Innovative profits (of the kind conceptualized by Schumpeter) are today being increasingly created through international corporate networks for technological development. Such profits through innovation are encouraged by newer more flexible organizational forms, and further encouraged (unlike in the conventional perspective on profits and on the incentive to innovate) by knowledge flows between firms. Our empirical evidence, based on US patent data, shows that multinational companies are currently more likely to develop abroad technologies which are less science-based, and less dependent upon tacit knowledge. However, within the science-based industries firms may generate abroad some technologies which are heavily dependent on tacit knowledge, but normally in fields that lie outside their own core technological competencies. We find some evidence of a convergence in corporate technological diversification across large firms, facilitated by the now common spread in the use of information and communication technologies (ICT) as an integrator of formerly separate technological systems. This has led smaller firms to diversify, but giant firms to consolidate activity around those technologies that have become most interrelated.  相似文献

Abstract. Economic theories of managing renewable resources, such as fisheries and forestry, traditionally assume that individual harvesters are perfectly rational and thus able to compute the harvesting strategy that maximizes their discounted profits. The current paper presents an alternative approach based on bounded rationality and evolutionary mechanisms. It is assumed that individual harvesters face a choice between two harvesting strategies. The evolution of the distribution of strategies in the population is modeled through a replicator dynamics equation. The latter captures the idea that strategies yielding above average profits are demanded more than strategies yielding below average profits, so that the first type ends up accounting for a larger part in the population. From a mathematical perspective, the combination of resource and evolutionary processes leads to complex dynamics. The paper presents the existence and stability conditions for each steady-state of the system and analyzes dynamic paths to the equilibrium. In addition, effects of changes in prices are analyzed. A main result of the paper is that under certain conditions both strategies can survive in the long-run. Correspondence to: J. Noailly  相似文献

在新旧技术竞争过程中,传统企业会适时调整研发策略,以应对新技术进步对传统技术造成的冲击。然而,新技术对传统技术的影响究竟表现为创新替代效应还是创新互补效应,至今依然没有得到确切结论。以汽车产业为研究对象,比较传统燃油汽车和电动汽车两种新旧技术的发展路径,并结合产业生命周期理论提出汽车产业的三阶段演化模型。进一步基于1995—2021年省级专利数据和面板向量自回归模型,从产品创新和工艺创新两个维度实证检验各阶段电动汽车技术进步对传统汽车企业创新的影响。结果表明,在电动汽车产业的范式导入期(1995—2008年),新技术通过产品创新和工艺创新两方面促进传统技术发展;在电动汽车产业的范式构建期(2009—2021年),新技术依然对传统技术有显著推动作用,但仅通过工艺创新促进传统技术发展。  相似文献

Evolutionary economics and economic geography   总被引:19,自引:0,他引:19  
This article attempts to explore how key notions from Evolutionary Economics, such as selection, path-dependency, chance and increasing returns, may be applied to two key topics in Economic Geography. The first issue is the problem of how to specify the (potential) impact of the spatial environment on new variety in terms of technological change. Evolutionary thinking may be useful to describe and explain: (1) the process of localized `collective' learning in a regional context, (2) the adjustment problems that regions may be confronted with in a world of increasing variation, and (3) the spatial formation of newly emerging industries as an evolutionary process, in which the spatial connotation of increasing returns (that is, agglomeration economies) may result in a spatial lock-in. The second issue is the problem of how new variety may affect the long-term evolution of the spatial system. We distinguish three approaches that, each in a different way, apply evolutionary notions to the nature of spatial evolution. This is strongly related to the issue whether mechanisms of chance and increasing returns, rather than selection and path-dependency, lay at the root of the spatial evolution of new technology.  相似文献

Growth and equilibrium indeterminacy: the role of capital mobility   总被引:3,自引:0,他引:3  
Summary. The paper presents a human capital driven endogenous growth model which, in general, permits a multiplicity of equilibrium balanced growth paths. It is shown that allowing for perfect capital mobility across countries increases the range of parameter values for which the model permits equilibrium indeterminacy. As opposed to the closed capital markets case, simple restrictions on preferences are no longer sufficient to eliminate the indeterminacy. Intuitively, under perfect capital mobility agents are able to smooth consumption completely. This induces an economy with open capital markets to behave like a closed economy with linear preferences thereby increasing the possibility of equilibrium indeterminacy.

This paper attempts to empirically test the hypothesis that whether debt matters in the EU. This has been performed by examining the potential adverse effects of debt in large European economies on investment, inflation and growth. Using the hybrid cointegration and vector autoregressive models, the findings, based on the period 1970–97, suggest that debt causes significant adverse effects on investment, but its impact on growth is not clear-cut. Moreover, debt appears to be inflationary in most cases in the long run, though produces no clear short run pattern on inflation.  相似文献

Several researchers looking at the development of international export specialisation patterns have shown that there is a weak tendency for OECD countries to exhibit decreased levels of specialisation. This finding is in contrast to findings made by other authors, who found increasing technological specialisation. The first aim of this paper is to investigate whether these contradictory findings are due to a `real world' phenomenon, or whether the explanation is purely technical, by comparing the development of export specialisation to specialisation in terms of US patents, using the same methodology and level of aggregation. The second aim is to analyse the extent to which countries and sectors display stable specialisation patterns over time, also both in terms of exports and in terms of technology. The paper confirms that the OECD countries tend in general to become less specialised in terms of exports. The evidence is less conclusive with regard to technological specialisation, as the results are mixed in the sense that just about half of the countries tend to exhibit increased levels of specialisation, while the other half tend to exhibit lower levels of specialisation. In terms of country and sectoral stability of specialisation patterns, it can be concluded that both trade specialisation and technological specialisation patterns are path-dependent. In comparison, however, trade specialisation patterns are more stable than are technological specialisation patterns.  相似文献

Technology trend analysis anticipates the direction and rate of technology changes, and thus supports strategic decision-making for innovation. As technological convergence and diversification are regarded as emerging trends, it is important to compare the growth patterns of various technologies in a particular industry to help understand the industry characteristics and analyse the technology innovation process. However, despite the potential value of this approach, conventional approaches have focused on individual technologies and paid little attention to synthesising and comparing multiple technologies. We therefore propose a new approach for clustering technologies based on their growth patterns. After technologies with similar patterns are identified, the underlying factors that lead to the patterns can be analysed. For that purpose, we analysed patent data using a Hidden Markov model, followed by clustering analysis, and tested the validity of the proposed approach by applying it to the ICT industry. Our approach provides insights into the basic nature of technologies in an industry, and facilitates the analysis and forecasting of their evolution.  相似文献

Uncertainty and the size distribution of rewards from innovation   总被引:4,自引:1,他引:3  
 Previous research has shown that the distribution of profit outcomes from technological innovations is highly skew. This paper builds upon those detailed findings to ask: what stochastic processes can plausibly be inferred to have generated the observed distributions? After reviewing the evidence, this paper reports on several stochastic model simulations, including a pure Gibrat random walk with monthly changes approximating those observed for high-technology startup company stocks and a more richly specified model blending internal and external market uncertainties. The most highly specified simulations suggest that the set of profit potentials tapped by innovators is itself skew-distributed and that the number of entrants into innovation races is more likely to be independent of market size than stochastically dependent upon it.  相似文献

The central theme of this address is the complicated relationship between the growth of the economy and the growth of knowledge. This theme is explored with the help of a single concept “restless capitalism” which is used to capture the idea that capitalism in equilibrium is a contradiction in terms precisely because the growth of knowledge cannot be meaningfully formulated as the outcome of a constellation of equilibrating forces. This theme is explored through a discussion of growth accounting, the relationship between innovation, markets and institutions and, as an example, the development of innovation in the field of ophthalmology. We also discuss some pioneering contributions made by Simon Kuznets and Arthur Burns to the discussion of evolutionary growth. From this Schumpeterian perspective we see the economy as an ensemble not an aggregate entity and so see more clearly the importance of microdiversity in the relationship between growth of knowledge and growth of the economy.  相似文献

One way of thinking about research and development is to recognise that firms are trying to solve particular design problems. We often build these design problems into our models, but are forced to oversimplify them in order to make the models solvable. The approach taken in this paper is to acknowledge that design problems are often insoluble using standard techniques and to model instead the process by which firms solve them. Two such processes are simulated in detail. The first, individual experimental search, is based on a problem-solving technique known as simulated annealing. The second, partial imitation, involves learning at a social level and is based on a problem-solving technique known as the genetic algorithm. Some economic implications of these processes are explored, including their application to stochastic learning curves, patent design and the importance of `technodiversity' in the introduction of new technology to developing countries.  相似文献

Starting from a discussion of Schumpeter's analysis of the relationships of capitalism, socialism and democracy, it is shown that, in a complex society, democracy is only compatible with a decentralized market economy with safe property rights. But in time democracy shows a tendency to weaken the capitalist system by more and more regulations and an ever-increasing share of government (including the social security system) in GDP. This tendency is a consequence of political competition because of the development of interest groups and the presence of rationally uninformed voters. It leads to a weakening of efficiency, investment, innovation and thus to lower growth rates of GDP. But in time forces opposing this development arise. First, because of the negative consequences of growing government the welfare and regulatory state is bound to move into a crisis in the long run. Thus innovative politicians have a chance to win the support of a majority of voters for reform projects, who perceive finally the ever-increasing burden of higher taxes and regulations and realize that these burdens are not worth the benefits bestowed on them. In doing so, they may face, however, the competition of ideologies. Second, there are other states with lower taxes and less unnecessary regulations which show higher growth rates of GDP, and gain thus relative advantages in international political and military competition since they can command greater resources with the passage of time. To maintain their relative international power position, reforms are thus considered as necessary by rulers. This may be helped by pressure resulting from comparisons of the standards of living done by their citizens.  相似文献

Satiation in an evolutionary model of structural economic dynamics   总被引:1,自引:0,他引:1  
This paper presents the problem of satiation of consumption and technology in relation to a model of evolutionary endogenous growth. The model represents an attempt to provide an evolutionary economic micro foundation to Pasinetti's scheme of the structural economic dynamics of an economy that is based on only labour and knowledge. The micro foundation is based on a set of rules that makes endogenous the demand coefficients, the labour coefficients, and the number of available sectors. Through process innovations firms increase their productivities with respect to individual goods, but a growth slowdown takes place unless the benefits from specialisation are exploited at still higher levels. Another cause for slowdown is related to an Engelian hierarchy of goods. As the standard of living grows, existing sectors and consumption goods satiate, so new sectors need to be provided by product innovations in a sufficient pace to keep up with the labour that is displaced from old sectors.  相似文献

This paper here proposes a theory of classification and evolution of technology based on taxonomic characteristic of interaction between technologies that is an under-studied field of research in economics of technical change and management of technology. The proposed classification of technologies, in a broad analogy with evolutionary ecology of parasites, within a theoretical framework of Generalised Darwinism, is: (1) parasitic technologies, (2) commensal technologies, (3) mutualistic technologies, (4) symbiotic technologies. This theory here suggests the property of mutual benefaction from interaction between different technologies and the theorem of not independence of any technology to explain and predict characteristics and evolutionary pathways of technologies over time. Overall, then, this study may be useful for bringing a new perspective in economics of innovation to categorise and analyse the interaction between technologies that can be a ground work for development of more sophisticated concepts to explain and predict the evolution of technology and generalise aspects of technological change in human society.  相似文献
