Trade-offs in sulfur emission trading in Europe

How to implement emission trading is one question in the current negotiations on a new sulfur protocol in Europe. Whereas the current protocol stipulates a 30 percent uniform reduction, national emission ceilings included in the proposed new protocol imply differentiated reductions. In addition, emission and fuel standards are proposed. This paper examines the costs and environmental impacts of emission trading. Emission trading combined with regulations is a new element in the paper. Calculations using the RAINS (Regional Acidification INformation and Simulation) model suggest that overlaying emission trading on regulations not only reduces the cost savings but has beneficial impacts as well: ecosystem protection is not changed and significant decreases in environmental benefits for countries are largely avoided. Emission trading can also be used to decrease emissions and increase ecosystem protection. If combined with existing legislation, emission trading minimizes losses in expected environmental benefits for some countries, and most countries gain. However, the initial distribution of emission ceilings has to be used so that some countries are not confronted with higher costs. Trade-offs appear to exist between the use of emission trading to achieve cost savings on the one hand, and ecosystem protection and distributional equity on the other.     

基于成熟度模型的化工物流业(CL-CMM)研究

借鉴软件能力成熟度模型（CMM）,构建了化工物流业成熟度模型（CL-CMM）。将物流企业成熟度分为初始期、成长期、成熟期、成熟巩固期、成熟创新期;从分析各个等级的关键过程,为化工物流业发展提供决策依据。并用成熟度曲线表示了化工物流业发展所经历的过程。     

基于价值工程理论的房地产性价比确定

高性价比已成为房地产开发商和消费者共同追求的目标,然而长期以来性价比都只是定性描述。本文建立了房地产性能评价指标体系,并应用价值工程理论构建了房地产性价比的确定模型,将其定量化,最后通过一个案例进行了说明。     

基于动态能力理论的物流企业竞争力研究

应用动态能力理论，构建了物流企业竞争力测评指标体系和算法模型，在此基础上，应用上海和深圳证券交易所的数据样本。通过对5年时间内8家主营物流的企业竞争力的动态变化。深入分析和研究动态能力的各个关键要素对提升企业竞争力的动态影响，得到未来影响物流企业竞争力的要素已经从企业组织管理过程要素向企业定位和发展路径的要素转变，从而从时序的角度对多个物流企业竞争力的变化进行了实证研究。     

基于资源、知识与能力关系的组织核心能力内涵新界定

本文首先界定了资源、知识和能力的含义;然后分析了资源、知识和能力三者之间的关系;最后以此为基础重新界定了组织核心能力的内涵。     

企业推广排污权交易的可行性研究

排污权交易(Ernission trading)是一种基于市场(Market-based)的环境政策。本文坚持以科学的发展观，来研究经济发展与环境保护的协调关系，目的是实现环境资源和环境容量的可持续利用。本文分析了企业的排污行为决策，并将环境资源和环境容量的稀缺性纳入排污权交易价格之中。通过价格这个经济杠杆去调节人们对环境资源和环境容量的利用，反映于企业为其排污行为所作的选择，进而论述企业推进排污权交易的可行性。     

Short sellers and insider trading profitability: A natural experiment

We examine the impact of short sellers on insider trading profitability using a natural experiment of a pilot program which relaxed short-selling constraints for randomly selected pilot stocks. We find that pilot firms experienced a significant decrease in insider trading profitability during the pilot program. The results are more pronounced for the pilot firms with poor information quality, and for the pilot firms without corporate restrictions on insider trading. Our evidence suggests that short sellers serve an important market disciplinary role by reducing insider trading profitability.     

从外部性控制策略分析主要环境经济手段的异同

随着世界经济的发展,环境污染问题日益严峻。环境污染是最典型的负外部行为。本文分析了西方经济理论中关于控制环境方面负外部性两种策略的分歧,对比了以这两种策略为理论渊源的排污收费制度和排污权交易制度的异同及各自的适用条件。
