Abstract: Facing the increasingly complex international and domestic environment, maintaining strong fiscal resilience is an inevitable requirement for deepening finance as the foundation and important pillar of national governance. In the context of the digital economy, exploring the impact of public data opening on local fiscal resilience is of great significance for promoting the modernization of national governance systems and capabilities, and coordinating national stability and development. Using the launch of public data platforms as a quasi-natural experiment, this study selects panel data of prefecture-level cities from 2007 to 2023 to explore the impact and mechanism of public data opening on local fiscal resilience. The results show that public data opening significantly improves local fiscal resilience, and this promoting effect is more prominent in regions with lower dependence on transfer payments, higher economic policy uncertainty, higher government digital attention, and higher initial level of digital infrastructure. Mechanism tests indicate that public data opening significantly enhances local fiscal resilience through the incentive effect of technological innovation and the improvement effect of government governance efficiency. Therefore, it is suggested to continuously promote public data opening and improve the data element sharing mechanism; implement differentiated policies according to local conditions to fully release the dividends of public data elements; standardize the data element market and accelerate the construction of digital government.
