Abstract: To prevent and control the financial risks effectively, it is necessary to find out the ultimate cause. At present, the financial risks existing in our country are virtually the institutional risk, and the system of property rights are, the source of forming institutional risks. We should deepen property rights reform and establish our market financial system. At the same time, we should also actively use the international advanced experience for reference and pursue the new financial system that is in favor of the prevention of financial risks, but the applicability of financial institutions should be paid much attention to lest new financial rishs should occur.
