1、 itif.org Decoupling Risks:How Semiconductor Export Controls Could Harm US Chipmakers and Innovation TRELYSA LONG|NOVEMBER 2025 U.S.export controls on semiconductor sales to China reduce U.S.chipmakers revenues,lower their R&D investment capabilities,and reduce industry employment.As such,U.S.policy

2、makers should keep semiconductor export controls to a minimum.KEY TAKEAWAYS ITIFs economic model estimates that U.S.firms could lose about$77 billion in semiconductor industry sales in the initial year after a hypothetical,one-time full decoupling with China.South Korean firms could gain about$21 bi

3、llion in sales,European Union firms$15 billion,Taiwanese firms$14 billion,Japanese firms$12 billion,mainland Chinese firms$9 billion,and other nations firms$5 billion of U.S.firms losses.U.S.industry R&D investments in semiconductors could decrease by about 24 percent,or$14 billion,compared with the

4、 status quo after a one-time full decoupling with China.The U.S.semiconductor industry could support over 80,000 fewer U.S.industry jobs and almost 500,000 fewer downstream jobs in the face of a full decoupling between the United States and China.INFORMATION TECHNOLOGY&INNOVATION FOUNDATION|NOVEMBER
