The domination of a limited range of industries in a region. Sölvell et al. (2006) DRUID Summer Conf. analyse industrial specialization in terms of absolute number of employees, specialization, and dominance, and identify nineteen ‘three-star’ regional clusters in the ten new EU states. Svaleryd and Vlachos (2002) J. Int. Econ. 57 find that the financial sector has greater impact on industrial specialization among OECD countries than do differences in human and physical capital.
