Research interests
Fiscal shocks and municipal non-tax revenue
A study of how the Business Tax-to-VAT reform affected the expansion of non-tax revenue in Chinese cities, and the role sub-provincial fiscal self-sufficiency plays in buffering that effect.
- Data. 270 prefecture-level cities, 2011–2020; balanced panel with sample screening and preprocessing.
- Identification. Intensity difference-in-differences on the fiscal shock from the Business Tax-to-VAT reform, with city and province-year interactive fixed effects, isolating confounding from the VAT 50/50 split.
- Dynamic effects. Parallel-trends and event-study analysis to verify the precondition of the DID identification, followed by placebo permutation tests to rule out spurious effects from random assignment.
- Benchmark regression. Main effect of the reform on non-tax revenue expansion, and the buffering moderation of sub-provincial fiscal self-sufficiency.
- Heterogeneity. Cities grouped by sub-provincial fiscal self-sufficiency, comparing transmission under high- and low-self-sufficiency regimes.
- Transmission mechanisms. Tax-base shrinkage measured by tax density, and the pure-tax fiscal gap, as institutional transmission channels.
- Robustness. Outcome replacement, sample adjustment, confounder control, and alternative clustering and standard-error specifications.
The work concludes with recommendations for sub-provincial fiscal system reform and non-tax revenue governance.
