Spillover tecnologici e origine della tecnologia agricola
The Italian agriculture can be described as a technology taker sector dominated by suppliers. Technological spillover is the main source of technological change within the agricultural production processes. The Yale Technology Concordance (YTC} is applied to identify the innovations flow from other national sectors and other nations to Italian agriculture. A strong dependence from Chemical, Drug (especially foreigner) and Mechanical sectors emerges and it seems quite stable over the years. The intersectoral and international innovation flow matrix can be then used to define an R&D spillover stock whose impact on sectoral TFP and internal rate of return can be assessed.
