基于合作对策的工程项目集成化管理利益剩余分配模型研究

文章借鉴制造业虚拟组织的利益分配机制,结合工程项目集成化管理实际,分析了工程项目集成化管理利益剩余的产生渠道,确定了工程项目集成化管理利益剩余的评价指标;根据利益剩余种类的不同,运用合作博弈理论,构建了基于Nash谈判模型的工程项目集成化管理利益剩余总量分配模型,以及基于Shapley值的工程项目集成化管理无形利益剩余分布模型,并基于两种模型给出了确定工程项目集成化管理利益分配方案的方法;最后,通过一个算例仿真验证了模型的可行性和合理性。结果表明,该模型能够综合考虑工程项目集成化管理的直接经济利益剩余和无形利益剩余,计算简单,结果合理,是一种效果较好的工程项目集成化管理利益剩余评估分配方法。     

THE OPTIMAL CAPACITY EXPANSION POLICY FOR A MULTI-PRODUCT FIRM UNDER A DYNAMIC FRAMEWORK *

An optimal capacity policy model for a multi-product firm is constructed in a dynamic programming framework, which assumes the following: all current inputs have a perfectly competitive market, all capital resources are limitational, though capable of being utilized in more than one production line and there is a marketing cost function of a specified type for the outputs sold.     

资源节约型社会评价指标体系设计及山东省的实证研究

根据资源节约型社会的内涵与特征,遵循指标体系的建构原则,建立了资源节约型社会评价指标体系,该指标体系包括4个层次和31个指标,所有指标可归纳为四个领域:减量化、再循环与无害化、资源节约支撑能力、资源节约发展态势。根据以上指标体系,对山东省1997年至2006年的资源节约状况进行了综合评价。结果显示:虽然山东省在减量化、再循环、无害化方面取得了一定成绩,资源节约水平逐年提高;但由于资源节约支撑能力薄弱,因此制约了山东省资源节约水平的进一步深化。     

纺织业引进技术消化吸收与创新模式的探讨

若能更好解决引进技术消化吸收与创新的矛盾和问题,将有助于纺织业整体实力的提高。研究引进技术消化吸收与创新的可行性、实操性和持续性,为行业发展提供技术、经济指标,构建纺织业创新模式的新理念,提出纺织业"引进、吸收、创新"的发展模式,避免引进技术的盲目性,对行业具有较大的借鉴价值和指导意义,并能获得良好的社会、经济效益。     

Multidimensional Bargaining Under Asymmetric Information

A buyer with private information regarding marginal valuation bargains with a seller to determine price and quantity of trade. Depending on parameter values, a high‐valuation buyer wants either to reveal information to create value or to conceal it to capture value. In the first case, equilibrium trades are efficient. In the second case, the low‐valuation buyer purchases less than her efficient quantity, and there can be a one‐period delay in trade. The quantity distortion is the only inefficiency that persists when time between offers approaches zero. There exist equilibria that are independent of the seller's prior beliefs.     

Determinants of Trade Misinvoicing

Trade misinvoicing should be seen as an element of de facto capital account openness. Traditional explanations for trade misinvoicing??high custom duties and weak domestic economies??are less persuasive in a world of high growth emerging markets that have low trade barriers. We construct a 53-country data set over a 26?year span, covering both industrialized and developing countries, to study the phenomena of export and import misinvoicing. Capital account openness, differentials in interest rates, political stability, corruption, indebtedness and the exchange rate regime are identified as factors related to misinvoicing.     

我国金融资源的城乡配置问题研究

我国金融资源的城乡配置问题是城乡二元结构在金融领域的突出反映。总结了我国金融资源城乡配置的主要问题,在回顾文献研究的基础上,系统分析了我国金融资源城乡配置的状况,指出了统筹城乡发展是实现我国金融资源城乡合理配置的出路,并具体提出了统筹城乡金融制度建设、统筹城乡金融市场建设、统筹城乡金融环境建设等三方面的政策建议。     

International Trade and Manufacturing Employment: Is India following the Footsteps of Asia or Africa?

The Indian manufacturing sector has rapidly increased its integration with the world economy since the 1991 trade reforms. We examine whether trade integration created or destroyed jobs in the Indian manufacturing sector, and compare India's employment outcomes with four other countries—Bangladesh, Kenya, South Africa, and Vietnam. We find that the impact of international trade on manufacturing employment seems to be similar to those found for the two African countries rather than the two Asian countries, a surprising result for a country with an apparent comparative advantage in labor-intensive manufacturing goods, and a large excess supply of unskilled labor.     

一种基于正交匹配追踪的压缩感知信号检测算法

针对当前压缩感知信号检测算法没有充分利用稀疏系数幅值信息的不足,提出了一种新的检测算法。从正交匹配追踪算法切入,通过深入分析归一化残差的变化信息,提出归一化余差概念,建立了一种基于归一化残差和归一化余差二维判决的信号检测算法。仿真结果表明,算法的有效检测阈值区间随着信噪比的降低而不断减小,且在信噪比为-8 dB、压缩比为0.25时,该算法的检测概率仍能满足要求,具备较好的适应性。     

“后危机”时代人民币主动国际化政策研究

2007年次贷危机爆发至今,对世界经济发展造成极大冲击。欧美等主要经济体都遭受到不同程度的破坏,经济发展放缓甚至倒退。而我国在积极的财政政策和稳健的货币政策带动下,率先走出了此次危机。近期中央出台的一系列措施,旨在抓住机遇推行早已提上日程的人民币国际化。本文以后危机时代这一非常时期为参照,探究了人民币首次主动寻求国际化的政策转向,即从被动国际化转向主动区域化,并提出相关政策建议。
