Abstract: The development of science and technology finance is an urgent need to achieve high-quality economic development. Science and technology finance promotes the transformation of science and technology innovation into real productivity through the allocation of resources and other functions, but its self-recycling makes fintech innovation a powerful weapon of capital idling, and capital "crazy disease" aggravates the tendency of capital "from real to fictitious", which may form a financial crisis. Since the Industrial Revolution, the asset bubble has been accompanied by the cycle of scientific and technological innovation, and the main reason is that virtual capital deviates from industrial capital. After the collapse of Bretton Woods System, virtual capital has become the core of capitalist production relations. China's strong macro-control policy has helped to calm financial volatility, and it is undergoing a triple transformation, so it should pay attention to balancing the three pairs of financial technology innovation and financial risk prevention.
