Chinese Firm-Level Air Pollution Data Linked to Carbon Trading Pilots, 1998-2014

A firm-level panel dataset constructed by matching the China Industrial Enterprise Database with the China Industrial Enterprise Pollution Database for the years 1998 to 2014. The data is linked to city-level information on China's carbon emissions trading system pilot implementation. The dataset was created by Mengxue Ji and published on figshare under a CC-BY-4.0 license.

Use Cases

• Estimate the effect of carbon trading policies on firm-level air pollutant emissions based on the staggered difference-in-differences design described.
• Analyze heterogeneity in policy effects based on firm size, region, debt ratio, and industry pollution level as mentioned in the description.
• Investigate the mechanism of technological innovation in reducing air pollution, as suggested by the study's findings.
• Conduct robustness checks for policy analysis, such as PSM-DID and placebo tests, using the linked firm and pollution data.

Strengths

• Data spans 17 years (1998-2014), providing a longitudinal panel for analysis.
• Links firm-level operational data with pollution emissions data and city-level policy implementation.
• Study reports specific average effect sizes (e.g., 11.02% reduction) and pollutant-specific reductions (e.g., -17.93% for sulfur dioxide).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The primary file is a 61.4 KB DOCX document, suggesting the dataset itself may be small or summarized rather than the raw underlying data.
