Innovation is a key driver of productivity and economic growth and of the competitiveness of agriculture and other industries. However, because the innovation process is complex and innovation data is limited, its links with R&D investment and its effects on productivity are difficult to quantify. This RIRDC report evaluates the role of innovation adoption within the agricultural innovation process. Specifically, a conceptual framework is developed to assess the innovation process and the interacting drivers influencing innovation adoption and productivity, including R&D investment.
