作为技术创造和技术转移的社会实验,建立科技园区可能成功也可能失败。本研究利用国内8个科技园内457家高技术企业的问卷调查数据,对科技园的"温床效应"、"围城效应"以及高技术企业组织战略对创新效果的调节作用进行了考察和实证检验,研究发现:科技园的"温床效应"和"围城效应"并存,而且其对创新的主效应作用明显,但是高技术企业采取合理的组织战略可以促进"温床效应"对创新的正向作用,并且合理的组织战略可以负向调节科技园"围城效应"对企业创新的抑制性作用。基于研究结论,本文也为政府相关部门和入驻科技园的高技术企业提出具有针对性的政策建议。 相似文献

不同功能的科技园区为入驻企业提供的资源也是差异化的,研究把国内科技园区分为五类:综合功能型科技园,基础研究型科技园,技术研发型科技园,高技术产品加工区以及孵化器。利用量表设计和问卷调查方式,收集初级数据,建构方差分析和分组样本的探索性因子分析模型,讨论不同功能科技园提供资源的差异性。研究结果显示,不同功能的科技园区所供给的资源是显著差异的,这些资源差异性包括市场对接机会、人才集聚效应、产业集群的成熟度和功能、提供的研究资源以及竞争机制的差异性。从具体的科技园区功能分类来看,不同功能的科技园区所提供的资源既有共性也存在显著差异,研究中讨论了不同功能定位的科技园提供资源的重点不同,并根据研究结论提出相应的政策建议。 相似文献

根据文献回顾,建立相关研究假设和理论框架,提出了科技园区运行机制整合模型,探讨了科技园管理创新、企业入园的战略动机以及园内企业创新绩效之间的逻辑关系,认为科技园管理创新包括两个理论维度：一是科技园管理机构的相关政策;二是科技园管理机构的企业导入服务。企业入驻科技园的战略动机则分成两个维度进行讨论：一是企业入园的外在动机（利益性动机）;二是企业入园的内在动机（主观评估）。而园内企业的创新绩效则有技术研发、人才储备、市场开拓、研发资金等几个层面,本研究通过利用已有的成熟量表,测量相关潜变量,利用结构方程模型验证了假设并提出相关的政策性建议。 相似文献

为考察大学科技园是否能提升高科技中小企业的创新能力这一有争议的论题,对清华科技园中的中小企业进行了问卷调查,并和海淀区及北京市的高科技中小企业进行对比.研究发现,清华科技园的中小企业多是由一批年轻、高学历的企业家创办的以应用技术研发为主的高技术企业,有很强的创新意识.与其他中小企业相比,清华科技园的企业更善于利用科研机构的信息,研发层次更高,融资渠道更多,创新活动更活跃. 相似文献

分析企业入驻科技园的目的和动机对于大学科技园管理实践提供了重要理论与实证支持。采用能发挥专家隐性知识的DEMATEL方法进行分析,建立了大学科技园企业入驻动机的指标体系,从影响度、被影响度、中心度和原因度4个方面,分析了各动机在大学科技园企业入驻行为中的地位和作用,研究结果表明,功能不同和地理分布差异的大学科技园区为入驻企业提供的区域政策、资源禀赋、招商服务是有差异的。其中拥有核心技术、优惠的金融税收政策,丰富的市场资源是企业入驻的主要动机,并进一步为大学科技园的招商引资工作提出了政策性建议。 相似文献

以高技术企业为研究对象,讨论处于不同年龄阶段,针对不同成长速度下,高技术企业创新投入对企业成长的影响作用,对以往研究做出补充。研究发现:高技术企业研发投入对企业成长呈现倒U型关系;在高技术企业中,企业研发投入对于高成长速度的企业促进作用更强,且对于企业成长速度十分缓慢或衰退的企业,高技术企业研发投入并不能有效促进企业成长;对于高技术企业,企业年龄在企业创新对企业成长的影响关系中起到负向调节的作用,并且随着企业成长速度的加快,企业年龄在企业创新与企业成长关系中起到的负向调节作用越来越大。这意味着高技术企业需要适度的进行创新,同时应根据企业特征做出研发策略的调整。 相似文献

高技术企业具有知识密集、技术密集等特点,是促进我国经济与社会发展的重要部分,在国家发展中占据极其重要的地位。根据高技术企业技术创新的特点,在考虑时滞效应的基础上构建高技术企业技术创新的两阶段投入产出指标体系,应用动态两阶段DEA模型对两个阶段的绩效进行评价,通过对我国27个省域2012-2015年高技术企业技术创新绩效的评价,全面分析各省高技术企业在技术研发以及技术转化两个阶段的效率。研究表明：我国各省之间的高技术企业在技术创新水平上存在很大差距,而且大部分地区的高技术企业存在重视中间成果而忽略商品化产出的问题,需针对不同地区企业技术创新的差异性提出更具针对性的对策。研究成果为更客观的评价我国不同地区间高技术企业技术创新水平提供了工具,为不同地区制定相应的高技术企业技术创新政策提供了决策依据。 相似文献

在企业技术战略转型的过程中,研发资源的投入不断增加,因此如何有效地配置研发资源也成为重要的议题。从"战略-结构-绩效"范式的角度出发,以三一重工为例进行个案研究,对企业技术战略与研发资源配置结构、创新绩效的关系进行研究,结果表明研发资源配置结构会随着技术战略的变化而调整,并影响创新绩效。研究结果发展了"战略-结构-绩效"范式在技术管理领域的理论研究,为技术战略升级的资源优化配置提供理论依据。 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
