增加值率下降意味着什么

增加值率是从总体上度量一个经济体投入产出效益的综合指标。中国的增加值率一直在下降,表明中国经济增长的质量在下降。本文定义了中间投入贡献系数,给出其与增加值率的关系,通过分析中间投入贡献系数的变化本文得出,新增加中间投入品的贡献系数下降是造成总体中间投入贡献系数进而增加值率下降的原因。接着本文利用变参数经济计量模型,测算了改革开放以来国内中间投入和进口中间投入的贡献系数的数值和变化情况,并就提高增加值率的可能方面进行了探讨。

评价指标体系在经济责任审计中的应用

将评价指标体系应用于经济责任审计可避免审计的随意性和不同审计人员审计的不一致性,本文以高等院校为主体从合法合规性、效益性、目标性等方面设计了经济责任评价指标体系。     

Growth at the EU periphery: the next enlargement

In 2004, 75 million people are scheduled to become EU citizens, making this the largest round of expansion of the Western European club to date. Of the 10 new entrants, 8 are former socialist economies, for which membership in the EU represents the coronation of an effort began with the fall of the Berlin wall in 1989. Based on their recent economic performance, the Central and Eastern European countries appear to be well on their way to successfully integrate in the Western European club, while the Baltic Republics still lag behind. The gap between the two groups emerges when we consider the adjustment of the production structure, the composition of trade and FDI flows, and income distribution. The evidence we review appears to support the role of institutional quality to facilitate integration in the world market and overall economic performance.     

Cointegration, causality and export-led growth in Mexico, 1895–1992

Cointegration and Granger-causality tests show that real exports and real GDP in Mexico over 1895–1992 were cointegrated and there was a significant and positive Granger-causal relationship running from exports to economic growth.     

The Nonparametric Approach to Applied Welfare Analysis

Changes in total surplus are traditional measures of economic welfare. We propose necessary and sufficient conditions for rationalizing individual and aggregate consumer demand data with individual quasilinear and homothetic utility functions. Under these conditions, consumer surplus is a valid measure of consumer welfare. For nonmarketed goods, we propose necessary and sufficient conditions on input market data for efficient production, i.e. production at minimum cost. Under these conditions we derive a cost function for the nonmarketed good, where producer surplus is the area above the marginal cost curve. We are greatful to helpful remarks and comments of the referees and the editor.

Policy Discrimination with and without Interpersonal Comparisons of Utility

Can the Pareto criterion guide policymakers who do not know the true model of the economy? If policymakers specify ex ante preferences for agents, then Pareto improvements from a distorted status quo are usually possible, and with more commodities than states, one can implement almost every Pareto optimum. Unlike the standard second welfare theorem, planners cannot dictate allocations: agents must trade. Unfortunately ex ante preferences impose interpersonal comparisons. If policymakers merely aim to maximize some social welfare function then optimal policies form an open set; hence small changes in the environment do not necessitate any policy response. Planners with symmetric information about agents can sometimes intervene without making interpersonal comparisons.     

新农村建设:一个政治经济学视角的解析

新农村建设是对城乡经济社会发展不平衡的一个积极回应,它包含经济增长和社会发展两个层面.从政治经济学视角出发,在经济增长方面,户籍、土地、保障等制度性因素制约到农村劳动力的有效流转,从而对劳动生产率提升和农业发展产生负面影响;在社会福利方面,农民的数量优势没有转化为谈判优势,对市场价格和政策制定的影响力较小,其社会福利获取以及发展程度处于不利地位.据此,新农村建设必须对相关制度性、组织性因素进行完善和改革,部分农民的真正流转和留守农民的自发组织将尤其重要.     

服务业和制造业企业法人绩效比较

本文运用累积分布曲线分析经济普查数据发现,服务业和制造业企业法人相比,前者装备一个劳动力所需的资产量更多;前者的财务和经济效益比后者差;进入前者的投资门槛不比后者低。这些经验证据与大量理论和政策分析中的流行认识存在巨大反差。本文的经验发现提醒我们:在目前国情之下,大量资金投入服务业(尤其是生产性服务业和现代服务业)企业的机会成本,大于投入制造业企业的机会成本。所以,服务业发展应该分门别类、实事求是地推进。把发展服务业作为产业结构“升级”和经济增长方式转变重要途径的看法,也需要进一步深入分析。
