The paper endeavors to illustrate that though the existing literature emphasizes the dynamic role of Scitovskian pecuniary external economies to account for the growth of innovations, highlighting particular types of market interdependence, such interdependencies can just highlight quasi-rent-led static adjustments that do not ensure an endogenous growth of innovations; the possibility of the growth of innovations remains exogenous. In this context, the present paper highlights the importance of division of labor-led dynamic technological external economies that ensures the endogenous growth of innovations, underlining the need of reinterpretation of Allyn Young in a broader Kaldorian-Keynesian perspective. In this perspective, finance-led investment in more productive opportunities not only supports increases in market size but also begets further investment in (still) more productive opportunities. This understanding provides a more dynamic conceptualization of Keynesian pecuniary external economies that are driven by Youngian technological external economies.  相似文献

Firms in m a y industrial sectors are seeking to capitalize on the promise of new information technology to generate new consumer products which can gain substantial markets. Where these are improved versions of familiar products, the marketing task is relatively easy, but many of the new product opportunities involve radically new types of consumer good and/or service. Drawing on studies of efforts to establish such radical innovations, this paper examines the problems that are confornted in attempting to define what sort of product is actually being created and how it may fit into consume life-styles. Though there is considerable discussion of these topics in industrial circles, it appears that until late stages of product development, little serious analysis of social issues is undertaken— if at all. Furthemore, such discussio of the nature and use of products are more intended to mobilize the group of actors who are needed to support the innovation than to feed substantial information about possible user reqquirements into the design process. The design process is much more liable to invorporate ideas derived from analysis of technological trends and the use of products in professional applications, than information derived from social scienc or market research.  相似文献

Attention is focused upon the adoption (demand) rather than the creation (supply) of new technology, which improves from time to time. Based on the expected flow of technological progress over which the firm (demander) has no control, it must decide either to adopt the current best available technology or to postpone adoption. The distinguishing features of the model are that more than one technological innovation is anticipated and expectations about the likelihood of such innovations are revised as time passes since the last innovation. Our analysis shows that the firm will adopt the current best practice if its technological lag exceeds a certain threshold; moreover, as time passes without new technological advances it may become profitable to purchase a technology that has been available even though it was not profitable to do so in the past.  相似文献

A model of endogenous growth, based on Schumpeter's notion of trustified capitalism, is developed and applied to firm-level data for the period 1973–1991. The model relates the market value of a firm to its current profits and to its R&D expenditures. The relationship depends upon the expected rate of knowledge growth, the expected value of an innovation and the elasticity of the R&D production function. Over the sample period, investors expected knowledge to grow at an average rate of 5 percent, a measure which reflects both process innovations and new product discoveries. Elasticities of the R&D production functions are estimated for thirteen industry groups and interpreted as measures of technological opportunity. There is no evidence of secular decline in technological opportunity over the sample period, but there is some evidence of diminishing returns to R&D intensity. Variations in technological opportunity over time are not correlated across industries. In contrast, the expected rates of knowledge growth at the industry level are highly correlated with the aggregate expected rate.  相似文献

In studies of large scale systems innovations or technological transitions, niches have been given a prominent role as incubators for the seeds of future technological systems. It is often argued that immature technologies rely on niches for their development, before they are able to compete in mainstream markets. This paper combines insights from economic theory and from technology studies to formulate a framework for understanding the dynamics of technological change in niches, and applies this framework to the case of fuel cell Auxiliary Power Units (APUs). We conclude that the choice of technology for APUs will be of critical importance in determining the role this market could have in shaping future developments in hydrogen and fuel cells. However, a number of factors are not strictly dependent on the technology used in fuel cell APUs. These comprise factors influencing external economies of scale, network effects, the behaviour of users and expectations.  相似文献

Environmental policy affects the distribution of market shares if intermediate goods are differentiated in their pollution intensity. When innovations are environment-friendly, a tax on emissions skews demand towards new goods which are the most productive. In this case, the tax has to increase along a balanced growth path to keep the market shares of goods of different vintages constant. Comparing balanced growth paths, we find that tightening the policy stance spurs innovation, because it increases the market share of recent vintages, and promotes environment-friendly technological progress. As a result the cost of environmental policy in terms of slower growth is weaker.  相似文献

Models with induced technological change in the energy sector often predict a gradual expansion of renewable energies, and a substantial share of fossil fuels remaining in the energy mix through the end of our century. However, there are historical examples where new products or technologies expanded rapidly and achieved a high output in a relatively short period of time. This paper explores the possibility of a ‘technological breakthrough’ in the renewable energy sector, using a partial equilibrium model of energy generation with endogenous R&D. Our results indicate, that due to increasing returns-to-scale, a multiplicity of equilibria can arise. In the model, two stable states can coexist, one characterized by a lower and one by higher supply of renewable energy. The transition from the low-output to the high-output equilibrium is characterized by a discontinuous rise in R&D activity and capacity investments in the renewable energy sector. The transition can be triggered by a rise in world energy demand, by a drop in the supply of fossil fuels, or by policy intervention. Under market conditions, the transition occurs later than in the social optimum. Hence, we identify a market failure related to path-dependence and technological lock-in, that can justify a strong policy intervention initially. Paradoxically, well-intended energy-saving policies can actually lead to higher emissions, as they reduce the incentives to invest in renewable energies by having a cushioning effect on the energy price. Hence, these policies should be supplemented by other instruments that restore the incentives to invest in renewable energies. Finally, we discuss the influence of monopoly power in the market for innovations. We show that market power can alleviate the problem of technological lock-in, but creates a new market failure that reduces static efficiency.  相似文献

Competition, Imitation and Growth with Step-by-Step Innovation   总被引:28,自引:0,他引:28  
Is more intense product market competition and imitation good or bad for growth? This question is addressed in the context of an endogenous growth model with "step-by-step" innovations, in which technological laggards must first catch up with the leading-edge technology before battling for technological leadership in the future. In contrast to earlier Schumpeterian models in which innovations are always made by outsider firms who earn no rents if they fail to innovate and become monopolies if they do innovate, here we find: first, that the usual Schumpeterian effect of more intense product market competition (PMC) is almost always outweighed by the increased incentive for firms to innovate in order to escape competition, so that PMC has a positive effect on growth; second, that a little imitation is almost always growth-enhancing, as it promotes more frequent neck-and-neck competition, but too much imitation is unambiguously growth-reducing. The model thus points to complementary roles for competition (anti-trust) policy and patent policy.  相似文献

在网络效应市场,技术创新对企业竞争力有着重要的影响。然而由于网络效应的作用,需求曲线发生改变,使市场均衡表现出"赢者通吃"的特征。这意味着,如果一项新技术的用户规模达不到临界容量,正反馈效应的存在将会使该技术被市场所抛弃。静态博弈和动态博弈的分析结果都表明,用户为了避免网络规模减小带来的效用损失,对新技术的采用往往采取观望态度,这将导致新技术难以达到最小网络规模要求的临界容量,也就无法取代旧技术的统治地位。为了加快新技术的扩散速度并成功战胜旧技术,企业在进行技术创新时应采取有效的技术创新策略:一是要采取合适的技术兼容策略;二是要鼓励和授权其他厂商使用自己的技术标准;三是要吸引辅助配套厂商共同进行技术研发。  相似文献

Using a matched innovation survey and structural business statistics, we investigate the impact of the introduction of new service products and other types of technological innovations on firm growth measured as subsequent two-year employment growth. Results, based on median and robust regression methods for manufacturing firms, show that, on average, both the introduction of new goods and process innovations have a significant and positive impact on subsequent firm growth. In contrast, the introduction of new services does not, on average, have a significant impact on firm growth for both manufacturing and service firms. However, quantile regressions show that the introduction of new service products has a significant and positive impact on firm growth for high-growth service firms. Finally, in manufacturing, the introduction of product innovations has a positive impact on firm growth at both the lower and higher ends of distribution (i.e. for both high-growth and shrinking firms).  相似文献

Coopetition (collaboration between competing firms) is used in many contemporary industries to achieve various innovation-related benefits. However, there is still a lack of consensus in the existing literature as to whether it is beneficial in the case of radical innovations or whether it only supports incremental improvements due to the similarity of knowledge bases among competitors. We address this issue in an empirical study based on a cross-industrial survey in Finnish markets. The study focuses on three types of technological coopetition and on their effect on the technological, market and business-model radicalness of the firms’ innovations. The results show that coopetition is negatively related to technological radicalness and positively related to business-model radicalness. The implications are that coopetition is likely to benefit incremental technological development over time and to promote the emergence of radical business-model innovations as competitors seek to differentiate their offerings.  相似文献

Environmental regulations are often intended to stimulate the generation and adoption of eco-efficient innovations. An important argument in the public debate is also the creation of new markets for environmentally benign products, processes and services in other countries and the generation, as a result, of export opportunities for the pioneering country (lead markets). Research on lead markets has not, however, focused on environmental innovations to date. We therefore extend the lead market model to environmental innovations and take particular account of the peculiarities of such innovations, in particular, the public good character of environmental benefits and the role of regulations. This approach is applied to two case studies: wind energy and fuel-efficient passenger cars. In both cases, the innovation was initially adopted in one country. Other countries subsequently adopted the same innovation design favored by the lead market which, in turn, developed into a large exporter in the wind generation and car industries, respectively. We discuss the regulations employed and the reasons for the international success of the innovations induced by them. Our findings demonstrate that when supported by global demand or regulatory trends, strict regulation results in the creation of lead markets. Finally, we provide recommendations on how our model could be used for further research and in the development of a coordinated environmental and innovation policy.  相似文献

Graded eco-labels: A demand-oriented approach to reduce pollution   总被引:1,自引:0,他引:1  
Supplied oriented environmental policies are generally used in order to limit production related pollution. This fact is based on the hypothesis that consumers are not willing to sacrifice personal utility for a wider social gain. We suggest that widespread environmental concerns of consumers can be exploited to push producers along cleaner technological patterns. Our core assumption is that consumers would be ready to purchase cleaner products if the products' characteristics are not ‘too dissimilar’ to those of more polluting alternatives. However, due to a lack of information about non-observable product characteristics, this assumption on its own is not sufficient for ‘environmental friendly’ producers to become competitive. We show - by means of a simulation model - that only if consumers are provided with appropriate information on the greenness of products through adequate eco-labels (graded eco-labels), then producers will be pressed to implement innovations aimed at reducing the environmental impact of their products. Under two test settings - one without any certification and another with binary eco-labels - the model shows markets characterised by highly polluting technological patterns. Only in the presence of graded eco-labels, competition drives the market toward cleaner technological patterns.  相似文献

This paper is a contribution to the analysis of how rapid technology change influences market structure. The paper uses a simple simulation model to explore the effects of four main factors on the development of market structure. These are: (1) the variance (or unpredictability) of the technology trajectory; (2) the speed with which the organisation's ‘technological vision’ adjusts to ongoing technological developments; (3) the absorptive capacity of each division in the multi-divisional firm to experience gained in other divisions; (4) the extent to which competence-destroying innovations generate greater cost penalties for the division of a multi-divisional firm than for a comparable mono-divisional firm. Simultion results are obtained for 100 technological trajectories, and a variety of parameterisations. While there is a tendency for noisier trajectories to disadvantage the larger multi-divisional firm, there are conditions under which such a firm benefits from a noisy technological environment. When competence-destorying innovations affect the division of a multi-divisional firm no worse than the comparable mono-divisional firm, the multi-divisional firm is not disproportionately affected by a noisy trajectory. It may, however, be seriously damaged by a slow adjustment of technological vision, especially when all scale economies are dynamic (rather than static). The simulations confirm that the absorptive capacity of each division to experience from others can be critical in determining the ultimate market structure. A brief empirical motivation for the model is offered by reference to some case studies of the semiconductor industry.  相似文献

The importance of technical change, through the innovative activity of industry, has received a lot of attention in the regional economic literature. Regional policy has now begun to reflect the changing emphasis in the recent literature, and especially the key role of inventive activity in achieving long-run self-sustaining regional growth. This paper concentrates on research activities in terms of inventive inputs (R&D) and innovative outputs (especially patented innovations). In general the results suggest that there is a low level of technological activity in Northern Ireland, especially in industries that are characterized as being technologically advanced. This is partly because external ownership reduces R & D activity which in turn reduces innovation outputs but there is also a problem in that companies in Northern Ireland are relatively unsuccessful at producing new products and processes of the type and quality required in the market place. The availability of government-sponsored R & D grants since 1977 has begun to redress the imbalance in terms of R & D activities but there is, as yet, little information to show that the level of technological success has increased.  相似文献

It is argued that the firm is the principal source of innovation and growth, a device for the establishment of technological competence, and for its continued development over time. Markets, products and background knowledge may change quite dramatically over time. Yet as a result of the cumulative nature of learning in the production processes of firms, the profile of corporate technological competence will tend to persist over quite long periods, provided there is institutional continuity. Within the same firm, competence may evolve into related areas, but the firm's technological origins will remain identifiable in its subsequent trajectories. However, if the institution itself changes more dramatically, this technological persistence may be disrupted. Supporting evidence is provided from data on the patenting of 30 large US and European companies, which have been continuously active since the interwar period. The science and the knowledge base, and the composition of products and markets may shift quite radically, but the firm's productive and technological system itself is potentially more stable. The firm provides a vehicle for potential institutional continuity and a device for managing transitions within the economic system.  相似文献

A transition of the energy sector towards a renewable-based system is one of the challenges that results from the debate on the global climate problems and diminishing fossil fuels. This will demand access to innovations in energy production technologies and usage. However, policies directly focussing on innovation and diffusion of new technologies are losing ground. Policy discussions have been dominated by the liberalisation of energy markets and the introduction of new economic instruments all over Europe. Whether this delegation of responsibility for the transition to new economic instruments provides the expected innovations is questionable.In Europe, Denmark has served as an example country being one of the front runners in the development of energy technologies based on renewable sources, especially wind turbines. But also in Denmark policy preferences have changed from the support for technological innovation and implementation to support for delegating responsibility to a market for green energy and CO2 certificate trading.The different policy regimes marking this change are analysed concerning their ability to support technological innovation. Important elements for the construction and legitimacy of policy regimes comes from academic disciplines involved in policy design. The analysis highlights the basic arguments and the type of knowledge involved and indicates some of the limitations in the measures' ability to solve the problems delegated to them. Experience thus far provides little if any evidence that simple, market-based models can facilitate the need for future energy technology innovations in a satisfactory way, which leads to a need for more complex and heterogeneous sets of measures.  相似文献

This paper assesses the role of inventive and innovational activity in the growth process of Canada, a country which relies overwhelmingly, some 90 per cent, on the importation of technological advances and operational know-how from abroad. Canada has prospered under this arrangement but at a price. With technology came foreign capital, foreign management and substantial foreign control. To lessen Canada's dependence on foreign know-how, this country has embarked on an expanded R & D programme. But the pay-off from these efforts has been less than expected. To throw a light on the subject, the results of two new surveys are presented: one a sample survey of patents granted, the other an interview survey of large corporations. Questions examined include sources of know-how and technological advances, utilization of inventions and abandonment of innovations, R & D and innovations, domestic and foreign innovations, and the profitability of innovations. Aggregative assessment is supplemented by disaggregative analysis using cross-section and industry data.  相似文献
