以创新和扩散为导向的集群经济效益已成为产业集群的竞争优势所在。基于时间和空间距离因素,构建了产业集群内的技术创新空间扩散模型,应用数据仿真实验,分析了在集群内进行技术创新空间扩散的动态过程,探讨了模型参数变化对技术创新扩散的影响,并着重分析了空间距离对技术创新扩散的影响。结果表明,产业集群内的技术创新扩散是典型的时空统一扩散过程,空间距离会阻碍技术创新的扩散,而且集群内采用技术创新的企业数量与距离因素呈负指数关系,为客观地预测和控制产业集群内时空统一的技术创新扩散过程提供了理论依据。  相似文献

技术多样性是企业创新能力的重要表征,但现有研究对于技术多样性与创新扩散的关系存在争议。对此,区分相关和不相关技术多样性对创新扩散的异质性影响,并检验实质性社会责任信息披露作为一种信号传递机制对上述关系的调节作用。基于2008—2017年中国研发密集型上市企业数据进行实证分析,结果发现:相关技术多样性能够积极影响创新扩散;不相关技术多样性对创新扩散的影响存在滞后效应;实质性社会责任信息披露正向调节不相关技术多样性与创新扩散的关系。结论丰富了创新扩散理论与实证研究,可为企业创新实践提供决策依据。  相似文献

Future disruptive, pervasive technologies will have important consequences for industrial structure, economic growth and the environment. Drawing on theories of technological diffusion, industrial evolution and long-term technological change this paper explores the effect of the development and diffusion of two future pervasive technologies on five industrial sectors in three regions during the 21st century in terms of their effect on economic structural change. Through semi-structured interviews with over 100 experts in the two technologies, the paper quantifies the effects of future biotechnologies and nanotechnologies on the industrial structure of the EU, USA and China in 2020 and 2050. The paper finds that as a result of the development and diffusion of future biotechnologies and nanotechnologies, some industries grow whilst others decline and some new ones emerge. The evidence suggests that the effect is different across countries and time; whereas the experts commonly believe that effect of the technologies on the industrial structure of the EU and US is likely to be similar, the effect in China is considered to be less by 2020 but the same as in the EU and US by 2050. This finding has important implications for the location of production, economic growth and energy demand in the future.  相似文献

In this paper, I model technological change as an evolutionary process of generation and selection of economic activities in a highly path-dependent fashion. There are two key features of our approach. The first is that economic activities are conceived as points of a directed graph and endowed with a corresponding notion of technological distance which determines both the probability of invention of any new activity and the cost of learning it. The second feature is that agents are assumed rational and taken to choose optimally from among the available activities, given the status quo and the associated learning costs. In such a context, we focus on two economies that start off technologically close and evolve side by side with some extent of technological diffusion across them. It is shown that alternative assumptions on the speed of diffusion may have drastically different implications for the evolution of the process. I then argue that this theoretical analysis helps provide some insight on existing empirical evidence; in particular, on the conditions under which relative stagnation or technological catch-up may arise and become consolidated among different economies.  相似文献

This paper considers the diffusion of British technology to the Continent, especially France and Prussia, during the industrial revolution. Particular attention is paid to the various transmission mechanisms and to differences in the speed of diffusion. It is shown that the economic growth of a country and its absorption of foreign technology tends to follow a logistic curve. This suggests that linear and purely economic explanations of technological transmission may be inadequate.  相似文献

Climate policy choices are influenced by the economics literature which analyses the costs and benefits of alternative strategies for climate action. This literature, in turn, rests on a series of choices about: the values and assumptions underlying the economic analysis; the methodologies for treating dynamics, technological change, risk and uncertainty; and the assumed interactions between economic systems, society and the environment, including institutional constraints on climate policy. We identify and discuss such critical issues, pushing at the boundaries of current climate economics research. New thinking in this area is gathering pace in response to the limitations of traditional economic approaches, and their assumptions on economic behaviour, ecological properties, and socio-technical responses. We place a particular emphasis on the role of induced technological change and institutional setups in shaping cost-effective climate action that also promotes economic development and the alleviation of poverty.  相似文献

This article identifies and articulates the foundations of the theoretical approach of the new book ‘Soft innovation: Economics, product aesthetics and the creative industries’ by Professor Paul Stoneman. This book is likely to open a new research area within the economics of innovation. The source of economic growth and prosperity is technological change and the economics of innovation to date has mainly focused on technological approaches to innovation. However, the development of the technological base of product and process can explain only a part of economic growth as soft innovation represents a relevant additional source of economic development that has received little attention so far. The source of a unified economic approach for soft innovation relies on Lancaster's theory of consumer behaviour coupled with the variety approach, innovation in services and the economics of knowledge. It appears as though industry structures favouring the successive emergence of new variants are characterised by soft innovations.  相似文献

This paper identifies the role of new capital goods as the main external source of innovation for supplier dominated firms belonging to traditional consumer good industries. After a brief survey on the role of inter-industry technology flows, the results of a field study are presented concerning the amount of technological change embodied in the new machinery acquired during the 1980s by a sample of Italian manufacturing firms producing traditional consumer goods. We show that industries and firms differ in the quality of technological change embodied in (or allowed by) new capital goods, and that such differences depend on industry-specific and firm-specific factors. The former primarily refer to product characteristics, the latter mainly to the age and the affiliation of the firm with an industrial group. The final section contains some policy suggestions for fostering the diffusion of new machinery (embodying technological change) among small firms and traditional industries.  相似文献

Linking technological innovation with high-quality economic development is a complex process. So far, there has been little academic research on the mechanism and internal law of technological innovation related to high quality economic development. After streamlining the research context of technological innovation in the deductive development of economic growth theory, this paper summarizes and extracts the core connotation of high-quality economic development from the concept of high-quality development and at micro, meso and macro dimensions. The internal law of technological innovation promoting high-quality economic development is revealed from six aspects, including total factor productivity, supply of high-quality products and services, industrial structure upgrading, consumption structure upgrading, resources and environment, and promoting social equity. This paper then puts forward policy recommendations for technological innovation promoting high-quality economic development at micro, meso and macro dimensions. Microscopically, organizations including R&D enterprises, universities and research institutes should have their creativity enhanced; mesoscopically, the levels of industrial chain, value chain and regional technological innovation growth pole should be improved; and macroscopically, China should raise its overall technology competitiveness in the world for high-quality economic development driven by technological innovation. This paper proposes six issues on technological innovation related to high-quality development that deserve in-depth discussion, including identifying the standards and boundaries of innovation, capturing the orientation of technological innovation, and raising the rate of transforming technological innovation achievements, etc.  相似文献

This article discuss in a tentative way what determines the effect of technological discontinuities on the competitive position. of companies within an industry. Three cases of technological change are anahzed: the change from manual to romputer numericalb controlled metal cutting machine tools, the change from stand-alone machine tools to flexible manufacturing systems; and the change from non-cellular to cellular mobile telephony It is argued that the character of technological discontinuity affects market shares, by altering the barriers to entry and mobility, and by being more or less in accordance with the different firms' vision about the future, implying variations in the time needed to detect and accept the new threat or opportunity. A technological discontinuity that includes a new threat or opportunig. A technological discontinuip that involues a new generic technology which substitutes for rather than adds to the previous technology base is seen as being most disruptive. The time actualb available for detecting the need to change and to act is limited by the market growth of the new product (the 'speed of diffusion between users). The faster the difficulties is, therefore diffusion is the greater are the possinbilities that early movers will fain intial advantages. Furthermore, the faster the diffusion is the greater are the possibilities that early movers will build sustanable, volume-related entry and mobility barries.  相似文献

ABSTRACT

Grassroots technological innovation (GRTI) is perceived as a source of sustainable development while addressing local problems and needs of people belonging to the bottom of the economic pyramid. The fostering of sustainable development develops a need for scientific evaluation and subsequent diffusion of GRTI to ameliorate the livelihood of grassroots communities. It is, hence, the purpose of this research to assess the relative performance of different GRTIs with respect to economic, social, and environmental benefits. The empirical data for this study comprised of 32 GRTIs from the three different rural non-farm sectors in the Indian context. Analytical hierarchy process is used for deducing the relative assessment of the selected GRTI against the aforementioned performance criteria. The findings of this study offer imperative insights into the field of technology diffusion and development at the grassroots level and suggest recommendations for sustainable policy formulation.  相似文献

Starting from a conceptualization of structural change as an uneven phenomenon punctuated by technological revolutions that give rise to long-term movements of real and monetary variables, i.e. long waves, this paper puts forth an explanation of radical technical change. Then, drawing upon Post-Keynesian theory, the neo-Schumpeterian school of techno-economic paradigms, and the work of Luigi L. Pasinetti, we suggest guidelines for economic policy to manage structural change and its consequences. While economic policy cannot by itself fully tame the dynamics of structural change, it can ameliorate its disruptive effects, firstly by helping us to manage the stagnation phase of the long wave in order to avoid a deep depression; secondly by preparing the way for a new long-wave and, thirdly, by facilitating the establishment of the institutional conditions for the diffusion of the new technological paradigm. The paper concludes by comparing these suggested policies with those pursued by the dominant western economies after the Second World War. We find that three broad factors—a misdiagnosis of the nature of the crisis that began in the 1970s; a shift in power relations that was strongly unfavorable to the working class; and the rise of neoliberal ideology—led to the adoption of policies that had disastrous social and economic consequences.  相似文献
