新型工业化与传统工业化具有截然不同的发展思维,新型工业化与传统工业化形成的剧烈反差将激发民营企业的创新动力。民营经济的科技创新凝结了以科技为核心的生产要素,开拓了一条向技术、人才、管理争效益的路径。顺应新型工业化与民营经济科技创新的互动机理,需要分析互动的环境因素、夯实互动基础以激活互动效应。 相似文献

Control of SO2 emissions from power plants: A case of induced technological innovation in the U.S. 总被引:1,自引:0,他引:1
This paper investigates how the details of government actions induce innovation—the overlapping activities of invention, adoption and diffusion, and learning by doing—in “environmental technology,” products and processes that either control pollutant emissions or prevent emissions altogether. It applies multiple quantitative and qualitative measures of innovation to a case subject to several “technology-push” and “demand-pull” instruments: sulfur dioxide control technology for power plants. The study employs analyses of public R&D funding, patents, expert interviews, learning curves, conference proceedings, and experience curves. Results indicate that: regulation and the anticipation of regulation stimulate invention; technology-push instruments appear to be less effective at prompting invention than demand-pull instruments; and regulatory stringency focuses inventive activity along certain technology pathways. Increased diffusion of the technology results in significant and predictable operating cost reductions in existing systems, as well as notable efficiency improvements and capital cost reductions in new systems. Government plays an important role in fostering knowledge transfer via technical conferences, as well as affecting the pattern of collaborative relationships within the technical research community via regulatory changes that affect the market for the technology. Finally, the case provides little evidence for the claim that cap-and-trade instruments induce innovation more effectively than other instruments. 相似文献

This article examines spillover effects from inward investment on domestic firm growth in the case of a developed host country. The emphasis is placed on the role of the technological gap between domestic and foreign firms in identifying the importance of technology diffusion from the presence of multinationals. An augmented production function is employed to account for technological, financial and market structure effects. Based on a sample of 2589 manufacturing firms operating in Greece between 1992 and 1997, the analysis provides evidence that the significance of spillovers varies with the relative technological position of domestic firms and is higher in the middle and upper quantiles of the growth distribution. It was estimated that a unit increase in the foreign presence in Greek industry raises output growth by 7% on average, in a five‐year period, after controlling for technological differences among firms. This result is consistent with the ‘absorptive capacity’ hypothesis that the technological capability of the host country relates positively to FDI spillover benefits. 相似文献

When a new technology is introduced in the market, this technology generally follows an S-shaped curve, especially if measured on a relative (market share) basis. Marchetti and Nakicenovic and Norton and Bass have modeled the multivariant case of various technologies introduced at different times. A new, simple and flexible model has been proposed based on potential penetration. Potential penetration is penetration on the assumption that no other new technology will enter the market. In a stable competitive environment, potential penetration curves are typically positively sloped S-curves. The new model gives a good fit in markets with a limited number of competitors, which are capable of totally cannibalizing previous generations of technologies. It also fits well with markets with many competitors in a competitive equilibrium situation. Examples are the Dynamic Random Access Memory chips (DRAMs), fiber and energy market. The new model features fewer variables compared with existing models and can readily be adapted to technological processes with time varying parameters, which is particularly important in volatile competitive markets. 相似文献

If economists of technical change dealt with the public research/industry interface, the literature lacks empirical contributions. The present paper is clearly empirical. It investigates the efficiency of the relationships between public research institutions and industry from the point of view of the firm looking for solutions to its problems. The empirical work is based on the study of 32 cases of partnerships in France. It suggests that the efficiency of the interface depends on the context (nature of innovations, public research skills needed, duration of relationships, technological strategies of firms) and on the strategies of public research institutions (organizational linkages adopted). Four hypotheses are examined to test these efficiency conditions. 相似文献

This paper aims to study those firms which have similar characteristics at the beginning of time. The objective is to observe the relation that exists between technological evolution, firms' performances and economic instability. This is done using an adaptation of the Nelson and Winter model, in order to show the possibility of various growth trajectories, and also to underline the heterogeneity of the firms. This heterogeneity corresponds to a period of economic instability, and itself only exists as a result of the specific nature of the technological trend. The theoretical interest lies in using the structures/performances relation, by according a central place to innovation. 相似文献

以治理目标为导向的结果有效作为评价重点,依照科学社会学中的科学二分法理论,结合典型文献构建具体评价指标体系,并对其进行检验与实证分析。主要结论如下:第一,科技社团治理目标的实现程度正向显著影响组织社会影响力与满意度水平;第二,当前我国科技社团总体治理有效性水平处于起步阶段,科技传播能力较强,但科技服务能力明显偏弱,且学会之间存在分化现象。其中,医科类较好,交叉学科则表现欠佳;第三,我国科技社团治理改革内在驱动力不足,政策效用与行政干预现象较明显。事实上,行政干预力量最弱的科技社团,其治理有效性水平反而最高。当前,治理转型的突破口集中在挂靠到事业单位的科技社团。 相似文献

循环经济的技术经济范式与政策研究 总被引:19,自引:0,他引:19
本文对循环经济技术经济范式的概念进行了定义,对其经济学特征进行了分析,并在此基础上指出,发展循环经济必须进行技术经济范式创新。通过对循环经济内涵的分析,提出了循环经济技术体系是传统技术范式的纵向延伸和横向拓展的观点,据此探讨了循环经济技术创新的内容。在对循环经济技术体系研究的基础上,提出了把循环经济技术开发与高技术研究开发一样纳入国家科技发展战略的观点,探讨了促进循环经济技术创新政策体系。 相似文献
