The knowledge spillover theory of entrepreneurship (KSTE) explores the effects that new knowledge and proximity have on the exploitation of entrepreneurial opportunities and the resultant creation of start-ups. This paper aims to identify the types of knowledge spillovers that affect entrepreneurs in the early stages of start-up development. A conceptual model is proposed, using a multi-case study approach involving high-tech start-ups that have attended accelerator and incubator programs in Greater London, United Kingdom. The research involved 32 semistructured interviews with chief executive officers and cofounders of start-up companies. Our findings suggest that entrepreneurs are influenced by various forms of knowledge spillover which assist in determining the strategic decision of the company, in terms of formation, including partnerships or alliances, allocation of Research and Development budgets, and engagement in product innovation. Further observations confirm that high-tech start-ups focus on a fast pace of constant product innovation to cover identified gaps in the market. One significant finding is that start-ups use various technological platforms to access knowledge spillovers which challenge the ideas of geographical proximity present in existing KSTE understanding.

This paper looks at firm-level differences in R&D intensity and sales from product innovations. R&D intensity and innovative sales are explained by a model using harmonised firm-level data from the Third Community Innovation Survey for three European countries: Belgium, Germany and Spain. For each country, the average estimates suggest that incoming knowledge spillovers, research cooperation, appropriability and human capital all exercise a positive influence on R&D intensity and, through this, on innovative sales. Quantile regressions indicate that, although there are differences between countries, the joint relative impact of incoming knowledge spillovers and research cooperation tends to increase quantile-wise in relation to that of appropriability. This suggests that strong innovators have a more open innovation process. [ABSTRACT FROM AUTHOR]

This paper explores the decision of small- and medium-sized enterprises (SMEs) to participate in official standard setting alliances. Based on micro data of German firms in the electrical engineering and machinery industry, we show that innovation-related variables follow the predictions of our hypotheses. Research and development (R&D) intensity exhibits an inverse U-shaped relationship on the likelihood to join alliances. The positive relation suggests that SMEs aim to access the knowledge of larger firms whereas the negative relationship indicates that SMEs exceeding a certain threshold of R&D activity are reluctant to participate in standardization because their knowledge is too essential to disclose to competitors. The importance to access external knowledge via standardization committees is underlined by a positive correlation with the relevance of incoming knowledge spillovers and a negative correlation with the relative size of companies’ patent portfolios. Besides these variables, we also explore the traditionally considered factors for alliance formation and show that firm size and export intensity are positively correlated with participation.

This paper examines the recent development of industrial technology in China using a rich and novel Chinese patent dataset, which allows us to get a comprehensive view of the invention activities in China. Combing patent statistics with R&D and Foreign Direct Investment (FDI) indicators, we found that the R&D activities at local universities and research institutes were the most important external factors behind the increase in domestic firms' patenting activities. FDI, on the other hand, appeared to have a negative effect on domestic firm patenting, at least until foreign market demand for domestic production is established. [ABSTRACT FROM AUTHOR]
