9万亿投资承诺背后：美国制造业回流，可能只是“画饼”？

Core Viewpoint - The Trump administration claims to have attracted over $9 trillion in investment commitments since taking office, focusing on high-end sectors like semiconductors, AI, and automotive, but this figure is viewed as more of an "empty promise" than a reality [1][8]. Group 1: Investment Commitments - The reported commitments include $1 trillion from Saudi Arabia, $1.4 trillion from the UAE, and $165 billion from TSMC, but most of these figures are based on future promises rather than actual investments [3]. - Currently, the actual funds that have materialized amount to less than $1 trillion, representing only 11% of the total commitments [3]. Group 2: Manufacturing Challenges - Experts highlight that the return of manufacturing to the U.S. contradicts global supply chain dynamics, as the U.S. has high construction and operational costs, making it difficult to become a global manufacturing hub [5]. - The commitments from other countries may be influenced by U.S. administrative pressure or serve as a temporary measure to avoid conflict, rather than genuine intentions to invest [5]. Group 3: Reality of Investment - The Trump administration's claims of revitalizing the manufacturing sector are undermined by the lack of actual projects and the ongoing issue of hollowing out in U.S. manufacturing [8]. - The notion that $9 trillion in commitments can solve manufacturing challenges is seen as unrealistic, as companies prioritize profit over mere promises, and the high-cost environment in the U.S. is a significant deterrent [8].
