基于SDH的MSTP中的数据交换芯片设计

针对在SDH上构建多业务传输平台(MSTP)的需求,介绍了一种能在SDH传输和接入设备中提供灵活的数据业务支持的PoS(PacketoverSDH)数据交换芯片的设计方法。该芯片基于共享存储器的交换结构,采用了先进的流水线设计方式以提高整体交换容量。芯片支持服务质量保证(QoS)和组播(Multicast)功能,可用于SDH传输和接入设备中,为SDH上的数据业务支持提供简单而高效的解决方案。     

绿色食品的标识资产管理——理论框架与实证分析

绿色食品的标识资产是绿色营销中的一个新课题,借鉴品牌资产的概念,定义了绿色标识资产,并对绿色标识资产的关键驱动因素和对顾客忠诚的影响进行了系统的理论分析和实证研究。通过构建基于偏最小二乘法的结构方程模型发现,标识联想、标识感知质量和消费者介入程度对绿色标识资产起正向影响作用,进而对顾客忠诚产生显著、积极的影响。     

South African consumers' willingness to pay a premium for Karoo Lamb: The influence of subjective and objective knowledge,label information and demographics

In South Africa, Karoo Lamb is a prestigious product associated with free range production. This study examined the influence of subjective and objective Karoo Lamb knowledge, the importance of label information, and demographics on consumers' willingness to pay a premium for Karoo Lamb products. A panel of 355 consumers who had previously purchased lamb/mutton products completed an online questionnaire. The importance of Karoo Lamb label information, subjective Karoo Lamb knowledge and population group had a significant positive impact on willingness to pay a premium for Karoo Lamb. Objective Karoo Lamb knowledge and other demographics did not have a significant impact.

On the use of labels in credence goods markets

We analyze credence goods markets in the case of two firms. Consumers know that the quality of the good varies but do not know which firm is of high quality. First, we show that the high quality producer may be unable to monopolize the market, or even to survive in some cases, in situations where it is efficient and trusted by all consumers. Second, although a label restoring full information improves welfare, it may also reduce both firms’ profits by intensifying competition. Since even the high quality producer may not wish to label its product, in such cases the label must be mandatory. Third, an imperfect label which moves everybody’s beliefs closer to the truth without restoring full information may produce adverse results on market structure and welfare, either by increasing or by reducing the variance of beliefs.      

产品信息标签的技术诱导效应研究:基于能效标识制度的实证

运用关键词频统计法,构建中国1999-2013年节能节电专利面板数据,以能效标识制度为切入点,从专利数量、相对专利产出和技术重心等指标分析能效标识制度对技术创新的影响,进而考察产品信息标签对技术创新的诱导机制。研究发现:(1)能效等级信号是能效标识制度能否诱导技术创新的关键;(2)能效标识制度对节能节电类专利具有显著正向影响,即能效标识制度对技术创新具有显著诱导效应;(3)能效标识制度不仅能够提升节能节电专利与节水专利之间的比值,而且能够显著提高节能节电专利占所有专利的比例,即该政策导致偏向性技术进步;(4)相对而言,能效标识制度对创新程度较高的发明专利具有更强的诱导效应。为此,完善能效标识制度、推广产品信息标签,有助于引导技术进步,促进社会可持续发展。     

基于MPLS网络的LDP-VPLS组网方案

通过对多协议标签交换(MPLS)网络中实现虚拟专用局域网业务(VPLS)的关键性技术———虚电线和标签分布协议(LDP)的研究,发现基于此技术的VPLS全网格连接结构限制了VPLS的规模。本文在IETF层次化VPLS解决方案的基础上,设计出两个避免全网格问题的组网方案,利用连接不同级别的VPLS网络,减少虚电线的数量和提高网络的可扩展性。

Network agility as a trigger for enhancing firm performance: A case study of a high-tech firm implementing the mixed channel strategy

Original equipment manufacturers (OEMs) can reduce labor costs, free up capital investment and enhance firm's agility by full outsourcing of product manufacturing. OEMs can then focus on the most valuable processes, e.g. R&D and marketing. However, contract manufacturers (CMs) may decide to foster their own brand and forge their own relationships with retailers or distribution channels. The conflicts of interest between OEMs and CMs can be reduced by implementing a mixed channel strategy. Label licensing, the most essential component in the implementation, enhances the marketing capability of a CM and allows it to move up the value chain. In this research, a case study involving a supply chain network in the optical storage media industry is used to develop a conceptual model to explain how a mixed channel strategy and superior network agility enhance firm performance. This study argues that information system integration influences firm performance through network agility, and that the mixed channel strategy boosts financial performance. Moreover, the result proposes that network agility is associated with a moderating effect on the relationship between the mixed channel strategy and financial performance.
