有社會責任的公司比較不會避稅嗎？－台灣上市公司實證

Abstract

本文旨在探討CSR對於企業避稅的影響。實證結果發現，沒有證據顯示CSR績效較好的公司比較不會進行避稅活動。額外分析顯示CSR各分類指標與企業避稅的關係，經濟指標與GAAPETRs (CashETRs)呈顯著負相關，法律指標與GAAPETRs呈顯著正相關，社會指標與GAAPETRs呈顯著負相關，環境指標則與CashETRs呈顯著正相關，資訊揭露指標與CashETRs則呈顯著負相關。實證結果也發現獨立董事在董事會的租稅管理策略之功能發揮上所扮演關鍵性角色，台灣上市公司獨立董事比率普遍偏低，建議應提高獨立董事比率，有助於降低企業避稅。

This study examines whether corporate social responsibility performance is associated with corporate tax avoidance in Taiwan stock market over the period 2007-2012. The empirical results provide no evidence that companies with good CSR are less likely to engage in tax aggressiveness. The results from our additional analysis show that economic category is negative associated with GAAPETRs (CashETRs), law category is positive associated with GAAPETRs, social category is negative associated with GAAPETRs, environment category is positive associated with tax avoidance CashETRs, Information disclosure category is negative associated with CashETRs. The empirical results of this study also revealed an important role of independent directors in taxation management strategies. The typically low ratio of independent directors to the board of directors of Taiwan’s listed companies should be increased in order to reduce corporate tax aggressiveness.
