Recent terrorist acts, in particular the 9-11 attacks in 2001, have created disruptions in the global economy. The short-term impact had been felt in the global tourism, airline industries, as well as the financial markets. While the global economy has recovered and is adjusting to the new global realities, the longer-term impact of heightened security risk across the world can be felt in the form of higher risk premiums in asset markets, as well as a shift of resources towards dealing with terrorism. Just as World War II had accelerated the development of nuclear energy as well as a major contributing factor in the genesis of Silicon Valley, the current war against terrorism will affect both the pace and trajectory of technology trends, as efforts are focused on developing technologies to combat terrorism. In this paper, we review the effects of the current war on terrorism in terms of its impact on the economy, the allocation of resources to R&D, and the trajectory of future R&D. 相似文献

This paper integrates the analytic hierarchy process (AHP) with scenario analysis techniques to explore the commercialization of future hydrogen fuel processor technologies. AHP is a multi-attribute decision analysis tool useful for evaluating decisions with multiple criteria and alternatives. In this paper, AHP is extended using a technique called perspective-based scenario analysis (PBSA). In PBSA, scenario analysis is conducted based on potential future decision-maker perspectives that are integrated into the AHP framework. This paper discusses this method and applies it to the evaluation of hydrogen fuel processor technologies 15–20 years hence. The results provide an added layer of insight into the opportunities and barriers for the commercialization of these technologies as well as the methodological opportunities for using AHP and PBSA as a futures tool. 相似文献

新兴技术是提高国家产业竞争力的重要载体,但是资金问题一直是制约我国新兴技术产业化的瓶颈之一。构建新兴技术产业化融资影响因素理论模型,运用DEMATEL方法,实证检验不同因素对新兴技术产业化融资的影响程度。研究表明:融资扶持政策、资金渠道可选择性、共享信息有效性等因素对新兴技术产业化融资具有显著直接影响;资金供求匹配性、融资产品创新、信息共享方式等因素易受到其它微观因素影响,对产业化融资具有显著间接影响;担保费用、配套服务综合性及配套服务专业性等因素对产业化融资同时具有显著的直接与间接影响。据此,提出新兴技术产业化融资对策建议。 相似文献

Successful innovation and diffusion of technology can be attributed to the identification of the orbit of emerging new technologies that complement or substitute for existing technologies. This dynamism resembles the co-evolution process in an ecosystem. In an ecosystem, in order to maintain sustainable development, the complex interplay between competition and cooperation, typically observed in predator-prey systems, create a sophisticated balance. Given that an ecosystem can be used as a masterpiece system, this sophisticated balance can provide suggestive ideas for identifying an optimal orbit of competitive innovations with complement or substitution dynamism.Prompted by such a sophisticated balance in an ecosystem, this paper analyzes the optimal orbit of competitive innovations and, on the basis of an application of Lotka-Volterra equations, it reviews substitution orbits of Japan's monochrome to color TV system, fixed telephones to cellular telephones, cellular telephones to mobile Internet access service, and analog to digital TV broadcasting. On the basis of substitution orbits analyses, it attempts to extract suggestions supportive to identifying an optimal policy option in a complex orbit leading to expected orbit.Key findings include policy options that are effective in controlling parameters for Lotka-Volterra equations leading to expected orbit. 相似文献

制造企业服务化过程中伴随着产品创新和服务创新,且两类创新协同演进是推动服务化进程的重要力量。当前,服务化研究大多以此为基点,探讨两类创新的关系,并且随着服务化的“数字化”特征越发明显,大多数学者从技术层面提出数字化技术对两类创新的促进作用。然而,鲜有学者考虑数字化技术对两类创新关系的影响,在一定程度上制约了数字服务化研究与实践。为此,首先通过系统回顾相关文献,分析两类创新的相互作用及其耦合困境;其次,厘清数字化技术促进两类创新的前因、过程与结果,并据此解析数字化技术增强两类创新耦合效应的作用机理;最后,提出该主题未来可拓展研究的三大方向。 相似文献

积极财政政策宏观经济效益分析——基于宏观计量模型的研究 总被引:2,自引:0,他引:2
龚刚 《数量经济技术经济研究》2006,23(12):3-13
本文通过一个宏观计量模型来研究积极财政政策的宏观经济效益。与传统模型所不同的是,我们的模型不仅考虑了需求,同时也引入了社会的供给能力。研究表明,积极财政政策的实施为我国在2003年底彻底走出通货紧缩的阴影作出了不可磨灭的贡献。而到了2002年,积极财政政策的拉动效应开始递减,这为此后逐渐淡出的积极财政政策提供了一定的依据。 相似文献

A technology assessment (TA) program was launched in Switzerland in 1991. One project in the series of pilot projects was meant to assess the impact of so-called LESIT technologies on energy consumption. (LESIT was a priority research program and a German acronym for power electronics, systems and information technology.) In this paper the institutional environment, applied methods and main results of the TA study are summarised. One of the questions that arose was whether it is reasonable to expect a high-tech engineering research program to serve any societal goals other than the more immediate technical and economic goals the research partners in university and industry are accustomed to follow. It was found that without special efforts this expectation was not realistic. Politically desirable goals are best served when enough emphasis, time, and money are given to the process of bringing together research partners from academia and industry who all have a (self-serving) interest in furthering the politically desirable goal and then support their collaboration. 相似文献
