自2018年5月以来，美国联邦调查局等强力部门率先采取了一系列破坏双边人才交流与科研合作的消极举措，诱发了中美人才战。经过几轮的官方蓄意炒作，美国朝野在对华人才政策方面疑似达成了较为广泛的共识，使人才战成为了中美竞争新格局的重要一环。在梳理中美人才战基本历程的基础上，借助于大数据手段，通过网络舆情监测和数据挖掘，剖析美国在涉华人才议题方面的舆情生成机理，可以发现美方的舆情走势及所谓的"社会共识"源于少数强力部门和右翼政客的民粹操弄，需要由中美两国的专业部门、理性力量共同导控涉华人才议题的舆情走势，使中美人才战跨越第五象限，回归良性竞争的轨道。

Since May 2018, FBI and other American strong departments have initiated a series of negative measures that were detrimental to Sino-American talent exchange and academic cooperation. Subsequently, the Sino-American talent war broke out. After several rounds of official deliberate speculation, it seemed that the US authorities and citizens reached an extensive consensus on the talent policy towards China. The Sino-American talent war has turned into an important element in the new bilateral competition between China and the US. Based on an examination of the general history of the Sino-American talent war, this paper analyses the generative mechanism of America's online public opinions on issues concerning Chinese talents by means of big data and data mining. The result shows that some American right-wing politicos and strong official departments manipulate the public opinions and the so-called "social common sense" by populism means. Professional institutions and rational power from the two countries should work together to guide and control the trend of online public opinions, and lead the Sino-American talent war to go beyond the "fifth quadrant" and return to the normal track of benign competition.
