Research on existing users" participation in R D innovation is mainly focused on special users such as leading users. How ordinary users participate in R D and innovation is not yet clear. In the context of the intelligent era, the empowerment of intelligent technology provides conditions and possibilities for ordinary users to participate in corporate R D and innovation. Based on the I-space theory, this paper analyzes the information resources required for R D and innovation, as well as the characteristics and spatial positioning of information resources owned by ordinary users. Describe innovation as a moving route in I space. By comparing the traditional innovation path and the user innovation path, the empowerment dependence of the user innovation path in the I space is discussed, and the assistive effect of intelligent technical methods on ordinary users" participation in R D and innovation. Based on this, a user innovation and intelligent empowerment mechanism is proposed. Finally, the research was carried out with Lego as an example, and the theoretical method was verified by application.
