Anti-tax Avoidance, Spillover Effect and International Tax Competition Data

In this paper, we add three kinds of anti-tax avoidance methods in ZMW tax competition model, namely “transfer pricing rules of neighboring countries”, “transfer pricing rule of domestic country” and “number of domestic tax treaties” to investigate the spillover effect of anti-tax avoidance system on enterprise income tax base and tax rate. We use the balanced panel data of 50 countries from 2000 to 2013 and system GMM method to test the theoretical propositions.We find that “transfer pricing rules of neighboring countries” and "number of domestic tax treaties" reduce the domestic tax base, but "domestic transfer pricing rule" have no significant effect on the tax base.The three kinds of anti-tax avoidance methods do not eliminate international tax competition behavior.With the improvement of anti-avoidance management the level of tax competition among countries will increase significantly, especially among developed countries.本文在ZMW税收竞争模型中引入三类反避税手段，即邻国转让定价规则、本国转让定价规则与本国税收协定数量，旨在考察反避税体系对企业所得税税基与税率的溢出效应。本文采用2000至2013年50个国家的平衡面板数据，结合系统广义矩估计（system GMM）方法对理论命题进行检验。研究结果表明，邻国转让定价规则与本国税收协定数量会缩减本国税基，而本国转让定价规则对税基无显著影响。上述三类反避税手段并未消除国际税收竞争行为；随着反避税管理水平的提升，各国间的税收竞争程度将显著加剧，这一现象在发达国家群体中尤为突出。
