We investigate the merger behavior of firms in the plant biotechnology sector using firm-level patent data for public and private firms in the 1980s and 1990s. Conditional logit estimation is used to estimate the probability that the firms will match in mergers and spinoffs. We calculate several patent portfolio-based measures of complementarity and spillovers between firms, and find that both are important to defining a good match of acquirer and target. However, complementarities provide the more robust explanation. The mergers and spinoffs observed in plant biotechnology may have been designed to overcome the anti-commons problem of mutually blocking technology, an extreme form of complementarity. Our results highlight the need to integrate patent and competition policy. 相似文献

Our study examines the conditions under which firms enter into strategic alliances subsequent to knowledge spillovers. We propose that spillovers serve as signals of knowledge dependence and potential complementarity, encouraging alliance formation to enable better learning and limit appropriation. We posit that the likelihood of a knowledge alliance subsequent to a spillover is contingent on the specialization of each of the firms in the knowledge involved in the spillover. We also hypothesize that the effects of such specialization on knowledge alliance formation are moderated by technological ties and geographic distance between the dyad involved in the spillover. Our results demonstrate significance for the effects of specialization, supporting learning and appropriation motivations. Technological ties strengthen while geographic distance weakens the relationship between specialization and alliance formation. 相似文献

The idea of constructing regional advantage (CRA) has recently been emphasized by scholars as a new way for firms to gain competitiveness in a globalizing learning economy. The rationale behind the idea is that advantages in a regional industry can be constructed by proactive public–private partnership. This article uses, and examines the relevance of, the CRA framework in analysing the development and functioning of the marine biotechnology industry in Tromsø, which is a fairly peripheral region in Norway. Despite the fact that much effort has been put into education and R&D at the University of Tromsø and related research institutes, and the fact that many public policy tools have intended to create a blooming marine biotechnology industry in the area, the results have so far been meagre. This article explains the rather weak results in terms of the number of firms and jobs in the marine biotechnology industry in Tromsø as being due to a lack of synthetic knowledge on how to industrialize research results and little spillover of market knowledge. With regard to more general theoretical lessons linked to the CRA framework, this article argues for seeing the concept of related variety in a broader industrial and geographical sense in peripheral regions. 相似文献

Since the late 1980s, technological advances and policy reforms have created new opportunities for private-sector investment in India’s seed and agricultural biotechnology industries. These changes have had a significant impact on cotton yields and output in India, but less so for rice and wheat—the country’s main cereal staples—for which yield growth rates are tending toward stagnation. This analysis examines the structures of these industries, their potential effects on competition and innovation, and the policies that may improve both industry performance and the delivery of new productivity-enhancing technologies to India’s cereal production systems. Our findings suggest that more substantive policy reforms are needed to encourage further innovation, reduce regulatory uncertainty, and encourage firm- and industry-level growth, while continued public spending on agricultural research is needed to support technological change. 相似文献

AbstractNetwork systems like clusters are characterized by the coexistence of relational architectures with ties and nodes of different nature. While recent research has analysed how a set of structural features shape the dynamics and effects of one cluster network, the outstanding question is to what extent such features and outcomes are influenced by the concomitance of distinct content-related linkages. This paper integrates both network and evolutionary economic geography perspectives to develop and test a model that links innovation performance with the benefits that stem from technical and business relations. Data collected in a biotech cluster in the Valencia region (Spain) demonstrate the changing effect of brokerage and overlapping ties on innovation as a function of knowledge shared. Findings extend the theoretical understanding of how knowledge diffuses in clusters and provide valuable insights for both practitioners and policy makers. 相似文献
