Abstract

Using difference-in-differences (DID) estimation with a unique micro dataset, we find that maritime officers issue more traffic citations during periods of fiscal stress, disproportionately targeting non-local firms in line with the classic tax-exporting behavior. This regulatory bias is driven by local protectionism and enforcement discretion. The bias is stronger in regions with greater local protectionist incentives, meanwhile non-local firms are more frequently penalized under authoritative national laws rather than local regulations, and face a significant increase in average fines. Furthermore, the bias is weaker for firms from neighboring provinces, those from regions with stronger cultural ties, or those in operating cites with stronger market-supporting institutions. The bias constrains the free flow of production factors, reducing freight distance and turnover, and may lead to long-term economic and social welfare losses.
