Abstract: The new round of technological revolution presents new characteristics such as breakthroughs in multiple fields, disciplines, and groups. Innovative entities absorb and integrate heterogeneous innovation resources across boundaries such as technology and organization, achieve the integration of technologies, and emerge innovative points at the intersection of technology fields, driving the formation of cross-border innovation in emerging technologies. By analyzing the cross-border integration of technology and the cross-border cooperation of innovative entities, an emerging technology cross-border integration network was constructed with cooperation sub networks, technology sub networks, and auxiliary sub networks. The mechanism of emerging technology cross-border integration was deeply analyzed, and the cross-border integration of 5G technology and AI technology was taken as the research object. Patent data was used to empirically analyze the emerging technology cross-border integration network. Research has found that with the cross-border integration of 5G technology and AI technology, the number of innovative entities and technology fields increases, and the cooperative relationship between innovative entities tends to stabilize; The degree of integration between technological fields has increased, and the breadth and depth of cross-border cooperation among innovative entities and technology integration have increased; Universities and technology-based enterprises are the main forces driving the cross-border integration of 5G technology and AI technology; The cross-border integration of 5G technology and AI technology is mainly concentrated in the fields of electrical communication and computing, accelerating the development of technology applications such as intelligent vehicles.
