Technology trajectories and strategies

While research and development expenditure and investment have been recognized for the last 50 years as one of the key factors explaining growth and industrial dynamics on a macro–economic level, the literature concerning the functions and role of RD the problem of the incompatibility between the indicators and instruments evolved by these different theoretical references; and, lastly, the use in micro–economic analysis of concepts and methods adapted from macro–economic analysis and which are not transposable. The paper is dealing with three main themes: the dynamics of technology; the structure or composition of R&;D costs according to the position of a firm along its technology trajectory; the strategic and organizational questions which follow from this relationship.
