英文摘要：
In this study, we investigate the evolution of Chinese guarantee networks from the angle of sub-patterns. First, we find that the mutual, 2-out-stars and triangle sub-patterns are motifs in 2- and 3-node subgraphs. Considering the heterogeneous financial characteristics of nodes, we find that small firms tend to form a mutual guarantee relationship and large firms are likely to be the guarantors in 2-out-stars sub-patterns.

中文摘要：
在本研究中，我们从子模式的角度考察了中国担保网络的演变。首先，我们发现在2节点子图和3节点子图中，相互子图、2-out-star子图和三角形子图是基序。考虑到节点的异质性财务特征，我们发现小企业倾向于形成相互担保关系，而大企业很可能是二星模式下的担保人。
