DESIGNING ORDER‐BOOK TRANSPARENCY IN ELECTRONIC COMMUNICATION NETWORKS

A significant fraction of trade in stock exchanges (e.g., Euronext and NASDAQ) involves ‘iceberg orders’, which are orders to sell or buy a certain number of shares with the caveat that only a part of that number be made public. This paper provides a normative justification for the lack of transparency in this kind of order: imperfect disclosure is shown to be a necessary feature of any optimal mechanism when the asset's potential buyers must incur a cost in order to become active and learn their valuations for the asset. This finding raises a caveat for regulation that seeks to mandate the open order book or otherwise increase the pre‐trade transparency of stock exchanges.     

Lead Time Management through Expediting in a Continuous Review Inventory System

We consider a continuous review inventory system where delivery lead times can be managed by expediting in‐transit orders shipped from the supplier. First, we propose an ordering/expediting policy and derive expressions for evaluating the operating characteristics of such systems. Second, using extensive numerical experiments, we quantify the benefits of such an expediting policy. Third, we investigate a number of managerial issues. Specifically, we analyze the impact of the number of expediting hubs and their locations along the shipment network on the performance of such systems and offer insights into the design of the shipment network. We show (i) a single expediting hub that is optimally located in a shipment network can capture the majority of cost savings achieved by a multi‐hub system, especially when expediting cost is not low or demand variability is not high; (ii) when expediting time is proportional to the time to destination, for small‐enough or large‐enough demand variations, a single expediting hub located in the middle of the shipment network can capture the majority of cost savings of an optimally located hub; and (iii) in general, hubs close to the retailer significantly drive down costs, whereas hubs close to the supplier may not offer much cost savings.     

基于碳减排调度的激励性厂网合作竞价机制设计

市场机制是建立碳减排长效机制的基本制度安排。现行的节能发电调度办法没有市场的价格发现功能,本文研究了基于碳减排调度的厂网合作竞价机制问题,并讨论了合作机制的最优参数。研究结果表明:合作竞价机制可以促进电力市场的稳定供给,优化市场运行指标,顺应发电调度政策的导向;合作竞价机制能够增加低碳机组的发电收益,提高发电商CO₂减排的积极性。期望该研究工作能为电力行业有效减排的实践提供方法依据。     

卢卡奇同一主客体思想研究刍议

卢卡奇在《历史与阶级意识》中提出的同一的主客体思想是理解卢卡奇思想的一个关键点,是理解《历史与阶级意识》的一个＂题眼＂。国内卢卡奇的同一的主客体思想研究是一个逐步深入的过程。同一的主客体思想是《历史与阶级意识》的线索性概念,它与此书中其它概念有着密切关系。     

基于P2P的智能交通信息平台构成及数据查询技术研究

智能交通系统（ITS,Intelligent Transportation Syslem）是现今社会公认的能比较全面实时有效地解决交通运输领域,特别是交通拥挤、道路阻塞、交通事故和车辆污染等问题的最佳途径。然而基于传统网络技术结构的智能交通信息平台存在着许多不足之处。将P2P网络peer—to—peer networks）技术应用于智能交通信息平台可以解决由于传统网络结构不足而引起的性能问题。     

能源效率、二氧化碳排放效率与经济增长的关系分析

本文运用协整理论和误差修正模型,对世界和中国1971-2007年的能源效率、1960-2007年的CO2排放效率以及相应年度的GDP数据进行分析。结果表明,世界的CO2排放效率和GDP之间存在协整关系,中国的能源效率和GDP之间存在协整关系,且GDP是能源效率的Granger原因,从短期来看,GDP与能源效率呈正相关关系。     

碳税的内涵、效应与中国碳税总体框架研究

碳税是基于激励的价格型碳减排政策工具,是使外部性内在化的庇古税。碳税能有效地减少二氧化碳排放,虽在短期内抑制经济增长,但中长期将有利于经济的健康发展。它能降低能源消耗,改变能源消费结构,但会扩大资本与劳动的收入分配差距。中国在碳税设计时,应以二氧化碳估算排放量为计税依据,采用定额税率,从量计征,开征之初实行每吨二氧化碳20元的低税率,以后渐次提高;同时,建立完善的减免与返还机制,注重与其他税种及其他碳减排政策工具的相互协调,以形成合力。     

3G时代我国通信运营企业体验营销体系策略研究

从体验营销：3G发展的战略性举措和现实性选择、体验营销：要求机制体制的动态创新、体制创新：体验营销成功的保障这三个方面,论述了在电信新业务推广的大背景之下,应该转换传统惯性的思维定式,果断建立新的营销体系、采用新的营销方式,促进电信新业务的发展。     

二语朗读的言语感知和输出

国内已有的二语朗读研究主要从音系的物理特性和二语习得中介语的角度来探讨学习者音系发展水平,却忽略了言语感知和输出对二语朗读发展水平的作用。研究表明,学习者是二语朗读的主体,二语朗读受到发青器官、认知水平和母语感知方式的制约;二语朗读在语音感知、情感感知和概念感知方面与母语者存在差别。二语朗读的本质是生理和认知的体验性,这一特性正是二语朗读听读说叠加教学模式构建的基础。     

落后农村治理中的离散化问题

对一个落后村庄——山西省平遥县A村的农民离散化状态进行了描述,指出导致落后农村农民离散化的原因有：乡村干部和农民的压力型联系几乎消失,村级组织运转经费不足,农民对村干部的不信任感增强,农民收入来源和价值观念的多元化,村民国民化倾向等。农民的离散化影响到了落后农村的有效治理,需要引起决策层的关注,并加以解决,从而推动落后农村的新农村建设和发展。
