Recent years have seen growing academic interest in the concept of induced diffusion as efforts to address concerns about energy security and climate change have intensified. Research on induced diffusion explores whether policy tools or interventions can incentivise the diffusion of innovations. This body of literature has explored the effectiveness and efficiency of various policy interventions and as such has been mainly concerned with the determinants of diffusion. This paper is, by way of contrast, concerned with the patterns of diffusion when diffusion is induced. Drawing on the Bass and Davies models of innovation diffusion we develop a number of propositions that suggest that the patterns of diffusion are different when policy plays a role in the diffusion process. These propositions are then econometrically tested in the context of the international diffusion of wind energy in 25 OECD countries. We find that, as predicted, without effective and strong policy interventions, countries will have conventional logistic diffusion with very similar speeds of diffusion. However, as expected the patterns of diffusion take on a different functional form (Bass curve) when there is a strong policy inducement. We conclude by discussing the implications and limitations of these results and suggesting avenues for further research. 相似文献

Context matters: How existing sectors and competing technologies affect the prospects of the Swiss Bio-SNG innovation system 总被引:1,自引:0,他引:1
Steffen WirthAuthor VitaeJochen MarkardAuthor Vitae 《Technological Forecasting and Social Change》2011,78(4):635-649
Emerging technological fields are affected by developments in their broader context. This article proposes a differentiation of context structures as a crucial step in the analysis of technological innovation systems. A thorough context analysis, so the argument, is essential for understanding the pace and direction of technology development and the prospects of an emerging technological innovation system. Empirical insights are provided for Bio-SNG, a technology in an early stage of development. The article discusses the conditions under which actors from different sectors (forestry, wood industry, and energy supply) may play a role in the emerging field. It is shown that Bio-SNG is likely to become a victim of the recent boom in wood-to-energy technologies that has favored investments in more mature but technologically inferior alternatives. The case provides lessons for policy making as it highlights how effective support schemes might foster a lock-in into technologies that are readily available. 相似文献

Technology evaluation, as an organizational process, is the essential ability to comprehend the values of technologies very soon after they emerge. Meanwhile, the technology evaluation process is inevitably influenced by the firm's industrial context, such as its technological trajectory. This study defines technology evaluation strategy in terms of the processes, methods, and participants involved, and uses this definition as a taxonomy to explore different types of technology evaluation strategies. A survey on the technological industries is conducted to explore types of technology evaluation strategies and their relationships with the advantages of different types of innovation under the effects of different technological trajectories. The survey identifies four types of technology evaluation strategies, namely, those of the flexible executive strategist, the emergent executive intuitionist, the deliberate quantitative strategist, and the deliberate consensual strategist, are identified. This study has found that certain types of technology evaluation strategies have better innovation performances than the others. The patterns of technological trajectories are also found to influence a firm's technology evaluation strategy and the advantages of certain types of innovations. The established explanations of the relationships among the technological trajectory, innovation type, and technology evaluation strategies may guide technology businesses to develop a better technology evaluation capability. The theoretical framework developed in this research enriches the strategic management literature with a new taxonomy for technology evaluation strategies. 相似文献

Moore's Law has created a popular perception of exponential progress in information technology. But is the progress of IT really exponential? In this paper we examine long time series of data documenting progress in information technology gathered by [1]. We analyze six different historical trends of progress for several technologies grouped into the following three functional tasks: information storage, information transportation (bandwidth), and information transformation (speed of computation). Five of the six datasets extend back to the nineteenth century. We perform statistical analyses and show that in all six cases one can reject the exponential hypothesis at statistically significant levels. In contrast, one cannot reject the hypothesis of superexponential growth with decreasing doubling times. This raises questions about whether past trends in the improvement of information technology are sustainable. 相似文献

The objective of this research work is to study the progress of research on technological uncertainties, social uncertainties and emerging markets and outline and identify the key disciplines, journals, articles and authors. For this the author studied the existing literature from the various fields in which technological uncertainties, social uncertainties and emerging markets research work have been published using ISI Web of Knowledge database. The paper finds that there is increasing research work on technological uncertainties, social uncertainties and emerging markets and the bibliographical search resulted in ninety-one documents written by one-hundred-sixty-one authors in eighty-four journals in seventy-two disciplines. The five major disciplines and their underlying journals are business and economics, agriculture, psychology, public administration, and environmental sciences and ecology accounting for majority of publications. In journals the most prolific, measured by number of articles published are Harvard Business Review, Social Science and Medicine, World Development, and Higher Education; and most influential, measured by the global citation received, are Harvard Business Review, Social Science and Medicine and Sociological Review. The top 10% of the journals are responsible for 23% of all publications but 85% of all global citations received. This highlights that despite the high, diverse and increasing number of journals; only few are dominating and shaping the research arena of technological uncertainties, social uncertainties and emerging markets. Further, in the ten most cited articles, no author appears more than once. 相似文献

Industry changes in technology and complementary assets and the creation of high-growth firms 总被引:1,自引:0,他引:1
This study uses employment data to examine why some industries host more new high-growth firms than others. Using a unique data base of 201 industries over a 15-year period, we find that increases in the proportion of employment of scientists and engineers in industries are positively associated with counts of fast-growing new firms; however, we do not detect a relationship between fluctuations in the proportion of employment in sales and production occupations and counts of fast-growing new firms. The findings suggest that technological innovation is an important determinant of entrepreneurial opportunity. Further, they suggest that private new firms are an important means of organizing commercial innovation and that new firms may be less constrained by complementary assets than has been previously understood. 相似文献

关于国际技术扩散对我国贸易竞争优势影响的思考 总被引:1,自引:0,他引:1
在经济全球化的进程中,一国的技术进步不仅依赖于本国的创新,而且还需要充分利用他国的先进技术资源,并通过各种渠道的技术扩散和技术外溢来促进本国的技术进步与经济增长,从而在国际市场上提升本国的贸易竞争优势。结合我国现状从宏观和微观两个角度分析了国际技术扩散对我国贸易竞争优势的影响。 相似文献

国际技术扩散测度的结果,直接影响着对经济研究中一些最根本最重要问题的回答。如何对国际技术扩散进行准确度量,是到目前为止理论界尚未解决的难题。本文系统梳理了国外学者在国际技术扩散测度领域的理论和实证成果,发现由于技术扩散的无形性,测度只能使用相关回归等间接方法,因此在选择测度方法时,必须明确模型的经济意义和理论基础。在实证方面,分析了投入、产出和技术效应三类常用的国际技术扩散测度指标各自的优缺点,国际贸易、FDI及技术转让三种扩散渠道下国际技术扩散测度的方法和结论。最后,指出了这一研究领域中尚需深入研究的问题。 相似文献

面对人才计划是激励了科技人才,还是诱发了科技人才急功近利、心浮气躁的争议,本文系统梳理了人才计划选育人才特点和实践过程中存在的功能异化问题,构建了包含成就动机的科技人才激励理论模型分析框架,并使用全国科技工作者调查数据和倾向得分匹配方法,实证检验人才计划激励高层次科技人才成就动机的净效应。结果表明:(1)人才计划的特点是强调以人为本,旨在培养和提高科技人才的创新研究能力,鼓励人才自由探索和根本创新,但实施过程中存在政策工具的过度使用、薪酬待遇和资源的过度倾斜等问题;(2)适度科研经费支持有助于强化科技人才的成就动机,而过度强调绩效激励则可能产生挤出效应;(3)入选人才计划对高层次科技人才成就动机的激发作用是显著的,在继续推进人才计划支持方式的同时应正视弊端、系统谋划。 相似文献
