Localized Technological Change in Italy
Chapter 12: Knowledge Generation and Vertical Dynamic Interdependence Within Industrial Filieres: Econometric Evidence on Total Factor Productivity Growth
12. Knowledge generation and vertical dynamic interdependence within industrial filieres: econometric evidence on total factor productivity growth 12.1 INTRODUCTION We now want to test the hypothesis that the Italian case was, for four decades after World War II, an example of a virtuous innovative system, developing and emphasizing the interdependence between innovative processes across manufacturing industries. The relevance of dynamics of sectoral relationships is a remarkable feature of Italian technological and structural change in the 1950–80s period. The hypothesis of the emergence of an original Italian innovation system can also reconcile the evidence of low levels of innovative activity, as measured by traditional indicators, such as R&D or patents, and high levels of total factor productivity, and try to solve the apparent Italian paradox. The interpretive model put forward can form the basis of an empirical investigation making it possible to draw attention to the plurality of innovative mechanisms operating in the Italian industrial system. 12.2 THE SECTORAL EVIDENCE Looking across industrial sectors, the following hypotheses can be formulated: 1. In the whole industry, TFP increased as the result of the 162 M2517 - ANTONELLI PRINT.indd 162 26/01/2011 08:44 Knowledge generation and vertical dynamic interdependence 163 2. 3. introduction of technological (process and product) innovations induced by growth in aggregate demand and in wages; Innovative activity and growth in the upstream sectors were stimulated by the combination of expansion of the derived demand for capital goods and intermediary inputs in the downstream sectors (Smith–Young–Kaldor demand...
