Forms of knowledge and eco-innovation modes: Evidence from Spanish manufacturing firms

摘要

The paper investigates the knowledge drivers of firms' eco-innovations (EI) by retaining the diverse nature of their target. Different internal and external knowledge sources are examined and the evidence of El-modes is searched for with respect to a sample of Spanish manufacturing firms covering the 2007-2009 and 2010-2012 periods. An "attenuated" Science, Technology, EI-mode prevails internally, with R&D more pivotal than either embodied or disembodied non-R&D knowledge, depending on the EI strategy. Externally, synthetic knowledge matters more than the analytical one, suggesting instead a Doing, Using, Interacting El-mode. Hence, a dichotomic combination of the two modes emerges across the firm's boundaries. However, remarkable differences are in place, depending on whether EIs target efficiency or non-efficiency related environmental improvements. Our evidence also shows that internal and external knowledge turn out difficult to combine, both within and across modes. (C) 2016 Elsevier B.V. All rights reserved.
