In recent years, the global supply chain system is being affected by huge chain reaction, thus, it is of great practical significance to study customer momentum. Based on the supply chain network data disclosed by Chinese A-share listed companies from 2011 to 2019, this paper uses edge betweenness centrality as a representative index of supplier-customer network centrality to explore the moderating effect of edge betweenness centrality on the impact of customer stock price changes on supplier stock price changes. It is found that the change of customer stock price has a significant positive correlation with the change of supplier stock price in the next month, and the higher supplier-customer edge betweenness centrality degree, the more significant the positive correlation. This conclusion is robust, and low supplier concentration will enhance the moderating effect of this indicator. Additionally, the new customer momentum factor can be further constructed by using the edge betweenness centrality. The research of this paper provides a new applicable situation for the transmission of customer momentum, helps to enrich the literature related to supply chain information management and realize the mining of Alpha in supply chain data.
