摘要撰写“标准”新解与翻译探微

针对国内学术期刊英汉摘要写作和翻译中的不足,对比分析了国际标准（ISO）214—1976（E）和国家标准GB6447—1986中的摘要写作规范。结果发现：两“标准”实质上确认了摘要的文体、语篇和体裁特征;国家标准等效地采用了国际标准,“规则”不同源于英汉民族思维差异。汉译英摘要应参照国际标准规范,符合英文表达习惯、保持中英文摘要的基本一致并要与时俱进。要使摘要起到其应有的作用,从“规则”本身人手是关键。     

中国的最优化动态IS-LM模型构建与应用

传统的IS-LM模型由于存在许多缺陷一直以来都备受批评。理性预期革命之后出现的基于跨期动态最优化的IS-LM模型却能够很好地克服传统的缺陷,逐渐受到当代宏观经济学家的青睐。本文尝试在最优化IS-LM基本模型的基础上,引入对定期存款的配置行为,加入政府和国外部门,将模型拓展为四部门三资产模型,然后利用中国数据采用理性预期的方法对参数进行估计,并解释了方程系数的含义。最后对于模型如何实现动态化用以描述经济的演化作了一些探讨。     

CEV模型的单位根检验研究

CEV模型（Constant Elasticity of Variance Model）作为常用的利率模型,在实证分析中得到了广泛运用,但是其单位根检验一直被忽略或者被默认可以使用迪基一富勒检验。本文首次运用Box—Cox变换的技巧,针对CEV模型的单位根检验问题,找到了合适的统计量并且证明其渐进分布存在,然后通过蒙特卡罗方法求出了该统计量的分布表。得到了在大样本的情形下可以沿用迪基一富勒检验,但在小样本的情形下与迪基一富勒检验有所偏差的结论。     

废旧机电产品再循环模式研究

能否有效处理日益增加的废旧机电产品对我国经济的可持续发展有着重要的影响。文章从产品的角度提出基于循环经济的“3个循环”的概念,并在分析现有废旧机电产品循环模式的基础上提出第二循环模式,同时给出了相应的产品剩余寿命评价模型。     

上市公司股权结构对投资决策的影响实证研究

大量研究表明股权结构影响公司价值。从价值的创造过程看，股权结构首先影响公司投资，从而影响公司价值。解释股权结构如何影响公司投资具有非常重要的意义。通过计量经济方法对我国上市公司股权结构如何影响公司投资的研究表明，国有股东控股的公司存在过度投资行为，而非国有股东控股的公司能够较好地控制过度投资。我国国有控股公司现有股权结构导致了扭曲的公司投资决策。     

我国进一步推进水价改革的思考

随着工业化和城市化的发展,供水成本的不断上升和水资源的日益稀缺已经成为经济社会发展的一大障碍。水价政策能够在解决这些问题上发挥重要的作用。无论是工业和服务业用水、城市居民用水还是农业用水,其价格都应该体现水资源成本、供水成本和环境成本。水价改革必须在确定保障正常生产生活的基本用水量的基础上,通过水资源成本和环境成本在水价格中的充分体现,兼顾水企业和用水主体的利益,达到节约用水和水资源环境可持续发展的目的。     

基于公平与效率均衡的城乡和谐

已有的对城乡和谐发展问题的研究大多将注意力集中在城乡和谐发展的途径方面,却忽视了对城乡和谐衡量标准的研究.本文从公平与效率统一(均衡)的视角来解析城乡和谐的标准以及城乡和谐演进的机制,并构建了一个基于公平与效率均衡的城乡和谐发展模型.该模型揭示,城乡和谐是公平与效率均衡的函数,市场机制与政府制度的相互配合共同促进城乡和谐发展.     

The relationship between business diversification and productivity: considering the impact of process innovation at different corporate life cycles

This paper investigates the link between a firm's process innovation (PI) and its segment productivity at different life cycles. The results show that business diversification is negatively associated with a firm's productivity, and further reveal that a firm's PI moderates the above relationship. In addition, the corporate life cycle literature builds blocks for this study to explain that the involvement of administrative costs varies across life cycles when diversified firms get mature and bigger. Our empirical evidence indicates that the potential costs of a complex organisational structure contingent on business diversification at a firm's mature life cycle could be alleviated by the conduct of process innovation. As process innovation at different life cycles may alter managerial incentive that leads to different firm performance, the managerial implication is that diversified firms should appropriately engage in process innovation to prevent unfavourable liability from the development of their businesses.     

Complementarity and the Measurement of Individual Risk Tradeoffs: Accounting for Quantity and Quality of Life Effects

This paper considers the factors responsible for differences with age in estimates of the wage compensation an individual requires to accept increased occupational fatality risk. We derive a relationship between the value of a statistical life (VSL) and the degree of complementarity between consumption and labor supplied when health status serves as a potential source of variation in this relationship. Our empirical analysis finds that variations in an individual’s health status or quality of life and anticipated longevity threats lead to significant differences in the estimated wage/risk tradeoffs. We describe how extensions to the specification of hedonic wage models, including measures for quality of life and anticipated longevity threats, help to explain the diversity in past studies examining how the estimated wage–risk tradeoff changes with age.
