Digitalisation and financialisation constitute two major trends in the future economic development of China. They overlap and interpenetrate each other，fundamentally overturning the operational characteristics of the traditional industrial economy and bringing risks and uncertainties to economic and social development. The industrial taxation system based on the traditional economic model is becoming increasingly difficult to adapt to the digital and financial development，the tax subject，the basis for taxation and other elements are becoming increasingly difficult to define accurately，tax collection and administration is becoming increasingly difficult. There is an urgent need to use new concepts to empower the overall taxation reform. In the future，the focus should be on reducing uncertainty and creating a flexible taxation system，and redesigning the elements of the taxation system in five aspects：subjects，links，bases，points and collection and administration，so as to enhance the adaptability of taxation to the digital and financial development of the economy.
