日本银行和企业二部网络的指数随机图模型

Exponential random graph models for the Japanese bipartite network of banks and firms

Abhijit Chakraborty, Hazem Krichene, Hiroyasu Inoue, Yoshi Fujiwara

摘要:

我们使用指数随机图模型来理解日本银行和企业的二分网络的网络结构及其生成过程。指数随机图的一个著名而简单的模型是伯努利模型,该模型表明银行-企业网络中的链接不是相互独立的。另一个流行的指数随机图模型,双星模型,表明银行-企业处于一个状态,系统的宏观变量可以显示出大的波动。此外,高波动的存在反映了银行-企业网络的脆弱性。

英文摘要:

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 model of exponential random graph is the Bernoulli model which shows 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 macroscopic variables of the system can show large fluctuations. Moreover, the presence of high fluctuations reflect a fragile nature of the bank-firm network.
