The network of intersectoral innovation flows can be proxied by the product-embodied R&D flow matrix calculated using data on input-output tables and sectoral R&D expenditure. Leoncini et al. (1996; 2000; 2001; 2005) used network analysis to compare intersectoral innovation flows among several countries based on a relative matrix approach; i.e., the normalization of intersectoral innovation flow matrix, which is conducted and assumed to remove the scale effects arising from size differences among industries and countries. This approach, however, can only provide a basis for comparison among constituent sectors within a certain column/row of the intersectoral innovation flow matrix. To overcome this limitation, the authors propose an alternative technique called the unit value approach, which eliminates the scale effects and the flaws caused by the data transformation of normalization. The evidence obtained from using various other approaches to examine the patterns of intersectoral innovation flows in Taiwan-together with a qualitative assessment-demonstrates that the proposed approach more accurately represents the reality of a technological system.
