Local Industrial Dominance and Earnings Attainment
借鉴生态学中地方产业主导的概念，研究大都市劳动力产业分布如何影响工人收入，发现工人所在产业在本地占主导时收入显著更高，且该效应在核心产业、金融商业服务及公共管理领域更强。
Drawing on the ecological concept of local industrial dominance, we examine how the industrial distribution of the metropolitan labor force influences workers' earnings. Industrial dominance is defined as the proportional overrepresentation of the local labor force in a given industry or industrial sector. A contextual analysis of census microdata for the largest 125 SMSAs shows that, within industries and sectors, workers in metropolitan areas in which their industry is dominant have significantly higher earnings than workers in areas in which that industry is less dominant. These results holdfor two different measures of dominance andfour racelsex groups. The effects of local dominance on earnings appear stronger for industries in the core and state sectors, for financial, business and personal service functions, andfor public administration. The influence of dominance is partly explained by the tendency of locally dominant industries to be composed of larger establishments.
