摘要：
With the rapid development of the modern financial industry, the complexity of the network formed by multiple financial entities has continued to deepen, and the probability of systemic risk has increased significantly. The use of complex network theory to explore the network topology and evolution process of financial markets plays an important role in the measurement, contagion and prevention of systemic risk. In this review, the connotation of systemic risk is clarified firstly along with their causes and characteristics, common indicators and complex network models are reviewed, and the important impact of systemic risk in financial networks is pointed out. Based on the correlation between financial institutions, the algorithm for building the network model and the measurement method of systemic risk are discussed, and their characteristics are evaluated, along with their advantages, limitations and applications. Then, the contagion effect of systemic risk under the network structure are also analyzed. Finally, based on the perspective of complex networks, challenges in systemic risk problems are concluded to throw some light on the future research. © 2022 South China University of Technology.
