The dynamics of industrial clustering in British broadcasting

This study examines patterns of clustering in the British broadcasting industry. It studies the effects of cluster strength on the growth of the firm and on rates of surviving entry. The results for this non-high technology industry make for an interesting comparison with earlier studies which have examined clustering patterns in some high technology industries. We find positive, large and statistically significant clustering effects in the British broadcasting industry, both in the growth model and the entry model. Moreover, these effects are very similar to those observed in the computing, biotechnology, aerospace and financial services industries.
