Bradford law in R&D expending of firms and R&D concentration

The applicability of the Bradford law to the R&D expending of firms is examined and its usefulness is proved. It successfully identifies core firms, peripheral firms and minor firms. It also provides a measure to evaluate the degree of R&D concentration to a small number of firms.
