浅析现阶段我国收入分配中的公平问题

现阶段,我国收入差距不断拉大,收入分配不公平的问题已经凸现,严重影响了社会主义和谐社会的发展.要解决收入分配存在的问题,必须正确理解公平原则,切实有效地采取措施调节收入分配,在分配领域特别是在再分配领域中更加注重公平,逐步实现公平与效率有机的、动态的结合,促进社会的和谐发展.     

比较优势理论与农业区域专业化发展——以福建省为例

应用比较优势理论探讨农业区域专业化发展问题。理论推导得出,按照区域农产品生产优势来选建农业专业化部门能够实现农业增效,提高农业生产整体水平。以福建省为例,采用区位商和平均值法分析了主要农产品生产比较优势。结果表明,福建省多数县份的一种或几种农产品具有显著比较优势,农业生产的区域专业化已现端倪。但目前大多数县份主导产品不显著,专业化生产与农业资源禀赋不相协调。按照县域农产品的比较优势创建农业专业化部门,将是福建省解决"三农"问题和协调县域之间经济发展的有效途径。     

2002～2005年间我国不同地区高校科技创新效率比较研究

利用SPSS13.0对2002～2005年间我国各省、市、自治区高校科技创新活动进行了聚类分析,并采用DEA的CCR模型对这4年中我国各省、市、自治区高校科技创新过程中经费支出,以及人员投入的效率问题进行了比较研究,结果发现有24个地区DEA有效,6个地区非DEA有效。最后给出了非DEA有效地区的改进方向。

Order imbalance and stock returns: Evidence from China

We investigate the relation between daily order imbalance and return in the Chinese stock markets of Shenzhen and Shanghai. Prior studies have found that daily order imbalance is predictive of subsequent returns. On the two Chinese exchanges we find the autocorrelation in order imbalances is similar to that of the New York Stock Exchange as reported by Chordia and Subrahmanyam [Chordia, T., & Subrahmanyam, A. (2004). Order imbalance and individual stock returns: Theory and evidence. Journal of Financial Economics, 72, 485–518]. We also find a strong contemporaneous relation between daily order imbalances and returns. However, we do not find evidence that order imbalances predict subsequent returns. We attribute the difference in predicative power to differences in trading mechanisms on the two exchanges and to differences in the share turnover rates.     

A Stochastic Frontier Production Function with Flexible Risk Properties

This paper considers a stochastic frontier production function which has additive, heteroscedastic error structure. The model allows for negative or positive marginal production risks of inputs, as originally proposed by Just and Pope (1978). The technical efficiencies of individual firms in the sample are a function of the levels of the input variables in the stochastic frontier, in addition to the technical inefficiency effects. These are two features of the model which are not exhibited by the commonly used stochastic frontiers with multiplicative error structures.An empirical application is presented using cross-sectional data on Ethiopian peasant farmers. The null hypothesis of no technical inefficiencies of production among these farmers is accepted. Further, the flexible risk models do not fit the data on peasant farmers as well as the traditional stochastic frontier model with multiplicative error structure.     

Productivity Growth, Efficiency and Outsourcing in Manufacturing and Service Industries

This paper is a survey of recent contributions to, and developments of, the relationship between outsourcing, efficiency and productivity growth in manufacturing and services. The objective is to provide a thorough and up–to–date survey that provides a significant discussion on data, as well as on the core methods of measuring efficiency and productivity. First, the readers are introduced to the measurement of partial and total factor productivity growth. Different parametric and non–parametric approaches to the productivity measurement in the context of static, dynamic and firm–specific modelling are discussed. Second, we survey the econometric approach to efficiency analysis. The issues of modelling, distributional assumptions and estimation methods are discussed assuming that cross–sectional or panel data are available. Third, the relationship between outsourcing and productivity growth in manufacturing and services is discussed. The correspondence between a number of hypotheses and empirical findings are examined. Examples of varieties of relevant empirical applications, their findings and implications are presented. Fourth, measurement of inputs and outputs in manufacturing and services are discussed. Finally, to promote useful research, a number of factors important to the analysis of outsourcing, efficiency and productivity growth in the service sector are summarised.     

稳健财政政策下国债的适度规模与管理

2005年起,我国开始实行稳健的财政政策,经济运行方式发生了变化,国债政策作为以前积极财政政策调节经济方向的重要工具也应采取相应变化以促进经济向前发展.由此加强我国国债规模管理,不仅应从总体上缩小国债规模,更应该注重国债资金的使用效率,对其加强监督管理.

广东省流通服务业资本边际生产率变动趋势研究

为研究资本要素在广东省流通服务业中的使用和配置效率问题,首先运用永续盘存法估算出历年广东流通服务业中各行业以不变价计算的固定资本存量,再以收入法估算出历年行业的资本边际贡献份额,并计算了行业的不变价增加值,在此基础上估计出1993年~2003年10年间各行业的资本边际生产率。结果表明:这些行业的资本边际生产率在这10年间呈明显的上升趋势,即资本的使用效率在提高,但交通运输业的资本边际生产率偏低,且行业间的资本边际生产率差异增大,行业间资本的配置效率下降。
