Notes: This table examines how exposure to China import penetration affects local-level employer concentration. The table uses three-digit SIC industries to compute HHI, China exposure, log(employment), and log(plants per segment). The dependent variable is log(HHI) as defined in Table 1. t-statistics based on standard errors adjusted for sample clustering at the county level are reported below the coefficient estimates. The numbers of observations are rounded to the nearest thousand to follow the U.S. Census Bureau’s disclosure rules.
