dalian's above-designated-size industry rose 15.4% year on year. The notes define this category through eight industry divisions, including general equipment, specialised equipment, automobiles, and the combined railway and ship-related transport-equipment division. [1]

Petrochemical-industry value added rose 8.9% in the same year. The passage uses the communique's above-designated-size industrial scope: industrial legal entities with annual main-business revenue of at least RMB20 million. Value-added growth is calculated at constant prices. [1]

Interpreting the archive alongside the bulletin

An equipment study should verify standard parts, individual machines and complete systems separately, then identify the delivery levels represented in the archive. Equipment manufacturing combines different production activities. Its city growth rate cannot substitute for operating evidence on a machine-tool segment, ship-related components or an individual company. [1]

For petrochemical-related records, product suitability should be assessed through process use, material compatibility, operating conditions and test records. These are validation conditions. The communique does not establish that archived companies have entered local petrochemical customers' procurement or maintenance systems. [1]

The 2025 macro context for Liaoning uses a different denominator from this cohort.

Shared records with Magnetic Sensors Current Transformers Keyword Candidate Study: 3; records in this cohort but outside that set: 104. The intersection/union ratio is 2.4%, a measure of label overlap rather than business collaboration. Read comparison

Shared records with Precision Casting Investment Casting Keyword Candidate Study: 7; records in this cohort but outside that set: 100. The intersection/union ratio is 2.2%, a measure of label overlap rather than business collaboration. Read comparison

Stable-ID samples, not rankings; metrics use the full cohort.
