论企业文化在塑造核心竞争力诸因素中的核心地位

本文借鉴7S模型分析了塑造企业核心竞争力的影响因素和途径,运用文献和案例论证了企业文化在塑造核心竞争力的各因素中居于核心地位,指出了塑造核心竞争力的途径是运用先进的企业文化培育和谐的7S体系。     

基于提前期和价格折扣的延迟交货和库存策略研究

研究了基于提前期和价格折扣的延迟交货和库存策略,其中的价格折扣是基于提前期的价格折扣,即当出现缺货而不能在既定的提前期内交货时,企业就会提供一个价格折扣,这时会有一部分顾客愿意等待,直到订单被满足,即延迟交货。其中,愿意等待延迟交货的比例跟提前期成反比关系,提前期的各部分都可以通过增加成本来实现压缩。     

Illicit drug markets and economic irregularities

Markets for illicit drugs present an interesting case study for economics, combining non-standard characteristics such as addiction and product illegality. One response has been to argue the generality of economic principles by suggesting that they apply even in the extreme case of markets for addictive substances, e.g., by showing that demand for illicit goods is responsive to price [1] [Reframing health behavior change with behavioral economics. Hillsdale, NJ:Lawrence Earlbaum Associates; 2000. p. 89-111.] and even by modeling addiction as rational [2] [J Political Econ 1988;96:675-700]. This paper sketches examples of an alternative reaction, focusing on idiosyncrasies of drug markets that might plausibly create counter-intuitive effects, including supply curves that slope downward because of enforcement swamping and/or a good serving as the only available store of wealth for its producer, demand reduction programs that increase demand, and consumption by “jugglers” possibly increasing rather than decreasing as prices rise. This analysis yields non-obvious policy recommendations; for example, source country control programs should concentrate on growing regions with a healthy banking sector.     

我国M_2/GDP的动态增长路径、货币供应量与政策选择

本文试图求解我国M2/GDP的动态增长路径,并对与此相关的金融政策选择进行分析。研究发现,我国M2/GDP的变动路径具有Logistic曲线的基本形状,将经历先加速上升后增长速度逐渐减缓,最终趋于稳定状态的变化过程。本文估算了我国M2/GDP的增长上限及其变化拐点。研究还发现,M2/GDP的上升并不必然意味着通胀压力加大,只有M2/GDP偏离动态增长路径时,才会对通货膨胀产生影响。据此本文估算了2005年货币供应量的合理区间。本文认为,应继续实施稳健货币政策,合理确定货币总量增长速度,继续推进体制性改革等措施确保经济金融的稳定运行。     

Seasonal decomposition and forecasting of telecommunication data: A comparative case study

In this paper, forecasting models for the monthly outgoing telephone calls in a University Campus are presented. The data have been separated in the categories of international and national calls as well as calls to mobile phones. The total number of calls has also been analyzed. Three different methods, namely the Seasonal Decomposition, Exponential Smoothing Method and SARIMA Method, have been used. Forecasts with 95% confidence intervals were calculated for each method and compared with the actual data. The outcome of this work can be used to predict future demands for the telecommunications network of the University.     

The coevolution of firms and their knowledge environment: Insights from the pharmaceutical industry

What are the most effective learning strategies for firms given the characteristics of their knowledge environment? This paper addresses this question by documenting the major changes in the knowledge environment of the pharmaceutical industry, with a particular emphasis on the period since the emergence of biotechnology, and discussing the related changes in the learning strategies of established pharmaceutical firms. Both the historical analysis and a review of the empirical research on organizational learning and knowledge transfer reveal a strong emphasis of firms on external learning through interfirm collaborations and sourcing of external knowledge. This learning strategy seems to be driven by the speed, uncertainty, and dispersion of knowledge developments in the industry. Studying the connections between the knowledge environment and the effectiveness of organizational learning processes is important to understand organizational change and adaptation, and is an area of research that deserves further attention.     

企业平衡增长管理策略研究

企业平衡增长作为一种超越增长不足或增长过度的理想增长状态,几乎是所有企业追求的目标。然而,企业能否平衡增长不仅受企业经营和财务两方面诸多因素的制约,同时还与企业所处的发展阶段密不可分。根据平衡增长理论模型,结合企业不同发展阶段的特征,企业可以通过提高资产报酬率,改变企业的目标资本结构或股利政策,调整实际增长率等策略解决企业成长和成熟阶段平衡增长的矛盾。     

东亚汇率协调机制与中国的理性选择

1997年亚洲金融危机之后,汇率协调的重要性已在东亚各国政府及经济学界形成共识.对于如何建立东亚汇率协调机制,许多国家政府和经济学家都提出了解决方案,并进行了大量的实证研究.如东亚日元区方案、东亚美元本位方案、一篮子目标区爬升钉住方案、亚洲汇率机制方案以及编制亚洲货币单位方案等.但是,通过对比分析各种协调方案认为,目前在亚洲还不存在一种可行的稳定的汇率协调机制,因此,谋求人民币在亚洲地区作为关键货币的地位才是中国在东亚货币合作中的最大利益所在.     

企业同质性假设、异质性假设与企业性质

本文通过对企业同质性假设和异质性假设的进一步探讨,认为运用企业同质性假设的抽象方法可以合乎逻辑的解释企业的契约本质和企业契约的"规制或分配性",而企业异质性假设方法的运用可以理解企业的多样性和差异性,从而对企业契约的"生产性"做出令人信服的解释.企业契约理论和企业能力理论在事实上共同构成了一个有关企业性质认识的完整分析框架.     

企业生态位与竞争战略

本文提出了企业生态位的概念,并运用生态位理论对企业生态位宽度和企业生态位重叠的内涵、测度作了尝试性的探索.在一个环境资源有限的企业生态系统中,企业之间的竞争程度与其生态位重叠的程度成比例关系.企业不仅要选择恰当的生态位,而且要根据环境的变化对生态位作出及时、适当的调整和优化.企业可以通过生态位分离来实现生态位共生,从而避免由于生态位的严重重叠而引起的过度竞争.
