国际税制竞争力对对外直接投资的影响——基于边际有效税率的研究

The Impact of International Tax System Competitiveness on Outward Foreign Direct Investment ——Research Based on the Marginal Effective Tax Rate

开放经济中,政府始终把提高国家竞争力作为重要的战略目标。税收是国家宏观经济政策运用的重要方式,如何有效提高国际税制竞争力就成了我们十分关心的问题。基于OECD边际有效税率模型测算出的边际有效税率作为国际税制竞争力指标,检验其对中国对外直接投资决策的影响。研究发现:较低的东道国边际有效税率有利于我国FDI的流入,在边际有效税率的测算过程中,企业所得税是影响边际有效税率的重要税收参数,为提高我国税制竞争力,建议从促进对外投资与吸引高质量外商直接投资两个角度来完善税收制度。

In the open economy,the government always takes improving national competitiveness as an important strategic goal. Tax policy as an important method of national macroeconomic policy, how to effectively participate in the international tax competition and optimize the tax system has become a matter of great concern to us. Based on the marginal effective tax rate model of OECD, this paper uses the marginal effective tax rate as an indicator of the competitiveness of the international tax system to test its impact on China's OFDI decision-making. The study finds that the lower marginal effective tax rate of the host country is beneficial to the inflow of OFDI in China. In the process of EMTR calculating, corporate income tax is an important parameter. In order to improve our tax system competitiveness, it is necessary to consider improving tax system from two aspects: promoting outward foreign investment and attracting high-quality foreign direct investment.
