Table 8 reports the interaction terms used in the panel regressions. There are six industry characteristics, each measured relative to the manufacturing average. Therefore a value of 0 for the log K/L ratio term means that the industry has the same capital to labour ratio as manufacturing as a whole. The interaction term are the physical capital to labour ratio; the energy input to physical capital ratio; the ratio of non-production workers to total workers; the ratio of R&D capital to physical; the export to output ratio; and the import to output ratio.
