Abstract:
This paper aims to shed light on the role of technological opportunities for green innovation by
studying the case of Green ICT innovation. We test two hypotheses: (1) Firms active in low-opportunity
technological areas are less innovative; (2) Firms active in low-opportunity technological areas are more
likely to change their direction of technical change. To do so, we construct a firm-level panel data set for
the years 1992-2009 combining patent data from the European Patent Office with firm-level data from the
German Innovation Panel (Mannheim Innovation Panel). The results are based on dynamic count data
estimation models applying General Methods of Moments estimators. Our results support our hypotheses:
firms active in low-opportunity technological areas are less innovative but are more likely to switch from
pure ICT innovation to Green ICT innovation.
