Sustainable Supply Chain and Carbon Trading: A Resilience Synergy

ABSTRACT Supply chain disruptions have become increasingly frequent due to extreme weather conditions and worsening eco‐pollution, posing challenges to sustainable development. As tools to enhance supply chain resilience in this uncertain environment, the sustainable supply chain and carbon trading policies are receiving heightened attention. This study, therefore, aimed to examine how they synergistically affect supply chain resilience among A‐share listed firms in China. Based on a multi‐period difference‐in‐differences analysis of firm‐level data from 2009 to 2023, the study confirms the positive synergistic impact of the dual policies on supply chain resilience. Firms that adopted the carbon trading policy before the sustainable supply chain policy experienced the most significant improvement in resilience. These effects were found to be mediated by the mechanisms of green innovation and supply chain efficiency. In terms of heterogeneity, the synergistic influence of the dual policies on supply chain resilience is more pronounced in firms that are mature, privately owned, and in the manufacturing sector. These findings offer critical information to guide policymakers in strengthening supply chain resilience.
