Although it is evident that technology is becoming increasingly globalized, resulting in the expansion of R&D internationalization by firms, despite this discernible trend, the substantial body of literature in this area is based mainly on the experience of the developed country. This paper aims to contribute to the understanding of this issue by examining the R&D internationalization of a newly-industrializing country, Taiwan being a prime example, and its connection with the global production network. We begin with an examination of the literature on R&D internationalization and globalization, based upon which we propose a conceptual framework adapted from Dunning’s eclectic paradigm. In doing so, we set out to develop arguments based not only on the reasons why cross-strait R&D internationalization may be undertaken by Taiwanese information technology (IT) firms, but also the likely patterns of their R&D portfolios across the strait. Drawing on an original questionnaire survey and firm-level interviews, the paper presents and discusses empirical data on the cross-strait R&D deployment of Taiwanese IT firms. It then goes a stage further, using the ‘smiling curve’, to put forward a ‘holistic’ view of the cross-border innovation network in the IT hardware industry, in order to determine what cross-strait R&D internationalization means to the global production network. 相似文献

粮食综合生产能力与国家粮食安全 总被引:2,自引:0,他引:2
提高粮食综合生产能力,是确保国家粮食安全的重要战略性举措。随着城市化和工业化的快速推进,耕地、水资源、农业基础设施、种粮比较收益等方面的弊端相继凸显,不仅影响了粮食综合生产能力的进一步提升,甚至还可能危及到未来国家粮食的安全。为了实现国家粮食的长治久安,必须破除现存的瓶颈,构建粮食综合生产能力稳步提升的长效机制。 相似文献

This paper presents a game of industrialisation, based on a paper airplane, that mimics real world production ramp-up and blends classical engineering courses together. It is based on a low cost product so that it can be mass produced. The game targets graduate students and practitioners in engineering fields. For students, it offers an experiment in which methods learned in separate courses can be applied. For practitioners, it affords an opportunity to engage in reflexive practices related to industrialisation. Both students and practitioners are able to experience integrated management, required by industrialisation, in a controlled environment: the laboratory. 相似文献
