An upper bound on the minimal total cost of the transportation problem with varying demands and supplies

In general cases, to find the exact upper bound on the minimal total cost of the transportation problem with varying demands and supplies is an NP-hard problem. In literature, there are only two approaches with several shortcomings to solve the problem. In this paper, the problem is formulated as a bi-level programming model, and proven to be solvable in a polynomial time if the sum of the lower bounds for all the supplies is no less than the sum of the upper bounds for all the demands; and a heuristic algorithm named TPVDS-A based on genetic algorithm is developed as an efficient and robust solution method of the model. Computational experiments on benchmark and new randomly generated instances show that the TPVDS-A algorithm outperforms the two existing approaches.     

Operational Risk in Financial Services: A Review and New Research Opportunities

We present a framework to describe and analyze operational risk in financial services from an operations management perspective, focusing in particular on process design, process management, and human behavior aspects. The financial services industry differs from other service industries in ways that affect the nature of the operational risks it is subject to. In recent decades, many books and papers have focused on operational risk in financial services; however, this literature has focused mainly on the conceptual and statistical aspects of operational risk management and not on its operational aspects. Operational risk in financial services has not received much attention from the operations management community. The framework presented here is based on the premise that operational risk in financial services can reap significant benefits from research done in the theory and practice of operations management in manufacturing industries as well as in other services industries. The objective of this study is to propose particular challenges and questions raised in the practice of operational risk management that may stimulate future research in this particular area of operations management.     

中国证券业总产出和增加值测算研究

 金融机构总产出和增加值的测算是一项基础性的研究工作。与传统测算方法不同,本文借鉴经济合作和发展组织（OECD）提出的使用者成本法,把证券业视为生产性服务活动,并结合我国的实际情况,从服务的角度初步提出了我国证券业总产出和增加值的测算框架。并提出了未来研究改进的方向。     

缺少的分享——喜马拉雅东部(中国云南西北部)作为“整体社会事实”的分享的仪式语言

中华人民共和国成立以前,云南西北部怒江、独龙江流域居住的独龙族、怒族等邻近族群之间存在着一种共通的"议式语言".这种仪式语言通过宗教祭祀活动以及分享杀牲后的肉食过程体现出来.在这一地域社会中,各种社会、政治和经济关系都依赖于这种仪式语言展开.虽然目前这种分享的仪式日渐式微,但分享的意识依然体现着族群内部的"社会结合"方式.通过独龙族仪式语言的个案分析,旨在与利奇关于克钦社会的"仪式语言"研究进行对话.     

Construction of bivariate and multivariate weighted distributions via conditioning

Weighted distributions (univariate and bivariate) have received widespread attention over the last two decades because of their flexibility for analyzing skewed data. In this article, we propose an alternative method to construct a new family of bivariate and multivariate weighted distributions. For illustrative purposes, some examples of the proposed method are presented. Several structural properties of the bivariate weighted distributions including marginal distributions together with distributions of the minimum and maximum, evaluation of the reliability parameter, and verification of total positivity of order two are also presented. In addition, we provide some multivariate extensions of the proposed models. A real-life data set is used to show the applicability of these bivariate weighted distributions.     

生态价值:基于马克思劳动价值论的一个引申分析

检视和比较中西方关于生态价值问题的研究文献,基于马克思劳动价值论,并将其引申扩展到探索生态价值的致思路径是:沿着人类社会生产力发展水平不断提升的线索,从经济系统、生态系统和生态经济系统考察商品总价值、生态总价值和商品价值总量之间的内在关联及其数量变化关系。随着人类社会生产力水平由低到高的提升,商品总价值、生态总价值和商品价值总量三者之间呈现由同向递增变动到无序变动、再到更高层次的同向递增变动的趋势。在中国当前经济社会发展面临严峻生态问题的状况下,重新认识和理解生态价值问题,将有利于改变当前衡量经济社会发展指标过度单一的局面,有利于转变人们对自然生态资源、生态环境的不合理开发和利用的传统发展理念,有利于有效推动自然资源定价和参与市场化治理,并为其提供理论基础,从而使自然生态环境能够被科学、合理、协调、可持续地开发和利用。     

中国旅游上市公司全要素生产率研究

旅游上市公司是旅游业发展的微观主体,其全要素生产率全面反映了该行业的实际经营效率和发展趋势。本文基于Malmquist指数探讨了20家中国旅游上市公司2004-2009年的全要素生产率。Malmquist指数及其分解结果显示:中国旅游上市公司Malmquist指数年均增长率为-0.4%,其中纯技术效率的增长显著,年均增幅为1.3%;时间跨度层面,中国旅游上市公司的全要素生产率的年度波动性较大。此外,样本中旅游上市公司Malmquist指数与营业收入增长率未能兼顾;2008-2009年度粗放型增长的特征显著。     

当前经济形势下财政货币政策调控的重点

现阶段我国宏观经济运行中,一方面存在着通货膨胀压力,另一方面,社会总需求结构失衡严重,消费、投资、出口之间的比例关系极为不协调。经济失衡的复杂性,使财政政策与货币政策的协调配合成为我国宏观调控面临的难题之一。因此,面对新的形势,确定当前宏观调控的重点,提高财政政策和货币政策配合的效果,通过两大政策的配合实现经济稳定增长、优化总需求结构。     

基于增长核算分析的中国经济增长来源研究

应用新经济增长理论的增长核算分析框架,研究中国改革开放以来,物质资本、人力资本和全要素生产率（TFP）对经济增长的贡献,以及产权结构、对外开放等制度变迁对TFP的影响。研究发现,改革开来以来,全要素生产率的增长是经济增长的主要推动力,其次是物质资本存量的贡献,而人力资本对经济增长的贡献最低,并且逐期下降。实证分析也表明,由于中国正处于经济转型期,用＂索洛剩余＂衡量的TFP的增长不能简单地理解为技术进步;所有制结构和对外开放等制度变迁是推动中国TFP增长和经济增长的十分重要的两个因素。     

算好财务账：破解大学发展规划执行困境

大学战略发展规划虽是高校发展的纲领性文件,但在实际执行过程中常无法有效执行。通过以算好“财务帐”为切入点,以国家“211工程”、优势学科创新平台项目重点建设高校Y大学为例,从分析该校“十一五”末期的财务状况,判断出“十二五”时期的主要经费收入与办学成本支出构成,推导出发展资金;同时,将发展资金与重点规划工作任务经费预算进行比较,在二者呈负相关系时建议及时调整战略规划、开源节流、筹集资金或加大学校发展“短板”投入和民生建设等,为破解大学发展规划编制实施困境提供参考。
