公司長短期避稅行為決定因素──以台灣上市櫃公司為例 / The Determinants of Long-run and Short-run Corporate Tax Avoidance

紀琇芳 Unknown Date (has links)
為分析長期與短期公司避稅行為之決定因素以及相關產業效果,本文以實證 方法檢視租稅規避行為之決定因素,並以現金有效稅率及調整後財稅差異作避稅 指標,研究對象為 2002 年至 2012 年之台灣上市櫃公司,同時排除性質特殊之金融業以及臺灣存託憑證(TDR)。 首先,本文採固定效果模型進行短期避稅行為之分析,其實證結果顯示當企 業知名度較高、研發投資較多、負債資產比較高、投資損失較多及關係企業設立 在租稅天堂時,企業積極從事避稅行為的可能性較低。另一方面,結果顯示當企 業持有固定資產較多、投資利益較多、獲利較多及有前期淨營業損失時,企業積 極從事避稅行為的可能性較高。 其次,本文採普通最小平方法模型進行長期避稅行為之分析,其實證結果顯 示當企業長期知名度較高、負債較多、投資損失較多及獲利較多時,企業積極從 事長期避稅行為的可能性較低。另一方面,結果顯示企業長期固定資產較多、研 發投資較多及投資利益較多時,企業積極從事長期避稅行為的可能性較高。 最後,為觀察個別產業之避稅行為,本研究進行平均值差異數 T 檢定、長期 普通最小平方法回歸結果以及 F 檢定,結果顯示:半導體業、建材營造業等產業 積極從事避稅行為的可能性較高。另一方面,觀光事業、油電燃氣等產業積極從 事避稅行為的可能性較低。

避稅、租稅競爭與公共財提供 / Tax avoidance, tax competition and provision of public goods

謝馨儀, Hsieh, Hsin I Unknown Date (has links)
傳統探討利潤移轉效果的租稅競爭文獻中,忽略廠商租稅規避效果對公共財的影響。然而,在貿易自由化與國際化興盛的時代下,廠商對於國與國之間的租稅安排是複雜且不可避免,所以在探究租稅競爭時,租稅規避也是一項重要的考量因素。因此本文以Lai (2006) 一文為基礎,建構一個具有利潤移轉效果的國際租稅競爭模型,分別為Cournot數量競爭與Bertrand價格競爭,來探討廠商租稅規避效果對國際租稅競爭導致公共財提供量不足的影響問題。 本文章有幾點發現:Cournot 數量競爭下,避稅效果會強化稅基、稅收效果,和利潤移轉效果,加劇公共財提供數量不足的問題。而Bertrand價格競爭下,避稅效果同樣會使公共財提供量下降,但此模型下的利潤移轉效果對公共財影響為正向,使得公共財數量皆大於Cournot模型之下。此外,本文也探討眾多參數對政府最適決策的影響。 / The traditional literatures of tax competition, which include the rent shifting effect, ignore the impact of tax avoidance effect on public goods. However, the taxation arrangements between countries which firms face are complex and inevitable in this era of trade liberalization and internationalization. Therefore, when investigating tax competition, we should consider an important factor- tax avoidance. So, this paper is based on Lai (2006) to build an international tax competition model containing rent shifting effect. We will discuss the problem of insufficient public goods and how tax avoidance effect influence this question in Cournot competition and Bertrand competition. This conclusion shows that tax avoidance effect enhances tax-base effect, revenue effect and rent shifting effect in Cournot competition. In this condition, the issue of insufficient public goods will worsen. In Bertrand competition, tax avoidance effect will also make the quantity of public goods fall. But rent shifting effect in this model is so good for public goods that the quantity of public goods is larger than Cournot competition. Furthermore, this paper also uses software to test many parameters and finds the parameters how to influence government's optimal decision.
