Based on 1182 dyads of venture capitalists and German portfolio companies involved in a financing round between 2002 and 2007, the study here examines the importance of spatial proximity between investors and investees in a dense economy. Analysis of this data shows that the probability of a financing relationship decreases by 8% if the journey time increases by one standard deviation. For deals involving very small or very large investment sums, and for less experienced venture capitalists and lead investors, spatial proximity is particularly important. The results suggest that even in economies with a dense infrastructure such as Germany spatial proximity between investor and investee impacts the likelihood of an investment.  相似文献

The main objective of this paper is to test the Porter hypothesis by assessing static and dynamic effects of environmental policy on productivity. According to the hypothesis, stringent environmental regulations have dynamic effects on firm performance, and these effects eventually generate profits that offset the adaptation costs. We extend previous analyses by using unique data on environmental protection investments in the Swedish manufacturing industry as a proxy for environmental stringency. These data enable us to separate environmental protection investments into pollution prevention and pollution control. This distinction is crucial since the hypothesis claims that it is investments in prevention that have positive dynamic effects on firm performance. To test the hypothesis, a stochastic production frontier model is estimated where firm inefficiency is a function of investments in environmental protection. In general, we find no support for the Porter hypothesis within the time frame of our study, indicating that environmental regulations lead to efficiency losses. This result is even stronger in the harshly regulated pulp and paper industry.  相似文献

Mixed methods research is becoming an increasingly popular approach in several fields. However, its application in the field of entrepreneurship has not been studied. The authors reviewed the use of mixed methods research in three entrepreneurship journals and two leading generalistic journals that publish entrepreneurship research, examining the main purposes and designs. A total of 955 articles were reviewed and 81 mixed methods studies were identified. The analysis of these articles revealed opportunities associated with the application of this approach. Mixed methods may help to improve entrepreneurship research addressing challenges emphasized in earlier studies. Suggestions on why and how to use mixed methods research are offered, and recommendations are provided to guide future mixed methods studies to advance our understanding of the entrepreneurial phenomenon.  相似文献

The study of gender differences in entrepreneurial self-efficacy to date has produced inconclusive results. Cross-cultural studies are virtually non-existent. The present study seeks to understand the complex interplay of biological sex, socialized gender-roles, and culture on entrepreneurial self-efficacy and motivation to become an entrepreneur. Findings indicate that among American business students the traditional view of “entrepreneur as male” is fading. For the next generation of business leaders and entrepreneurs, a new entrepreneur stereotype is emerging that balances stereotypical feminine and masculine characteristics. These findings were not replicated in Spain where traditional gender-role stereotypes associated with entrepreneurship persist, even among business students. Implications for entrepreneurial education are discussed as they relate to the development of skills associated with venture creation.  相似文献

This study aims to analyze how obstacles to industry–university relations affect the success of their cooperation models, using a sample of collaborations coordinated by the Technological and Industrial Development Center (CDTI) in research and development activities in service industries. The results show that for the industry partner the key considerations affecting the dynamics of cooperation with research organizations are missed deadlines and problems associated with the appropriation of results. The importance of these obstacles also has a negative effect on success, especially in aspects related to the results of the project and its overall performance.  相似文献

Since it implies a reduction in the quality and the quantity of the natural resources, environmental degradation is a present day problem that requires immediate solutions. This situation is driving firms to undertake an environmental transformation process with the purpose of reducing the negative externalities that come from their economic activities. Within this context, environmental marketing is an emerging business philosophy by which organizations can address sustainability issues. Moreover, environmental marketing and orientation are seen as valuable strategies to improve a firm’s competitiveness. However, the literature that has analyzed the link between environmental strategies and firms’ results has been inconclusive and contradictory. In this study, we propose and test a model that analyses how the implementation of ecological issues within a firm’s marketing strategy and orientation influences organizational results. Data were obtained through a survey sent to Spanish manufacturing firms. The results show that environmental marketing positively affects firms’ operational and commercial performance and this improvement will influence their economic results. Moreover, environmental marketing is revealed as an excellent strategy to obtain competitive advantages in costs and in product differentiation. Thus, this study agrees with the researchers who affirm that environmental strategies positively affect firm’s competitiveness while reducing environmental impact.  相似文献
