China's Chain Leader Policy: Firm-Level Panel Data on A-Share Listed Companies, 2011-2023

An unbalanced panel dataset contains 14,987 firm-year observations from 3,703 unique A-share listed firms in China, spanning from 2011 to 2023. The data was compiled by Wenjing Li to study the effects of the Chain Leader Policy introduced in 2017, excluding financial sector firms and those in financial distress. The dataset was last updated on the figshare platform in April 2026.

Use Cases

• Analyzing the impact of the Chain Leader Policy on firm-level outcomes based on the pre- and post-policy observation period.
• Studying corporate collaboration and innovation patterns among Chinese A-share listed firms.
• Conducting econometric panel data analysis using the unbalanced firm-year structure described.
• Investigating sectoral differences in policy response, excluding the financial industry as noted.

Strengths

• Contains 14,987 firm-year observations, providing a substantial sample for analysis.
• Covers a 13-year time range from 2011 to 2023, including six years of pre-policy data.
• Data is cleaned with winsorization at the 1st and 99th percentiles to mitigate outlier influence.
• Explicitly excludes ST/*ST firms to avoid financial distress bias.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is an unbalanced panel, which may complicate some longitudinal analyses.
