The tax incentives and corporate cash holdings: Evidence from a quasi-natural experiment of an accelerated depreciation tax policy for fixed assets

Based on a quasi-natural experiment of an accelerated depreciation tax policy (ADP) for fixed assets in China, we examine the impact of the ADP on corporate cash holdings. Using a multiperiod difference-in-differences model with a sample of Chinese A-share listed firms from 2008 to 2020, we document that firms subject to the ADP exhibit lower cash holdings compared to firms not affected by the policy. The effect is more pronounced for young firms, profitable firms, and firms with less R&D investment. According to our mechanism analysis, the ADP mitigates a firm's financing constraints and financialization and therefore, a firm does not need as much as cash holdings as they did before the implementation of the ADP. The mechanism test results suggest that the ADP lowers the precautionary and speculative demand for cash. The analysis of economic consequences shows that the reduction of cash holdings significantly enhances firm value. Our research results suggest that the ADP is a good policy for firms.
