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

This study analyses the changing effect of physical distance and territorial borders (regional, national, language) on the intensity of research collaboration across European regions. Using data on all co-publications between 313 regions in 33 European countries for the period 2000-2007, we find that the bias to collaborate with physically proximate partners did not decrease, while the bias towards collaboration within territorial borders did decrease over time. Our results show that the ongoing process of European integration is removing territorial borders, but does not render collaboration less sensitive to physical distance. Given this general trend, there is considerable heterogeneity between regions and countries in their propensity to collaborate which we attribute to differences in size, quality and accessibility. The findings and conclusions are framed within the context of European research policies.  相似文献

This paper analyzes the effect of university research centers on the productivity and collaboration patterns of university faculty. University research centers are an important subject for policy analysis insofar that they have become the predominant policy response to scientific and technical demands that have not been met by extant institutions, including academic departments, private firms, and government laboratories. Specifically, these centers aim to organize researchers from across the disciplines and sectors which, collectively as a research unit, possess the scientific and technical capacity relevant to scientific and technical goals of the sponsoring agencies. In this paper, we measure the productivity and collaboration patterns of university researchers affiliated with a relatively large-scale and “mature” university research center to discern the effects, if any, of the center mechanism on individual scientists and engineers. Based on an analysis of longitudinal bibliometric data, the results from this case study demonstrate affiliation with the center to be effective at enhancing overall productivity as well as at facilitating cross-discipline, cross-sector, and inter-institutional productivity and collaborations.  相似文献

Despite the popularity of big data and analytics (BDA) in industry, research regarding the economic value of BDA is still at an early stage. Little attention has been paid to quantifying the longitudinal impact of organizational BDA implementation on firm performance. Grounded in organizational learning theory, this study empirically demonstrates the impact of BDA implementation on organizational performance and how industry environment characteristics moderate the BDA-performance relationships. Using secondary data regarding BDA implementation from 2010 to February 2020, we find that BDA implementation has a significant impact on two types of business value creation: operational efficiency and business growth. Furthermore, the impact of BDA on operational efficiency is amplified in less dynamic and complex environments, while the BDA-business growth relationship is more pronounced in more dynamic, complex, and munificent environments. Collectively, this study provides a theory-centric understanding of BDA’s economic benefits. The findings offer insights to firms about what actual benefits BDA implementation may generate and how firms may align the use of BDA with the industry environments they are operating in.  相似文献

Co-authorship networks and research impact: A social capital perspective   总被引:1,自引:0,他引:1  
The impact of research work is related to a scholar's reputation and future promotions. Greater research impact not only inspires scholars to continue their research, but also increases the possibility of a larger research budget from sponsors. Given the importance of research impact, this study proposes that utilizing social capital embedded in a social structure is an effective way to achieve more research impact. The contribution of this study is to define six indicators of social capital (degree centrality, closeness centrality, betweenness centrality, prolific co-author count, team exploration, and publishing tenure) and investigate how these indicators interact and affect citations for publications. A total of 137 Information Systems scholars from the Social Science Citation Index database were selected to test the hypothesized relationships. The results show that betweenness centrality plays the most important role in taking advantage of non-redundant resources in a co-authorship network, thereby significantly affecting citations for publications. In addition, we found that prolific co-author count, team exploration, and publishing tenure all have indirect effects on citation count. Specifically, co-authoring with prolific scholars helps researchers develop centralities and, in turn, generate higher numbers of citations. Researchers with longer publishing tenure tend to have higher degree centrality. When they collaborate more with different scholars, they achieve more closeness and betweenness centralities, but risk being distrusted by prolific scholars and losing chances to co-author with them. Finally, implications of findings and recommendations for future research are discussed.  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

Social collaboration technologies have rapidly spread across organizations, offering a unique opportunity to improve the exchange of knowledge among employees, especially in distributed work environments. The increasing popularity of social-collaboration tools as an employee-oriented communication channel, inevitably raises questions about the future of email as its intensive use by knowledge workers is more and more perceived as being inefficient and unproductive. Through a quantitative case study methodology, this study seeks to explore the role played by the notion of habit in explaining employee knowledge sharing capability for firms implementing social collaborative practices in the context of no-email initiatives. Data collected within a large international IT services company, which is among the first firms having made such shift, were used to test the developed conceptual model. The findings suggest that habit is positively influenced by relative advantage and perceived ease of use while relative advantage was found to positively impact knowledge sharing capability. Besides, habit moderates the relationships between three attributes (relative advantage, perceived ease of use, and compatibility to a lesser extent) and knowledge sharing capability. Theoretical and practical implications developed from these findings are then discussed.  相似文献

本文首先采用TOPSIS对科技产出进行评价,得到唯一的产出变量,然后采用面板数据、面板向量自回归模型分析科技投入与产出的互动关系。结果表明,中国高校人文社科研究投入产出的互动关系效应比较明显,形成良性正反馈效应。科研经费、研发人员全时当量与与科研产出之间存在双向格兰杰因果关系。科研人员数是科研产出的格兰杰原因,而科研产出只在滞后1期的情况下,才是科研人员数的格兰杰原因。无论是脉冲响应函数,还是方差分解,各变量除自身外,都是科研产出的影响最大,说明了科研产出对科技投入存在较大的互动作用。对科技产出贡献最大的是科技人员数量,其次是研发人员全时当量,最后是科研经费,最后对原因进行了分析。  相似文献

We test the hypothesis that scientific collaboration is associated with increased publication productivity. We differentiate our approach from other studies by (a) incorporating professional networks in the productivity model, (b) casting productivity and collaboration as distinct phenomena, and (c) examining these phenomena in the context of resource-constrained research institutions in a developing country. We use survey data and employ negative binomial regression models. Results indicate that publication productivity is significantly linked to professional network factors, but there is no evidence of any association with scientific collaboration. We observe that most scientists collaborate in research projects despite coordination difficulties, and without any measurable impact on their productivity. Our interviews reveal that a possible answer to this puzzle appears to be rooted in a practice that views collaborative research projects not mainly as a means to producing knowledge and gaining recognition, but for acquiring professional opportunities and extrinsic rewards. Our findings suggest a new way of modeling publication productivity, with implications for science and innovation policy in both the developed and the developing world.  相似文献

The diffusion of innovations is identified as an important aspect of technological and social change. Innovations diffuse through segmented networks of knowledge that limit the flow of knowledge from any one technological domain to any other. Despite this segmentation, some organizations are capable of developing pieces of knowledge that overcome these limitations. Within this context, we develop four hypotheses regarding specific R&D strategies that affect a firm’s ability to develop inventions that diffuse beyond the firm’s technological boundaries. Specifically, we examine how a firm's scientific intensity, technological collaborations, technological diversity, and internal focus impact breadth of innovation diffusion. We use two of the main determinants of innovation diffusion, namely, the relative advantage and the observability, as theoretical mechanisms to build our arguments. We empirically test our hypotheses on longitudinal data from the industries of pharmaceuticals, biotechnology, and chemicals. Our findings show that the extent to which the knowledge embedded in a firm’s inventions diffuses in distant technological areas is positively related to the firm’s scientific intensity and to its extent of collaboration, but it is negatively related to its technological diversity.  相似文献
