How Does Tax Avoidance Affect a Firm's Investment Inefficiency in Taiwan's Semiconductor Industry?

This study examines an important issue regarding how tax avoidance affects a firm's investment inefficiency in Taiwan's semiconductor industry. In addition, the dynamic effect of a firm's investment inefficiency and spillover effect of investment inefficiency from competitors are also explored. This study adopts 44 listed firms from 2013 to 2021 and constructs the "competitor-dependence matrix" to replace the "spatial-dependence matrix" in the dynamic spatial autoregressive model. According to the difference generalized method of moments estimation, the primary finding of this study is that the tax avoidance has a statistically and significantly positive effect on a firm's investment inefficiency while it is overinvestment, but a negative effect while it is underinvestment. Moreover, the dynamic effect is statistically insignificant, but the spillover effect is statistically and significantly negative.
