Who drives smart growth? : the contribution of small and young firms to inventions in sustainable technologies

Europe#s innovation potential is currently dominated by well-established large companies. In most member countries the bulk of R&D expenditures is spend by large companies. Following OECD data, SME's share in total R&D spending amount to 8% in Germany or Japan, around 15% in US, France, Korea or Italy, about 20% in Sweden, Finland or Switzerland, about 30% in Netherlands, Austria or Poland, and about 50% in Poland, Ireland, Slovakia or Greece. First of all, these figures point to a considerable heterogeneity with regard to the importance of SMEs in national R&D activities. However, young companies are said to be the driving force behind radical innovation which will be a source of employment and growth in future. In addition, the weakness of Europe is not only the small number of hightech startups but more specifically the number of hightech startups which accomplish continuing, rapid growth. However, there might be significant technology specific heterogeneity with regard to the contribution of SMEs and young firms to innovation. The central question of the paper is whether SMEs and young firms might be agents with a special contribution to new growth path in Europe. We took new renewable energy technologies as an example at test whether the contribution of SMEs and young firms is larger in this technology area compared to invention as measured by patenting. In order to focus on the most valuable patents we use patent applications at the European Patent Office which were also applied for patent production at the USPTO and the Japanese Patent Office ("triadic patent applications"). The analysis proceed in two steps: The paper looks first at trends in international patenting and compares triadic patent application in the field of energy with all triadic patent application by country of inventors. The idea is to highlight the role of EU and its member states in invention activity in a technology-field which is of special relevance for a new, sustainable growth path. In the second step we look at the contribution for SMEs and young firms to such a new growth path by a detail analyses of triadic patent application by German companies as the SMEs share to R&D is the smallest compared to all other EU member states as well as compared to OECD member states (except Japan). The focus on Germany is motivated for two reasons - to ease the analysis and to focus on the most extreme case of the firm-size R&D distribution which is observed in EU and OECD member states. [...]
