Audit technological innovation is the technical basis for the high-quality development of auditing. Exploring the paradigm of audit technological innovation in the new era has important theoretical value and practical significance. Based on the audit patent data, this study constructs an ecological network of audit technological innovation by using the social network analysis method, reveals its evolution process and explores the impact of the network location of innovative actors on their innovation performance. The results show that the evolution presents a clear logical model. The centrality of innovation network has a significant positive effect on the performance improvements of innovation entities. It is also observed that for entitles with low innovative niche and potential, the positive impact of innovation ecological network is larger than that of the comparative ones. The innovation entities with low ecological niche can more easily improve their innovation performance by integrating into the audit technological innovation network.
