A new bibliometric technique enables one to distinguish high emergence topical content. This technique can be applied to sets of research publication abstracts reflecting a given technical domain (here, nanotechnology) to score cutting edge research terms. The resulting high emergence terms warrant special consideration in setting R&D priorities. The researchers (individuals, organizations, or countries) whose publications address those emergent terms heavily deserve consideration as possible leaders in that technical domain. This paper studies nanotechnology research publications using the new emergence scoring in conjunction with established bibliometric publication and citation measures. Findings challenge U.S. superiority in cutting edge nanotechnology research. China shows strongest at addressing emergent nanotechnology topics, followed by the U.S., South Korea, India, and, surprisingly, Iran.  相似文献

As in other fields of science, bibliometry has become the primary method of gaging progress in nanotechnology. In the United States in the late 1990s, a period when policy makers were preparing the groundwork for what would become the National Nanotechnology Initiative (NNI), bibliometry largely replaced expert interviews, then the standard method of assessing nanotechnology. However, such analyses of this sector have tended not to account for productivity. We hope to correct this oversight by integrating economic input and output measurements calculating academic publications divided by the number of researchers, and accounting for government investment in nanotechnology. When nanotechnology journal publication is measured in these ways, the U.S. is not the leader, as has been widely assumed. Rather, it lags behind Germany, the United Kingdom, and France.  相似文献

Technology Assessment reflecting on R&D and technological trends in the area of nanotechnology and its implications is confronted with the problem that most scientific endeavours of nanotechnology can be allocated to basic research while most of the technological visions related to nanotechnology are far (> 10 years) in the future. Since technology assessment has to integrate the socio-economic context of a technical product in order to be comprehensive, in the case of nanotechnology a preparing step is necessary which connects the ongoing basic research with the visions communicated either by the scientist themselves or by the media. In this paper we propose to adapt the well known tool ‘roadmapping’ to contribute to the solution of this problem. This poses new challenges for roadmapping methodology in terms of level of aggregation and timeframe.  相似文献

Developments in nanotechnology are poised to have a pervasive effect on various industries for years to come and nanotechnology management research is beginning to appear in peer-reviewed management journals. Much of the research on this early, emergent technology is focused on issues of definition and identification of technology type. In this study, we searched the US Patents and Trademarks Office database and used an expert validation methodology to develop a sample of the first 25 years (1980–2004) of nanotechnology patenting activity. We analysed this data for early evidence that nanotechnology is a general-purpose technology (GPT) – a transformative technology characterised by its pervasiveness, improvement over time, and pattern of diffusion. Our findings indicate that nanotechnology patenting activity has been growing in intensity and relative to overall patenting activity, and that it is pervasive across industry and technology sectors. Implications of nanotechnology as a GPT are discussed.  相似文献

Mergers and acquisitions (M&As) are an important but unstudied aspect of nanotechnology's evolution. This paper uses case review and bibliometric analysis to examine 20 M&As involving acquired firms in the nanotechnology domain. The guiding proposition is that acquired firms provide complementarities to the acquiring firms. Key measures given consideration include the nature of the post-acquisition organisation, whether the pre-acquisition geographic location is retained, the purpose of the acquisitions as indicated in news releases, and the extent of similarity in research publications and patents. Differences by the country of the acquiring firm and sub-industry are noted. Within the limitations of the case study approach, the results suggest that acquired firms in the nanotechnology domain provide complementary capabilities to their acquirers.  相似文献

The purpose of this paper is to analyse, by concentration measures and metrics of heterogeneity, the evolutionary trajectories of scientific output in nanotechnology research across worldwide economic players. The results show that the concentration in nanotechnology research has been reducing over time and space. In particular, the pattern of nanotechnology research has been spreading among different scientific domains and pathways, generating new technological paradigms mainly in chemistry, medicine and engineering research fields. This scientific analysis is important in order to explore the current knowledge growth and technological trajectories in nanotechnology research that may support future patterns of technological innovation.  相似文献

Text mining was used to extract technical intelligence from the open source global nanotechnology and nanoscience research literature (SCI/SSCI databases). Identified were: (1) the nanotechnology/nanoscience research literature infrastructure (prolific authors, key journals/institutions/countries, most cited authors/journals/documents); (2) the technical structure (pervasive technical thrusts and their inter-relationships); (3) nanotechnology instruments and their relationships; (4) potential nanotechnology applications, (5) potential health impacts and applications; and (6) seminal nanotechnology literature. Our results are summarized in this paper.  相似文献

Much of the initial commentary on nanotechnology assumed, implicitly or explicitly, that nanotechnology represented a radical discontinuity from existing science and technology. The birth of the nanotechnology debate was marked by the differences of opinion as to whether the technology's outcomes would be positive or negative. The authors trace the journey from this polarized debate to the current discussion of nanotechnology, finding that the latter is still conducted in the parameters set by the initial utopian and dystopian extremes. Yet the discussion now focuses on defining the technology and identifying the social and ethical issues, which are often reduced to the potential risks of toxicity and the need for public engagement. The authors argue that nanotechnology is erroneously treated as homogeneous and is under-analysed; it is the very diversity and transdisciplinary nature of nanotechnology that makes it distinctive and interesting to social science enquiry. In this way, it may yet be prototypical of Gibbons et al. 's 'Mode 2' science. The focus of social science research should be less on the implications of nanotechnology, and more on its creation, the processes through which it develops and the alternative perspectives underlying this. The authors conclude by outlining core elements of a social science agenda for nanotechnology.  相似文献

This Research Note updates our 2006 and 2009 China/USA nanotechnology and nanoscience (NN) research output comparisons.A 2009 comparison of China/USA research publication outputs showed that China is about to overtake the USA in NN research output. As predicted by the extrapolated 2009 curve, China has passed USA in NN research publication output. This transition occurred in the 2008/2009 time frame, and if the 2011 results (taken at mid-2011) hold for the full year, will become quite pronounced (~ 20%).When specific sub-disciplines are examined, the differences between China and USA become more pronounced. For example, the 2009 paper presented the time trend for China/USA publications in nanocomposites, an important sub-discipline of NN. The updated nanocomposites curve has increased about twice the rate of the overall NN curve, and shows no sign of abating.The USA papers lead in the numbers of citations by all metrics considered, but the Chinese papers are showing significant improvement with time. Overall, the Chinese papers are cited very modestly, but there is a core of 'heavy hitters' that appears to be increasing substantially with time, and is increasingly making its presence known in the higher Impact Factor journals.  相似文献

This paper provides the first empirical information about barriers related to the diffusion of nanotechnology, a general purpose technology. Our analysis is based on the findings from a state-wide survey of companies in North Carolina, USA. We find that the primary barrier is lack of access to early-stage capital, and the extent of this barrier is greater when the company contributes to the value chain for nanotechnology through R&D as opposed to through products or services. Another barrier is lack of access to university equipment and facilities, a problem greater in companies involved in nanotechnology research. From a policy perspective, our analysis suggests that state governments could act as venture capitalists to overcome market failure in the capital market, and that states could provide incentives to universities through public/private centers of excellence for sharing capital equipment and facilities with nanotechnology companies.  相似文献

ABSTRACT

With the increasing emphasis of the government on the importance of Party organisations in China’s state-owned enterprises (SOEs), we need to pay more attention to its role in the operation of enterprises. As the research on board of directors emphasises the central position of the chairman, this paper focuses on the top leader of the Party organisation, namely the Party Committee Secretary. Based on upper echelon theory, this paper proposes the relationship between the technology background of a Party Committee Secretary and firm’s innovation efficiency, and how this relationship is moderated by position duality and environment dynamism. Using the data of China’s listed SOEs which issue A-shares in Shenzhen and Shanghai stock exchanges from 2014 to 2016 and operate in the manufacturing industry, the main effect and moderating effects are tested. We find that the existence of a Party Committee Secretary with technology background positively affects the SOE’s innovation efficiency. In addition, this relationship is strengthened by environment dynamism. Our conclusions not only enrich literature about upper echelon theory and determinants of firm’s innovation, but also are helpful for improving corporate governance in developing countries.  相似文献

This paper presents results from a pilot study of small and medium-sized enterprises (SMEs) based on a web-scraping and content analysis of current and archived nanotechnology enterprise websites. We use this approach to explore nanotechnology SMEs transitions from discovery to commercialisation and understand how transitions vary by SME characteristics, technology and market sectors. Our findings suggest that although the idealised linear innovation model is present, important instances of divergence exist. Cluster analysis uncovered sectoral differences but even more distinctions based on the age, funding source, and research intensity.  相似文献
