企业资源状况影响新产品开发中决策逻辑的选择,进一步影响新产品开发绩效。基于245份有效样本,检验了网络资源与技术资源对效果逻辑与因果逻辑的不同作用机制,以及两种决策逻辑在企业资源与新产品开发绩效间的中介作用。结果发现：网络资源对效果逻辑的正向影响强于技术资源,技术资源对因果逻辑的正向影响强于网络资源。同时,效果逻辑在网络资源与新产品开发绩效间存在中介作用,而因果逻辑在技术资源与新产品开发绩效间存在中介作用。 相似文献

研究的逻辑起点决定了研究方向和内容。对现象学技术哲学来说,不同的逻辑起点意味着现象学技术哲学研究的不同路径。美国现代技术哲学家阿尔伯特.伯格曼以技术人工物作为研究的逻辑起点,分析现代技术所呈现的世界图景,最终形成装置范式技术哲学研究纲领,并以装置范式论闻名于技术哲学界。对这一纲领逻辑起点的研究,有助于从整体上把握装置范式论思想及其意义。 相似文献

本文基于认知视角,采用探索性单案例研究方法,深入考察和分析动态视角下中国复杂产品系统企业技术发展的主导逻辑。研究发现：复杂产品系统企业中存在一种一以贯之的“技术归因”逻辑,其内涵体现为外部驱动、任务定义、任务实现和任务保障四个方面;复杂产品系统企业的“技术归因”逻辑具有“任务导向”和“技术聚焦”的特点,使企业聚焦于技术获取和产品研发任务,从而获得长期绩效和持续竞争优势。文章进一步探讨了“技术归因”认知逻辑的惯性特征对自主技术创新的影响、不同组织阶层逻辑差异、与行业逻辑匹配性等问题,及其对中国复杂产品系统企业具有的管理启示。 相似文献

一直以来,关于我国“以市场换技术”制度的有效性研究一直存在较大的分歧。从制度逻辑的微观视角出发,通过三花与兰柯、丹佛斯两个企业竞合事件的纵向案例分析,研究发现：“以市场换技术”范式下中外企业竞合过程中的主导制度逻辑变革包括改革型逻辑转变和发展型逻辑转变两种范式。在改革型逻辑转变过程中,中国企业基于市场优先策略,采取先隔离再跟进的市场启发机制和先探索再利用的技术积累范式。而在发展型逻辑转变过程中,中国企业则基于技术优先策略,采取的是先跟进再隔离的市场启发机制和先利用再探索的技术积累范式。研究结论对于我国企业如何充分利用市场规则和技术机制来实现竞争赶超具有实践启发意义。 相似文献

本文主要探讨了技术逻辑导向对新创企业创新行为的作用机制以及在技术逻辑导向下新创企业创新行为对创新绩效的影响。基于新创企业的发展阶段,实证研究了技术逻辑导向、创新行为与创新绩效之间的关系。研究发现：技术逻辑导向下新创企业技术创新行为与组织制度创新行为在不同的发展阶段耦合形式不同;在创建阶段,新创企业会仅采取技术创新行为;在生存阶段,新创企业会同时采取技术创新行为与组织制度创新行为,但会以组织制度创新为主而技术创新为辅;在成长阶段,新创企业也会同时采取两种创新行为,但此时会以技术创新为主而以组织制度创新为辅;采取技术逻辑导向战略在一定程度上会提升新创企业的创新绩效。 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
