This article examines public policy and social welfare issues related to a recent trend in black business ownership: the decline of black-owned businesses in ‘traditional’ personal services serving a predominantly black clientele, and the corresponding increase of black-owned businesses in ‘emerging’ capital- and knowledge-intensive fields. It is argued that, while the growth of black business ownership in emerging fields is a sign of black economic progress, overall trends in black business ownership are not entirely positive. For one thing, the divergent trends in traditional and emerging black-owned firms reflect widening socioeconomic disparities within black communities. Moreover, the decline of traditional black-owned firms bodes ill for disadvantaged blacks in inner-cities. After reviewing the development of black business enterprise in the United States, trends in black business ownership since the 1970s are examined. Patterns of change in traditional personal services and emerging business services are then linked to social and economic transformations that have enabled many blacks to participate in the larger national economy. The article concludes by discussing the implications of declines in traditional black businesses for black well-being and for public policy.
