Abstract: Taking 206 enterprises in strategic emerging industries as research samples, this paper constructs an SEM model with corporate network power and innovation performance as variables and digital capability as an intermediary to study the internal mechanism of dynamic changes in network power affecting innovation performance under the digital transformation of enterprises. The results show that corporate network power plays a positive role in innovation performance, and digital synergy significantly improves innovation performance, and plays an effective intermediary role between network power and innovation performance. Therefore, under the background of digital transformation, attention should be paid to the effective use of network power of core enterprises, so as to achieve a significant improvement in the overall competitiveness and innovation performance of the enterprise network.
