特朗普政府，正在将学者“逼离”美国

Core Viewpoint - The departure of Matthias Doepke from Northwestern University highlights the growing concerns among academics regarding the current academic environment in the U.S., particularly under the Trump administration's policies that have increasingly targeted international students and scholars [4][9][18]. Group 1: Academic Environment - Doepke expressed that the academic atmosphere in the U.S. has shifted significantly, with a decline in the welcoming nature towards international students and scholars compared to when he first arrived [8][24]. - The tightening of policies under the Trump administration has led to reduced research funding and stricter scrutiny of international students and faculty, resulting in visa revocations and deportations [9][10][17]. - The uncertainty surrounding visa statuses has created a climate of fear among international scholars, making it difficult for them to pursue academic careers in the U.S. [22][31]. Group 2: Personal Experience and Decision - Doepke, who has lived in the U.S. for over 30 years and became a citizen in 2014, decided to leave due to the current environment not being conducive for raising a family and pursuing research [5][3]. - He has taken a position at the London School of Economics (LSE) and has expressed that many scholars are contemplating leaving the U.S., although practical challenges make it difficult for them to do so quickly [12][30]. - The decision to leave was influenced by a combination of factors, including concerns about the safety of his family and the overall academic culture shifting towards a less supportive environment for scientific exploration [11][16][21]. Group 3: Future Implications - The trend of scholars leaving the U.S. could lead to a significant loss of talent, as many may choose to pursue opportunities in Canada, Europe, or other regions with more favorable academic environments [31][34]. - Doepke noted that the current situation may deter future generations of international students from pursuing their studies in the U.S., as the opportunities that once existed are diminishing [24][25]. - The potential rise of other countries, such as China, as new centers for research and development could reshape the global academic landscape if the U.S. continues to lose its appeal [29].
