科技型小微企业是国家和区域创新发展战略实施的重要基础。考虑到企业家在产学研合作中的主导作用,从社会资本理论视角出发,对广东顺德地区186家科技型小微企业进行调查分析,研究结果表明:(1)企业家社会资本有助于科技型小微企业获得产学合作的机会,并且有助于提升企业的专利产出;(2)产学研合作有助于提高企业专利产出,并且其在企业家社会资本与专利产出之间起着中介作用;(3)合作创新意愿正向调节企业家社会资本与产学研合作之间的关系,即在高合作创新意愿的条件下,企业家社会资本对产学研合作的影响效果更为显著。 相似文献

使用2007—2018年中国上市公司数据并与其专利申请信息相匹配,探讨产学研合作对企业市场绩效的影响效果及内在机理。研究发现：产学研合作显著抑制了以营业收入增长率和托宾Q值测度的市场绩效,即产学研合作同时抑制了企业在产品市场和资本市场的市场绩效,并且这一负面影响可以持续2～3年。其内在影响机理在于,尽管产学研合作可以提高企业的技术创新水平,但却无法有效提升企业技术的商业价值,加之以产学研合作所耗费的机会成本,造成了产学研合作对企业市场绩效的抑制效应。进一步对产学研合作模式加以考察后发现,产学研合作广度显著抑制了企业市场绩效,合作深度则对市场绩效具有“U”型影响,说明只有进行较为深度的产学研合作才可能真正促进企业市场绩效。本研究为市场经济体制下全面评价产学研合作效果及影响机理提供了有益启示。 相似文献

广西产学研合作的科技产出效率水平偏低,分析产学研产出的影响因素及如何配置创新资源是提高广西产学研合作创新效率的关键。通过以投入—产出为合作创新绩效评价指标,运用灰色关联模型分析产学研产出的影响因素,结果显示广西产学研合作创新产出绩效与科技机构数、RD经费内部支持关联较大,与RD人员、政府支出、企业支出关联较小,与GDP关联性最小;运用DEA模型分析产学研创新绩效效率,结果显示产学研创新绩效水平低下,创新资源配置不合理,投入冗余,产出不足。 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
