Innovation And Industry Evolution

Audretsch concludes that the structure of industries is characterized by a high degree of fluidity and turbulence, even as the patterns of evolution vary considerably from industry to industry. The dynamic process by which firms and industries evolve over time is shaped by three fundamental factors: technology, scale economies, and demand. Most important, the evidence suggests that it is the differences in the knowledge conditions and technology underlying each specific industry -- key elements in innovation -- that are responsible for the pattern particular to that industry.
