Basic Information Data of A-Share Listed Companies and Their Subsidiaries

Based on their positions within control and controlled relationships, listed companies can be categorized into parent companies, subsidiaries, associates, and joint ventures. The commonly referred listed companies encompass not only the parent company itself but also the entire enterprise group formed by its subsidiaries, associates, and joint ventures. Annually, both listed companies and their affiliated subsidiaries undergo certain changes.

CnOpenData's Extended Basic Information Data of A-Share Listed Companies and Their Subsidiaries integrates comprehensive information across multiple dimensions for A-share listed companies and their subsidiaries, associates, and joint ventures. It comprises two core modules:

Affiliated Companies List: Systematically extracted list of affiliated companies from listed companies' annual reports (including stock codes, affiliated company names, and their relationships with the listed company);

Extended Business Registration Information: Through a dual-matching approach of exact matching + fuzzy matching, this module precisely connects affiliated companies with business registration data (40+ fields including enterprise name, social credit code, taxpayer identification number, industry information, registered address, etc.), forming a structured database covering detailed business fundamentals.

Data Uniqueness

Unique Integration of "Affiliation Relationships + Business Panorama": Exclusively combines the affiliation relationships disclosed in listed companies' annual reports (e.g., roles as subsidiaries/associates) with details of business entities (paid-up capital, business term, industry classification, etc.), addressing the pain point of the disconnect between "relationship networks" and "entity attributes" in academic and commercial analyses.

Dual-Mode Matching Ensures Coverage: Provides both exact and fuzzy matching results simultaneously, annotating matching reliability (marked fields), thereby avoiding omissions caused by name changes in traditional databases.

Granular Geographical and Industry Classification: Registered addresses are detailed down to the district/county level (province codes down to district/county codes), and industry classifications span 4 levels from broad categories → sub-categories (category codes – subclass codes), supporting regional economic and industrial chain research.

Data Application Value

Academic Research: Constructs parent-subsidiary control maps through stock codes + affiliated company names; analyzes policy diffusion paths to subsidiaries based on provinces + industry subcategories.

Commercial Decision-Making: Screens investment targets using fields such as paid-up capital (实缴资本) and operational risks (reasons for deregistration/revocation); identifies competitor affiliate layouts through business scope + broad industry categories.

Policy Evaluation: Tracks enterprise survival rates using registration year + region codes to evaluate regional business environments.

CnOpenData's Extended Basic Information Data of A-Share Listed Companies and Their Subsidiaries is a structured database deeply integrating affiliation relationships of listed companies with fundamental dimensions of business entities. Leveraging 34 years of historical coverage, dual-matching technology, and the capability for in-depth analysis across 40+ fields, this database provides one-stop infrastructure support for academia researching corporate ecological networks, financial institutions conducting risk assessments, and government departments formulating industrial policies.
