闪迪，放弃550亿美元半导体项目

Core Viewpoint - The cancellation of the $55 billion semiconductor manufacturing center by SanDisk in Flint, Michigan, is attributed to "national economic turmoil" as confirmed by the state's governor Gretchen Whitmer [3][4]. Group 1: Project Details - SanDisk had planned to invest in a super factory located in Genesee County, covering approximately 1,300 acres, with $260 million of taxpayer funds already allocated for preliminary development [5]. - The project was considered one of the best semiconductor construction sites in the nation during its years of preparation [6]. - The investment was expected to create around 12,000 construction jobs and up to 6,000 permanent jobs, significantly impacting the local economy [8]. Group 2: Political and Economic Context - The Biden administration's influx of federal funds into advanced manufacturing, including semiconductor companies, had initially supported the project [9]. - In contrast, the Trump administration, which took office in January 2025, has committed to reviewing and potentially halting certain expenditures, raising concerns about the economic stability in Michigan [10]. - Whitmer indicated that the uncertainty under Trump's administration, including threats of higher tariffs, contributed to SanDisk's decision to abandon the investment [11][12]. Group 3: Reactions and Future Implications - SanDisk has not publicly commented on the cancellation, as the company is in a "quiet period" before its investor earnings report [13]. - Matt Hall, the Speaker of the Michigan House, countered the narrative blaming Trump or national economic trends, arguing that tariffs are crucial for encouraging domestic investment [13]. - Local business leaders in Genesee County expressed strong support for the project, viewing it as a rare opportunity to create thousands of local jobs after years of economic decline [15].
