Since information systems are widely used in the management of financial institutions, financial institutions generate a large amount of data in their daily use. However, a large amount of data has not been effectively used. In daily management, financial managers can receive surface information through potential techniques such as simple statistics, sorting, and inspection. With the rapid development of mobile communications and the popularization of smart mobile devices, the number of mobile services has increased sharply, and mobile terminals have become resource-constrained devices. Traditional cloud computing can no longer meet the growing business needs. In order to improve the quality of service for users, mobile edge computing technology has become one of the key technologies of the fifth-generation mobile communication system. It reduces the burden on the core network and provides effective solutions to improve user experience. The financial service industry is an industry that produces services and provides intangible monetary and financial services. The financial service industry is an important part of economic growth. Its development trend and development status are directly related to the process of national economic development. Effective financing and investment work can bring economic benefits to state-owned enterprises, but there are certain financial risks in the process of financing and investment activities. In order to ensure the steady development of enterprises, the financial management department should correctly understand the types of financial risks in the investment and financing links and take targeted prevention and control measures.
