Regional Industrial Structure Concentration in the United States: Trends and Implications
利用企业层面数据测量美国制造业的区域集中度，分析其时空变化及与就业变动的关系，为理解区域产业结构对经济发展的影响提供实证依据。
abstract In a seminal article, Chinitz (1961) considered the effects of industry size, structure, and economic diversification on the performance of firms and regional economies. His inquiry suggested a related but conceptually distinct issue: how does the extent to which a regional industry or industrial sector is concentrated in a small number of firms affect the local performance of that industry? The question has not been addressed systematically in empirical research other than case studies, principally because accurately measuring regional concentration requires firm‐level information. This exploratory study uses confidential plant‐level data to gauge concentration in manufacturing industries at the regional scale across the continental United States, to explore changes over time in geographic patterns of concentration, and to investigate associations between regional industrial structure concentration and changes in employment. The implications for understanding the impacts of regional industrial structure on economic development processes are discussed.
