The aim of this study is to explore the social network structure of bidders by observing the bidding timing, bidding price and related interactions among bidders. Data are collected from the community of "bidding shoes!" of Facebook. Totally, 300 bidding transaction records are collected. The results of the study show that bidders have preferred timings for bids, and they will vary depending on the price group of the product. Furthermore, in the interactive state of bidders, the study is divided into simple bidding structure, sequential bidding structure, multi-bid structure, complex multi-bid structure and intervention bidding structure according to their characteristics. The most involved social network scale is the intervention bidding structure. And a further study is then explored to identify characteristics of the intervention bidding structure. Results are expected as a reference for sellers and community managers to find appropriate auction opportunities and prices.
