Abstract:As a knowledge-intensive enterprise, aviation equipment manufacturing enterprises mainly rely on independent innovation to drive their development. Taking the listed companies of aviation equipment manufacturing from 2010 to 2019 as samples, this paper analyzes the direct and indirect impact mechanism of digital input on enterprise innovation performance. The empirical results show that there is a significant positive correlation between digital input and innovation performance, and knowledge capability and risk-taking play a mediating role in the mechanism of digital input promoting innovation performance. The government subsidy can adjust the influence of digital input on knowledge absorptive capacity and play a positive role in the influence of digital input on enterprise innovation performance. Therefore, in the process of enterprise digital transformation development, we should consider the digital input and other factors in order to improve enterprise innovation performance.
