An Improved Splitting Method

In this paper, an improved splitting method, based on the completely square-conservative explicit difference schemes, is established. Not only can the time-direction precision of this method be higher than that of the traditional splitting methods but also can the physical feature of mutual dependence of the fast and the slow stages that are calculated separately and splittingly be kept as well. Moreover, the method owns an universality, it can be generalized to other square-conservative difference schemes, such as the implicit and complete ones and the explicit and instantaneous ones. Good time benefits can be acquired when it is applied in the numerical simulations of the monthly mean currents of the South China Sea.

经营性公路合理回报测算方法研究

针对经营性公路项目的合理回报目前法律上没有明确规定,社会上各方认识不统一的问题,研究提出了经营性公路合理回报的衡量指标——合理收益率,明确了合理收益率的考核模式,并对确定的考核模式,给出了测算合理收益率区间上限和下限的具体方法。最后,运用提出的测算方法,借助于经营性高速公路项目进行了实证分析。根据研究结果,建议经营性高速公路项目的合理收益率上限值取10.0%,下限值取相应年份的无风险收益率。测算结果为经营性高速公路项目的投资及行业收益监管提供了参考依据。

Externalities as Compensatory Criteria of Compulsory Expropriation Actions

Ownership/private property and property inheritance are concepts well-established and constitutionally protected in our modern societies.Nevertheless,numerous provisions in the national legal framework enable the states to expropriate individual private goods under certain severe circumstances through compensation prerequisites.The present manuscript presents a short comparative study of the constitutional articles of many countries,regarding expropriation actions,examines the compensation techniques employed,and interrelates expropriation implementation with economic analysis methods and experimental economics.Furthermore,this paper states that the current Greek expropriate methods consist of an economic disturbance and externality in economic terms.

作为社会发展之动力源的分工——分工理论何以式微?如何复兴?

劳动分工是提升社会生产力和组织有效性的微观基础,是经济增长和社会发展的动力之源,从而在政治经济学尤其是古典政治经济学中一直占据核心地位。但是,随着边际革命将研究对象从组织转向个体,分工理论就逐渐式微乃至消失了。即使奥地利学派关注社会分工问题,也主要是阐发自发市场的社会分工,而不是探究分工效率的来源,更没有剖析制约分工的因素。其根本原因就在于现代主流经济学的分析思维和分析方法:(1)在研究思维上,现代主流经济学的抽象还原思维不适合分析以异质性个体为基础的劳动分工;(2)在研究方法上,现代主流经济学的边际分析方法不适合分析基于内生优势的劳动分工。正因如此,现代经济学要重新研究劳动分工问题并有实质性推进,就需要寻求方法论的改变。
