Knowledge base combinations and firm growth 总被引:1,自引:0,他引:1
The link between knowledge and firm growth has been a core topic in economics of innovation for a long time. However, despite strong theoretical arguments, empirical evidence remains inconclusive. One important reason for this conundrum may be the failure of standard indicators to capture firm innovation activities comprehensively. We contribute to overcoming this limitation by looking in the knowledge processes that drive variegated forms of innovation and aim thereby to establish a solid relationship with firm growth in more detail. Our arguments draw on the differentiated knowledge base approach, distinguishing between analytical, synthetic, and symbolic knowledge. We measure the three types of knowledge bases with detailed longitudinal linked-employer-employee micro-data from Sweden. Econometric findings based on a very large sample of small and medium-sized firms indicate significantly positive effects of the three knowledge types, and in particular combinations thereof, on firm growth. In addition, we show that not only high-growth but also slow-growth firms benefit immensely from the use of combinatory knowledge bases. We find evidence on a curvilinear relation between knowledge bases and growth of firms. Beyond certain thresholds increasing the knowledge bases further results in decreasing firm growth. Our results remain robust in a wide range of specifications and econometric models. 相似文献

Research has shown that mastering information literacy (IL) competencies helps students perform better academically or otherwise. However, there is limited evidence that indicates a relationship between IL teaching methods and IL competencies. This study investigates the impact of IL teaching that incorporates appropriate pedagogical approaches on students' applicability of IL competencies. The study was carried out in four secondary schools in Singapore. Students were organized into groups of five and were assigned a group project. Those in the experimental sub-clusters were exposed to various intervention approaches, while the control sub-clusters were left on their own to carry out the project. Three independent, neutral teacher-examiners evaluated the results of the group reports and projects. The results showed significant differences in the achievements of students in the experimental groups that underwent both interventions as compared to the control groups. 相似文献

Innovation activities in the German business sector showed two opposing trends over the past two decades: While total innovation expenditures grew substantially, the number of firms conducting innovation activities fell sharply. In this paper, we explore the mechanisms behind the declining trend in the share of innovation active firms. Considering both input (R&D activities) and output (introduction of innovations), we model innovation decisions as a multi-stage process using continuous-time Markov chain analysis. We base our analyses on a 14-year panel from the German part of the Community Innovation Survey. Our results show that smaller firms and firms in sectors with less innovation competition are more likely to stop innovating. We also show that better financial situation and public funding can mitigate the trend towards a falling share of innovating and R&D-performing firms. 相似文献
