Empirical Study On Business Credit Based On Supply Chain Concentration

Based on panel data of China's A-share listed companies from 2014 to 2023, this paper empirically investigates the impact of supply chain concentration on corporate commercial credit and explores its underlying mechanism. The results reveal that a higher degree of supply chain concentration significantly inhibits the level of commercial credit extended by enterprises. This inhibitory effect is more pronounced among mature firms, state-owned enterprises, downstream firms within the supply chain, and firms located in economically underdeveloped regions. These findings suggest that excessive dependence on a limited number of supply chain partners may weaken firms' bargaining power and financing flexibility, thereby constraining their credit provision behavior. This study not only enriches the literature on the interplay between supply chain structure and firm-level credit decisions but also provides theoretical support and practical implications for enhancing corporate credit management, optimizing supply chain relationships, and mitigating debt risks in complex market environments.
