The increasing importance of technology in the application world has imposed high demand on the research community for insightful and useful principles about “management of technological innovation” (MTI). This paper examines the academic legacy in terms of conceptual categories, causal relationships and taxonomy of relevant systems, and asserts from a system perspective that MTI as an applied science is still in its infancy.Based on methodological argument, this paper warns of the danger of hasty compromise of strategically important topics to “popular” definition of “researchability,” and suggests several research guidelines and approaches for this young interdisciplinary discipline:
1. (1)To explore new frontiers, use “proximate variables,” consider contextual factors and causation in broad terms, conceptualize “independently,” and pay more attention to case study method.
2. (2)To understand driving forces, be aware of practice, and focus on internal dynamics.
3. (3)To transcend complexity, adopt a hierarchical structure perspective and state-and-flow concept, and condense findings into configurations.
Finally, this paper urges the formation of an overall research strategy to accelerate the accumulation of MTI grounded knowledge.  相似文献

A learning-based model of repeated games with incomplete information   总被引:3,自引:0,他引:3  
This paper tests a learning-based model of strategic teaching in repeated games with incomplete information. The repeated game has a long-run player whose type is unknown to a group of short-run players. The proposed model assumes a fraction of ‘short-run’ players follow a one-parameter learning model (self-tuning EWA). In addition, some ‘long-run’ players are myopic while others are sophisticated and rationally anticipate how short-run players adjust their actions over time and “teach” the short-run players to maximize their long-run payoffs. All players optimize noisily. The proposed model nests an agent-based quantal-response equilibrium (AQRE) and the standard equilibrium models as special cases. Using data from 28 experimental sessions of trust and entry repeated games, including 8 previously unpublished sessions, the model fits substantially better than chance and much better than standard equilibrium models. Estimates show that most of the long-run players are sophisticated, and short-run players become more sophisticated with experience.  相似文献

Marginal areas of the world, including tropical highlands, tropical coastal zones, and arid lands, are problematical for development. They are ecologically special areas, often of vital consequence to the stability of more populated regions nearby. Commonly, their peoples are culturally distinct. To develop marginal areas it is suggested that “transformational” development may be appropriate. Transformational development recognizes the importance of equity and of working with existing resource systems already ecologically and culturally appropriate to the area. In marginal areas, a special application of transformational development could include incremental changes in existing systems and their connection to modern international systems so as to benefit the inhabitants of marginal areas and to supply commodities and goods demanded in the rest of the world. By rethinking ideas about resources, an exploratory framework for such transformation is examined. This framework uses the concept of “resource system”, a concept which might play an important part in the application of equitable future global development efforts.  相似文献

Symmetric (3,2) simple games serve as models for anonymous voting systems in which each voter may vote “yes,” abstain, or vote “no,” the outcome is “yes” or “no,” and all voters play interchangeable roles. The extension to symmetric (j,2) simple games, in which each voter chooses from among j ordered levels of approval, also models some natural decision rules, such as pass–fail grading systems. Each such game is determined by the set of (anonymous) minimal winning profiles. This makes it possible to count the possible systems, and the counts suggest some interesting patterns. In the (3,2) case, the approach yields a version of May's Theorem, classifying all possible anonymous voting rules with abstention in terms of quota functions. In contrast to the situation for ordinary simple games these results reveal that the class of simple games with 3 or more levels of approval remains large and varied, even after the imposition of symmetry.  相似文献

Presupposing Churchman's and Ackoff's definitions of a system, the notion of a holistic experiment is defined. A holistic experiment is an experiment on a nonseparable system for the purpose of determining the properties (measures of effectiveness) of the systems components. The basic problem of a holistic methodology is that of conceptualization: (1) the conceptualization of the systems “components,” (2) the conceptualization of the “teleological” standard that defines the systems components; and (3) the assessment of the degree of systems “separability.” Various guidelines for conceptualization are offered. These guidelines derive from such disparate disciplines of knowledge as the sociology of knowledge, the psychology of science, the philosophy of science, law, epistemology, ethics, and systems science. It is argued that the problem of defining an adequate methodology for holistic systems constitutes an “ill-structured” problem. The methodology for dealing with ill-structured problems is not the same as the methodology for dealing with well-structured problems. To date, the methodology of the management sciences has been overwhelmingly preoccupied with well-structured problems. Large-scale social experiments require a fundamentally different approach.  相似文献

A number of radically distinct models (inquiry systems) are described. The models derive from C, West Churchman's recent characterization of the history of Western epistemology. It is argued that only a few of these models are appropriate for technological forecasting problems. Most technological forecasting methodologies rest on a dubious philosophical foundation. They unreflectively assume that the inquiry systems which are appropriate for “well-structured” problems are also appropriate for “ill structured” problems. It is argued that technological forecasting is an inherently ill-structured problem and therefore requires a methodology which is uniquely suited to such problems. The Dialectical and Singerian Inquiring Systems are proposed as particularly appropriate for ill-structured problems.  相似文献

This article describes the mathematics underlying the Loglet Lab software package for loglet analysis. “Loglet analysis” refers to the decomposition of growth and diffusion into S-shaped logistic components, roughly analogous to wavelet analysis, popular for signal processing and compression. The term “loglet” joins “logistic” and “wavelet.” Loglet analysis comprises two models: the first is the component logistic model, in which autonomous systems exhibit logistic growth. The second is the logistic substitution model, which models the effects of competitions within a market. An appendix describes the current status of the software.  相似文献

We appreciate that the Italian central bank has been able to provide the requested information for our comparison of the research output of European central banks. Based on this information, the ranking of the Italian central bank improves considerably. Still, many small central banks have a better research performance than the Banca d'Italia and, after recomputation, our previous conclusion that “small is beautiful” is not compromised.  相似文献

Structural modeling has been under study in recent years as a method for dealing with complex societal problems, and is growing in acceptance as a tool for understanding complex social phenomena. Structural models demonstrate the interactions of the separate elements of a system and their combined overall effect. Thus, the nature of the problem for which this method of analysis is appropriate is different from complex problems of the traditional disciplines which lend themselves to reductionist approaches. This is because complex policy problems of society cannot be “solved” with precise analysis. Kenneth Boulding suggests that there are two ways to cope with a complex policy problem, either to “slice” the problem into partial equilibrium sections or “squeeze” it by aggregating numerous variables into a single index or macho variable. Structural modeling is an approach which comes under the general strategy of squeezing the problem and is promising because of the ability to include a range of macro variables which provide insights about social change. The articles in this issue treat several interesting aspects of this approach. In this article we wish to recall for consideration a central purpose for developing such methods. We have taken a historical approach to indicate some of the roots of the concern for the effect of technological process on social change. Within this context, we discuss the nature of the contributions made by the articles in this issue and what promise the methods offer to addressing the historical concern.  相似文献

Windfall revenues from foreign aid or natural resource exports can weaken governments’ incentives to design or maintain efficient tax systems. Cross-country data for developing countries provide evidence for this hypothesis, using a World Bank indicator on “efficiency of revenue mobilization.” Aid’s negative effects on quality of tax systems are robust to correcting for potential reverse causality, to changes in the sample, and to alternative estimation methods. Revenues from natural resources are also associated with lower-quality tax systems, but results are somewhat sensitive to the choice of resource dependence indicators, and to a few extreme values in the data. Disaggregating by resource type, revenues from fuel exports are found to be more strongly associated than revenues from metals and ores exports with inefficient tax systems.  相似文献

Using data for 163 countries, state of the “life span revolution” over the period 1980–2000 is studied in terms of measures of cross-country inequality and through least-squares and quantile-regression estimation of simple convergence models. Four main points are noted. First, dynamics of the cross-country distribution of life expectancy during these 20 years seem markedly different from those for the preceding decades: instead of the sharp “convergence” noted until the 1980s, there is lack of convergence and an indication of “divergence”. Second, the divergence is particularly marked during the 1990s. Third, spread of HIV/AIDS has probably been a significant factor in generating divergence during the 1990s. Fourth, besides the sizable temporal heterogeneity, quantile-regression estimates of convergence models reveal a substantial heterogeneity across the top and the bottom quartiles within each period.  相似文献

The idea of a dual-market structure in the early stages of a product's life cycle has become one of the most widely accepted ideas among new product marketing practitioners in the past decade. Concepts such as “Early Market/Main Market” and “Visionaries/Pragmatists” have entered the lexicon of high-tech executives to express the notion that the market for new products is composed of early and main markets with a discontinuity in the diffusion process in between them. Moreover, these concepts have been at least partially tested and verified in the marketing academic literature in the past few years.We extend this branch of research by investigating the timing issues in dual-market cases. We define Change-of-Dominance Time (CD-Time) as the number of years it takes main market adopters to outnumber early market adopters. We empirically investigate this timing issue on a comprehensive data set of new product sales in the consumer electronics industry. We find that regarding explanatory determinants of CD-Time, external influence, such as advertising, to the early market is the most important explanatory variable.We examine the relationship between CD-Time and other early product life cycle phenomena: Takeoff, Saddle, and Rogers' size of adopter categories. We found relatively high correlations between these phenomena and CD-Time.The answer to the question “When does the majority become a majority?” is indeed “at 16%”! In a dual-market setting, the average time at which the main market outnumbers the early market is when 16% of the market has already adopted the product. In terms of time, in 75% of the cases the majority becomes a majority in 5 to 10 years.  相似文献

There are two aspects in today's information revolution that started in the late 1970s. The first is an aspect referred to as “the third industrial revolution,” which triggers the transition to the “21st century system of Industrialization.” The information revolution in this sense brings the creation of new “breakthrough industries (new multimedia industries).” And the second aspect of the information revolution possesses the characteristics of both a technological revolution and a social revolution and brings about the arrival of the third phase of the historical evolutionary process of the modern civilization, which proceeds through three phases, namely “militarization, industrialization, and then informatization.”If the bearers of modern industrialization are a “group of enterprises” that have been engaged in the race in order to gain “wealth” (generalized means of exchange/exploitation power), and if these enterprises' activities have been exercised in the world market where their products have been sold, then it is appropriate to call the bearers of informatization a “group of intelprises.” They will be engaged in the race to gain “wisdom” (generalized means of persuasion/induction power), then stages of their activities can be called a “global intelplace” where “sharables,” that is, information and knowledge, will be disseminated. And now, toward the 21st century, the third phase of modernization, which can be called the “informatization/intelprise formation” or the “wisdom game” (intellectualism), is about to begin.Japan's “ie society (a society based on the ie principle—literally, it means “house” but here it is interpreted as cultural principle for organizing a society), which has been going through the process of evolution on the Japan Archipelago, has developed a network-based organization with little stratification within its infrastructure. In this sense, Japanese society can be characterized as a “network-oriented society” in which intelprises and an intelplace in the broad sense have functioned as the essential components of the society since Middle Ages. In general, an intelplace and intelprises that operate actively within this framework serve as the flexible bases for different types of social relations and institutions, such as states and markets and eventually integrate these into the society to a certain extent. In fact, it took place quite regularly during the modernization “in the narrow sense,” or Westernization of Japanese society after the Meiji Restoration. There exist some problems, however. Some of the characteristics found in Japanese society may become obstacles to activities aimed at the sharing and promotion of information and knowledge in the global intelplace and Japanese participation in the “wisdom game.” Badly needed are serious efforts for Japanese intelprise-formation to reduce these obstacles as much as possible.  相似文献

A civilization constitutes a durable social system of complementary traits. Some of the complementarities of any given civilization are between elements of “material” life and ones commonly treated as integral to “culture.” Identifying the mechanisms responsible for a civilization's observed trajectory involves, therefore, causal relationships that cross the often-postulated “cultural–material” divide. Complementarities make it difficult to transplant institutions across civilizations on a piecemeal basis. They imply that reforms designed to jump-start an economy will fail unless they are comprehensive. Civilizational analysis can benefit, therefore, from attention to institutional complementarities, including ones involving both cultural and material variables.  相似文献

We report here spatially explicit scenario interpretations for population and economic activity (GDP) for the time period 1990 to 2100 based on three scenarios (A2, B1, and B2) from the IPCC Special Report on Emissions Scenarios (SRES). At the highest degree of spatial detail, the scenario indicators are calculated at a 0.5 by 0.5 degree resolution. All three scenarios follow the qualitative scenario characteristics, as outlined in the original SRES scenarios. Two scenarios (B1 and B2) also follow (with minor adjustments due to scenario improvements) the original SRES quantifications at the level of 4 and 11 world regions respectively. The quantification of the original SRES A2 scenario has been revised to reflect recent changing perceptions on the demographic outlook of world population growth. In this revised “high population growth” scenario, A2r world population reaches some 12 billion by 2100 (as opposed to some 15 billion in the original SRES A2 scenario) and is characterized by a “delayed fertility transition” that is also mirrored in a delayed (economic) development catch-up, resulting in an initially stagnating and subsequently only very slow reduction in income disparities. The spatially explicit scenario interpretation proceeds via two steps. Through a combination of decomposition and optimization methods, world regional scenario results are first disaggregated to the level of 185 countries. In a subsequent second step, national results are further disaggregated to a grid cell level, taking urbanization and regional (rural–urban) income disparities explicitly into account. A distinguishing feature of the spatially explicit scenario results reported here is that both methodologies, as well as numerical assumptions underlying the “downscaling” exercise, are scenario-dependent, leading to distinctly different spatial patterns of population and economic activities across the three scenarios examined.  相似文献

Learning to Learn, Pattern Recognition, and Nash Equilibrium   总被引:1,自引:0,他引:1  
The paper studies a large class of bounded-rationality, probabilistic learning models on strategic-form games. The main assumption is that players “recognize” cyclic patterns in the observed history of play. The main result is convergence with probability one to a fixed pattern of pure strategy Nash equilibria, in a large class of “simple games” in which the pure equilibria are nicely spread along the lattice of the game. We also prove that a necessary condition for convergence of behavior to a mixed strategy Nash equilibrium is that the players consider arbitrarily long histories when forming their predictions.Journal of Economic LiteratureClassification Numbers: C72, D83.  相似文献

This study analyzes the effect of employing hired labor in the Kibbutz. The main motivations are the premises contained in the newly emerging “The Change” or “The New Kibbutz” approach. Using the traditional LMF model with heterogeneous labor, we show that, although using hired labor will improve the economic situation of the Kibbutz in the short-run, in the long-run Kibbutz membership will consist of only those types of labor to which the “Self Labor” principle applies.  相似文献

The possibility of introducing time-succession into a type of scenario approach used in futures research is examined, starting from Duperrin and Godet's SMIC-74 method, which deals with sets of nondated binary events and requires as input data the individual probabilities of these events and their time-independent conditional probabilities, taken by pairs. Time succession is then considered successively at two levels: 1)as a means used just to make conditional probabilities more accessible to intuition, following a proposal of Mitchell and Tydeman, to which a simplification is suggested; and 2) as a characteristic to be kept in the time-succession dependent scenarios that are finally dealt with. In the second the investigated period is split into q time “scenes,” as suggested by Olaf Helmer, and a method is proposed using the same algorithm as is used in SMIC-74, but in which binary events, as basic elements, are replaced by “boxed-events.” A boxed-event consists in the couple formed by an event and a “box” that represents either one of the q time scenes or the nonoccurrence of the event. The procedure by which experts can be consulted about the individual and conditional probability data required is described in some detail.  相似文献
