Market access, supply chain resilience and enterprise innovation

The global supply chain has been experiencing frequent “chain break” events, raising concerns about supply chain resilience within the academic community. When innovating, enterprises require support for supply chain resilience when faced with the risk of a “chain break.” Current research primarily focuses on the impact of information technology or digital technology on enterprise supply chains, neglecting the influence of market accessibility on enterprise innovation performance through the supply chain system. By considering supply chain resilience as an influence path, this study assesses the impact of market accessibility on firms’ innovation performance. The results suggest that market accessibility significantly influences innovation performance, but its impact on innovation quality is less pronounced concerning the quantity of innovative output. The impact of market accessibility is partly due to market expansion beyond a firm's domestic boundaries. The mechanism analysis reveals that market accessibility improves supply chain resilience by optimizing efficiency and adaptability, fostering enterprise innovation performance. However, market accessibility undermines supply chain stability, enhancing innovation. Further analysis suggests that market accessibility has a stronger positive impact on the innovation performance of larger firms and their localities. Additionally, it mitigates the negative effects of geographical distance on firm innovation.
