Innovative Activity and Industrial Structure
A dramatic slowdown of productivity growth in many countries has been the subject of considerable discussion in literature. Among the potential factors of this decline, a prominent role has been given to innovative activity. For too long, economists have taken technical change as exogenously determined. Productivity change and economic growth are related in various ways. Productivity is spurred by innovations, whereas innovations have to be seen as endogenously chosen by creative firms on the basis of current or expected market structure, factor costs and market demand (and hence economic growth). Furthermore, industrial structure is changing due to innovative activity: Business firms innovate in order to grow. The phenomenon under study can be fully understood only by exploring a plex dynamic process, the process of industry evolution. It was Schumpeter (1942) who must be granted credit for bringing these connections to light. His ideas have attracted increasing interest in recent years and an excellent review of work on innovative activity is given by the contributions of Kamien Schwartz (1982), Nelson --Winter (1982) and Scherer (1980, 1984). As stressed by Nelson --Winter (1982) and Winter (1984), the process of industry evolution might be plex to be fully analytically tractable. To provide a clear view of
