Can securities supervision reduce corporate tax avoidance?

Area of Science:

• Accounting
• Financial Regulation
• Corporate Governance

Background:

• China's stock exchange comment letter system serves as a unique regulatory mechanism.
• Corporate tax avoidance is a significant concern for securities regulators and tax authorities.
• Understanding the effectiveness of regulatory interventions in curbing tax avoidance is crucial.

Purpose of the Study:

• To investigate the relationship between tax-related exchange comment letters and corporate tax avoidance behavior in China.
• To determine if tax-related comment letters influence subsequent corporate tax avoidance.
• To explore the moderating effects of comment letter characteristics and firm-specific factors (political connection, state ownership) on this relationship.

Main Methods:

• Analysis of Chinese stock exchange comment letters and corporate financial data.
• Empirical examination of the correlation between receiving tax-related comment letters and the level of corporate tax avoidance.
• Difference-in-differences approach comparing firms receiving tax-related versus non-tax-related comment letters.
• Sub-sample analysis based on political connection, state ownership, and regional tax administration strength.

Main Results:

• Firms engaging in more aggressive tax avoidance are more likely to receive tax-related exchange comment letters.
• Receiving a tax-related comment letter leads to a reduction in subsequent corporate tax avoidance compared to non-tax-related letters.
• The inhibitory effect is amplified by the number of questions and detail within the comment letter.
• Tax-related comment letters effectively curb tax avoidance in state-owned enterprises and politically connected private firms.
• The monitoring effect is stronger in regions with weaker tax administration.

Conclusions:

• The stock exchange comment letter system, particularly its tax-related component, acts as an effective tool in regulating corporate tax avoidance.
• The system's efficacy is enhanced by specific communication characteristics and is particularly potent for state-linked entities and in areas with weaker fiscal oversight.
• Comment letters can serve as a supplementary mechanism to strengthen overall tax administration and compliance.
