In recent years, the level of China’s digital economy development has been increasing, but the problem of low coordination between the digital innovation ecosystem and digital economy development still exists. This paper constructs the evaluation index system of the digital innovation ecosystem and digital economy development, respectively, and analyzes the development level of the digital innovation ecosystem and digital economy according to the entropy value method evaluation model. To explore the coupling development status of the digital innovation ecosystem and digital economy, the coupling development of the two is analyzed through the coupling degree model and the coupling coordination degree model. According to relevant calculations, from 2017 to 2023, the average development composite index of China’s digital innovation ecosystem 0.3189 increased by 0.4920, and the average development composite index of the digital economy rose from 0.1622 to 0.3524. The coupling degree between the national digital innovation ecosystem and the digital economy increased from 0.2125 to 0.64319, with an obvious increase in the coupling degree. The degree of coupling coordination between the two regions is specifically characterized by a gradual decrease from the eastern areas to the western regions, with certain regional differences.
