Comparing the collaboration networks and productivity of China-born and US-born academic scientists

Chinese scientists constitute the largest group of foreign-born tenure-track faculty in science and engineering (S&E) fields in the USA, and have become a target of recent Chinese government efforts seeking to attract them back to China. This study examines the differences of collaboration networks between Chinese scientists and US-born scientists working in the USA. The findings show significant differences in the size, composition, and role of collaboration networks of Chinese scientists, and how these networks differently impact their productivity. The networks of scientists born in China are smaller, more dispersed, and less communicative. However, despite those networks and less benefit from traditional research resources, Chinese scientists appear to be more productive than their American colleagues are. The study improves understanding of this important group in the USA's research enterprise and also provides insights for science policy.
