The innovation and technological innovation are economic concepts in theoretical study. In consideration of specific practices and contexts，innovation，technological innovation and scientific and technological innovation have both connections and differences. The narrowly defined financial innovation mainly refers to financial product innovation and instrument innovation. From an innovation perspective，financial innovation is a process that adapts to the changes in external technologies and regulatory environment and creates a more efficient capital operation and management system involving the revolutions in products，service，tools，markets，organizations，technologies，management and supervision. Financial innovation and scientific and technological innovation interact with each other where the latter provides technological support for the former and especially the scientific technological innovation represented by modern information communication and Internet technology is a significant driving force to promote the financial innovation.

Nowadays the financial technology attracts a massive amount of investment and the traditionalfinancial institutions and emerging Internet enterprises to be involved，which has aroused great concern among financial strategy makers across countries. The study shows that from the perspective of innovation theory，there are different forms of financial technological innovation in different periods. The current financial technology is essentially the financial technology innovation formed in the financial service industry with the application of the information technology innovation represented by the new generation of information and communication and Internet technology，which is still a model of the combination of scientific and technological innovation and financial innovation.
