Analysis of scientific research cooperation network in the Guangdong-Hong Kong-Macro Greater Bay Area based on highly-cited papers

Objective To analyze the structure and characteristics of scientific research cooperation network in 11 cities of the Guangdong-Hong Kong-Macro Greater Bay Area based on the cooperation in highly-cited papers. Methods The citation network was plotted for scientific research cooperation and its hot spots in the Guangdong-Hong Kong-Macro Greater Bay Area were analyzed with the analysis tools of scientific knowledge graphs. Results Guangzhou, Hong Kong and Shenzhen have become the important cooperation center in scientific research, the colleges and universities-dominated research institutions were the backbone in scientific research cooperation, and the Guangdong-Hong Kong-Macro Greater Bay Area has formed its advantages and characteristics of hot spots in research on clinical medicine, chemistry, computer science and gut microbiological macrogenomics. Conclusion The scientific research cooperation is becoming increasingly close in the Guangdong-Hong Kong-Macro Greater Bay Area with great achievements made in advantageous disciplines and hot spots. It is thus suggested to take comprehensive measures for further improving the scientific research cooperation level and international impact power in this area.
