Abstract:    Open sharing of data resources is the key to release the innovation vitality of digital economy. Assessing the innovative impact of government data opening holds significant implications for fostering the advancing high-quality economic and social growth. Leveraging the successively launched local government data opening platforms, this paper employed a staggered difference-in-difference model to examine the effect of government data opening on enterprise innovation. The research results indicated that government data opening significantly elevates the level of enterprise innovation. The mechanism analysis revealed that government data opening, by leveraging talent and capital elements, propels enterprise digital transformation, thereby stimulating enterprise innovation. Furthermore, the innovation-promoting effect of government data opening is more pronounced in enterprises with higher levels of government data opening, stronger intellectual property rights protection, high-tech orientation, and increased investments in information technology. Further research found that, government data opening can foster both open innovation and digital technology innovation while enhancing innovation efficiency and quality. This study has extended the theoretical research on enterprise innovation from the perspective of data resources, thus providing significant policy recommendations for expediting the construction of digital government, enhancing the management of government data resource systems, and deepening the implementation of innovation-driven development strategies.
