Matched City-Firm Data on Environmental Rhetoric-Action Divergence in China, 2008-2015

Supplementary file 1 from the study 'Words vs. wallets: environmental rhetoric–action mismatches and firm carbon intensity in the energy transition' by Xinyu Wei, last updated on 2026-04-21. The dataset contains matched city–firm data from China for the period 2008–2015, used to examine the impact of local governments' environmental rhetoric-action divergence on firms' carbon emission intensity. The paper employs a two-way fixed effects model and finds a significant positive effect, with mechanism analysis exploring channels like innovation capacity and regulatory intensity.

Use Cases

• Analyzing the relationship between local government policy rhetoric and firm-level carbon emissions based on the matched city-firm data.
• Investigating the channels (e.g., innovation capacity, investment attraction) through which policy divergence affects corporate behavior as described in the mechanism analysis.
• Conducting heterogeneity analysis on firm types (e.g., state-owned vs. foreign-invested) as indicated in the results.
• Estimating the abatement gains and fiscal costs associated with reducing the rhetoric-action gap discussed in the paper.

Strengths

• Data covers a defined 8-year time range (2008–2015) for China.
• Analysis is based on a specific statistical model (two-way fixed effects) and reports a quantified effect size (3.4% increase in carbon intensity per one-standard-deviation gap).
• The dataset is associated with a detailed academic study that includes mechanism and heterogeneity analysis.
• Available under a permissive CC-BY-4.0 license.

Limitations

• The dataset is very small (18.7 KB), suggesting it is likely a supplementary document (e.g., a list of variables, summary statistics) rather than the primary research data.
• Row count and column-level documentation are unknown, limiting assessment of the data's structure and scale.
• The description is a research paper abstract; the actual data file's content and format require manual inspection after download.
