We consider an urban foreign enclave with sector-specific foreign capital in an otherwise mobile-capital Harris-Todaro model. We consider the taxation of foreign capital. A dynamic version of this model is considered. The long-run equilibrium and the comparative steady-state effects are analyzed. We get some interesting effects of reduction in tax rate on foreign capital on the short-run and the long-run equilibrium levels of domestic factor income and national income under some meaningful conditions.  相似文献

Different kinds of networks, such as transportation, communication, computer, and supply networks, are susceptible to similar kinds of inefficiencies. These arise when congestion externalities make the cost for each user depend on the other users' choice of routes. If each user chooses the least expensive (e.g., the fastest) route from the users' common point of origin to the common destination, the result may be Pareto inefficient in that an alternative choice of routes would reduce the costs for all users. Braess's paradox represents an extreme kind of inefficiency, in which the equilibrium costs may be reduced by raising the cost curves. As this paper shows, this paradox occurs in an (undirected) two-terminal network if and only if it is not series-parallel. More generally, Pareto inefficient equilibria occur in a network if and only if one of three simple networks is embedded in it.  相似文献

Under technology convergence phenomenon and fast-changing social demands, it is inevitable to collect and analyze a large amount of information in order to determine a vacant technology area that can preempt the market. Thus, this research aims to propose a systematic approach to identifying vacant technology areas by reflecting the technological competitiveness of company. Vacant technology is identified as underdeveloped and undeveloped vacant areas for a firm in both macroscopic and microscopic view by generating a technology level map in a practical view. In addition, vacant technology can be identified as undiscovered vacant areas in a microscopic view by using generative topology mapping (GTM) and local outlier factor (LOF). In a respective view, the promising vacant areas are defined by developing various indicators that represent competitive strength, growth stage, and marketability in both macro and micro level, and novelty indicators that represent originality and marketability in the micro level. The proposed approach is applied to the information & communication technology (ICT) R&D technology classification to validate its usefulness. The results can be used to enhance the practical application of R&D technology planning, understand the current technology level, and perform future technology planning.  相似文献

Technology roadmapping offers a flexible instrument to portray development status in support of technology forecasting and assessment. This paper integrates bibliometrics with qualitative methodologies and visualisation techniques to construct a hybrid model for composing technology roadmaps. The mapping arrays details on the evolution of the technology under study and contributes to understanding the macro-technology development status. We generate a global technology roadmap for electric vehicles to demonstrate the approach in an empirical study.  相似文献

This article develops and uses a futures sensemaking and decision-making tool with which to navigate the multi-ontology topology of strategic landscapes. The research approach is design science; i.e., research clearly targeted at developing a means to an end. The tool is described according to an eight-point structure of a design theory proposed by Gregor and Jones (2007), presenting specific testable propositions. The authors show how the tool works in three practical cases by referencing an underlying kernel theory, sensemaking theory.  相似文献

股份重建与农村集体经济改革   总被引:1,自引:0,他引:1  
农村集体经济改革不能是“解散生产力”,而应是“解放生产力”,关键要建立起符合现代产权制度的新型治理结构,促进农村生产力的不断提高。无锡建立股份经济合作社是深化农村集体经济改革的一次重要尝试,它明晰了集体经济中农民的所有者权益,建立了集体经济发展的新机制,对促进农村社会经济全面协调可持续发展具有重大意义。  相似文献

斯拉法模型的分析与重建 --兼论三类价格理论的层次关系   总被引:2,自引:0,他引:2  
鲁品越 《财经研究》2005,31(4):69-79,144
供求决定论、斯拉法模型和劳动价值论是三类价格决定理论.用生产过程中的技术关系以及劳动与资本的利益关系来解释商品世界的价格体系,是斯拉法模型的卓越贡献.然而斯拉法封闭在该价格体系内部,通过建立"标准体系"的"标准合成商品",并将其还原为所购买的劳动量,以确定价格单位,构成了斯拉法理论的赘疣与困境.为了摆脱困境,必须寻求相对价格体系背后的价值实体,重建这一价格模型,使其融入到以劳动价值论为基础的价格决定机制的三个层次中.  相似文献

在重建的工作上。外来的人才、资金和技术亦将举足轻重,有望令灾区尽快恢复生产,经济尽快重回发展的轨道。但与此同时。外来助力却始终无法代替本地人自力更生的精神。以及渴望重建家园的驱动力量。如何促进产业结构适当调整,经济布局得到合理安排。及实现人与自然和谐相处,凡此种种,不但需要外来专家学者的论证,更有赖本地相关群体的认同和参与。  相似文献

流通经济学的贫困与构建设想   总被引:10,自引:0,他引:10  
在区分了流通经济学与流通理论的不同后,本文认为流通经济学存在着贫困现象。这种贫困的原因在于经济学在发展的过程中忽视了对流通问题的研究,比如新古典经济学生产者与消费者直接见面的假设使流通被抽象掉了;经济学格式化的过程又间接影响了经济学对流通问题的研究;经济学家认识能力的有限性又限制了经济学关注流通的视野。我国流通理论的建立基础注定我国流通经济学的研究先天不足。在分析了流通经济学贫困原因的基础上,本文针对流通经济学研究对象的界定、流通经济学建立的理论基础以及马克思流通理论的地位等问题对流通经济学的体系构建提出了一些初步设想。  相似文献

Automakers are facing a growing process of financialization that can be characterized by the preference to value capital through financial activities as more profitable than by productive activities. The aim of this article is to study the financialization of the automotive industry by analyzing the five largest automakers in the world: Toyota, Volkswagen, Hyundai, General Motors (GM) and Ford. The profitability of financial activities was compared to that of productive activities; shareholder structure; share acquisitions; origin of top managers; compensation to executives; employee salaries; dividend payments to shareholders and employment. The results showed that increasingly more financial activities are fundamental to businesses dominated by major shareholders. Dividend payments have shown compliance to shareholder value maximization principles. Compensation to executives has shown that there is a layer of highly paid top managers, while in the workforce, salaries are below the average of the countries in which the automakers operate. The proportion of times that a CEO’s earnings outweigh the average earnings of less skilled workers is hundreds of times. Employment has been changing, with significant increases in China, for instance. This article aims to improve the knowledge of this important sector of world industry and contribute to development of economic sociology.  相似文献

中国矿产资源税费体系重构   总被引:1,自引:0,他引:1  
高速增长和增速减缓的不同经济状态下暴露出的矿产资源税费制度缺陷,迫切需要构建新的矿产资源税费制度。依据福利经济学和国家权利理论,矿产资源优化配置要求在产权明晰的前提下矫正各种市场失灵。政府是矫正市场失灵的主体,政府通过行使矿产资源所有权和政治权收缴权利金及矿业权费,征收资源税和特别收益金,建立收益调节基金,将外部性内部化,矫正市场失灵。  相似文献

我国农业生态系统营养循环链的断裂与重建   总被引:9,自引:0,他引:9  
完整的营养循环是农业生态系统健康、可持续发展的重要保障。我国传统农业属于环境友好型生态农业。农业生态系统的营养循环结构完整,持续健康、繁荣。但是,随着工业化、城市化、市场经济的发展以及农业耕作方式的转变,农业生态系统营养循环的结构遭到严重破坏,导致一系列资源、环境、经济与社会问题。通过秸秆还田以及城市生活废弃物(排泄物、厨房垃圾等)向农业生态系统的返还,重建农业生态系统完整的营养循环,是我国农业生态系统持续健康发展的必由之路。  相似文献
