Abstract: Along with China’s economy enters the new normality, the development of the financial industry breaks away from the real into the virtual, the financial size is over expanded and exceeds the real economy scale, the illegal financial activities run wild which drifts away from the regulatory system in the name of financial innovation, and the financial innovations are in excess of the demand of the real economy development, which brings uncertainties to the stability of the financial markets. Seeing from the financial sources, the core category and development process of finance are closely related to the real economy. We should closely integrate the development space of financial services with the improvement of the development ability of the real economy, and at the same time adhere to the three boundaries of financial innovations, i.e., the law, the regulations and the risk, only in this way can we ensure the vitality and the bearing capacity of the financial development.
