The Journal of Supply Chain Management's 2022 emerging discourse incubator looks to encourage scholars from different disciplines to develop and test new theories to advance our understanding about why and how firms should manage supply network resources for deploying competitive actions and gaining competitive advantage. To start that discourse, this issue offers three invited papers. In "Broadening our understanding of interfirm rivalry: A call for research on how supply networks shape competitive behavior and performance," Christian Hofer, Jordan Barker, Laura d'Oria, and Jon Johnson discuss the criticality of the supply network to a focal firm's capability in engaging competitive behaviors and the effectiveness of their rivalrous activities, which together affect the firm's competitive advantage. Michael Howe and Yao Jin explore the relational multiplexity theoretical framework in "It's Nothing Personal, or is it? Exploring How Relational Multiplexity in the Supply Chain Can Enhance Competitive Behavior." In "A theoretical model on how firms can leverage their supply chain strategy through political actions," Abhay Grover and Martin Dresner use the structure-conductperformance and competitive dynamics perspectives to theorize about the relationship between political strategies, supply chain risk management strategy, and firm competitive advantage. These invited papers provide a solid foundation to further a discourse that explains how and why changes in supply chain networks can enable firms to rapidly introduce competitive actions such as new product innovations to remain competitive in their respective industries.
