150 studies (including some case studies) done exclusively on public enterprises are comparative studies of public enterprises and enterprises in the private sector have been reviewed under five main OB dimensions (general, organizational dynamics, person in the organization, group and organizational processes, and organizational change and innovations). Analysis showed that 69 studies were on public enterprises in general, whereas other types of enterprises included manufacturing industry (36%), non-manufacturing industry (7), banks (29), and service organisations (9). The trend showed that studies in four areas of OB were well distributed 32-40 studies in each area). The trends have been discussed and the needs to develop better methodology, more insightful theories, and more effective intervention strategies have been suggested.
