Abstract Taking the launch of government data platforms as a quasi-natural experiment, this paper examines A-share listed firms from 2010 to 2023 and employs a difference-in-differences model to test the economic consequences of open public data. It further explores how open public data affects corporate supply-chain resilience through two mechanisms: facilitating firms' utilization of data as a production input and enhancing their risk-taking levels. The results show that public data openness has a significant promoting effect on enterprise supply chain resilience, and this conclusion remains valid after a series of robustness tests. Mechanism analysis indicates that public data openness enhances the resilience of enterprise supply chains through a dual path of promoting the utilization of data elements and improving risk-taking levels. Further heterogeneity analysis reveals that the positive effect of open public data on corporate supply-chain resilience is stronger for firms with a lower degree of digital transformation or for non-high-tech firms, indicating that open public data helps bridge the “ digital divide ”. The effect is also more pronounced when firms are located in regions of higher administrative rank. The research conclusion expands the value creation effect of public data openness, providing empirical evidence and decision-making reference for continuously promoting public data openness to enhance the resilience of enterprise supply chains.
