Supply Chain Structure and Competitor Relationship

Abstract This chapter discusses recent relevant empirical research using the supply chain structure observed in the actual data, including shock propagation in the supply chain network, social capital, and supply chains, and cross-border supply chains. It also introduces some commonly used empirical methods and databases, and provides the corresponding financial theoretical basis for the conclusions of these studies. Finally, the chapter suggests a new angle to fully utilize the supply chain structure to identify the competitor relationship and the competition intensity. The chapter indicates that higher supply chain overlap increases the correlation of the competitors’ economic performance, suggesting that sharing supply chains reduce competition. This conclusion is helpful for entrepreneurs to better manage firm competitions.
