This paper examines the spatial pattern of U.S. county employment growth in high-tech industries. The spatial growth dimensions examined include industry cluster effects, urbanization effects, proximity to a college, and proximity in the urban hierarchy. Growth is examined for overall high-tech employment and for employment in various high-tech sectors. Econometric analyses are conducted for a sample of all counties and for metropolitan and non-metropolitan counties separately. Among our primary findings, we do not find evidence of positive localization or cluster growth effects, generally finding negative growth effects. We instead find some evidence of positive urbanization effects and growth penalties for greater distances from larger urban areas.
