The dramatic development of technologies，mobile Internet，big data，cloud computing，artificial intelligence，as well as block chain and their depth and comprehensive application in the financial system，makes FinTech system gradually enter the FinTech 2.0 stage. Compared to Internet finance，FinTech，with essential cross-border implementation，disintermediation effect，decentralization and self-learning，has greater financial resources integration capability and ecosystem construction function and more significant impacts on the financial system.

Based on the comprehensive understand of the FinTech，it is vital to establish a long-term regulation framework，combining the reconstruction of financial regulatory structure，appropriate supervision Regtech，with China’s style Sandbox mechanism，to firmly hold the bottom line of systemic risks and to keep the FinTech system be stable and sustainable.
