THE JOINT ARRIVAL AND DEPARTURE PROCESS FOR THE M/M/l QUEUE

We consider the M/M/1-queue and derive an explicit expression for the joint distribution of the number of arrivals and the number of departures in [0, t), given the number of customers initially present. The derivation is almost purely combinatorial, it avoids the use of generating functions, and immediately yields a simple probabilistic interpretation of the result.

论市场所有权

本文作者首次在国内外提出了市场所有权理论，作者认为，过去我们对企业微观产权（包括有形产权和无形产权）研究较多，而忽视了对这些微观产权赖以存在的基础和实现条件－－市场产权的研究。实际上，市场本身也有一个产权界定及其制度安排问题，本文在界定产权概念的内涵，本质与功能的基础上，认为市场产权由狭义市场所有权，市场使用权（经营权），市场占有权和市场收益权等四个要素构成，认为市场产权具有五个方面的基本特征；市场所有权的稀缺性，市场所有权的准资本属性；市场所有权的排他性；市场经营权的可转让性；市场所有权收益的可计量性等，市场产权具有三种基本形式；市场国家所有制；市场区域共享制；市场全球共享制等，虽然市场市场产权天生具有国家排他性，归一国政府所有，但市场经营可以转让，各种贸易战的实质是争夺市场经营权，控制权和收益权，区域经济一体化和经济全球化是市场经营经营权的有限互换和交叉分享。     

工程造价市场信息分析及其在线系统开发

了解和熟悉某地区的市场信息对工程造价咨询公司在该地区开拓市场及造价工程师在该地区从事业务十分重要。本旨在探讨如何利用当代信息技术开发一个高性能的信息系统，它能为造价工程师提供及时的、全面和准确的市场信息(以上海地区为例)。系统开发所用的方法是一种改进的生命周期法。按照该方法，首先对工造价市场进行系统分析。然后，基于系统分析的结果，对市场信息进行分类，并在分类的基础上用超本技术建立信息模型。最后，基于模型开发信息系统。     

Process implications of the use of the Internet in new product development: a conceptual analysis

New product development requires a long and detailed process with numerous activities such as product line planning, strategy development, concept generation and screening, business analysis, development, testing and validation, manufacturing development and commercialization. Furthermore, each of these activities has its own unique requirements, some requiring information collection from the market, whereas others requiring the collaboration of different people who are involved in the new product development activities. This paper investigates the Internet's role in these activities and develops research propositions. In addition, it discusses how the impact of the Internet might change based on different products and different organizational conditions.     

Determining the scope and impact of market orientation profiles on strategy implementation and performance

Strategy implementation and performance in organizations are influenced by its market orientation. Market orientation is the collective of employee behaviors that affects strategy implementation, how an organization interacts with its environment and adjusts to changes within that context. The relationship between market orientation, strategy implementation, and performance is robust across environmental contexts. This study identifies ideal behavioral profiles for organizations seeking to maximize performance by considering the scope and impact of market orientation on strategy implementation. This is accomplished by considering market orientation and strategy profiles in relation to performance in a holistic coalignment perspective, corresponding to competitive contexts characterized by varying degrees of market turbulence and competitive intensity. Important strategic and performance implications of this dynamic are revealed that should be considered by academics and practitioners alike. Copyright © 2003 John Wiley & Sons, Ltd.

政府主导还是市场主导--我国转轨金融运行机制的评价研究

转轨过程中,我国金融运行机制是采取政府主导还是市场主导模式是经济学界争论的焦点,文章应用ARCH类模型对我国金融运行机制进行实证研究,结果表明我国金融运行机制与西方市场经济国家存在显著区别。在我国转轨的特定阶段,金融系统无法依靠自身的力量达到稳定状态,只有靠外部力量的非市场干预才能实现金融系统的平稳运行。目前在金融系统自身不具备自我稳定的功能条件下,政府的外部干预是金融系统平稳运行的前提,否则会导致金融系统陷入剧烈的波动之中。
