摘要

This paper analyses the impact of green innovation on energy intensity in a set of 14 industrialsectors in 18 OECD countries over the 1970-2005 period. We match green patent stocksto energy intensity estimates at the sector level by applying a newly developed concordancetable (Lybbert and Zolas, 2014) to relate patents to their sectors of use. Following the frameworkof Berndt and Wood (1975), the model estimates a Translog cost function to measure theimpact of green innovation on energy intensity - next to other factors such as input substitutionand structural changes. We further distinguish between domestic and foreign innovation. Ourpreliminary results suggest that 1) green innovation is energy saving, and has played somerole in decreasing energy intensity in most sectors/countries - 2) short run elasticity of energyefficiency w.r.t. patents varies greatly across sectors and countries 3) both foreign and home innovationboth have an impact, and, interestingly, foreign innovation seems to matter in sectorswhere domestic innovation doesn’t - 4) input substitution, domestic innovation, foreign innovationand non-patented innovation contribute to a proportion of 51:10:26:12 to the decrease inlong term predicted energy intensity and 5) inputs are all pairwise substitutes, as measured byown-, cross-price and Morishima elasticities.
