Statistical analysis shows that China’s unified Free Trade Area tax policy is lack of advantage than the major trading partner countries and competitive Free Trade Areas. All over the country with fiscal policy instead of tax policy will attract the agglomeration of production factors，which will bring the inefficient use of financial funds.
