The objective of the paper is to analyse the degree of heterogeneity across Professional Service sectors. While previous research concentrates on the criteria of industrial classification of these sectors, we propose an empirical analysis of employment structures and the associated skill bases. By shifting the focus from sectoral ‘boundaries’ to sectoral ‘structures’ we are able to appreciate under a novel perspective the emergence and evolution of specialization patterns.
