Regional variations of firm births, deaths and growth patterns in the UK, 1980-1991

One of the debates around new firm formation across sub-national territories focuses on whether regional differences in industrial structure are more important influences than regional differences in individual industry performance. The present research, using Value Added Tax (VAT) registration data, attempts to make a contribution to this debate in the United Kingdom (UK) context using a shift-share covariance model. Firm de-registrations and, as a consequence, net changes in firm stocks are also analyzed with similar questions in mind. The findings show that although the effects of industrial mix are significant across most regions, in several key regional contexts the industrial competitive effect dominates. The issue of the role of regional industrial concentration forms a second major theme of this paper. This basically involves a questioning as to whether concentration is a positive or negative force for new firm formation. The results of this research indicate that industrial concentration, measured through localization, is more important for firm deaths than for firm births (although significant fbr both), but not particularly relevant to the understanding of the net outcome of entry and exit processes. In the UK, regions with higher levels of industry concentration seem to be associated overall with relatively lower levels of both firm births and deaths.
