农产品供应链具有不同于工业供应链的独特性,链中的知识共享活动及影响因素也有区别。文章构建了我国农产品供应链这一特定情境下知识共享影响因素的理论模型,并利用问卷调查和结构方程模型方法开展实证分析。结果表明,农产品供应链的稳定性、信息化水平和文化氛围正向影响链中知识共享的效果,链的长度不仅显著负向影响链的稳定性,而且和节点间的知识距离对共享效果产生负向影响。基于这些结论,文章得出了提升我国农产品供应链知识共享效果的管理启示。 相似文献

以共享意愿和沟通两个因素为出发点,研究影响供应链知识共享效果的相关因素。通过分析影响共享意愿和沟通两因素的前置变量,构建出影响供应链知识共享效果的因素模型。以华东地区12家大型国有企业为研究样本进行的实证分析结果表明:供应链知识共享的意愿、沟通与知识共享效果显著正相关;供应链企业知识共享意愿与沟通显著正相关;沟通对知识共享意愿和知识共享效果之间起到部分中介作用。 相似文献

在文献研究及概念介绍基础上,文章运用斯坦伯格博弈模型对农产品供应链上下游企业间是否愿意共享资源进行研究,随后运用智猪博弈模型对谁来主动实施共享型农产品供应链进行决策分析。研究表明,通过共享资源,农产品供应链上下游企业可以获得更高的效益,实施共享型农产品供应链是双方的最优行为决策,而由大型企业带头实施共享型农产品供应链效果更佳,小型企业则等待配合大型企业实施即可。共享型农产品供应链的建设和实施可有效提高农产品供应链效率,应加强供应链上下游企业间有形资源及无形资源的共享程度。 相似文献

集群供应链是产业集群背景下新兴的供应链模式,对区域经济的发展具有重要意义。知识作为企业的核心生产资料,是影响供应链整体运作效率的重要因素之一。为了促进区域经济和地方产业的发展,对集群供应链知识共享行为进行了研究。本文运用演化博弈论建立了集群供应链中横向企业间知识共享行为演化博弈模型,分析了集群供应链知识共享行为的演化路径和影响知识共享行为的企业特质。研究结果表明：集群供应链知识共享行为主要受共享成本、共享风险、边际效益,知识吸收能力,知识共享量,激励系数和惩罚系数7个企业特质的影响;降低共享成本和风险,提高边际效益、知识吸收能力和知识共享量,引进激励和惩罚机制能够提升集群供应链中企业选择进行知识共享的意愿。 相似文献

为了提高供应链知识共享活动的效率,有效地平衡知识共享的深度和速度,运用Logistics增长模型对供应链知识共享过程建立数学模型,从知识属性的角度分析供应链知识提供方的知识外化活动与知识接受方的知识内化活动。研究发现,知识提供方的知识外化能力、知识初始状态的显性程度、知识接受方的知识内化能力、知识共享的环境、知识的价值与黏性等因素影响着供应链知识共享过程的效率。 相似文献

供应链中的知识交易与定价研究 总被引：9，自引：0，他引：9
随着知识经济的发展,供应链中的知识共享开始引起人们的关注。然而通过博弈模型分析发现,供应链中知识的无偿共享通常难以实现。而传统的交易费用经济学由于假设知识获取无成本也难以有效解决此问题。因此,在供应链中引入知识交易机制,详细分析供应链中知识供给者和需求者之间发生的交易行为,重点依据知识的不同分类从显性知识和隐性知识两个角度对定价模型进行研究,力图从交易机制的角度完善供应链中的知识市场框架,从而对供应链中的知识共享产生一定的推动作用。 相似文献

本文对供应链上的知识类型、供应链能力分别作了界定,并在此基础上建立了知识共享与供应链能力二者的关系模型,进而针对不同类型知识的共享与供应链两类能力构成要素之间的关系、供应链两类能力之间的关系等方面内容提出了相关理论假设,为此后的实证研究奠定了基础。 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

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

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

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

Long-standing conflict between domain name registrants and trademark holders prompted the Internet Corporation for Assigned Names and Numbers (ICANN) to create a global, mandatory arbitration procedure known as the Uniform Dispute Resolution Policy (UDRP). The UDRP has been used in 2166 cases involving 3938 domain names as of 1 November 2000. The policy gives the initiator of a complaint, generally a trademark holder, the right to choose which ICANN-accredited dispute resolution service provider (RSP) will handle the case. During the preparation of the UDRP,some feared that complainant selection would lead to "forum shopping" that might bias the results. This article performs a statistical assessment of the forum-shopping thesis and finds support for it. There are statistically significant differences in the various RSPs' propensity to take away names from defendants; there are also major differences in the number of cases brought to each RSP. RSPs who take away names have the larger share of cases. The study examines other variables that might explain differences in market share, such as price, the plaintiff's nationality, or the time taken to decide a case. It finds that nationality and time also are correlated with market share. The study concludes that shopping for a favorable outcome is an important factor in the UDRP. 相似文献

<正>In Xishuangbanna,one of China’s most biodiverse regions,landscape has changed dramatically during the past three decades due to the conversion of tropical rainforest to rubber plantations.In steep areas,terraces are often constructed before planting rubber trees,which causes two important changes in the soil:the destabilization of soil in the bench terraces and the increased vulnerability of unvegetated riser faces to erosion.Few studies have documented the nature and intensity of erosion on bench terraces.Prof.LIU Wenjie and his colleagues from the Xishuangbanna Tropical Botanical Garden(XTBG)conducted a study in Menglun County(21°5′39″N,101°15′55″E),Xishuangbanna to evaluate the influence 相似文献
