Abstract: Abstract: The agglomeration of advanced R&D talents has great strategic value for the high-quality development of manufacturing industry in China. However, how the Sino US trade war affects the agglomeration of advanced R&D talents in manufacturing industry is a major theoretical and practical problem. Base on a big micro enterprise data named "innovation survey enterprise database", this paper constructs instrumental variables with the policy documents of technology introduction by the Chinese government, and studies how the Sino US trade war affects the agglomeration of advanced R&D talents in manufacturing enterprises of China. The main findings are as follows: Firstly, the decline of foreign technology introduction is beneficial for manufacturing enterprises of C_Min or C_Mid to improve the agglomeration of advanced R&D talents; Secondly, the decline of foreign technology introduction has a restraining effect on the agglomeration of advanced R&D talents of manufacturing enterprises of B_Max; Thirdly, the Sino US trade war is beneficial to improve the agglomeration of advanced R&D talents in "Talent Snatch War" Cities objectively. This paper provides valuable reference for the Chinese government to properly handle the U.S. technological blockade against China and to formulate appropriate policies for talent introduction in "Talent Snatch War" cities.
