用户需求的发展趋势对产品设计的启示

“以人为本”的设计理念包含绿色设计、人性化设计、个性化设计三大设计趋势,必须与合理的产品结构及功能相协调,一个好的设计应当在用户需求和理性设计中找到平衡点。     

《人力资源管理综合应用软件》课程教学的探讨

《人力资源管理应用软件》是一门实践操作性很强的课程,本课程充分利用我院人力资源管理专业模拟实战室的优势,按照我专业学生培养目标的要求,加强人力资源管理专业学生的四项核心技术的训练.本文就《人力资源管理应用软件》课程的教学方法提出的自己的看法.     

资源型地区产业结构升级优化的制度创新——以延安市为例

市场力量主导的诱致性产业结构和诱致性制度变迁有可能因市场的自发性而使一个社会的经济脱离发展轨道,而政府力量主导的强制性制度变迁,有可能因其设计出来的制度不符合产业发展的规律,而使一个经济社会形成唯政府意志的产业结构。而将两种制度变迁相互间有机地结合起来,以自然演化(市场原则)的产业结构为基础,并配合政府遵从自然演化原则科学设计出的产业结构有可能达到产业结构的合理性标准。延安的能源化工产业在其产业结构中占有重要的地位,但目前产业集群尚未形成,三次产业结构也不尽合理,为此,要通过制度创新来推动产业结构的升级和优化。     

我国居民收入差距与消费需求关系研究

主要研究了收入差距对消费需求的影响。通过建立数学模型,从理论上推导了收入差距的扩大对消费需求的制约作用。在此基础上结合我国城镇居民收入与支出的相关数据,将人群按收入水平划分为高、中、低三组,实证分析高收入人群与低收入人群的收入和消费关系,并提出了相应的政策建议。     

网络经济条件下的产品内分工与模块化生产

产品内分工、模块化生产是与网络经济紧密联系在一起的，生产和供应过程不同工序、区段和环节在不同的空间完成，然后在同一个地方形成最终产品，这样的生产方式实际上就是网络经济条件下一种典型的生产方式，因而必须遵循网络经济条件下的规则，并且其本身也具有一定的规律性。本文就网络经济条件下产品内分工的根源、模块化生产的特征及作用进行了探讨，旨在加深对分工问题的认识以及获得解决一些现实经济问题的启示。     

浅析产业内贸易理论

随着各国经济发展和人均收入水平的不断提高,产业内贸易的比重越来越大。以“国际产品异质性”、“需求偏好相似”、“规模经济优势”三个原理为支柱的产业内贸易理论对此进行了有效的解释,并以一个全新的视角对国际经贸理论进行了发展和完善。掌握这一理论无疑对我国产业结构的调整和贸易政策的制定都有着积极的借鉴意义。     

数字时代企业环境审计模式创新——基于环保政策响应机制的研究

企业规避环保责任的机会主义行为导致政府环保政策成效不显著。基于利益相关者理论构建环保政策利益相关者模型,并从环保权力、责任和信息三个角度分析企业的环保政策响应机制。研究发现：由于消费者缺位以及信息不对称等因素的影响,企业的环保政策响应水平较弱。政府应将环保政策施加于消费者,通过消费者来约束企业的行为;审计主体应当转变现有的审计模式,运用数字技术,与消费者合作共同完成审计监督的工作。基于此,提出一种基于消费者需求引导的综合环保政策及新型企业环境审计模式,建议政府应重视数字技术对产业的改造升级,充分考虑消费者的因素来制定环保政策并加大对企业污染数据实时监控的普及。     

An Econometric Estimation of Industrial Water Demand in France

This study investigates the structure of industrial water demand byestimating the derived demand for water on a sample of industrialestablishments located in the south-west of France. Productiontechnologies are represented by short-term variable cost functions andapproximated by a translog form. Industrial water use is modeled ashaving three components: the quantity of water bought to a waterutility, the quantity of autonomous water and the quantity of watertreated prior to use. We include in this framework water effluents,which are considered as a by-product of the production process, emittedby firms. Each of the three water components is treated as a separateinput and all are estimated as a system of simultaneous equations. Themodel is estimated on a sample of 51 industrial plants in the Girondedistrict observed from 1994 to 1996 using Seemingly Unrelated Regression(SUR) and Feasible Generalized Least Squares (FGLS). Results ofestimations show that industrial firms are sensitive to water priceinputs. Network water elasticity is estimated at –0.29. It variesfrom –0.10 to –0.79 according to the type of industryconsidered. Autonomous water price elasticity is not significant.Elasticity for treated water is evaluated at –1.42 at themean-sample and varies from –0.90 to –2.21 according to theindustry considered.     

Carbon Taxes and Joint Implementation. An Applied General Equilibrium Analysis for Germany and India

Germany has committed itself toreducing its carbon emissions by 25 percent in2005 as compared to 1990 emission levels. Toachieve this goal, the government has recentlylaunched an environmental tax reform whichentails a continuous increase in energy taxesin conjunction with a revenue-neutral cut innon-wage labor costs. This policy is supposedto yield a double dividend, reducing both, theproblem of global warming and high unemploymentrates. In addition to domestic actions,international treaties on climate protectionallow for the supplementary use of flexibleinstruments to exploit cheaper emissionreduction possibilities elsewhere. One concreteoption for Germany would be to enter jointimplementation (JI) with developing countriessuch as India where Germany pays emissionreduction abroad rather than meeting itsreduction target solely by domestic action. Inthis paper, we investigate whether anenvironmental tax reform cum JI providesemployment and overall efficiency gains ascompared to an environmental tax reformstand-alone. We address this question in theframework of a large-scale general equilibriummodel for Germany and India where Germany mayundertake JI with the Indian electricitysector. Our main finding is that JI offsetslargely the adverse effects of carbon emissionconstraints on the German economy. JIsignificantly lowers the level of carbon taxesand thus reduces the total costs of abatementas well as negative effects on labor demand. Inaddition, JI triggers direct investment demandfor energy efficient power plants produced inGermany. This provides positive employmenteffects and additional income for Germany. ForIndia, joint implementation equips itselectricity industry with scarce capital goodsleading to a more efficient power productionwith lower electricity prices for the economyand substantial welfare gains.     

A New Approach to Random Utility Modeling using the Dirichlet Multinomial Distribution

In this paper we introduce a new econometricapproach to analyzing recreational site choicedata, the Dirichlet multinomial model. Thismodel, which nests the standard conditionalmultinomial logit model, can accommodateover-dispersed data and may provide moreefficient estimators of coefficients andconsequent welfare measures than the standardconditional logit model, which is so widelyused in the Random Utility Model approach torecreation demand. We illustrate thisDirichlet approach using a data set of rockclimbers in Scotland, and study the impacts onper-trip consumers surplus of alternativemanagement strategies for popular rock climbingsites. Results show that the Dirichletmultinomial approach produces coefficient andwelfare estimates having smaller samplingvariability in this case. We also compareclassical welfare measures with their posteriorequivalents, which allow for welfare changes tobe dis-aggregated.
