The literature on organizational learning asserts that external learning is often limited geographically and technologically. We scrutinize to what extent organizations acquire external knowledge by accessing external knowledge repositories. We argue that professional service firms (PSFs) grant access to nonlocalized knowledge repositories and thereby not only facilitate external learning but also help to overcome localization. Focusing on patent law firms, we test our predictions using a unique dataset of 544,820 pairs of European patent applications. Analyzing patterns of knowledge flows captured in patent citations, we find that accessing a PSF's repository facilitates the acquisition of external knowledge. As the effect is more pronounced for knowledge that is distant to a focal organization, we conclude that having access to a knowledge repository compensates for localization disadvantages.

Taking a longitudinal approach, we analyze how the evolution of different dimensions of social capital between an SME (Small and Medium enterprise) and its key foreign customers directly influences the firm’s foreign performance growth. Moreover, we utilize a contingency approach by introducing two dyad-specific characteristics into the analysis: psychic and geographic interorganizational distances. Our findings contribute to the international business literature on social capital and suggest that while an investment in social capital with distant foreign customers always reinforces SMEs’ foreign performance development, relational and cognitive social capital have the same positive effects only for low levels of interorganizational psychic distance.  相似文献

The concept of demarketing refers to the use of marketing techniques to reduce or eliminate demand for a product or service. A review of the demarketing literature relating to health and specifically antismoking initiatives indicated that, while research on this topic exists, much of it is not grounded in an acceptable attitudinal or behavioural theory. After determining the importance placed by a sample of 18–24‐year olds on nine demarketing initiatives, two dimensions were identified that best explained this construct. Items within these dimensions were summed and averaged to form single variables, which were then used to form the attitudinal component of the Model of Goal Directed Behaviour. The findings showed that two of these variables – one that captured product packaging aspects and another that consisted of place and price items – significantly influenced the desire to quit and indirectly influenced the intention to quit. Anticipated positive emotions, frequency of quitting attempts and perceived control over quitting also positively influenced the desire and/or intention to quit. The article concludes with a discussion that interprets these findings from a theoretical and practical perspective and suggests directions for future research.  相似文献

Multinational corporations (MNCs) and other foreign firms can be conduits for technology and knowledge (T&K) transfer to host countries in the developing world. Most of the existing research focuses on T&K transfers through FDI and are drawn from Asia not Sub-Saharan Africa (SSA), although SSA is increasingly receiving foreign investment. There is a paucity of research that gives insights into project-level T&K transfer issues in SSA countries. Using the Ghanaian construction industry as an empirical focus, this article explores T&K transfer potential. The findings reveal significant weaknesses in T&K transfer across industry subsectors and between foreign and local firms. This arises from the potentially complementary but dissimilar resource and knowledge bases. The weaknesses are compounded by the absence of coherent government T&K development policies.  相似文献

This article uses a tailor-made new data set of 7 580 251 observations for German exports at the firm-product-destination level to estimate a gravity equation and to investigate the link between the amount of firms’ exports and the distance to destination countries. It is shown that, in line with stylized facts based on aggregate data, the quantity of exports declines significantly with distance within a firm for a given product.  相似文献

引入过程互依性和项目不确定性,探讨了KIBS企业-顾客交互创新中知识整合的权变机制。基于338份服务创新项目问卷数据进行实证研究,结果显示:在KIBS企业-顾客交互四要素中,除规则正式化负向影响外部知识整合以外,决策集体化、资源共享和任务协作均正向影响内、外部知识整合;过程互依性增强了规则正式化、决策集体化和任务协作对内部知识整合的影响,但对资源共享与内部知识整合间关系的调节作用不显著;项目不确定性增强了规则正式化、资源共享和任务协作对外部知识整合的影响,但对决策集体化与外部知识整合间关系的调节作用不显著。  相似文献
