在相关研究的基础上,将低碳创新作为中介变量,并将低碳创新划分为渐进式低碳创新、以技术为基础的突破式低碳创新和以市场为基础的突破式低碳创新,构建了绿色创业导向对组织绩效影响的概念模型,并以湖北省201家服务企业为样本对其进行了实证检验。研究发现,绿色创业导向对三种形式的低碳创新均有正向影响,三种形式的低碳创新均对组织短期绩效有正向影响,但渐进式低碳创新和以技术为基础的突破式低碳创新对组织长期绩效的正向影响不显著,唯有以市场为基础的突破式低碳创新对组织的长期绩效有显著正向影响。最后,根据研究结论,提出了相应的政策干预路径。 相似文献

战略导向对企业绩效具有重要的影响,但研究结论尚未达成一致,且对其具体作用机制现有文献还缺乏深入剖析。基于国内外相关文献的梳理,探索性地提出以创新模式为中介变量的战略导向对企业绩效影响机制的概念模型,并通过179家企业的实证研究发现:(1)市场导向和创业导向均能对企业绩效产生积极影响;(2)探索性创新与利用性创新均对企业绩效有正向影响,但同时追求两者反而会产生负向影响。(3)利用性创新在创业导向与企业绩效之间起到中介作用,而市场导向对企业绩效的影响将同时通过探索性创新和利用性创新产生。(4)创业导向型企业相对更偏重根本性的探索性创新,强调创新成果的突破性;而市场导向型企业则更偏向于进行渐进式的利用性创新。 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

在文献综述的基础上将低碳营销创新划分为渐进式低碳营销创新、以技术为基础的变革型低碳营销创新、以市场为基础的变革型低碳营销创新三种低碳营销创新方式,并将服务/市场配适、服务传递品质和营销沟通效果作为中间变量构建了低碳营销创新方式与营销绩效的关系理论模型,以国内261家服务业企业为样本,对模型进行实证检验。研究发现:渐进式低碳营销创新对营销绩效的直接正向影响不显著,但可以通过服务传递品质和营销沟通效果对营销绩效施加间接正向影响;以技术为基础的变革型低碳营销创新对营销绩效的直接正向影响不显著,但可以通过服务/市场配适、服务传递品质和营销沟通效果对营销绩效施加间接正向影响;以市场为基础的变革型低碳营销创新对营销绩效有显著的直接正向影响。 相似文献

本文将市场导向划分为市场驱动导向与驱动市场导向两种类型,以组织学习为中介变量,构建出市场导向对企业绩效影响的概念模型,并以湖南省高新技术开发区的企业为样本对其进行实证检验。研究发现:市场驱动导向对应用性学习有正向影响,对探索性学习有负向影响;驱动市场导向则只对探索性学习有正向影响;应用性学习和探索性学习都对企业绩效有正向影响。研究结论为高新技术企业如何实施市场导向提供了重要的管理启示。 相似文献

理论探讨并实证检验了企业正式制度资本与非正式制度资本对于突破式创新的影响机理及作用差异,并探究了技术能力和探索性市场学习对以上路径的中介作用机制。利用结构方程模型对303家企业的配套调研数据分析发现:首先,企业正式制度资本与非正式制度资本对突破式创新均呈现出正向促进作用,而后者的作用效果显著更强;其次,正式制度资本对突破式创新的作用效果被技术能力和探索性市场学习完全中介,而正式制度资本对探索性市场学习的正向促进作用大于其对技术能力的正向促进作用;最后,非正式制度资本对突破式创新的作用被技术能力和探索性市场学习部分中介,而非正式制度资本对技术能力的正向促进作用大于其对探索性市场学习的促进作用。 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

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

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

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
