This paper contributes to the debate surrounding the question of whether biotechnology, particularly its applications in agricultural and food-related industries, should be regarded as revolutionary or evolutionary (with some reservations about the vaildity of teh question). The potential to create a revolutionary techno-economic paradigm shift does exist but it is currently systems. It is also important to consider the motivations underlying statements about the revolutionary/ evolutionary nature of biotechnology, as some such statements are intended to influence events rather than to reflect them. The impact of small firms on the direction and place of revolutionary change in these industries is likely to be marginal, unlike the situation in the early phases of teh electronics/IT revolution. At present the lack of integration of policy initiatives by national governments and the EC is a major factor discouraging the rapid implementation of change.  相似文献

Contrary to most writings in the field of evolutionary economics which have a strong microeconomic flavor, here amacroeconomic evolutionary model will be presented in order to deal with themacroeconomic employment effect of technical change where there is just one old and one new technology. Several authors who favour an evolutionary approach to the theory of technical change share an optimistic view with respect to the macroeconomic employment effect of technical change. In the paper we are dealing with the question of whether this optimistic view is a necessary result of an evolutionary approach to technical change or rather of some other characteristic of the models used. It is shown that the evolutionary approach to technical change is not inherently optimistic or pessimistic with respect to the employment effects. Rather it is the labour market behaviour that will decide, whether the employment effects of technical change are positive, negligible or even negative.  相似文献

Although the empirical pattern of industry shakeout has been documented for many manufacturing industries, we know little about the processes by which market structure evolves in non-manufacturing service industries. This paper establishes detailed empirical observations about the consolidation of a single non-manufacturing industry, the wholesale distribution of pharmaceuticals. These observations are used to explore differences between manufacturing and wholesaling in both the patterns and explanations for consolidation and analyze the explanatory power of theories that link consolidation to technological change. The analysis demonstrates that theories developed to explain consolidation in new manufacturing industries have varying degrees of applicability to the consolidation of drug wholesaling. The observed patterns of exit, innovation, and growth suggest important modifications to evolutionary theories of market structure.  相似文献

In recent years there has been a growing belief that materials constitute a generic technology of revolutionary significance, ranking alongside information techno- logy and biotechnology. Our main aim is to examine the plausibility of this claim. In so doing we indicate what is distinctive about changes i n materials science and technology, and report on recent forecasts of potential change. Our second aim is briefly to discuss corporate and public policy on materials innovation i n a number of advanced countries. We present some preliminary jindings from interviews conducted with prominent UK materials producers and users. We conclude that there have been some important incremental and radical innovations i n materials technology. But because the diffusion of innovative materials and processes into different industry sectors and products has been uneven, i n terns of their current and likely future impact on the economy as a whole these changes cannot yet be described as revolutionary. The future impact of materials technology will depend not just on the materials innovation strategies of companies and governments, but on their ability to overcome users' conservatism and to convince them of the design and quality improvements that are possible.  相似文献

Bioeconomics as economics from a Darwinian perspective   总被引:2,自引:2,他引:0  
Bioeconomics—the merging of views from biology and economics—on the one hand invites the 'export' of situational logic and sophisticated optimization developed in economics into biology. On the other hand, human economic activity and its evolution, not least over the past few centuries, may be considered an instance for fruitfully applying ideas from evolutionary biology and Darwinian theory. The latter perspective is taken in the present paper. Three different aspects are discussed in detail. First, the Darwinian revolution provides an example of a paradigm shift which contrasts most significantly with the 'subjectivist revolution' that took place at about the same time in economics. Since many of the features of the paradigmatic change that were introduced into the sciences by Darwinism may be desirable for economics as well, the question is explored whether the Darwinian revolution can be a model for introducing a new paradigm in economic theory. Second, the success of Darwinism and its view of evolution have induced economists who are interested in an evolutionary approach in economics to borrow, more or less extensively, concepts and tools from Darwinian theory. Particularly prominent are constructions based on analogies to the theory of natural selection. Because several objections to such analogy constructions can be raised, generalization rather than analogy is advocated here as a research strategy. This means to search for abstract features which all evolutionary theories have in common. Third, the question of what a Darwinian world view might mean for assessing long term economic evolution is discussed. Such a view, it is argued, can provide a point of departure for reinterpreting the hedonistic approach to economic change and development. On the basis of such an interpretation bioeconomics may not only go beyond the optimization-cum-equilibrium paradigm currently prevailing in economics. It may also mean adding substantial qualifications to the subjectivism the neoclassical economists, at the turn of the century, were proud to establish in the course of their scientific revolution.  相似文献

China and the global business revolution   总被引:6,自引:0,他引:6  
As China joins the World Trade Organisation, the author questionswhether China's large firms will be able to compete on the globallevel playing field. Over the past two decades, Chinese largeenterprises have undertaken extensive evolutionary change (comparableto that of other latecomer countries such as Korea, Taiwan andSingapore) but, at the same time, the world's leading firmshave undergone a revolutionary transformation. Based on analysisderived from case studies made in the course of the China BigBusiness Programme at the Judge Institute of Management Studies,Cambridge, the author concludes that China's large firms havenot caught up with the world's leading businesses.  相似文献

Accounting for economic evolution: Fitness and the population method   总被引:4,自引:1,他引:3  
The theme of this paper is the general population dynamics of evolutionary processes, and, in particular, a number of accounting concepts that are central to any understanding of evolutionary processes of the variation-cum-selection retention kind. A population perspective, for example, turns out to be crucial to the study of the competitive process in economic systems defined at the level of industries, sectors and markets. Business rivalry, underpinned by differential innovative activity, is the basis of the differential survival and growth of competing economic activities and the strategies deployed to create sustainable differences in competitive selection characteristics are at the core of the capitalist dynamic interpreted as an adaptive, evolutionary process. This kind of evolutionary argument is necessarily concerned with growth rate dynamics and the explanation of the diversity of growth rates across entities in a population. However, the following discussion does not provide any causal explanation of economic evolution in terms of the determinants of growth rate differences, rather it provides a bookkeeping scheme in which different causal theories may be set and compared. Growth dynamics and structural change are the two central features of variation/selection processes within populations and I explore them in terms of three themes: namely, Logistic Growth Accounting; Competition Accounting; and, the Price Theorem. The unifying theme that links all three is their relation to the population method in evolutionary theory.   相似文献

The differing paradigms of ecological and neoclassical environmental economics have been described in various articles and books and are also embedded in different professional associations. However, we cannot take for granted that the paradigm debates described in the literature are actually mirrored in exactly the same way in the perceptions and opinions of researchers looking at sustainability from an economic perspective. This paper presents empirical results from a German case study on how economists and others involved in sustainability research from different schools of thought think about the issues of sustainability and economics, how they group around these issues, how they feel about the current scientific divide, and what they expect to be future topics of sustainability research.We analyze the data using cluster analysis. Based on a literature survey, we generated forty sustainability economics-related statements and asked 196 sustainability researchers about their degree of agreement or disagreement with these statements. In evaluating our survey results, we discuss to what extent the clusters that we identified do—or do not—represent the two schools of thought of ecological and neoclassical environmental economics. We also propose some fields of research that can help to bridge the gaps amongst sustainability economics researchers while clearly marking others that are more suitable for a scientific ‘competition of ideas’. Key results of the study are: We identify two primary scientific clusters, one clearly confirming the existence of the ecological-economics school of thought, and the other largely capturing the neoclassical environmental view. Yet, there are some surprising exceptions: Both schools of thought share a conceptual definition of sustainability that is integrative in considering ecological, societal and economic dimensions (‘three pillar concept’) and is geared at preserving the development potentials of society. We also find a shared critique of ‘pure economic growth’ strategies in our sample. These shared opinions may provide bridging concepts between the schools of thought. Also both clusters agree with respect to a wide range of future fields of sustainability economics research. Yet, the research agenda of the ecological-economics cluster contains a large number of additional topics, primarily related to social, distributional and evolutionary aspects of sustainable development. Strong divides between the clusters that seem to be more suitable for a scientific competition of ideas are primarily related to the question of how to achieve sustainability, including appropriate environmental policies.  相似文献

Two kinds of difficulties retard progress in technological forecasting uncertainties inherent in the subject itself and imprecision in its concepts. The latter difficulty exists whenever words have to be used in a general or traditional sense due to the lack of an agreed-upon operational definition. One such word and concept is industry [1]. The object of this paper is to present an operational definition of “industry” for use in forecasting, R&D, or innovative contexts, and to show how predictive, rather than just analogue, statements can then be made about industry and industries.  相似文献

Is novelty always a good thing? Towards an evolutionary welfare economics   总被引:1,自引:1,他引:0  
Evolutionary economists are increasingly interested in developing policy implications. As a rule, contributions in this field implicitly assume that policy should focus on the encouragement of learning and innovation. We argue that, from an individualistic perspective, this position is not easy to justify. Novelty and evolutionary change have in fact a rather complex normative dimension. In order to cope with this, the evolutionary approach to policy-making needs to be complemented with an account of welfare the background assumptions of which are compatible with an evolutionary world-view. Standard welfare economics is unsuited to the job, since the orthodox way to conceptualize welfare as the satisfaction of given and rational preferences cannot be applied in a world in which preferences tend to be variable and incoherent. We argue that, in order to deal with the specific normative issues brought up in an evolving economy, welfare should be conceptualized in a procedural way: At the individual level, it should be understood as the capacity and motivation to engage in the ongoing learning of instrumentally effective preferences. Evolutionary-naturalistic insights into the way human agents bring about, value, and respond to novelty-induced change turn out to be a valuable input into this extended concept of welfare. Finally, some implications of this concept are explored.  相似文献

In this paper, structural change in the Finnish manufacturing industries is studied using the theory of the aggregation of production functions and longitudinal plant-level data for the period from 1980 to 2005. To characterise the nature of structural change in 12 industries, we examine the invariance of aggregate production functions over time. Aggregate production functions need not be estimated because, according to the theory of the aggregation of production functions, the invariance can be analysed by investigating the stability of capacity density functions, which describe the distribution of value added in these industries. Even though the shapes of aggregate production functions alter over time in most industries, there are differences in timing and in the degree of turbulence across industries. The analysis confirms that in some industries (e.g., the paper industry) the late 1980s marked the beginning of a period of relatively strong structural change. The food and communications equipment manufacturing industries are examples of industries for which the 1990s was a period of turbulence.  相似文献

Science park has been widely recognized for its importance to the development of high-tech industries. However, as the space availability is limited, selection of firms with better efficiency and/or growth potential in specific high-tech industries to get into the science parks has become a critical issue for the Taiwan government. Accordingly, this study applies Data Envelopment Analysis (DEA), a multiple inputs-multiple outputs evaluation method, to analyze the comparative performances of the six high-tech industries currently developed at Taiwan's Hsinchu Science Park. Malmquist indices of productivity change are also used to analyze the growth potentials of the six high-tech industries. In addition, individual output/input ratio analysis is done to examine the differences on individual productivity items between the efficient and inefficient industries. The results of these analyses provide some policy implications for Taiwan and other countries facing the similar problems.  相似文献

Developing countries wish to achieve in a few decades what the developed countries accomplished in many centuries under conditions of relatively lesser resource constraints. Therefore, the developing countries cannot emulate the evolutionary experiences of the developed countries; they need a revolutionary approach in their development strategies. One plausible option for this revolutionary orientation could be the utilization of a technology-based strategy for national development planning. This article proposes undertaking certain measurement activities with respect to the technological system of a country, which would enable national decision makers to use technology as a strategic variable for socioeconomic development. The article briefly describes the role of technology as the master key for sustainable development, discusses the current activities related to the measurement of technology, presents a few conceptual schemes, and a framework for the assessment of national technological capabilities and needs.  相似文献

Environmental issues are acknowledged as problems which transcend boundaries at organizational and societal levles. By adopting the notion of product stewardship, companies are required to manage their products from conception to resurrection, while recognizing many stakeholder interests. This demands a new style of management which emphasizes collaborative structures. In the case of teh development of greener, more environmentally sensitive technology, there is a role for new collaborative networks which affect technology in either incremental or revolutionary ways. These networks can exist within the organization (intra-organizational), between organizations in the supply chain (trans-organizational) and with organizations at the domain level (supra-organizational). This paper analyzes the management, development and effect of thse networks on the greening of technology. It sets out a conceptual framework for exploring the role of collaborations in the management and development of environmentally sensitive technology. It than links the types of collaboration to empirical evidence from a detailed case study of a major internationa UK manufacturing company. The paper concludes by highlighting the implications for management and research that stem from the findings.  相似文献

This paper extends the empirical analysis on Rodrik’s (1995a) domestic investment‐led export growth model for East Asia to nine East Asian countries for a longer time period, 1960 through 2004, and tests whether openness Granger‐caused investment or vice versa. Our results suggest that there can be no single conclusion about the role of investment in East Asia. Causality has also changed for some countries in different time periods. We question the exogeneity of the investment boom in East Asia, a key assumption made by Rodrik. Government’s incentives encouraged investment in export industries through different channels.  相似文献
