隐形税收机制瓦解后,储蓄动员型的金融发展模式取代了财政投资的主导地位,通过金融支持政策为公有经济部门融资,支撑了经济的高速增长。然而,随着市场约束机制的变化,金融支持政策的收益逐渐下降,成本却在递增。本文认为储蓄动员型的金融支持政策在一定阶段促进了经济的发展,但是也伴随着一系列经济发展的成本,比如降低了资本配置效率,过度投资产生的宏观经济成本和经济持续增长的外部风险加大等。因此,中国金融体制应深化改革,提高金融体系的资本配置效率,促进技术进步和生产效率的改进。同时,通过发展消费信贷和商业保险,减少信贷约束和不确定性,推动消费型经济的增长。  相似文献

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

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

运用空间数据分析方法,检验产军协同、政府科技支持与技术创新效率在我国省域间的分布格局。研究表明,三者均存在显著的正向空间相关性,即正向空间溢出效应,并且在不同地区形成局部空间集聚,存在高低非均衡的“俱乐部”现象。基于空间误差模型和空间滞后模型,实证检验产军协同、政府科技支持对技术创新效率的影响。结果发现,从全国和分地区看,产军协同、政府科技支持均能够显著促进技术创新效率提升,并且二者存在显著的交互作用,能够发挥彼此间的互补效应,进一步促进技术创新效率提升;不同地区产军协同、政府科技支持对技术创新效率的影响程度存在较大差异,西部地区产军协同、政府科技支持对技术创新效率的促进作用比东部和中部地区显著。  相似文献

以创业板企业数据为样本,使用Logit模型及工具变量法,研究不同区域环境下政府背景风险投资对企业创新的事前甄选与事后培育作用,并对其机制进行探讨。结果表明:①经济区域对政府背景风险投资行为影响有限,与非核心发达地区相比,金融发达地区的政府背景风险投资对企业技术创新没有表现出差异性甄选行为,但却有更好的事后培育作用,而且这种培育作用会随着地区投资环境优化而增强;②行政区域对政府背景风险投资行为影响显著,与异省投资相比,本省政府背景风险投资对技术创新的事前甄选具有显著优势,但对被投企业后续创新投入产生了一定的负面作用,这种作用会因政府背景风险投资占有董事会席位而加大。  相似文献
