Based on their positions within control relationships, listed companies can be categorized into parent companies, subsidiaries, associate companies, and joint ventures. The commonly referenced "listed company" encompasses not only the parent entity but also the entire enterprise group comprising its subsidiaries, associates, and joint ventures. The composition of listed companies and their affiliated entities undergoes annual variations.

  CnOpenData's Extended Data on Basic Information of A-share Listed Companies and Their Subsidiaries integrates comprehensive multidimensional information (1990–2024) on A-share listed companies and their subsidiaries, associates, and joint ventures. It comprises two core modules:

• Affiliated Entities List: Systematically extracted directory of affiliated companies from annual reports (including securities code, affiliate name, and relationship to the listed company);
• Extended Business Registration Information: Precise linkage of affiliated entities with industrial and commercial registration data (40+ fields such as enterprise name, unified social credit code, taxpayer identification number, industry classification, registered address) through a dual-matching approach (exact + fuzzy matching), forming a structured database covering detailed business fundamentals.

Data Uniqueness

• Exclusive Integration of "Affiliation Relationships + Business Panorama": Uniquely combines affiliation relationships disclosed in annual reports (e.g., subsidiary/associate roles) with business entity details (paid-in capital, operating period, industry classification), addressing the disconnect between "relationship networks" and "entity attributes" in academic and commercial analyses.
• Dual-Matching Mode Ensures Coverage: Simultaneously provides exact and fuzzy matching results, annotating matching confidence levels (marked fields), mitigating omissions caused by name changes in traditional databases.
• Granular Geographic and Industry Classification: Registered addresses refined to district/county level (province code to district code); industry classification spans a four-tier hierarchy from sector to subclass (sector code – subclass code), supporting regional economics and industrial chain research.

Data Application Value

• Academic Research: Construct parent-subsidiary control maps via securities code + affiliate names; analyze policy diffusion pathways to subsidiaries based on province + industry subclass, etc.
• Commercial Decision-Making: Screen investment targets using fields like paid-in capital (实缴资本) and operational risks (causes of deregistration/revocation); identify competitors' affiliated entity strategies via business scope + industry sector.
• Policy Evaluation: Track corporate survival rates using registration year + region codes to assess regional business environments.

CnOpenData's Extended Data on Basic Information of A-share Listed Companies and Their Subsidiaries is a structured database deeply integrating listed companies' affiliation relationships with fundamental business entity dimensions. With 34 years of historical coverage, dual-matching technology, and 40+ fields for granular analysis, this repository provides one-stop infrastructure support for academic research on corporate ecosystems, financial institution risk assessments, and governmental industrial policy formulation.
