This paper analyses the causality between inventor productivity and inventor mobility. The results show that the level of education has no influence on inventor productivity. Making use of external sources of knowledge, on the contrary, has a significant effect on productivity. Finally, firm size has a positive impact on productivity. Firm size also influences inventor mobility, although negatively. Whereas existing research implicitly assumes causality to point in one direction, this study ex ante allows for a simultaneous relationship. To deal with the expected endogeneity problem, instrumental variables techniques (IVREG and IVPROBIT) will be employed. Results show that mobile inventors are more productive than non-movers. Whereas a move increases productivity, an increase in productivity decreases the probability to observe a move.  相似文献

发明家网络中结构洞填充的影响因素研究   总被引:1,自引:0,他引:1       下载免费PDF全文
企业内部发明家合作创新网络中的结构洞对提高发明家的创新绩效有着重要作用,这在西方个人主义文化中得到了广泛论证。而近来的研究表明,在中国的集体主义和儒家传统文化中,填充结构洞才能得到更高的绩效。在此背景下,基于13家中国高新技术企业的专利数据,研究了这些企业内部研发团队的网络结构(社会资本)差异和成员特征(人力资本)差异对结构洞填充的影响。研究发现,团队的网络中心性差异和地位差异均对结构洞的填充产生显著正向影响;团队的知识范围差异与结构洞填充之间存在倒U型关系。  相似文献

We investigate the impact of deadly terrorist attacks on inventor productivity and mobility in the U.S. During the five-year window after such events, nearby firms generate fewer and less impactful inventions. Moreover, their inventors typically exhibit a post-attack decline in their patent production, unless they move to a distant company (which some tend to do after an attack). Firms' financial constraints and inventor talent appear to provide channels underlying our productivity and mobility findings, respectively. These results provide novel insights about the impact of shocks that distort the invention process and promote the mobility and reallocation of inventors among firms.  相似文献

网络功能取决于网络的结构,网络结构则是由网络上的个体行为决定的,因此网络功能的优化须从网络上个体行为的优化着手.本文以豆瓣社区中个体的读书时间序列数据、关注其他用户的序列数据及参加小组的关系数据,进行两两关系序列数据间的相关性分析,由此得出个体嵌入网络的行为过程.通过对比有创新能力的个体组与无创新能力的个体组的行为过程,发现有创新能力的个体有个体网络的嵌入,无创新能力的个体则没有网络嵌入.研究结论表明个体的网络嵌入行为可以按有创新能力个体的嵌入网络的方式进行优化,同时在研究方法上,整个研究过程体现了扎根理论研究中尊重数据,尊重过程的研究范式,这为规范过程网络研究及优化网络结构、改善网络功能的研究做了开创性尝试.  相似文献

We examine the impact of local and foreign labor mobility in India by modeling one regional and one global network, each of which captures the inter-organizational mobility of inventors. Our analysis of the regional network shows that, within India, the productivity of inventors does not improve when they move from foreign to Indian organizations. In the global network, we find that Indian organizations remain located in the periphery as a result of employing a small number of inventors from foreign organizations. However, in the instances when inventors are hired from foreign organizations, they are able to produce patents with a higher impact in comparison to inventors hired from other Indian organizations. Furthermore, when the inventors are hired from abroad, the impact of their patents is even higher in comparison. The implications of these findings for innovation and policy in the emerging economy context are discussed.  相似文献

目前,我国个人消费信贷市场空间不断拓展,住房信贷、汽车信贷、耐用消费品信贷、助学信贷等业务获得迅速发展。2000年,全国金融机构贷款余额增加1.33万亿,同比增长14.3%,其中消费贷款累计增加2,592亿元,比1999年多增加1,693亿元,占全部金融机构各项贷款增加额的68%,在全年贷款总增长额中的贡献率为19.7%。随着消费贷款规模的不断扩大,该项业务中存在的问题和风险也逐步暴露出来,在有些地区还表现得比较明显,商业银行应加强对消费信贷风险的分析与识别,以便及时采取措施,防范消费信贷风险。  相似文献

This paper investigates the influence of departmental level characteristics and resources on individual involvement with industry using a national survey of STEM faculty. An integrative model of industry involvement is developed and tested that integrates a multi-level perspective on university–industry relations. Three measures of industry involvement are tested: the amount of time a researcher spends with industry, the number of activities a researcher engages in, and the intensity of those activities. Results of the model show that the quality of human capital in a researcher's home department is a significant influence on industry involvement. Non-federal R&D expenditures and direct industry funding also positively increase the likelihood of industry involvement. Policy and managerial implications of the results are discussed.  相似文献

Do informal social ties connecting inventors across distant places promote knowledge flows between them? To measure informal ties, we use a new and direct index of social connectedness of regions based on aggregate Facebook friendships. We use a well-established identification strategy that relies on matching inventor citations with citations from examiners. Moreover, we isolate the specific effect of informal connections, above and beyond formal professional ties (co-inventor networks) and geographic proximity. We identify a significant and robust effect of informal ties on patent citations. Further, we find that the effect of geographic proximity on knowledge flows is entirely explained by informal social ties and professional networks. We also show that the effect of informal social ties on knowledge flows is greater for new entrepreneurs or ‘garage inventors’, for older or ‘forgotten’ patents, and for flows across distant technology fields. It has also become increasingly important over the last two decades.  相似文献

The management of research productivity is central to university governance and drives a broad range of decisions, including those on hiring, promotion and funding allocation. Policymakers and academic leaders responsible for improving their institutions’ research performance need an evidence-based understanding of the organizational factors that can be managed in pursuit of better publication outcomes. Our paper reviews the empirical evidence on the drivers of research productivity that can be actively managed by organizations and policymakers. Such drivers include organizational structures, research culture, features of task environment for academic work, and resource allocation. To advance the state of science in research productivity literature, we then analyze assumptions and highlight mechanisms that need to be explored in order to improve theoretical and methodological state of the field. We suggest directions for future research with the aim to create a deeper and more cohesive body of knowledge on how organizations, funding bodies, and government agencies can influence scientific performance at the individual level. To advance the practice of research management, we offer a rigorous synthesis of existing empirical evidence that can help academic leaders in supporting and developing faculty research productivity within their institutions.  相似文献
