将探索性学习作为绿色创业导向和低碳突破性创新间关系的中介变量,将低碳突破性创新划分为以技术为基础和以市场为基础的两类低碳突破性创新,构建了理论模型,并以中东部6省市208家大公司为样本,对模型进行了实证检验。研究发现：绿色创业导向对以技术为基础的低碳突破性创新有显著的正向影响,但对以市场为基础的低碳突破性创新的正向影响不显著;探索性学习对以技术为基础的低碳突破性创新有显著的正向影响,但对以市场为基础的低碳突破性创新的正向影响不显著;探索性学习在绿色创业导向和以技术为基础的低碳突破性创新之间发挥完全中介作用。 相似文献

服务业绿色创业导向对绿色服务创新和经营绩效的影响研究 总被引：1，自引：0，他引：1
尽管西方学术界提出了绿色创业概念,但鲜有学者对绿色创业与组织经营绩效之间的关系进行实证研究,更没有探讨绿色创业对组织经营绩效的作用机理.本研究在相关研究基础上,以服务业为研究对象,将绿色服务创新作为中介变量,并将绿色服务创新划分为利用式绿色服务创新和探索式绿色服务创新,构建了绿色创业导向对组织经营绩效影响的概念模型,并以中东部212家服务企业为样本进行了实证检验.研究发现:绿色创新性对两种绿色服务创新均有正向显著影响;绿色超前行动性和绿色冒险性仅对探索式绿色服务创新有正向显著影响,对利用式绿色服务创新的正向影响不显著;探索式绿色服务创新和利用式绿色服务创新均对经营绩效有正向显著影响,但前者对经营绩效的影响远远大于后者.该结论进一步丰富了绿色创业理论. 相似文献

在相关研究的基础上,将营销创新作为中介变量,将环境作为调节变量,并将营销创新划分为渐进式营销创新和突破式营销创新,构建了公司创业导向对组织绩效影响的概念模型,并以中东部八省市242家企业为样本进行了实证检验.研究发现,公司创业导向对组织绩效有正向积极影响,突破式营销创新在其间发挥了完全的中介作用,且环境在其中起着调节作用,而渐进式营销创新却没有发挥中介作用.该结论进一步丰富了创业导向理论,为企业创业导向的实施提供了一种新思路.

学者们在研究市场研究活动执行品质对产品(或服务)创新的影响时出现了分歧,为了找出分歧的原因,本研究在文献综述的基础上尝试将渐进式服务创新划分为以技术为基础和以市场为基础的渐进式服务创新,将突破式服务创新也划分为以技术为基础和以市场为基础的突破式服务创新,并构建了市场研究活动执行品质对服务创新的作用模型.本研究以国内266家服务业企业为样本,对模型进行实证检验.研究发现:市场研究活动执行品质对以技术为基础的渐进式服务创新和以技术为基础的突破式服务创新有正向的显著影响,同时,知识整合机制在其间发挥着调节效应;而市场研究活动执行品质对以市场为基础的渐进式服务创新和以市场为基础的突破式服务创新的正向影响不显著.本研究为解决市场研究活动执行品质对服务创新影响研究的分歧提供了新的途径和有益的探索. 相似文献

本文从产业网络的角度探究了新创企业“嵌入式”双元创新追赶机理,构建了基于机会型与资源型创业导向中介作用的理论框架。研究结果显示：（1）产业网络技术型与商业型嵌入对新创企业的双元创新追赶均具有显著的正向影响,其中,商业型嵌入对渐进式追赶影响更大,而技术型嵌入对突破式追赶影响更大;（2）产业网络双重嵌入对机会型与资源型创业导向也均具有显著的正向影响,且对资源型创业导向的影响更大;（3）机会型创业导向显著促进企业突破式创新追赶,而资源型创业导向显著促进企业渐进式创新追赶,即机会型与资源型创业导向与双元创新追赶之间存在对应关系。本研究指出了中国转型背景下新创企业创新追赶的有效路径,对于推动国家创新驱动发展战略具有重要的研究价值。 相似文献

A research 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 in red wine-can improve the sensitivity of mice to the hormone insulin according to a report in the October issue of Cell Metabolism.…… 《中国科学院院刊(英文版)》2008,22(1):14-15
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

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

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

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

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
