Space‐Time Variations of Human Capital Assets Across U.S. Metropolitan Areas, 1980 to 2000
研究了1980至2000年间美国大都市区人力资本结构变化，发现认知文化技能向大城市集中，而体力实用技能向小城市转移，但大城市仍保留部分体力技能。
This article examines the changing structure of human capital in U.S. metropolitan regions from 1980 to 2000. Data are drawn from the Dictionary of Occupational Titles and from the Integrated Public Use Microdata Series. Intensive empirical investigation leads to three main conclusions. First, forms of human capital in the United States are becoming more oriented to labor tasks that call for cognitive-cultural skills. Second, cognitive-cultural skills are accumulating most intensively in large metropolitan areas. Third, physical or practical forms of human capital are increasingly being relegated to smaller metropolitan areas. That said, important residues of human capital, focused on physical or practical tasks, remain a durable element of the economies of large metropolitan areas. I offer a brief theoretical explanation of these results.
