Energy and Material Efficiency Innovations: The Relevance of Innovation Strategies

This study explores the relationship between energy and material efficiency innovations (EMEIs) and innovation strategies employed by manufacturing firms
to develop their process innovations. Firms may mainly develop process innovations in-house, let them mainly develop by other enterprises or institutions, or they
or they may develop them jointly with external partners. The empirical analysis is based on data of European manufacturing firms obtained from the fourth
Community Innovation Survey. Our results suggest that EMEIs are related to process innovation strategies. Firms which let mainly develop their process
innovations by other enterprises or institutions tend to be less likely to introduce EMEIs at all and these firms are also less likely to introduce EMEIs
with stronger efficiency effects. Moreover, our results do not suggest that firms following the 'cooperation strategy' are more likely to introduce EMEIs
and to reach a higher EMEI performance than firms following the 'in-house strategy'. Hence, our results do not confirm the results of previous research
pointing to a positive relationship between environmental innovations and cooperation with external partners.
