Open innovation in SMEs—An intermediated network model     

Sungjoo Lee  Jinwoo Park 《Research Policy》2010,39(2):290-300

In spite of increasing interest in open innovation, discussion about the concept and its potential application to the SME sector has been excluded from mainstream literature. However, given that the argument about the effect of firm size on the effectiveness of innovation is still ongoing, it is worth addressing the issue from an SME perspective. That is the focus of this article, which seeks, firstly, to place the concept of open innovation in the context of SMEs; secondly to suggest the input of an intermediary in facilitating innovation; and finally to report accounts of Korean SMEs’ success in working with an intermediary. The research results support the potential of open innovation for SMEs, and indicate networking as one effective way to facilitate open innovation among SMEs.  相似文献

Determinants of proactive and reactive technology licensing: A contingency perspective     

Ulrich Lichtenthaler 《Research Policy》2010,39(1):55-66

Industrial firms increasingly attempt to license their technologies apart from applying them in their own products. Because of the imperfections in technology markets, an active approach towards technology licensing does not automatically result in licensing transactions. To balance prior research, which has focused on licensing transactions as the outcome of licensing intentions, we take a contingency view to analyze how characteristics of a firm's innovation ecosystem determine different strategic types of licensing. Specifically, we distinguish proactive licensing, which refers to identifying recipients for technology transactions, and reactive licensing, which relates to offering licenses to infringers of a firm's intellectual property. Survey data show that environmental antecedents concerning appropriability, i.e., patent protection and technological turbulence, and determinants regarding technology markets, i.e., transaction frequency and competitive intensity, have different effects on proactive and reactive licensing. On this basis, the article has major implications for research into technology licensing, markets for technology, and open innovation.  相似文献   

Initiating private-collective innovation: The fragility of knowledge sharing     

Simon Gächter 《Research Policy》2010,39(7):893-906

Incentives to innovate are a central element of innovation theory. In the private-investment model, innovators privately fund innovation and then use intellectual property protection mechanisms to appropriate returns from these investments. In the collective-action model, public subsidy funds public goods innovations, characterized by non-rivalry and non-exclusivity in using these innovations. Recently, these models have been compounded in the private-collective innovation model where innovators privately fund public goods innovations. Private-collective innovation is illustrated in the case of open source software development. This paper contributes to the work on this model by investigating incentives that motivate innovators to share their knowledge in an initial situation, before there is a community to support the innovation process. We use game theory to predict knowledge sharing behavior in private-collective innovation, and test these predictions in a laboratory setting. The results show that knowledge sharing is a coordination game with multiple equilibria, reflecting the fragility of knowledge sharing between innovators with conflicting interests. The experimental results demonstrate important asymmetries in the fragility of knowledge sharing and, in some situations, more knowledge sharing than theoretically predicted. A behavioral analysis suggests that knowledge sharing in private-collective innovation is not only affected by material incentives, but also by social preferences such as fairness. The results offer general insights into the relationship between incentives and knowledge sharing and contribute to a better understanding of the initiation of private-collective innovation.  相似文献

Institution initiatives and support related to faculty development of open educational resources and alternative textbooks     

Veronica McGowan 《Open Learning》2020,35(1):24-45

ABSTRACT

Evidence exists that American institutions of higher education are well-entrenched in the consideration of mechanisms for supporting the implementation of Open Educational Resources (OER) and alternative textbooks. Literature reveals that developing and implementing OER is a significant undertaking in terms of time and human resources. This study deploys content analysis of a sample of United States regionally based higher education institutional websites to determine the current state of institutional support mechanisms to implementers just embarking on the OER journey. Findings reveal that institutions have made strides in the development of faculty mini-grants and stipends with guidelines, proposal checklists, and weighting mechanisms to inform decision making. However, due to widespread language across the stratified sample emphasising award pool and individual limits, it is clear that OER funding is still seeking wider support as a permanent funded resource. Sponsorship of institutional OER initiatives seems split between institutional library functions and teaching and learning centres. Other issues, such as ownership and licensing, are significantly underdeveloped in field implementation or fall in a large continuum of practices. Recommendations of shared responsibility and use of data driven initiatives are provided that may improve institutional support of faculty OER adoption, adaption and creation.  相似文献
