本文利用2004—2014年在深圳交易所创业板上市的148家新创企业数据,基于组织二元性理论,探讨新创企业的二元式创新行为,实证检验二元创新战略、产学研合作以及新创企业绩效之间的关系.结果显示： 未引入产学研合作变量时,二元创新战略对新创企业绩效没有显著影响;将产学研合作作为权变因素时,以上两者关系受产学研合作的调节效应显著,即在具有产学研合作的新创企业中,二元创新战略对其绩效具有显著正向影响;在没有产学研合作的新创企业中,二元创新战略对企业绩效没有显著影响. 相似文献

产学研合作是国家创新体系中的重要组成部分,在企业技术进步、高校科研发展、社会科技发展中发挥关键作用。本文探讨了产学研合作培养创新人才中的影响因素对合作培养创新人才效果的影响,以及合作培养过程的中介作用和创新环境的调节作用。选取环渤海地区的高校和高新企业的员工及其领导作为研究对象,通过发放调查问卷收集数据并进行实证分析。结果表明：产学研合作环境支持度、投入度和产出正向影响合作培养创新人才效果;产学研合作培养过程对合作培养影响因素与合作培养效果起部分中介作用;创新环境对二者的调节效应显著,即创新环境越优越,越利于提升合作培养创新人才的效果。 相似文献

因产品创新和工艺创新对知识、技术、技能的投入依赖度存在差异,创新组织方式对两类创新绩效存在不同的影响。以7499家有研发活动制造业企业为参照组,利用双对数回归模型估计江苏省4833家战略性新兴产业产品和工艺创新绩效及其影响因素。结果显示,政府研发补贴对参照组的产品和工艺创新具有显著的直接影响,对目标组的影响都不显著;进一步分析发现,政府对目标组单个企业补贴强度低,没有助其跨过最低"研发投资门槛"。产学研合作对目标组产品创新影响大于参照组,对工艺创新影响小于参照组。政府研发补贴与产学研合作的交叉项对目标组产品创新具有显著影响,对工艺创新的影响不显著。依据实证结论,从研发补贴方式和产学研合作模式选择角度对提高战略性新兴产业产品和工艺创新效率提出几点政策建议。 相似文献

产学研协同创新是充分发挥高校和科研院所知识累积优势、提升企业研发能力的重要途径.针对现有理论解释产学研协同创新机制有效性的不足,从效用理论视角系统剖析产学研协同创新机制有效性的影响因素,并在此基础上构建系统动力学模型.仿真结果表明:创新主体主客观效用差异越小,协同创新机制越有效;IT能力、地理位置邻近性对隐性知识供需匹配度具有显著正向影响,其中IT能力的影响更强,隐性知识供需匹配度对产学研协同创新机制有效性具有显著正向影响;创新主体间关系嵌入机制,即信任机制对产学研协同创新机制稳定性系统和协同创新机制的有效性具有显著正向影响,关系连带对隐性知识转移子系统和协同创新机制有效性具有显著正向影响;创新主体间文化相似性对产学研协同创新机制稳定性系统和协同创新机制的有效性具有显著正向影响. 相似文献

基于辽宁省企业经济信息库中企业技术能力的调研数据,利用倾向得分匹配方法控制参与产学研合作的内生性,对是否参与产学研合作、产学研合作研发强度对企业创新的影响及其作用机制进行实证分析.研究发现,参与产学研合作将显著提升企业的创新绩效,若忽略内生性影响将低估参与产学研合作的作用效果;产学研合作研发强度与企业创新绩效间呈U形关系;此外,产学研合作主要通过提升研发投入的使用效率来促进企业创新,但其不能显著提高人力资本投入的效率,即参与产学研合作会显著提高企业研发投入对创新产出的边际贡献率. 相似文献

基于伙伴选择视角,探讨伙伴选择对产学研协同创新的影响及其作用机制。通过对85个产学研协同创新项目的问卷调研,共获得68份来自项目主管、328份来自其他参与人员的有效配对样本数据,采用Amos和SPSS的PROCESS插件进行统计分析。实证结果表明,伙伴选择对产学研协同创新项目绩效有显著正向影响;合作关系在伙伴选择和产学研协同创新项目绩效之间起中介作用;利益分配显著正向调节合作关系在伙伴选择与产学研协同创新项目绩效之间的中介作用,即在高质量利益分配方式下,伙伴选择通过合作关系影响产学研协同创新项目绩效的中介作用显著,在低质量利益分配方式下,该中介作用不显著。 相似文献

以生物技术领域为例,在运用平均技术共现率（MTCR）和平均技术共类指数（MTCI）对生物技术领域专利技术进行共性特征的分析基础上,引入倾向得分匹配方法,对相同基本特征下的产学研合作专利、企业-企业合作专利、企业单独申请专利的技术共性特征进行了比较研究,实证检验了产学研合作对生物技术领域产业共性技术创新的影响效用。结果表明,产学研合作对生物技术领域共性技术研发创新有显著的正向影响,同时不同技术领域以及不同国别的产学研合作创新效应存在显著差异。在发挥产学研合作积极作用的同时,应考虑不同技术领域特点和区域政策的情景差异,从而实现产业共性技术突破,提升产业竞争力。 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

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

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
