In the past two decades small firms have provided much impetus to the development and growth of the new high technology industries. Drawing upon detailed research this book evaluates the contribution of small biotechnology firms to current production with a prognosis on the potential for future expansion. The research particularly focuses on the relationship between small and large firms and the extent to which small firms are emerging to lead the sector in terms of innovation and growth or are being absorbed into the existing large firms of related industrial sectors (e.g. pharmaceuticals, chemicals).
