Abstract: Based on the informationization and digitalization of innovation knowledge in the digital economy era, this paper constructs a model of the influence of Internet application on innovation of manufacturing enterprise, analyzes the intermediary effect of information connectivity and heterogeneity factor by taking the survey data of manufacturing enterprises of the World Bank as samples, using the Logit regression method and the intermediary effect model. The results show that use of the Internet by manufacturing enterprises has a significant positive impact on decision-making of innovation input, intensity of innovation input and innovation output. The information connectivity between enterprises and suppliers or customers in the upstream and downstream of the industrial chain plays an intermediary role. Among them, Internet information connectivity has a significant intermediary effect on the innovation of consumer goods manufacturing enterprises, but has an insignificant effect on industrial product manufacturing enterprises. The information connection with customers has a significant mediating effect on the innovation output of small and medium-sized enterprises. The results of research are helpful to explore the influence mechanism of information elements on enterprise innovation in the era of digital economy, and provide reference for different types of enterprises to implement the digitalization strategy and obtain “connection dividend”.
