"两税合一"并不会影响外资的流入

内外资企业所得税制的合并迟迟难以实现的主要原因是，主管部门担心合并后税负提高影响了外国直接投资进入的规模和速度，笔者认为大可不必为此担心。主要原因有三：第一，税收政策在一国的投资环境中只能起到部分激励作用，并非决定因素；第二，由于我国超过70％的外资来源于与我国尚未缔结避免双重征税协定或虽有协定但并不包括饶让条款的国家和地区，因此税收优惠政策并不是大多数外商投资者关注的重心；第三，对中小外国资本来说，税收政策的调整可能会有一些影响，但从提高效率的角度来看，这部分外资的减少反而会优化我国的外资结构，提高外资的使用效率。

The Incorporation of Two Set of Corporation Income Tax System doesn't Work on the Inflow of FDI

Some competent authorities are afraid that the incorporation of two set of corporation income tax system will work on the inflow of FDI,which put off the progress of the incorporation of two set of corporation income tax system.In fact,we shouldn't worry about it.The following three reasons can give you the answer.The first reason is that tax policy is only one minor motivational factor,not leading factor.The second is that in china over 70% of FDI came from some countries and areas without concluding an agreement with china on evading double taxation,or from ones entering into an agreement with china but without tax sparing clauses,so tax preference policy is not the focus of attention for the majority of FDI.The third is the adjustment of tax policy can work on the small and medium FDI,but in terms of efficiency,the induced FDI can instead optimize China's FDI structure and advance the availability factor of FDI.
