管理学领域的创新是国际学者关注的热点之一。基于科学计量学、文献计量学基本原理,利用信息可视化技术,对2013年—2017年SSCI数据库中收录的3018条国际上管理学创新研究文献进行了可视化计量分析。研究结果显示：在研究热点方面,近5年来国际上管理学创新研究热点可以归纳为3个方面：一是关于创新自身研究,如“创新”“开放式创新”“技术创新”“创新绩效”和“创新模型”等；二是创新影响后果研究,如“企业绩效”“产品开发”“竞争优势”和“企业成长”等；三是创新前置因素研究,如“研发”“技术”“知识”“吸收能力”和“动态能力”等；同时,对国际上管理学创新研究热点演进情况进行了探索。在研究前沿方面,国际范围内管理学创新研究前沿主要聚焦在“科学的”“出口业绩”“资源”“双元”和“公司规模”等方面,并对国际上管理学创新研究前沿演进情况进行了分析。该研究为国内外管理学创新领域理论和实践研究提供有益参考。 相似文献

以探求创业板公司的规模对其研发投入的影响为主线,同时考虑高管工资、股权集中度、公司税负、董事会规模、经济景气指数以及上期研发投入等因素对研发投入的影响程度.鉴于此,以2010-2014年77家创业板公司年报数据为样本,对面板数据进行回归,研究发现公司规模与研发投入呈现“U”关系,存在着三个门限值;高管工资与研发投入呈现倒“U”关系;股权集中度、两权分离程度、公司税负等均与研发投入负相关;董事会规模、公司总资产增长率、经济景气指数均研发投入正相关;公司研发投入具有持续性特征.从国家层面和公司层面分别提出激发创业板公司研发投入积极性的对策. 相似文献

以研究科学技术政策的国际权威期刊《Research Policy》（科研政策）于1974-2016年刊载的2855篇文献作为数据样本,运用科学知识图谱方法,获取国际科技政策研究成果的机构、国家、区域分布;通过高频主题词分析,确定国际科技政策研究的热点领域;通过检测词频变动趋势显著的主题词确定国际科技政策研究的前沿领域与发展趋势变化,分析科技政策国际研究的演变历程。研究表明,科技政策国际研究在过去42年间发生了明显的变化,主要体现为：研究范围由早期零星的“科技政策”相关探索发展到目前注重“科技政策学”的科学规范化研究,研究视角由国家层面的宏观研究向微观倾斜,研究热点由知识管理、国家创新系统等扩展到开放式创新、三螺旋创新、团队知识创造等多样化研究。同时发现,科技政策国际研究在早期主要受到纳尔逊（RR Nelson）国家创新系统理论和波特（ME Porter）国家竞争优势理论的影响,而当前主要受到开放式创新理论、三重螺旋创新理论的影响。本文的研究为更加全面地了解科技政策国际研究的发展脉络和演化进程,把握该领域的知识基础、研究热点与发展方向提供了新的参考及依据。 相似文献

以工业增加值增长率的已实现波动率、已实现波动率的正半方差和负半方差分别度量经济不确定性、“好”的经济不确定性和“坏”的经济不确定性,选取2009—2019年中国1126家上市公司年度数据实证考察“好”“坏”不确定性对企业研发投入强度的影响及异质性影响机制。研究发现：经济不确定性对企业研发投入起到了促进作用,“好”的经济不确定性对企业研发投入具有显著的抑制效应,“坏”的经济不确定性对企业研发投入具有促进效应;这种效应对国有企业、高新技术企业和第二产业的企业的作用更为明显。在当前中国宏观经济下行压力加大背景下,该研究结论对国家实施创新驱动发展战略具有非常重要的政策启示。 相似文献

根据2013—2017年制造业上市公司数据，本文在手工收集企业实施“互联网+”指标的基础上，实证检验了“互联网+”战略对企业研发投入的影响及其对不同企业的异质性作用。结果表明，“互联网+”战略对企业研发投入具有显著促进作用；这种促进作用只在东部地区显著，而在中、西部地区不显著；“互联网+”战略更能促进国有和民营企业进行研发投入，对外资企业研发投入存在抑制作用；生产率影响了“互联网+”战略与企业研发投入的关系，生产率较高的企业实施“互联网+”战略的创新效应更强。扩展检验发现，“互联网+”战略对企业研发投入的促进作用具有持续性，并且其影响程度逐年增强。研究结论为进一步实施“互联网+”战略以及制造业创新发展提供了微观层面的经验证据及决策支持。 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

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
