Abstract: There are intricate supply and demand relationships between various market objects in the economic market, which in turn form an industrial organizations network. This paper uses the transaction data from the bank to present the inter-firm relationships in the city of Yiwu, and overcomes the limitation that the input-output method can only reflect the inter-industry connections. In addition, it also introduces the exponential random graph model to investigate the impact of the diverse social processes in the formation of inter-firm relationships and their role in shaping the industrial organizations network from a more microcosmic perspective. The results show that there is a strong tendency of reciprocity in the inter-firm relationships in Yiwu, and there are more two-way interactions than one-way trading. The firms in Yiwu are more likely to choose transaction objects through middleman, which means that transitivity plays an obviously positive role in the network, while popularity and activity mainly play a negative role, that is, firms are not willing to expand commercial channels. Compared with non-profit organizations, firms play more of the role of suppliers, and firms located in relatively affluent and less populated areas have higher export capabilities.

Key words: industrial organization network, inter-firm relationships, exponential random graph model (ERGM), endogenous structural effects, actor-relation effects
