Abstract:Collaborative innovation and integrated development of science and technology are vital method to promote regional technological innovation. Although the subjects of collaborative innovation in the Guangdong-Hong Kong-Macao Greater Bay Area are gradually matured, problems such as weak inter-subject correlation, poor cross-border flow of scientific research achievements and difficulties in transformation restrict the collaborative development of science and technology. In order to investigate the collaborative development and integrated construction in the Bay Area with the carrier platform as the connecting hub, this paper proposed to explore the path of building a high-level technology carrier platform in the Guangdong-Hong Kong-Macao Greater Bay Area by focusing on innovative market players, dominant disciplines, joint laboratories, incubation Spaces and innovation alliances by comparing the development modes of carrier platforms in the world's three Bay areas. Finally, countermeasures and suggestions are given from three aspects: strengthening the carrier platform's status as "innovation hub", building a carrier platform to realize multi-industry integration, and deep-rooted typical innovation platform, so as to provide new reference for promoting the development of scientific and technological collaborative innovation in the Greater Bay Area.
