不同网络嵌入方式对企业创新绩效的影响是存在显著差异的。构建了网络嵌入、学习能力和技术创新绩效之间的理论模型,通过运用结构方程模型对广东省高新技术与民营科技型企业为样本的问卷调查数据进行实证分析。研究结果表明:(1)网络结构嵌入对技术创新绩效没有直接的显著影响,也无法通过学习能力的中介对其产生间接的影响作用;(2)网络关系嵌入对技术创新绩效不仅有直接显著的正向影响,而且还能通过学习能力的部分中介作用对技术创新绩效起到显著的正向影响;(3)在小规模企业中,网络密度对于技术创新绩效的作用并不显著。研究结论进一步深化了技术创新理论,对企业技术创新的提升有一定指导意义。 相似文献

组织合作网络结构对企业绩效的影响有两类相反的作用机制：网络闭合和网络开放。论文认为,哪种机制起作用取决于企业所面临的创新任务以及知识来源在网络中的位置。基于汤森路透、USPTO和Compustat三个数据库,论文构建1990-2001年生物技术和医药产业追踪数据,采用社会网络分析方法、固定效应和随机效应模型对此问题进行实证研究。结果发现,战略联盟网络密度增加和结构洞指标增加会负向影响企业技术创新数量,正向影响企业技术创新质量;网络结构调节着直接联盟关系和间接联盟关系对企业技术创新的影响。 相似文献

The current study analyzes the processes involved in obtaining technological innovations. Conclusive results are lacking in the literature, so this work defines and empirically tests a model of the relations between the firm's innovative capacity and the different ways of accumulating knowledge and the decision whether or not to codify it. Also, the model takes into account whether the innovations obtained are radical or incremental.The empirical study uses a sample of Spanish biotechnology firms, and the results show that accumulating knowledge using internal sources and not codifying it significantly improves the firm's capacity to develop radical innovations. The results also show that knowledge codification speeds up the development of incremental innovations. The relation between incremental innovations and the sources of knowledge is not so clear, although the results suggest the possible existence of a nonlinear relation between the two variables. 相似文献

The paper presents and empirically applies a neo-Schumpeterian model of innovation capable of studying interactions between service providers, patients and policy makers, and how these complex interactions determine the timing, direction, and success of innovations in the public sector. The model is tested using a case study that traces the introduction and development of ambulatory surgery in a Spanish hospital. The multi-agent model applies the ideas of Schumpeter to services, encompassing Schumpeter's five types of innovation, and re-introducing the policy-maker as a key agent in the innovation process. The model has a number of advantages over previous, reduced form models. First, it can analyse the interactions between the economic, social and political spheres that make up the complex selection environment of innovations. Second, it captures the recursive impact of radical innovations on agents’ competences and preferences, and their relative power. This brings politics, power, and rhetorical persuasion to the fore. Third, it provides an improved set of definitions for radical and incremental innovation. These are not only important for understanding the sources and drivers of innovation, but also for the accurate measurement of innovation. 相似文献

尽管客户对产品创新的作用已被广泛研究,但是从客户组合层面上来探讨其与创新的关系的研究还较少,以社会网络理论和知识基础观为理论基础,探讨了客户组合的异质性与关系嵌入水平对产品的突破性创新和渐进性创新的影响机制及结果。研究结果表明:客户组合的异质性通过促进客户知识的多样性从而对产品的突破性创新产生积极影响;客户组合的关系嵌入水平通过促进客户知识的深度和专用性从而对产品的渐进性创新产生积极影响。为企业有目的地进行客户组合管理并以此为源动力积极推进产品创新提供了理论依据。 相似文献

This paper investigates different types of innovations (from radical to incremental) in the pharmaceutical industry by studying bibliometric data of drugs approved by the United States Food and Drug Administration (FDA), looking at time-to-market aspects, knowledge sources of these innovations, and protection strategies. Scientific knowledge stemming from the public sector is found to be important for all innovations. Nevertheless, radical innovations build on a higher degree on basic research, and they build on a significantly higher share of own prior scientific research than do incremental innovations. Furthermore, each drug is shown to be accompanied by, on average, about 19 journal publications and 23 additional patents. Additional patent filings peak when the commercialization of the drug is in reach. Firms do not differ among the various types of innovations regarding the amount of additional patent filings, but rather with the speed of filing these patents. Finally, this work contributes to the improvement of future econometric analyses that aim to link bibliometric indicators such as patent or publication counts to firm success. 相似文献

学界关于变革型领导下属创造力之间的关系尚未达成一致,负相关、不相关、正相关的观点均存在。为深入理解二者关系,基于社会认知理论,引入创新自我效能作为中介机制,将成就导向作为边界条件,构建被调节的中介模型。以某汽车企业341名员工及其领导为研究对象,运用多元回归和Bootstrap法进行假设检验。研究结果表明,①智力激发仅与突破性创造力正相关,鼓舞性激励仅与渐进性创造力正相关,理想化影响力、个性化关怀均与突破性创造力、渐进性创造力正相关；②创新自我效能中介①中所有正相关关系；③成就导向调节创新自我效能与突破性创造力、渐进性创造力之间的正相关关系；④成就导向调节②中所有中介关系。 相似文献

By introducing the concept of innovation regimes, the aim of this article is to show how the rapid pace of technological development in the telecom sector may be explained by the close links between the sector's own R&D and the creation of numerous innovations, many of which are radical. In contemporary innovation theory, a theoretical antinomy exists: Whereas, the creation of incremental innovations is variously explained in terms of «rational» responses to markets, dynamics of technological regimes, dominant design, etc., radical innovations, in contrast, are explained in terms of serendipity, chance or haphazard scientific discoveries. Evidence from analysis of innovations in the telecom sector suggests that innovation regimes have provided a capability of coordination, direction and leadership in the creation of many of the radical technological innovations that have emerged in the sector. Thus, one may claim that the strong innovation regimes and high R&D intensity of the telecom sector, at least until recently, have provided a capability of creating innovations on purpose — for a purpose. The policy implications of this contradict some of the assumptions on which the prevailing market-oriented R&D governance models and policies are based — and which are supported by contemporary innovation theories. 相似文献

How much do specialists have to learn from each other when they jointly develop radical product innovations? 总被引：1，自引：0，他引：1
Christina Schmickl 《Research Policy》2008,37(3):473-491
Specialists of different domains have to collaborate whenever technically demanding product innovations are developed. Their respective knowledge contributions need to be integrated into a functioning whole. Two approaches provide insight into how this is achieved: the dominating cross-learning approach assumes that the specialists of different knowledge domains have to intensively learn from each other in order to be able to jointly develop the new product. This cross-learning implies that groups of specialists transfer their specific knowledge, which encompasses different concepts (theories), methods and world views, among each other. However, some researchers argue that intensive cross-learning between specialists is a considerable expense in time and effort and, therefore, inefficient. They insist that integration of specialists’ knowledge is achieved through structural mechanisms that significantly reduce the need for cross-learning. This article is based on one of the latter approaches. We argue that the mechanisms of transactive memory, modularization and prototyping in combination can considerably reduce knowledge transfers. This assumption has found empirical support for incremental innovations. On the basis of a comparison between incremental and radical innovation projects in an electrotechnical company, we analyze whether the assumption that, on the basis of structural mechanisms, specialists can integrate their knowledge without having to intensively learn from each other, also holds for radical innovations. 相似文献

网络关系强度与企业技术创新绩效——基于探索式学习和利用式学习的实证研究 总被引：1，自引：0，他引：1
网络强弱关系被视为影响企业技术创新的重要因素,然而简单考察网络关系与技术创新两个变量的相关关系并没有获得一致结论,形成了“关系嵌入性悖论”。以探索式学习和利用式学习为中介变量,提出了网络关系强度对企业突破性创新和渐进性创新的两面性作用的假设,构建了网络关系强度对技术创新影响的概念模型,并进行了实证研究。实证分析结果表明：创新网络关系强度的提高不利于突破性创新,但有利于渐进创新的提升,其中网络关系强度通过探索式学习对突破性创新产生负面影响,但通过利用式学习对渐进性创新产生正面影响。对此做了进一步讨论并提出了未来研究的若干展望。 相似文献
