高等教育国际化绩效与教育质量和人才水平紧密相关,其中商科教育始终位列各类国际化专业之首,因此从此学科切入研究教育国际化问题具有一定的代表性。本文沿用以国际间的双向沟通与交流为核心的商学教育国际化定义,结合商学的学科特点,通过完善和调整已有的高等教育国际化指标体系,构建了包含7项定性指标和15项定量指标的商学教育国际化绩效评价指标体系。本文以32家国内商学院和16家国外商学院为研究样本,通过问卷调查和实地调研收集数据,并采用投入归一化的DEA模型分别从战略、教学、科研、管理和人员5个维度对国内外商学院的教育国际化绩效进行评价和比较。由于教学维度的两项指标存在统计困难,实际收集到的是区间数据,因此在此维度的绩效测度中采用了分别计算绩效得分下界和上界的两组DEA模型。基于绩效测度结果,本文发现：国内商学院和国外商学院在管理和人员两个方面的国际化绩效差别不大,相比于国外商学院,国内商学院在科研方面的国际化绩效较好,但在战略和教学两个方面的国际化绩效较弱,并且在教学国际化程度上具有明显的劣势。鉴于国内商学院在各维度下表现出的绩效损失,本文对其提出如下改进国际化绩效的建议：战略方面,依托地区教育资源及发展优势,积极与境外商学院展开合作;教学方面,深入推进课程的国际化,鼓励外文授课和使用原版教材,大力拓展中外合作办学项目;管理方面,将国际化纳入提拔干部和评聘职称的考量因素,扩大学院自身的书刊资源库,营造良好的国际化氛围;人员方面,引入国际化师资力量,适当提高外教在教师队伍中的占比。 相似文献

This study investigates how business research scholars’ internationalization strategies influence their research performance and how this relationship is moderated by the availability of different knowledge-based resources. The authors analyze citations to journal articles authored by business research scholars with German affiliations and examine how the number of citations is determined by international collaborations and a researcher's knowledge resources in terms of language skills, research experience, and foreign market knowledge. The results demonstrate that the augmentation of complementary knowledge resources (i.e., when researchers lack language skills and foreign market knowledge) positively influences the performance of a collaboration-based internationalization strategy (i.e., collaborations with international researchers). The collaboration-based strategy also improves performance for less experienced researchers, but this advantage diminishes with increasing research experience. The findings provide further insights into drivers of scholars’ research performance and have practical implications for science policy. 相似文献

This paper considers the use of the h-index as a measure of a journal’s research quality and contribution. We study a sample of 455 journals in business and management all of which are included in the ISI Web of Science (WoS) and the Association of Business School’s peer review journal ranking list. The h-index is compared with both the traditional impact factors, and with the peer review judgements. We also consider two sources of citation data – the WoS itself and Google Scholar. The conclusions are that the h-index is preferable to the impact factor for a variety of reasons, especially the selective coverage of the impact factor and the fact that it disadvantages journals that publish many papers. Google Scholar is also preferred to WoS as a data source. However, the paper notes that it is not sufficient to use any single metric to properly evaluate research achievements. 相似文献

How do the effects of cognitive openness and structural openness on the research impact of business scholars vary over their careers? By analysing a longitudinal sample of 35,296 scholars who published in business and management journals, we show that the cognitive openness and the structural openness of business scholars have non-linear relationships with their research impact. In particular, we found that, whereas moderate levels of cognitive openness and structural openness are desirable for increasing young scholars’ citations, a high level of cognitive openness and a low level of structural openness contribute to senior scholars’ citations. This study contributes to our understanding of different search behaviour across business scholars’ career paths and its implications for scholars’ research impact. 相似文献

In 2019, the International Journal of Information Management (IJIM) celebrated its 40th year of publication. This study commemorates this event by presenting a retrospect of the journal. Using a range of bibliometric tools, we find that the journal has grown impressively in terms of publication and citation. The contributions come from all over the world, but the majority are from Europe and the United States. The journal has mostly published empirical articles, with its authors dominantly using quantitative methodology. Further, the culture of collaboration has increased among authors over the years. The journal publishes on a number of including managing information systems, information technologies and their application in business, technology acceptance among consumers, using information systems for decision making, social perspectives on knowledge management, and information research from the social science perspective. Regression analysis reveals that article attributes such as article order, methodology, presence of authors from Europe, number of references, number of keywords, and abstract length have a significant association with the citations. Finally, we find that conceptual and review articles have a positive association with citations. 相似文献

Criticism is mounting on business schools for their excessive focus on research and the relative neglect of teaching quality. This paper shows that if students have imperfect information about teaching quality and if business schools differ in their research productivity, the least productive schools would do as much research as the top-tier ones only to manipulate students’ expectations. In turn, the most productive schools might resort to excess research in order to signal their type in the eyes of prospective students. Since resources are limited, they also tend to neglect teaching quality. Such a situation is socially inefficient as compared to the perfect information case. 相似文献

As university involvement in technology transfer and entrepreneurship has increased, concerns over the patenting and licensing of scientific discoveries have grown. This paper examines the effect that the licensing of academic patents has on journal citations to academic publications covering the same scientific research. We analyze data on invention disclosures, patents, and licenses from the University of California, a leading U.S. academic patenter and licensor, between 1997 and 2007. We also develop a novel “inventor-based” maximum-likelihood matching technique to automate and generalize Murray's (2002) “patent-paper pairs” methodology. We use this methodology to identify the scientific publications associated with University of California patents and licenses.Based on a “difference-in-differences” analysis, we find that within our sample of patented academic discoveries, citations to licensed patent-linked publications are higher in the three years after the license, although this difference is not statistically significant. We then disaggregate our sample into (a) patented discoveries that are likely to be used as “research tools” by other researchers (based on the presence of material transfer agreements (MTAs) that cover them) and (b) patented discoveries not covered by MTAs. Citations to publications linked to licensed patents in the latter subset (not covered by MTAs) are higher for publications linked to licensed patents, and this difference is statistically significant. In contrast, licensing of patented discoveries that are also research tools is associated with a reduction in citations to papers linked to these research advances, raising the possibility that licensing may restrict the flow of inputs to “follow-on” scientific research. 相似文献

There is a considerable volume of prior research on the relationship between innovation and patents. Those research studies reveal that patents contain a great deal of noise, and unless a correction is made in terms of the value of individual patents, a simple count of the number of patents does not constitute a very useful indicator. From research that has been conducted for the purpose of finding such an indicator to show the value of individual patents (that is, research to identify the characteristics of valuable patents), many kinds of value indicators have been proposed. Nevertheless, research hitherto has focused primarily on business or private value derived from the possession of patents, and little attention has been paid to value in terms of technical knowledge or social value. In a survey of inventors conducted by RIETI in 2007, terminology describing broad concepts was used when questioning inventors about the value of individual patents, and this has provided an excellent opportunity to analyze the multiple factors lying behind the value of patents and how they impact one another.The purpose of this research is to use data from the RIETI survey of inventors and structural equation modeling methods to elucidate the relationships between the technological and business value of patents, and the latent factors that influence them. The findings show that a scientific-technological motive for inventors would have a positive effect on both the business and technological value, meanwhile, the monetary or promotion motive would not have any direct effects on the value of a patent. The model also suggests that academic linkage would have a strong positive effect on the technological value but a weak negative effect on the business value. Furthermore, these relationships differ more markedly according to technological field. 相似文献

This paper applies network analysis to a citation database that combines the key references in the fields of Entrepreneurship (ENT), Innovation Studies (INN) and Science and Technology Studies (STS). We find that citations between the three fields are relatively scarce, as compared to citations within the fields. As a result of this tendency, a cluster analysis of the publications in the database yields a partition that is largely the same as the a priori division into the three fields. We take this as evidence that the three fields, although they share research topics and themes, have developed largely on their own and in relative isolation from one another. We also apply a so-called ‘main path’ analysis aimed at outlining the main research trajectories in the field. Here we find important differences between the fields. In STS, we find a cumulative trajectory that develops in a more or less linear fashion over time. In INN, we find a major shift of attention in the main trajectory, from macroeconomic issues to business-oriented research. ENT develops relatively late, and shows a trajectory that is still in its infancy. 相似文献

Systematic evaluations of publicly funded research sometimes use bibliometrics alone or bibliometric-informed peer review, but it is not known whether bibliometrics introduce biases when supporting or replacing peer review. This article assesses this by comparing three alternative mechanisms for scoring 73,612 UK Research Excellence Framework (REF) journal articles from all 34 field-based Units of Assessment (UoAs) 2014–17: REF peer review scores, field normalised citations, and journal average field normalised citation impact. The results suggest that in almost all academic fields, bibliometric scoring can disadvantage departments publishing high quality research, as judged by peer review, with the main exception of article citation rates in chemistry. Thus, introducing journal or article level citation information into peer review exercises may have a regression to the mean effect. Bibliometric scoring slightly advantaged women compared to men, but this varied between UoAs and was most evident in the physical sciences, engineering, and social sciences. In contrast, interdisciplinary research gained from bibliometric scoring in about half of the UoAs, but relatively substantially in two. In conclusion, out of the three potential sources of bibliometric bias examined, the most serious seems to be the tendency for bibliometric scores to work against high quality departments, assuming that the peer review scores are correct. This is almost a paradox: although high quality departments tend to get the highest bibliometric scores, bibliometrics conceal the full extent of departmental quality advantages, as judged by peer review. This should be considered when using bibliometrics or bibliometric informed peer review. 相似文献
