Highly skilled return migrants contribute to the establishment of ties between the home and host systems. This paper studies how the professional ties, which Argentinean researchers built up during the time spent in foreign research systems, influence their collaboration patterns and their research outputs upon return. It confirms the expectation that having foreign work experience helps to explain the propensity to co-publish internationally and it also shows that researchers collaborate to a higher degree with their former host system. Another central finding is that foreign work experience has a positive effect on the propensity to publish in journals with a high impact factor. Additionally, a large share of this type of research is published without international co-authorship. We therefore do no not find evidence of a lack of publication autonomy in the case of Argentinean returnees.  相似文献

基础研究的经济回报率测度与评价:国外研究述评   总被引:6,自引:0,他引:6  
葛朝阳  郑刚  陈劲 《科研管理》2003,24(1):44-50
随着基础研究活动规模和投入经费的不断扩大,对其投入的经济回报进行测度与评价的要求越来越迫切。几十年来,国外许多学者对此进行了有益的探索。现有的大多数有关基础研究回报率的估计与测度都或多或少基于科学研究与创新(商业化)间的线性作用模型,没有充分考虑到其复杂性、非线性和知识外溢效应等,存在方法论上的缺陷,此外测度方法与手段也需进一步创新。  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

本文以中科院所属研究院所科研人员为主要调查对象,从跨界合作网络的视角出发,分析专利产出性别差异的社会网络机制。研究主要有3个发现:1.女性科研人员跨界合作网络规模和网络关系强度上均存在明显的欠缺;2.与企业界、其他学科领域合作网络规模和网络关系强度上的欠缺是影响专利产出性别差异的重要因素,而且网络关系强度的影响作用要大于网络规模的影响;3.性别对于跨界合作网络与专利产出关系的调节作用并不显著,即在拥有相同网络规模和网络关系强度的情况下,女性从与各类合作网络关系中获得专利产出回报的可能性与男性并无显著区别。与男性同事相比,女性的专利产出会更多地受到其他因素的影响,如职业早期的企业工作经历、单位组织的知识产权培训等。最后,在结果讨论的基础上提出在学术成果商业化新趋势下减少科技领域性别差异的政策建议。  相似文献

This paper uses a unique data set of Mexican researchers to explore the determinants of research output and impact. Our findings confirm a quadratic relationship between age and the number of published papers. However, publishing peaks when researchers are approximately 53 years old, 5 or 10 years later than what prior studies have shown. Overall, the results suggest that age does not have a substantial influence on research output and impact. We also find that reputation matters for the number of citations but not publications. Results also show important heterogeneity across areas of knowledge. Interpretations of other aspects, such as gender, country of PhD, and cohort effect, among others, are also discussed.  相似文献

Through an analysis of 497 foreign researchers in Italy and Portugal we verify the impact of home linkages on return mobility choices and scientific productivity. We consider the presence of several different types of linkages of the researchers working abroad with their country of origin and control for the most relevant contextual factors (age, research area, position in the host country, etc.). The probability of return to their home country and scientific productivity in the host country are both higher for researchers that maintain home linkages. We conclude that the presence of home linkages directly benefits both countries in addition to the indirect benefit of expanding the scientific networks. Policy implications and suggestions for further research are discussed.  相似文献

This paper examines the different channels through which academic researchers interact with industry and the factors that influence the researchers’ engagement in a variety of interactions. This study is based on a large scale survey of UK academic researchers. The results show that university researchers interact with industry using a wide variety of channels, and engage more frequently in the majority of the channels examined - such as consultancy & contract research, joint research, or training - as compared to patenting or spin-out activities. In explaining the variety and frequency of interactions, we find that individual characteristics of researchers have a stronger impact than the characteristics of their departments or universities. Finally, we argue that by paying greater attention to the broad range of knowledge transfer mechanisms (in addition to patenting and spin-outs), policy initiatives could contribute to building the researchers’ skills necessary to integrate the worlds of scientific research and application.  相似文献

The academic field of entrepreneurship research has grown from groups of isolated scholars doing research on small businesses to an international community of departments, institutes, and foundations promoting research on new and high-growth firms. Growth has produced increasingly systematic and interconnected knowledge and growing numbers of knowledge producers and knowledge users share core concepts, principles, and research methods, and a handful of highly cited scholars have emerged as thought leaders within research subfields. The field is increasingly formalized and anchored in a small set of intellectual bases, although there are also some signs of differentiation and fragmentation. Using an institutional theory perspective and drawing upon my experience in the field, I explore six forces creating the institutional infrastructure. First, social networking mechanisms have created a social structure facilitating connections between researchers. Second, publication opportunities have increased dramatically. Third, training and mentoring has moved to a collective rather than individual apprenticeship model. Fourth, major foundations and many other smaller funding sources have changed the scale and scope of entrepreneurship research. Fifth, new mechanisms have emerged that recognize and reward individual scholarship, reinforcing the identity of entrepreneurship research as a field and attracting new scholars into it. Sixth, globalizing forces have affected all of these trends. I conclude with some thoughts about the consequences of these developments with regard to the giving of practical and timely advice to entrepreneurs, the effects of American hegemony on choices of research topics and methods, and the possible loss of theoretical eclecticism.  相似文献

随着学术研究的日益规范化和复杂化,合作成为增加科研产出的主要途径。本文通过问卷收集了主要院校的科研评价制度,将其与三大经济管理类期刊的论文发表数据进行匹配,基于2000-2014年间部分高校调整第一作者制度的准自然实验,采用双重差分法(DID)的设计考察了科研制度对论文合作的影响。研究发现:(1)评职称认可非第一作者的制度能够使得论文合作的概率显著提高约33.5%,而评奖励承认非第一作者的制度没有显著影响;(2)在考虑了合作的异质性后,非第一作者制度主要促进了跨校合作,对院内合作和同校跨院合作的影响不明显;(3)作用机制分析表明,这种合作效应主要源自教师面临的晋升压力。本文的结论对于推动科研评价体系改革具有重要参考价值。  相似文献

This paper analyses the role of national research funds in promoting scientific production in emerging economies. The study focuses on the impact of the Chilean National Science and Technology Research Fund (FONDECYT). The analysis uses data drawn from international sources of bibliometric information combined with the administrative records of the program's executing unit. To measure the program's impact, we implement a regression discontinuity (RD) design on principal researchers who applied for funding between 1988 and 1997 considering as outcomes both quantity (publications up to 2002) and quality (citations up to 2005) of their scientific production. Our results show significant and positive impact in terms of publications, but no impact in terms of quality of scientific production in the proximity of the program's threshold ranking.  相似文献
