中国及各经济区工业企业效率的实证研究

文章利用数据包络分析（DEA）方法，对1998—2003年我国全国及各经济区工业企业的效率水平进行了实证研究。结果发现，这几年我国工业企业发展基本健康，但缺乏突破，东部地区的工业企业效率基本无变化，东北地区、西部地区的工业企业效率有所改进，中部地区情况有所恶化。进一步分析认为，中西部地区的工业企业均存在获利能力差的问题，其中，中部地区的工业企业还存在投入结构不合理的问题。     

我国地区产业结构调整及其效益分析

改革开放以来,我国四大地带产业结构的变动趋势大致相同,但东部各产业的劳动生产率和对经济增长的促进作用要明显优于中、西部和东北.目前四大地带产业排序已由二一三转变为二三一,接下来应促使第一产业的发展与农产品加工工业的发展相互适应,才能使区域的经济增长达到最佳效益.同时,鉴于各地带二、三产业对经济增长促进作用的大小同各产业从业人员的劳动生产率成正比,地区产业结构的调整还应注意劳动生产率的提高.     

效率与公平关系的物权法思考

在物权领域,浅层面的物权公平与物权效率并不矛盾.冲突存在于物权效率与高层面的社会公平之间,即物权效率自然发展导致起点不公平、机会不均等、结果不均衡.并且在这一交叉层面的"物权垄断"势能所产生的"马太效应"不可能熨平.通过物权社会化,让私人性物权效率提升为社会效率,则社会效率与社会公平能和谐一致.这种提升属政府管制时的限制,是在初次分配中重新界定权利,不是要素所有的分配,而且权利分配的财富调整功能优于再分配.     

H-O国际贸易理论的新兴古典分析--交易效率对国际贸易的影响

赫克歇尔一俄林的生产要素禀赋理论作为主流经济学派理论在国际贸易理论总体系中的影响力是巨大和深远的。而新兴古典贸易理论的发展，为解释国内贸易和国际贸易提供了一个统一的理论内核。这一理论的完美框架和强大的现实解释力引人瞩目。其理论的核心在于该理论独特的分析工具：超边际分析方法。采用新兴古典经济学的超边际分析法，引入交易效率，对赫克歇尔-俄林的生产要素禀赋理论进行新的分析，可以得出很多有价值的结论。     

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。

Towards an operational sustainability criterion

This paper examines the concept of sustainability and its implications for environmental policy analysis. It builds on the premise that present society holds a moral obligation to pass on a world of undiminished life opportunities to members of future generations. Maintaining life opportunities, in turn, can be achieved by maintaining or improving a diverse set of resources and capabilities that support a person's freedom to define and pursue her own conception of the good life. On an operational level, this framework points to the following guideline for environmental policy: Protecting the rights of future generations requires either the conservation of environmental resources or compensatory measures (including the provision of substitute technologies) that ensure the fair and proportionate sharing of net benefits over intergenerational time scales. In this framework, resource depletion is permissible only if (with reasonable certainty) it would generate a Pareto improvement relative to a baseline scenario involving strict resource conservation.     

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.     

The xistence of definitional economics--Stigler's and Leibenstein's war of the words

The inability to agree on definitions ultimately can condemneconomic analysis and debate to fruitless argumentation. Thesharp interchange between Stigler and Leibenstein did littleto clarify the issues surrounding the controversial theory ofX-efficiency. Given their conflicting agendas, discussion betweenthese two opponents consisted largely of talking at cross purposes.This paper examines the motivations of the two protagonistsas well as considering the impact such tactics have on economicdebate and discussion.     

Economic liberalization and welfare in a model with an informal sector

The paper reexamines the conventional results relating to inflow of foreign capital, removal of protectionism and structural reform programmes, in a small open economy in terms of a two-sector general equilibrium model with an informal sector. The paper shows that in the presence of labour market distortion and a protectionist policy, inflow of foreign capital may be desirable irrespective of the pattern of trade of the economy due to its favourable impact on welfare. But the welfare implications of tariff reductions and/or structural adjustment programmes, such as deregulating the formal sector labour market, depend crucially on the economy's trade pattern. The paper provides an answer to the question as to whether in a developing economy labour market reform and tariff reform should go hand-in-hand or whether one should precede the other for welfare improvement.
