本文从我国企业集团存在的“大而全”、“小而全”等典型问题出发,认为正确理解企业集团边界有助于解决这些问题,进而总结了不同类型企业集团边界决策的支撑理论。在此基础上重点研究了混合型企业集团有效边界的本质,认为企业集团的有效边界是动态的,在进行边界决策时要同时考虑静态环境下和动态环境下的成本节约。  相似文献

长期以来,厂商与用户之间存在的成本鸿沟被认为难以跨越,然而,随着云制造等新制造模式的兴起,构建跨组织成本协同机制成为厂商与用户的合作主导关系面临的关键问题。从产品制造为核心的商业模式刚性、竞争为主导的企业边界、产权鸿沟下市场机制的局限、决策代理人利己选择等多维度,对传统制造环境下的厂商成本与用户成本鸿沟形成机理进行解析,提出以价值生态系统为内核、推进产品与服务一体化、构建动态契约合作机制以及"连接红利"的跨界成本协同平台为路径的厂商成本、用户成本协同模型,为云制造环境下跨组织的成本优化提供理论框架,并通过案例分析对理论框架进行验证。  相似文献

企业家的决策模式有改良式决策与探索式决策两种模式。改良式决策是在企业的技术、组织结构以及管理模式等方面现有的基础上进行改良,有利于企业家更好地发挥这些因素在企业经营中的作用,但容易陷入次优稳定均衡;探索式决策模式是对现有的技术、组织结构以及管理模式等方面进行革新,以期提高企业的产出水平,但探索式决策所带来的不确定性比较大。对动态环境下具有战略眼光的企业家如何动态地组合这两种决策模式进行了理论分析,研究表明探索式决策在动态环境下是一种常态。  相似文献

闭环供应链中往往会产生正反两方向的"双重边际化效应",造成供应链系统效率的损失。研究了一个由制造商、零售商和第三方回收商组成的三级闭环供应链系统在模糊需求环境下的协调机制,分析了三方在分散决策和集中决策两种情形下的决策过程,并给出收入共享契约机制下的决策模型。最后通过一个算例分析表明,模糊需求环境下,收入共享契约机制可以有效协调闭环供应链中各方利润,并使供应链系统的总利润达到集中决策时的水平。  相似文献

以检查频率和废旧品回收率作为政府和制造商的博弈策略,引入环境损失系数和激励系数改进得益函数。根据决策的先后顺序,建立同步决策的博弈机制、政府决策在先的博弈机制、制造商决策在先的博弈机制,研究了不同环境损失系数和激励系数下,三种博弈机制的稳定性以及可能引发的社会问题。研究表明:政府公信力和企业诚信是博弈机制正常运行的前提条件;在决策自由度得到保证的前提下,政府应当依据环境损失系数,调整激励系数,实现"双赢"。  相似文献

Aresearch group led by Prof. ZHAI Qiwei from the Institute for Nutritional Sciences under the CAS Shanghai Institutes for Biological Sciences has discovered that even relatively low doses of resveratrol--a chemical found in the skins of red grapes and in red wine--can improve the sensitivity of mice to the hormone insulin, according to a report in the October,2007 issue of Cell Metabolism. As insulin resistance is often characterized as the most critical factor contributing to the development of Type 2 diabetes, the findings“provide a potential new therapeutic approach for preventing or treating” both conditions, the researchers said.  相似文献

This study examined how students who had no prior experience with videoconferencing would react to the use of videoconferencing as an instructional medium. Students enrolled in seven different courses completed a questionnaire at the beginning of the semester and again at the end of the semester. Students at the origination and remote sites did not differ in their reactions toward videoconferencing but there was a significant difference for gender. Women reacted less favorably to videoconferencing. Compared to the beginning of the semester, students reported significantly less positive attitudes toward taking a course through videoconferencing at the end of the semester. There were no significant differences in students' attitudes toward videoconferencing across courses at the beginning of the semester but there were significant differences across the courses at the end of the semester. The results suggest the need for better preparation for both students and instructors.  相似文献

Ajoint study by Prof. ZHANG Zhibin from the CAS Institute of Zoology and his co-workers from Norway, US and Swiss have indicated that historical outbreaks of migratory locusts in China were associated with cold spells, suggesting that China's projected climate warming could decrease the pest's numbers. The study was published in Proceedings of theNational Academy of Sciences on 17 September, 2007.  相似文献

CAS should stick to the principle of rendering service to, and giving impetus for, the development of China's science enterprise by making S&T innovations, said CAS President LU Yongxiang. The CAS president made the remarks in a recent talk to communicate the gist of the winter session of the Party's Leading-member Group at CAS, which was held from 7 to 11 January in Beijing.  相似文献

A computer-mediated group is a complex entity whose members exchange many types of information via multiple means of communication in pursuit of goals specific to their environment. Over time, they coordinate technical features of media with locally enacted use to achieve a viable working arrangement. To explore this complex interaction, a case study is presented of the social networks of interactions and media use among members of a class of computer-supported distance learners. Results show how group structures associated with project teams dominated who communicated with whom, about what, and via which media over the term, and how media came to occupy their own communication niches: Webboard for diffuse class-wide communication; Internet Relay Chat more to named others but still for general communication across the class; and e-mail primarily for intrateam communication. Face-to-face interaction, occurring only during a short on-campus session, appears to have had a catalytic effect on social and emotional exchanges. Results suggest the need to structure exchanges to balance class-wide sharing of ideas with subgroup interactions that facilitate project completion, and to provide media that support these two modes of interaction.  相似文献

With great care, Dr. ZHOU Zhonghe takes out a package wrapped by cotton tissue from a drawer and says: "This is the gem of our collections: the fossil of a bird that lived 125 million years ago!" Then, pointing at a tiny mound, he explains: "Look, this is the claw and that is the head. It was in the egg shell and ready to hatch ... The species fell into a family of waterside inhabitants."  相似文献

Electronic data interchange (EDI) provides means for interorganizational communication, creates network externalities, requires an advanced information technology (IT) infrastructure, and relies on standards. In the diffusion of such innovations, institutional involvement is imperative. Such institutions contain governmental agencies, national and global standardization organizations, local government, and nonprofit private organizations like industry associations. The last type of organizations we call intermediating institutions. They intermediate or coordinate ("inscribe") the activities of a group of would-be adopters. Unfortunately, little is known of how these organizations shape the EDI diffusion trajectory. In this article we examine one specific type of intermediating organizations?industry associations?and how they advanced the EDI diffusion process in the grocery sectors of Hong Kong, Denmark and Finland. We identify six institutional measures, placed into a matrix formed by the mode of involvement (influence vs. regulation) and the type of diffusion force (supply push vs. demand pull), that can be mobilized to further the EDI diffusion. Industry associations were found to be active users of all these measures to varying degrees. Their role was critical especially in knowledge building, knowledge deployment, and standard setting. Furthermore, institutional involvement varied due to policy and cultural contingencies and power dependencies.  相似文献

This essay focuses on universal service and the Internet as means to support social and political participation. The emphasis on access to telecommunications systems in conventional approaches to universal service is contrasted with access to content. A model of the information environment is described that accounts for the roles of content and conduit, both of which are necessary conditions to achieve true access. A method is outlined for employing information indicators to observe or measure the information environment.  相似文献

The increasing prospects of digital piracy has prompted the perceived need by electronic publishers to adopt technical systems of protection, and governments to reform their copyright laws. This article is a preliminary study of the management of intellectual property by electronic publishers, defined as those involved in the production of online databases, and CD-ROMs. It focuses on three main issues: (1) how electronic publishers view the increasing threat of piracy; (2) the methods of protection employed to protect intellectual property in digital format; and (3) the importance of technological protection of intellectual property in electronic publications. The analysis is based on a sample of 23 UK electronic publishers. The interviews revealed an interesting assortment of protection methods and did not show that technological protection was a preferred way. Instead, the means of protection, in addition to copyright law, comprised niche markets, pricing, trust, bad publicity, and nontechnical and technical means.  相似文献
