Based on their positions in control and controlled relationships, listed companies can be categorized into parent companies, subsidiaries, equity affiliates, and joint ventures. The commonly referred "listed companies" encompass not only the parent company but also the entire enterprise group composed of subsidiaries, equity affiliates, and joint ventures. The composition of listed companies and their affiliated subsidiaries undergoes changes annually.
The CnOpenData Extended Basic Information Dataset for A-Share Listed Companies and Their Subsidiaries integrates comprehensive multidimensional information on A-share listed companies and their subsidiaries, equity affiliates, and joint ventures, comprising two core modules:
- List of Affiliated Enterprises: Systematically extracted from annual reports of listed companies, this directory includes affiliated company names (with securities codes, affiliated company names, and relationships with the listed company).
- Extended Business Registration Information: Utilizing a dual-matching approach (exact + fuzzy matching), this module precisely links affiliated companies with business registration data (40+ fields including enterprise name, unified social credit code, taxpayer identification number, industry information, registered address) to form a structured database covering detailed business fundamentals.
Data Uniqueness
- Exclusive Integration of "Relationship Network + Business Panorama": Uniquely combines relationship disclosures from annual reports (e.g., roles as subsidiaries/equity affiliates) with business entity details (paid-up capital, operating period, industry classification), addressing the academic and commercial pain point of fragmented "relationship networks" and "entity attributes".
- Dual-Mode Matching Ensures Coverage: Provides both exact and fuzzy matching results, annotating matching reliability (marked fields), avoiding omissions caused by name changes in traditional databases.
- Granular Geographic and Industry Classification: Registered addresses are refined to district/county level (province code to district/county code), while industry classifications span four levels from sector to subclass (sector code – subclass code), supporting regional economic and industrial chain research.
Data Application Value
- Academic Research: Constructs parent-subsidiary control maps via securities codes + affiliated company names; analyzes policy diffusion paths to subsidiaries based on province + industry subclasses.
- Commercial Decision-Making: Screens investment targets using paid-up capital(实缴资本) and operational risk (reasons for deregistration/revocation); identifies competitors' affiliate layouts through business scope(经营范围) + industry sectors.
- Policy Evaluation: Tracks enterprise survival rates via registration year + region codes to evaluate regional business environments.
The CnOpenData Extended Basic Information Dataset for A-Share Listed Companies and Their Subsidiaries is a structured database that deeply integrates relationship networks and fundamental business entity dimensions. With 34-year historical coverage, dual-matching technology, and 40+ fields for granular analysis, this repository provides one-stop infrastructure support for academic research on corporate ecological networks, financial institutions' risk assessments, and governmental industrial policy formulation.
