More than 381,000 people at 11,000 Michigan firms are working in high-tech, highly productive advanced manufacturing jobs – nearly two-thirds of the state’s manufacturing base, according to a new University Research Corridor study. The report, prepared by East Lansing-based Anderson Economic Group (AEG), shows Michigan’s particular strengths in research-related advanced manufacturing: a third of the research and testing jobs in the Midwest are in Michigan and more than half of the state’s advanced manufacturers are seeing productivity gains exceeding the U.S. average while employing 10% of the state’s workforce.
