效率工资的决定机理及在薪酬管理中的作用

效率工资理论认为 ,支付比市场工资更高的工资 ,劳动总成本可能更小 ,企业能获得更多的利润。工作转换模型表明 ,在其他条件不变时 ,企业支付较高的工资可以降低工人的工作转换率。效率工资理论在理论上和现实的薪酬管理中都展示了极其强大的威力。     

长三角区域市场的地区分割——基于边界效应模型的分析

改革开放以来,我国地方市场分割问题一直比较突出,而建立全国统一开放的市场是我国经济转轨中最重要的目标之一。如何实现经济协调发展是我国当前急需解决的一个重大问题。基于此目的,本文构造了一个以边界效应模型为基础的分析框架,以长江三角洲八城市的行业部门为样本,进行实证检验。通过投入产出法计算得到行业之间的边界效应值。结果表明,在长江三角洲地区诸多的行业中市场分割与地方保护仍然比较严重。因此,长江三角洲并未实现真正的市场一体化。     

Structural Decomposition Analysis of Physical Flows in the Economy

Many environmental problems can be attributedto the extraction and emissions of physicalsubstances. Increasing our understanding of theeconomic and technological driving forcesbehind these physical flows can contribute tosolving the environmental problems related tothem. The input-output framework is a usefulsetting in which to integrate detailedinformation about economic structure andphysical flows. In this article a specificmethod in input-output analysis is reviewed,namely Structural Decomposition Analysis (SDA).It is based on comparative static analysis,which decomposes historical changes of a policyvariable into determinant effects. SDA has beenapplied, for example, to analyze the demand andtechnological driving forces of energy use,CO₂-emissions and various other pollutantsand resources. This article examines thetheoretical aspects of structuraldecomposition, in particular those concerningphysical flows and environmental issues.Furthermore, the article includes an extensivesurvey of empirical studies.     

循环经济认知误区的实证分析

随着传统经济增长模式危机的出现，世界各国纷纷提出并开始建立循环经济。循环经济作为一种崭新的社会经济发展模式，人们对其认识还存在种种误区，其中认为循环经济是一种最终实现“全新的封闭式的零排放的资源利用方式”、“可解决一切环境问题”的观点最为典型。那么，是否真的存在完美的全社会物质循环呢？实现这种循环的代价是什么？本文以物质循环为基本假设条件，应用扩张环境分析用投入产出模型对社会实现全循环的可能性进行了理论探讨．并以日本为例应用该模型对日本物质循环现状和在现有条件下实现全循环的可能性及其成本进行了实证分析，论证了在现有条件下实现全社会完美的物质循环的难点。     

同类产品的定价模型研究

针对完全市场经济条件下运行的库存-销售系统中同类产品定价问题,提出了多产品组合定价决策模型.考虑到多产品的需求价格弹性和交叉弹性的影响,假定在已知价格浮动比例的情况下为产品制定投放市场价,使得价格发生调整后产品在一段时期内取得的投资收益最大,从而建立了一般化的二次规划模型.最后给出两种产品组合定价决策的案例,用二次规划的有效集法计算获得最优定价结果,对于多产品组合定价问题具有理论和实际价值.     

Inflation model of a semicommand economy

A semicommand economy can be defined as a system where the pricing of goods is influenced by the market but where the prices of production factors are under control of the state. The model presents various pricing and economic policy measures to deal with inflation. It is constructed as a dynamic supply-side focused, input-output model which differentiates nominal and real movements. It examines the possible responses of prices and the volume of production to certain measures or programmes to counteract inflation. The cases described are based on the present day Yugoslav economy.     

我国非农产业对农村剩余劳动力就业的影响

随着我国经济增长,大量农村剩余劳动力已从传统的农业部门转移到非农部门。考察和研究非农产业对农村剩余劳动力就业的影响,对于制定相关产业政策、促进农村劳动力转移,具有重要意义。     

物流市场供需的动态弹性分析

运用系统动力学的思想,通过对物流市场特点的分析,借助于动态弹性分析手段建立了物流市场供需的动态弹性模型。根据模型的结果模拟出了物流市场的供需趋势图,并借助于一个实例进行了具体运用,较准确的预测出物流市场的供需趋势,为决策提供了很好的支持。     

高技术产业与经济增长关联性的实证分析

文章通过1995～2004年高技术产业的相关数据,建立了数学模型,运用实证分析的方法,求得我国和典型地区高技术产业各行业对GDP的产出弹性,得出不同地区均有各自优势行业的结论,同时还分析了高技术产业对我国三次产业的调整作用,为我国高技术产业发展规划提供决策参考。     

World Oil Depletion Models: Price effects compared with strategic or technological interventions

World oil depletion, including natural gas liquids, was modelled in the past by many authors. Recently, Guseo and Dalla Valle have introduced and Guidolin has applied a new approach following perturbed life-cycle diffusion models. Here we examine joint effects of economic and strategic or technological interventions using a Generalized Bass Model (GBM). Statistical analysis takes into account three different hierarchical levels: natural diffusion, long memory interventions and stochastic components. The main results confirm the statistical significance of historical 1970s shocks and highlight a strong long memory effect due to an increase in oil production after World War II. The estimated peak-date, 2007, and the 90% depletion time, 2019, are determined under an equilibrium intervention hypothesis.
