资源简介:
National industrial concentration in the U.S. has risen sharply since the early 1980s, but there remains dispute over whether local geographic concentration has followed a similar trend. Using near population data from the Economic Censuses, we confirm and extend existing evidence on national U.S.
自20世纪80年代初以来,美国全国层面的产业集中度大幅攀升,但学界对于地方地理集中度是否呈现出类似趋势仍存在争议。本研究利用经济普查(Economic Censuses)中的近似人口数据,验证并拓展了针对美国全国层面的既有研究证据。
