The Application of Mathematical Programming Approaches to Estimating Container Port Production Efficiency

Container terminal production is both an important and complicated element in the contemporary global economy. This paper aims to evaluate the efficiency of the world’s most important container ports and terminals using the two alternative techniques of Data Envelopment Analysis (DEA) and the Free Disposal Hull (FDH) model. The results give an insight into the current efficiency ranking of the world’s major container ports and terminals. They also confirm expectations that the available mathematical programming methodologies lead to different results and that appropriate variable definition of input and output factors is a crucial element in meaningful applications of DEA and FDH. It is also concluded that the availability of panel data, rather than cross-sectional data would greatly improve the validity of the efficiency estimates derived from all the mathematical programming techniques applied.JEL Classification:C61, D24, E23, L23, L25, L92

我国钢铁企业绿色营销的创新思考

随着全球资源短缺及环境恶化的日趋加剧,我国钢铁企业的生存环境日趋严峻。建立以循环经济理论为依托的绿色营销模式是我国钢铁企业应对市场挑战的必然途径,但目前我国钢铁企业的绿色环保意识较淡薄,缺乏绿色营销理念及理论体系的支持,远远落后于西方发达国家的同行,大大制约了其在国际市场上的竞争力。

"十一五"时期高技术改造传统产业的战略研究

“十一五”时期,是我国对外开放和经济发展都进入一个前所未有的全新发展的时期,对外开放与全面、协调和可持续发展,要求高技术改造传统产业战略在统筹国内外经济发展的基础上,着重实现以下几个重大转变。一、战略着眼点:从立足国内转向立足国际,推动新的国际分工体系形成所谓国际化,是通过适当的国际分工增加和实现一国的比较利益,其核心是实现和加快工业化和推动经济快速增长。发展中国家的国际化本身就是一种发展战略,而且某种程度是一种赶超型发展战略。立足国际化,意味着发展中国家要主动参与经济全球化,通过这个过程缩小与发达国家的…     

The rationality and efficacy of decisions under uncertainty and the value of an experiment

Summary A decision maker faces a known prior distribution over payoff relevant states. We compare the expected utility of this individual under two scenarios. In the first, the decision maker makes a choice without further information. In the second, the decision maker has access to an experiment before choosing an action. However, the decision maker does not know the true joint distribution over states and messages. The value of the experiment as measured by the difference in the two utility levels can be negative as well as positive. We give a condition which is necessary and sufficient for the experiment to be valuable in our sense, for any decision problem.An earlier version of this paper was circulated under the title Noisy Bayes Updating and the Value of Information. We have gained from the comments of Stephen Coate, John Geanakoplos, Larry Samuelson, Timothy Van Zandt and seminar participants at Harvard Business School, Princeton, Boston University, the international conference on game theory at Stony Brook 1992 and the Winter meeting of the Econometric Society at Anaheim 1993.

领导风格与员工工作态度——互惠和信任的中介作用的实证研究

互惠和信任是社会交换的普适准则。本文基于社会交换理论，以中国境内各类企业972位管理人员为样本，试图研究领导风格与员工工作态度之间的关系，尤其是组织与员工间的互惠和员工的组织信任在其中的中介作用。在初步研究的基础上，本文对变革型领导、事务型领导、广义互惠、平衡互惠、员工的组织信任、组织承诺和离职意愿各概念进行了系统的探索性分析和验证性分析，接着检验了这七个核心概念的区分效度。研究结论表明：（1）变革型领导不仅直接对员工的组织信任和组织承诺产生作用，而且通过组织对员工的广义和平衡互惠使员工产生对组织的信任，从而提高员工的组织承诺和降低员工的离职意愿；（2）事务型领导仅仅通过互惠对员工的组织信任和组织承诺产生作用；（3）广义互惠直接影响员工的组织承诺，平衡互惠通过组织信任影响员工的组织承诺。研究结论告诉我国企业领导者，首先，尽可能锻炼自己，努力成为变革型领导者。其次，要努力塑造互惠和信任的企业文化，并且特别着重于建设广义互惠的企业文化和制度环境。     

我国反腐败工作的现状与进展

反腐败问题是现代社会所面临的一个共同课题。我国反腐败现状可以从监督、领导干部廉洁自律、查办违法违纪案件、纠正损害群众利益的不正之风和源头治理等五个方面来进行深入了解和总体把握。在此基础上,针对我国反腐败理论研究的薄弱环节,从“腐败”的概念和类型划分、反腐败的领域范围、预防腐败以及制定反腐败的专门法律等方面探讨和研究反腐败的基本问题,以便促进我们对反腐败工作的认识,并推动相关的工作。     

Strategic Reaction of Vertically Integrated Firms to Downstream Entry: Deterrence or Accommodation

The purpose of this paper is to analyze strategic behavior of vertically integrated firms when there is downstream entry, taking into account the balance between competition in the market and competition for the market. This analysis can serve to explain diverse distributional structures, including the coexistence of vertically integrated firms and independent retailers. And it shows that the relative efficiency of downstream entrants and the level of competition among incumbents are two major factors in determining equilibrium configuration.     

企业人力资产确认及其计量模型改进

本文认为,企业人力资产的确认与计量应与人力资源管理紧密结合,同时应将“区别考评制度”引入对企业人力资产的确认及对人力资源价值的计量中,并对原有个体和整体人力资源价值的计量模型进行了改进。
