Intellectual Repatriation and Network Bridging:Innovation Contributions of U.S.-Educated Returnee Science and Technology Talents in Guangdong Universities
摘要
Abstract
Understanding the multifaceted mechanisms underlying the cross-border migration and knowledge flows of overseas-returned science and technology talents is essential for enhancing innovation ecosystems in emerging economies.This study offers new empirical insights into these dynamics while providing context-specific policy recommendations for universities in Guangdong Province and similar regions.By optimizing talent recruitment and cultivation strategies,institutions can improve the targeted attraction and sustained support of high-value overseas returnees.Drawing on in-depth interviews with ten U.S.-educated science and technology talents who have returned to universities in Guangdong,the research examines the core mechanisms and constraining factors of their innovation contributions through two key dimensions:knowledge spillovers and technology transfer,and social networks and research collaboration.The findings reveal that these returnees effectively facilitate the cross-border transfer and localization of tacit knowledge via youth talent development and the conversion of advanced knowledge and technologies.Moreover,the extensive international networks they built abroad position them as distinctive"bridge"talents,uniquely linking domestic and overseas academic and industrial communities.However,U.S.policies promoting"decoupling"in scientific research with China since 2018 have significantly disrupted these collaborative networks,imposing notable institutional constraints on the bridging role of returnees.To address this problem,the study recommends strengthening talent introduction services,developing robust international research collaboration platforms,and constructing more resilient cross-border academic networks.Such measures would better unleash the innovation potential of overseas-returned science and technology talents and enhance regional innovation capacity.关键词
