Abstract:

Using China’s Shanghai and Shenzhen A-share listed firms from 2010 to 2018 as the research sample and taking the successive implementation of the Shanghai-Shenzhen-Hong Kong Stock Connect programs as exogenous shocks, this paper constructs a multi-phase DID model on the basis of PSM method to examine the impact of the stock market liberalization on the corporate tax avoidance. The results indicate that the stock market liberalization significantly reduces the tax avoidance behavior of eligible firms. The effect is mainly reflected in the firms with fewer analysts, higher deviation of analysts’ earnings forecast and lower degree of voluntary information disclosure. The mechanism test shows that an improvement in the information transparency and an increase in the audit quality are two important channels through which the stock market liberalization affects the tax avoidance. This paper reveals the governance effect of the stock market liberalization from the perspective of the tax avoidance, and provides empirical evidence for the follow-up formulation of China’s stock market liberalization policy.

Key words: Stock Market Liberalization, Tax Avoidance, Shanghai-Shenzhen-Hong Kong Stock Connect, Information Transparency, Audit Quality

摘要:

采用2010—2018年我国沪深A股上市公司为研究样本,以沪深港通交易制度的陆续实施为外生冲击,在PSM基础上构建多期DID模型检验资本市场开放对企业避税行为的影响。研究发现:资本市场开放显著抑制了企业避税行为;这种抑制作用主要表现在分析师跟踪人数较少、分析师盈余预测偏差较高以及自愿性信息披露程度较低的企业;信息透明度和审计质量的提升是资本市场开放抑制企业避税行为的主要机制。本研究从避税的视角揭示了资本市场开放所发挥的治理效应,为我国资本市场开放政策的后续制定提供了经验证据。
