区位决策视角下的集群生命周期分析

本文在对当前产业集群生命周期研究述评的基础上,将集群周期划分为成长、成熟、衰退、再发展四个阶段,并从企业区位决策的视角对集群生命周期的不同阶段进行分析。然后通过考察企业区位决策因子的动态变化和集群区核心产业的区外出口量增长率、主导产业的企业数量、修正后的空间基尼系数来对生命周期阶段进行划分,分析不同阶段下政府的决策行为。     

晚清民初上海文人的经济生活与身份转型——以王韬、包天笑为例

近代上海城市的发展，把一批传统士人卷了进来，中国文人由此开始走出延续千百年的仕途经济，走向近代城市的分工体系和独立职业空间。作为晚清上海初始城市化的亲历者，王韬在文化心理和经济生活两方面，经历了一场由“士人”转向城市职业者的艰难蜕变。而生活于清末民初上海的包天笑，则以明确的职业归属感，取代了传统士人的仕宦情结，中国文人至此初步完成了由传统政教依附者向近代独立文化人的转型。     

随机模糊神经网络模型预测铁水硅含量

该文在考虑了具有模糊化和非模糊化的模糊逻辑系统用于高炉铁水含硅量[Si]时各种噪声干扰的同时,把模糊数学理论和随机系统理论结合在一起,建立了一种新的高炉铁水含硅量[Si]的智能预报模型,该模型是由非单值模糊化、模糊规则库、模糊推理机、特殊非模糊化构成的随机模糊神经网络逻辑系统.通过结合莱钢1号高炉实时在线采集的生产数据,进行仿真研究,结果表明,该套模型能够很好地预测高炉铁水含硅量[Si].

物料流量会计的深化——利用MFCA与LCA的整合评估外部损害成本

物料流量成本会计(MFCA)是一种环境管理会计运用工具,也是企业高级管理人员和现场生产经理制定决定的一种工具.MFCA通过减少废弃物来实现提高生产能力的目标.MFCA衡量了材料的物量和存量信息,即在生产过程中的原材料、备品备件以物流和货币的单位表示出来,将MFCA与生命周期评价(LCA)整合,以此来评估外部损害成本.     

数学教学的生活化与非智力因素开发

数学,源于生活,寓于生活,用于生活,高于生活。数学教学的生活化,不仅是数学教学的大势所趋,也是数学教学改革的应有之义。数学教学的生活化,不仅有利于非智力因素的开发,也有利于发挥非智力因素的作用。     

英国出台四大战略性产业应对金融危机

英国经过15年的繁荣后,成为本次金融危机中受创最严重的国家之一。为应对危机,英国将更多的希望寄托在科技创新上。纵观2009年英国的科技发展,一个重要的特点就是充分利用英国所具有的科技优势,进行经济结构调整。相继规划和出台了生命科学、低碳战略、数字英国和先进制造等四大战略性产业,用以应对金融危机。     

Complementarity and the Measurement of Individual Risk Tradeoffs: Accounting for Quantity and Quality of Life Effects

This paper considers the factors responsible for differences with age in estimates of the wage compensation an individual requires to accept increased occupational fatality risk. We derive a relationship between the value of a statistical life (VSL) and the degree of complementarity between consumption and labor supplied when health status serves as a potential source of variation in this relationship. Our empirical analysis finds that variations in an individual’s health status or quality of life and anticipated longevity threats lead to significant differences in the estimated wage/risk tradeoffs. We describe how extensions to the specification of hedonic wage models, including measures for quality of life and anticipated longevity threats, help to explain the diversity in past studies examining how the estimated wage–risk tradeoff changes with age.      

Why the structure of capital and the useful lives of its components matter: A test based on a model of Austrian descent

This paper centers on the structure of capital and the useful lives of its components by considering an economy with two representative firms, one producing a necessity and another producing a luxury. This difference determines their reinvestment opportunities. Therefore, while the one applies replacement, the other adopts scrapping. However, as these capital policies lead to different service lives, the analysis confronts the issues raised by Miller (Review of Income and Wealth 29:284–296, 1982, Review of Income and Wealth 36:67–82, 1990) and deals with them by drawing on Haavelmo’s (A study in the theory of investment, Chicago: The University of Chicago Press, 1960) suggestions regarding the aggregation of capital. Among other findings, it turns out that the simulation results are highly robust, thus demonstrating that real-world implications may be even stronger than strictly suggested by the model.
