摘要：

We use the exponential random graph models to understand the network structure and its generative process for the Japanese bipartite network of banks and firms. One of the well-known and simple models of the exponential random graph is the Bernoulli model which shows that the links in the bank-firm network are not independent from each other. Another popular exponential random graph model, the two-star model, indicates that the bank-firms are in a state where the macroscopic variables of the system can show large fluctuations. Moreover, the presence of high fluctuations reflects a fragile nature of the bank-firm network.
