<正>技术创新扩散是技术创新通过一定的渠道在潜在使用者之间传播采用的过程。由于技术创新对生产率的影响,是依赖于它在潜在采用企业中扩散的速度与范围。因此,技术创新扩散理论是技术创新理论的重要组成部分。在《技术创新扩散方程》中对技术创新扩散速度进行了讨论,本文将对基本S型扩散曲线N(t)关于拐点的对称性进行讨论,给出了理论证明,同时对费雪尔——普莱模型及特性给出有关证明。  相似文献

在对产业转移与区域技术创新扩散的复杂网络结构进行分析的基础上,结合复杂网络和采纳阈值模型等相关理论,以技术类型为调节变量,构建了基于产业转移的区域技术创新扩散仿真模型,并借助Netlogo仿真平台进行了仿真分析。结果表明,产业转移规模、创新程度及信息整合与技术创新扩散速度均呈正向相关关系,但在技术创新扩散深度上,受阈值机制的影响,二者关系呈现阶段性变化规律,且在不同的技术类型情况下,转移产业规模、创新程度及信息整合对技术创新扩散深度的影响也存在差异性特征。最后为产业转移和区域经济管理者提出了相关对策建议。  相似文献

Abstract

The purpose of this paper is to introduce explicitly pleasure and belief in what aims at being a Humean theory of decision, like the one developed in Diaye and Lapidus (2005a). Although we support the idea that Hume was in some way a hedonist – evidently different from Bentham's or Jevons' way – we lay emphasis less on continuity than on the specific kind of hedonism encountered in Hume's writings (chiefly the Treatise, the second Enquiry, the Dissertation, or some of his Essays). Such hedonism clearly contrasts to its standard modern inheritance, expressed by the relation between preferences and utility.

The reason for such a difference with the usual approach lies in the mental process that Hume puts to the fore in order to explain the way pleasure determines desires and volition. Whereas pleasure is primarily, in Hume's words, an impression of sensation, it takes place in the birth of passions as reflecting an idea of pleasure, whose “force and vivacity” is precisely a “belief”, transferred to the direct passions of desire or volition that come immediately before action. As a result, from a Humean point of view, “belief” deals with decision under risk or uncertainty, as well as with intertemporal decision and indiscrimination problems.

The latter are explored within a formal framework, and it is shown that the relation of pleasure is transformed by belief into a non-empty class of relations of desire, among which at least one is a preorder.  相似文献

John Stuart Mill has traditionally been portrayed as self-contradictory and failing to construct a unified social theory. Recent scholarship, however, has challenged this view, finding Mill's work to be creatively synthetic in bridging the antinomies inherent in liberal democratic thought. This revisionist interpretation of Mill is advanced by an understanding of his theory of justice and its role in shaping his policy positions on issues such as welfare, education, voting rights, property rights, taxation, government intervention, and the future of capitalism.  相似文献

Neoliberal political movements advocate privatization of public pension systems. Globalization imposes pressure on nations to conform to neoliberal policy views with respect to the design and structure of social insurance, including public pension systems. The paper begins with an investigation of the economic, ethical and ideological dimensions of the privatization debates in the U.S.; it argues that privatization advocates may be largely moved by ideology, since the other reasons advanced appear weak or unfounded. The second part discusses the history of Social Security, the purposes for its creation, and some of its economic effects. Differences between public and private pension systems are considered. A brief international comparison of some aspects of public pension system finance and benefit structures is presented. The final section considers the ethical, macroeconomic and distributional implications of privatization, prefunding and payroll tax funding, and argues for a pay as you go system financed with income taxes. In order to promote equity, economic security, community, and social cohesion, public pension systems should be universal in coverage. In order to reduce the inequality, income insecurity, and aged poverty generated by market economies, public pension systems ought to be progressive: benefit/contribution ratios should be inversely proportional to income, and progressive income taxes should finance the system. To promote economic growth, the systems should be financed on a pay-as-you-go basis, and should not be prefunded except for an emergency reserve. The fiscal policy recommendations partially depend upon the theory developed by Abba Lerner in the 1940s, and recently advanced by Wynne Godley and Randy Wray: Lerner's “principle of functional finance.”  相似文献

Neurally reconstructing expected utility   总被引:2,自引:0,他引:2  
While the concept of “expected utility” informs many theories of decision making, little is known about whether and how the human brain might compute this quantity. This article reviews a series of functional magnetic resonance imaging (FMRI) experiments designed to localize brain regions that respond in anticipation of increasing amounts of monetary incentives. These studies collectively suggest that anticipation of increasing monetary gains activates a subcortical region of the ventral striatum in a magnitude-proportional manner. This ventral striatal activation is not evident during anticipation of losses. Actual gain outcomes instead activate a region of the mesial prefrontal cortex. During anticipation of gain, ventral striatal activation is accompanied by feelings characterized by increasing arousal and positive valence. These findings affirm the role of emotion in the anticipation of incentives, and may provide an initial step towards a neural reconstruction of expected utility.  相似文献

Maintenance consumption is an expense recovered in product prices, yet also a source of taste satisfaction which must be exhausted, rather than reinvested, from the capital affording it. This riddle is solved in the duplication rules: the cost of maintenance consumption is recovered in pay and prices, but an equal flow is exhausted from the human capital of the worker earning the pay. The rules impact tradition in several ways. If output is defined in principle as value added, then it cannot also be described as consumption plus net investment without double-counting the maintenance consumption recovered in prices. Also rate of return in the stationary state is not zero, but is the rate sufficient to offset the exhaustion of individual human capital. The rules lead to new insights into economic return, and support an argument that all growth at the scale of closure is due to productivity gain rather than to thrift.  相似文献
