This paper tries to have some innovations in the following aspects:(1) the main cause of our tax revenue depending mainly on turnover tax is short of innovation in system;(2) its innovation in system to impel the rising of income tax in developed counties, which is a good example for us to learn from in the optimization of our tax structure ;(3) the main function of turnover and income tax should be separated according to their characters;(4) the reforms in turnover and income tax should be taken simultaneously, congenially and complementally, although the former will be more progressive while the later more abrupt;(5) the essential function of tax is to raise revenue, but its fair-promoting effect is much more obvious in disbursing than in collecting.
