国家创新系统的效率评价研究   总被引:2,自引:0,他引:2       下载免费PDF全文
数据包络分析是一种评价决策单元相对效率的有效工具,已经被广泛运用于对国家或者区域创新系统的效率评价之中。然而,之前的研究都将国家创新系统视为一种简单系统,因此无法得到科学的评价结果。本文将国家创新系统视为一种链形系统,运用链形系统DEA方法对其进行效率评价,评价结果显示了该方法的合理性。  相似文献

The dynamics of national innovation systems (NISs) are a source of considerable academic and policy interest, especially when to address new competitive challenges they involve changing institutions and relationships within successful systems. This paper examines the case of Taiwan which is embarking on a new phase in its approach to building its national innovative capacity through creating the infrastructure for a biotechnology industry. By examining the process and mechanisms by which new biotechnology innovation networks are being created, and contrasting their development with existing networks, we analyse the dynamics of Taiwan's NIS. The paper reviews the prospects for this new phase in Taiwan's transition from ‘imitation’ to ‘innovation’. The paper aims to add to the understanding of how innovation systems evolve. It is concerned with the contributors, processes and challenges of NIS evolution and the form and meaning of its dynamic changes.  相似文献

创新主体的创新效率区域比较研究   总被引:1,自引:0,他引:1  
通过构建旨在评价中国三大创新主体(企业、高校和科研院所)的创新效率及其影响因素的随机前沿模型,对1999-2008年中国30个省份的面板数据进行实证研究,发现三大主体的创新活动均对创新资源的依赖较大,创新效率值均小于1,其中企业的创新效率值最低。技术非效率因素显著存在,其中政府资助和创新主体间的联系对创新主体的作用截然不同。同时,在以创新效率的聚类分区中,企业创新高效区的省份相当少,高校创新高效区和科研院所创新高效区的省份较多,但又有所差异。区域创新主体间的效率差异,以及区域之间的差别,显示出了区域创新的动力源泉和发展特点。  相似文献

 虚拟科技创新团队的科研合作效率是团队管理者普遍关注的问题。运用DEA模型的视窗分析和相关分析,将经费设施、人力资本、制度保障作为投入指标,合作深度、合作广度、合作提高为产出指标,以16个虚拟科技创新团队2004-2009年的调研数据为样本,对团队科研合作效率变化趋势、稳定性和影响因素进行研究。结果表明,随着合作时间的延长,团队科研合作的总体效率(TE)、纯技术效率(PE)具有波动上升的趋势,规模效率(SE)不存在明显的规律性,各团队效率稳定性存在较大差异;要提高SE应该从提高经费设施的相对产出入手,要提高PE应该从提高人力资本的相对产出入手,制度保障对TE、PE和SE都有影响,团队应在完善制度的基础上进行“有序扩张”。  相似文献

Public Research Institutes (PRIs) were established for many reasons, such as to promote defence related research and health related research. Helping domestic industries remains one of the important missions for public research institutes even when the countries have industrialized and firms’ technological capabilities are high. PRIs aim to upgrade existing industries, especially SMEs, as well as spearheading new ones. They can conduct research to solve today’s problems of existing industries and those of next generation technologies which might lead to creation of new industries. Moreover, relationship between PRIs and firms and non-firm actors like universities became more intense, open, horizontal, international, and longer term. To reduce risk and uncertainty inherent in research mentioned above, intermediary roles of PRIs are increasingly important. The emphasis and the ways PRIs help industry change over time and vary across countries as they are integral part of national innovation systems. This makes generalization difficult, but the experiences of five leading PRIs in Germany, Taiwan, Japan, Australia, and the US shows that, the balances between contract research vs. longer term research with own initiative, mobility of researchers vs. retaining core researchers, and competitive grants and funds from industry vs. block grants from government are important to keep PRIs relevant to industry needs and maintain research standards. The governance of PRIs is of particular importance to maintain proper balances.  相似文献

Internationalization of innovation systems: A survey of the literature   总被引:4,自引:0,他引:4  
While there is a large literature on the internationalization of economic activity (including R&D) at the corporate level, there are not many studies of the degree of internationalization of innovation systems. The few studies that exist show that national innovation systems are becoming internationalized, even if the institutions that support them remain country-specific. To the extent that the far more numerous studies of internationalization of corporate R&D discuss innovation systems at all, they point to the continued importance of national institutions to support innovative activity, even though that activity is itself becoming increasingly internationalized.  相似文献

This paper, using Thailand as a case study, aims at understanding the national innovation system (NIS) in developing countries which are less successful in technological catching-up. In contrast to developed countries, the development level of Thailand’s NIS does not link to its economic structural development level. As Thailand moves from agricultural to an increasingly industrial economy, its NIS remains weak and fragmented. The mismatch between the two affected Thailand’s competitiveness and partially contributed to the recent economic crisis. Studies of NIS in countries like Thailand should focus on factors contributing to the long-running perpetuation of weak and fragmented NIS.  相似文献

We investigate the impacts of political instability and pro-business market reforms on national systems of innovation (NSI) across a range of developing and developed countries. Evidence suggests that national systems of innovation are most likely to flourish in developed, politically stable countries and less likely to prosper in historically unstable countries. While research has shown that pro-business market reforms can be a valuable policy instrument to boost economic development in less developed countries, the extent to which these reforms affect a country's innovativeness has been neglected in the literature. In particular, the degree to which pro-business market reforms may compensate for political instability when it comes to fostering national systems of innovation remains under-researched. Our findings support established arguments concerning the strong influence of political instability on inputs to national innovation systems. We find, however, mixed effects for pro-business market reforms. While results indicate a negative direct influence on NSI, they consistently show a strong moderating effect that counterbalances the negative impact of political instability, especially in those developing country environments where science and technology are lagging. These results provide important implications for policymakers as well as for our understanding of emerging and transition economies and national technological capability.  相似文献

Science, technology and innovation (STI) policy is shaped by persistent framings that arise from historical context. Two established frames are identified as co-existing and dominant in contemporary innovation policy discussions. The first frame is identified as beginning with a Post-World War II institutionalisation of government support for science and R&D with the presumption that this would contribute to growth and address market failure in private provision of new knowledge. The second frame emerged in the 1980s globalising world and its emphasis on competitiveness which is shaped by the national systems of innovation for knowledge creation and commercialisation. STI policy focuses on building links, clusters and networks, and on stimulating learning between elements in the systems, and enabling entrepreneurship. A third frame linked to contemporary social and environmental challenges such as the Sustainable Development Goals and calling for transformative change is identified and distinguished from the two earlier frames. Transformation refers to socio-technical system change as conceptualised in the sustainability transitions literature. The nature of this third framing is examined with the aim of identifying its key features and its potential for provoking a re-examination of the earlier two frames. One key feature is its focus on experimentation, and the argument that the Global South does not need to play catch-up to follow the transformation model of the Global North. It is argued that all three frames are relevant for policymaking, but exploring options for transformative innovation policy should be a priority.  相似文献

The importance of innovation in healthcare has increased within the last decades as challenges, like rising costs and an aging demographic, have to be solved. The degree of innovativeness in healthcare is strongly influenced by the National Health Innovation System, which as a sectoral innovation system encompasses a wide variety of actors and related knowledge. Despite the highly practical relevance of the topic, there are only a few studies that analyze innovation in healthcare on a national level. Thus, this study is a starting point and, building on the theoretical framework of national innovation systems, answers the following questions: “Can countries be grouped by their innovation output in healthcare and do those groups differ in factors describing the healthcare system? Do countries with strong national innovation systems also have strong national health innovation systems and vice versa?” We compare the healthcare innovation output of 30 OECD countries using a multi-indicator approach and categorize them into four distinct groups using cluster analysis. The cluster consisting of the Scandinavian countries, the Netherlands and Switzerland shows the highest innovation output measured in knowledge production and knowledge commercialization. Surprisingly, these countries, with the exception of Switzerland, only rank in the medium group when considering the entire national innovation system. Policymakers and researchers might be particularly interested in studying the healthcare systems of these countries.  相似文献

Technological innovation systems and the multi-level framework are closely related concepts for the study of far-reaching technological change. They draw on common theoretical roots and analyze similar empirical phenomena. However, they have developed rather independent research strands over the past few years. The paper reviews the state of the art of both concepts and explores commonalities as well as differences. Against this background, we outline first elements of a path towards an integrated framework that combines the strengths of the two approaches and allows providing a better understanding of radical innovation processes and socio-technical transformations.  相似文献

This study considers the role of national differences, derived from structural characteristics in each country, and how they impact on companies’ innovation. To do this we include in a firm-level empirical model of innovation traditional factors impacting on innovation, and measure any differences in these determinants between two countries: the UK (comprising more advanced regions) and Spain (which belongs to the “follower” groups of countries in Europe). Using the European Community Innovation Surveys (CIS4), we select two samples comprising private manufacturing firms and estimate a two-step Heckman model to explain firms’ innovation. Our results suggest that Spanish firms are at a different stage, with Spain lagging behind the UK in terms of being able to benefit from R&D. Thus in Spain, we find that public support is more important in promoting innovation activities; whereas linkages with international markets are more important for companies in the UK. Based on our results, we would argue that in order to reduce the technological gap between these two countries regional policies to promote innovation in Spain should concentrate more on the promotion of market relationships between co-located firms; while a greater exposure to internationalisation would benefit both countries.  相似文献
