Digital innovation is the core driving force for the high-quality development of digital economy, and how to effectively link the government, market and society to realize the "increase in quantity and quality" of digital innovation is an important issue to be solved. From the perspective of the new structural economic theory and based on the institutional framework of "government-market-society", this study, taking 280 prefecture-level cities in China from 2010 to 2021 as case studies, adopted the dynamic QCA methods to investigate the linkage effect and path selection of digital innovation driven by multiple factors in a spatial and temporal dimension. The study showed that: First, no single institutional factor of government, market and society constitutes a necessary condition to drive the "incremental improvement" of digital innovation. Second, the combination effect of multiple factors to form the "incremental quality" of digital innovation has the characteristics of "different paths to the same destination" and "multiple concurrency". There are three typical combinations of government-led, government-market-led and government-market-society synergistic promotion systems that can realize "incremental" digital innovation. And there are two organizational ways to achieve "quality improvement" in digital innovation: government-society-driven and government-market-society synergistic promotion. Third, the spatial context analysis based on the grouping pattern showed that there are obvious regional differences in urban digital innovation paths, with the government in the eastern region playing a leading role in the "incremental improvement" of digital innovation, while the central and western regions rely mainly on the market to cultivate it. Fourth, in a comparative analysis over multiple time periods, two types of institutional configurations, "government-led" and "government-market-society synergistic", are found to be among the "dominant trajectories" driving digital innovation, which consistently and steadily emerged. The study has both broadened the research horizon of digital innovation and provided new thinking on how to improve the institutional environment for high-level digital innovation.
