Since the knowledge of tax-planning strategies and experience in implementing tax-planning strategies can be shared among firms via their network ties, especially through board interlocks, following Brown and Drake (2014), this study evinces that a firm’s tax avoidance behavior is related to its directorate ties to low-tax firms. Furthermore, this paper reveals that the influence of board interlocks on tax avoidance depends on certain characteristics of the firm’s ties, such as ties formed by executive directors, ties to low-tax firms engaging the same auditor, and ties to the firm’s low-tax family members. The empirical results of this study not only add evidence on network ties to the accounting literature but also can help explain part of the observed variation in corporate tax avoidance. 【 Keywords 】 board interlocks, tax avoidance 摘 要 根據知識擴散理論，企業的網絡連結可使其學習到其他公司的經驗，且隱晦複雜的新 知識透過連結所產生的擴散效益更高。有鑒於租稅規劃策略及經驗可經由企業的網絡 連結，尤其是董事連結來分享予其他公司，因此本文沿續 Brown and Drake (2014) 之研 究，實證結果顯示當企業與低稅負公司間存有董事連結時，其避稅行為亦會較高。此 外，研究結果亦發現董事連結對企業避稅之影響尚取決於某些連結之特性，例如經由 執行董事而產生董事連結、與連結之低稅負公司雇用同一個查核會計師、以及與連結 的低稅負公司屬同一個家族企業等，皆可使連結後之知識擴散效果增強。本文結果不 僅對文獻中關於網絡連結之應用上有所貢獻，實證結果亦可用於額外解釋各企業避稅 行為間的差異。 【關鍵字】 董事連結、企業避稅 Mei-Juh Huang , Department of Accounting, Fu Jen Catholic University 黃美祝 / 輔仁大學會計系 Received 2016/7, Final revision received 2017/9 NTU Management Review Vol. 29 No. 2 Aug. 2019, 201-232
