经济全球化中的"价值链"和"经济租"初探

"全球价值链"的表现形式之一是今天称霸全球的跨国公司,它的快速生长是最近全球化进程中最突出的现象;由于它正在覆盖全球市场,正在改变经济生活中的支配关系和利益分配,由于"全球价值链"治理的目标是追求"经济租",而且"经济租"由于"全球价值链"的大扩展而超越了"要素回报"的经济学意义,改变了经济中的分配格局,因此"价值链"不再是一个商业战略和管理问题,而是一个经济学问题;"市场"的概念也应当随经济的全球化而重新定义。目前中国和其他发展中国家面临的全球化挑战,就是在"全球价值链"的笼罩下谋求生存和发展。

Impact of outsourcing on business-to-business marketing: An agenda for inquiry

Increasing globalization has made companies focus more on their outsourcing decisions. Moving beyond the tactical companies have begun to incorporate outsourcing as a strategic weapon in their armory. This article expands on this theme by highlighting the need for understanding this key issue from business marketing and sales perspective and pointing to some interesting research issues on the topic. The article also introduces this special issue, briefly discusses the six special issue articles and provides a framework that integrates their contributions to our understanding of strategic outsourcing.     

Intraday Value at Risk (IVaR) using tick-by-tick data with application to the Toronto Stock Exchange

This paper investigates the use of tick-by-tick data for intraday market risk measurement. We propose a method to compute an Intraday Value at Risk based on irregularly spaced high-frequency data and an intraday Monte Carlo simulation. A log-ACD–ARMA–EGARCH model is used to specify the joint density of the marked point process of durations and high-frequency returns. We apply our methodology to transaction data for three stocks actively traded on the Toronto Stock Exchange. Compared to traditional techniques applied to intraday data, our methodology has two main advantages. First, our risk measure has a higher informational content as it takes into account all observations. On the total risk measure, our method allows for distinguishing the effect of random trade durations from the effect of random returns, and for analyzing the interaction between these factors. Thus, we find that the information contained in the time between transactions is relevant to risk analysis, which is consistent with predictions from asymmetric-information models in the market microstructure literature. Second, once the model has been estimated, the IVaR can be computed by any trader for any time horizon based on the same information and with no need of sampling the data and estimating the model again when the horizon changes. Backtesting results show that our approach constitutes reliable means of measuring intraday risk for traders who are very active in the market.     

保险产业集聚效应及其竞争力探源

产业集聚反映着保险业市场主体的价值链上下游整合与空间布局关系。由于保险业产业自身特性及国际金融以混业经营为其主流，国际上很少形成单一的保险业集群，保险业集聚寓于金融集聚之中；又由于传统保险业的技术专用性较低，故而保险业产业价值链比较简单，保险业的地域集中具有优于保险业前后向整合，打通产业链的竞争优势。保险业集聚有利于产品业务创新，业务外包和保险产业资产结构轻型化，可从根本上提升整体产业的竞争力。     

INTERORGANIZATIONAL TIME‐BASED POSTPONEMENT IN THE SUPPLY CHAIN

This paper presents the results of empirical research on the use of time‐based postponement in a supply chain context using data collected from two manufacturers, a distributor, and a retailer. The analysis shows that implementing postponement at the firm level can result in the supply chain carrying more inventory. In order to achieve its full potential, postponement needs to be implemented across organizations in the supply chain.     

Grey Critical Chain project scheduling technique and its application

Based on the idea of Grey System and interval number coefficient notation, a Grey Critical Chain scheduling approach is studied. According to Grey system Theory, the time of project or task completion can be considered as the object that extension is definite but intension is uncertain, which is coincident with the character of the project management. The Grey Critical Chain Scheduling Technique mainly aims at the single project time management, but the management idea can also be applied to the other knowledge areas of the project management. In this technique, we improve the selection method of the buffer time in the Critical Chain, in order to obtain reasonable Feeding Buffer time and Project Buffer time. In this paper, we will use an example to discuss the Grey Critical Chain Scheduling Technique, compare Grey Critical Chain with Program Evaluation and Review Technique, Critical Chain and Fuzzy Critical Chain, and analyze the advantages, disadvantages and applicable scope of their own.     

The value relevance and reliability of reported goodwill and identifiable intangible assets

We examine the value relevance and reliability of reported goodwill and identifiable intangible assets under Australian GAAP from 1994 to 2003; a period characterised by relatively restrictive accounting treatment for goodwill and relatively flexible accounting treatment for identifiable intangible assets. Our findings, using an adaptation of Feltham and Ohlson (1995), suggest that for the average Australian company the information presented with respect to both goodwill and identifiable intangible assets is value relevant but not reliable. In particular, goodwill tends to be reported conservatively while identifiable intangible assets are reported aggressively.     

客户化供应链下顾客生命周期价值计量研究

在客户化供应链中,顾客资产对企业的生存和发展发挥着至关重要的作用,而目前缺乏对顾客生命周期价值计量的有效探讨。为此,基于客户化供应链的研究背景,在综合现有研究顾客生命周期价值不同成果的基础上获得了顾客生命周期价值计量模型,并针对该模型的不足提出了修正方案,从而获得最终的顾客生命周期价值计量模型,为提高供应链企业顾客资产管理水平,促进供应链企业顾客资产的增值提供计量依据。
