【摘要】 21世纪以来，随着信息技术革命的推动和全球市场竞争的加剧，企业正迫切寻找有效的技术创新方法。技术创新网络出现，为企业技术创新提供了更加有利的外部环境，企业越来越依赖网络联结来达到技术创新的完成。由于技术创新网络内各个企业(结点)所处的网络地位不同，所占有的知识资源的不均匀，必然会导致一部分企业成长速度快于其他企业，成为该网络内的核心企业。核心企业的形成将极大的刺激网络内知识、技术的流动，大大提高网络内技术创新水平。然而，在当前，关于技术创新网络中核心企业形成的问题，特别是核心企业是如何利用网络联结关系，获取外部知识资源问题还大大欠缺。鉴于核心企业在技术创新网络中的重要性，本文从网络联结视角出发，通过引入网络联结的强度(联结强度)、网络联结的信任度(信任度)及知识基差异变量，把这三者与核心企业知识获取纳入到共同的研究框架，主要目的在于探求影响核心企业知识获取实现的关键要素及要素间的相互关系。本文首先对相关理论和文献综述，提炼出了技术创新网络核心企业、知识基差异、联结强度、信任度、知识获取间关系的研究框架，提出研究假设，并设计了研究所涉及的各个因素的测量指标和调查问卷，利用调查获得数据对本文提出的模型及假设进行验证，本文提出的模型总体上都得到了验证。本文所作的创新意义工作与研究结论如下：第一，对核心企业形成进行了合理的解析。站在知识观的视角，引入知识基的概念，更好的把握了核心企业与其他企业的本质差别，能更准确的理解核心企业知识获取问题。第二，发现与验证了知识基差异与核心企业知识获取间存在倒U型关系。充实了目前关于知识转移或获取方面的理论研究，即核心企业与合作伙伴知识基差异适度时将最有利于知识获取。第三，深入研究了联结强度与知识获取间悖论，提出与验证了联结强度与知识获取间存在倒U型关系，这在一定程度上解释了这个悖论。结合不同程度联结强度的优劣势，提出核心企业应根据合作企业间知识基差异度来选择适当的联结强度来达到高效率知识获取。第四，验证了信任度与核心企业知识获取间存在正相关关系。这给现实企业管理者如何更有效获取知识提供了较好的参考建议。第五，在分析验证信任度、联结强度对于知识获取有直接影响的基础上，揭示与验证了信任度与联结强度对于知识基差异存在的中介效应。信任度与联结强度的提高将大大降低由于知识基差异所带来的知识获取困难，这是对以往研究的补充与发展。可以看出本文结合了我国技术创新网络中核心企业的实际情况，提出了如何利用网络联结来达到核心企业知识高效获取的一系列可行建议，这对于技术创新网络内其它企业同样具有指导和启示意义。【关键词】技术创新网络核心企业网络联结联结强度信任度知识基差异【论文类型】应用基础本研究得到国家自然科学基金“基于耦合关系的技术创新网络核心企业(集团)形成机理与实证研究”(70672089)资助更多还原

【Abstract】 In the 21st century, with the impel of information technology revolution and the competition of global market being more and more intensive, it is of great importance for enterprises to seek efficient ways of technology innovation. The emergence of technology innovation network provides useful external environments for enterprises’ technology innovation, and enterprises depend more and more on their network ties to achieve their technology innovation process. Due to the different situations of enterprises’ (hub) rent status in the network, enterprises possess uneven knowledge resource, with the result being that some enterprises grow more rapidly compared to other enterprises in the network, and turn into focal (core) enterprises. The emergence of focal enterprises will greatly stimulate the knowledge and technology flow, and enormously raise the level of technology in the corresponding network. However, at present, studies on the emergence of focal enterprise, especially the issues of how focal enterprises take advantage of network ties to acquire external knowledge, are seldom seen.In view of the importance of focal enterprises in technology innovation network, starting from the perspective of network ties, the three concepts of network’s tie strength (tie strength), network tie’s trust (trust) and knowledge base difference, were combined into one research frame work, together with focal enterprise’s external knowledge acquisition. The main aim of this research is to seek the key elements and the relationships among them for effective knowledge acquisition. Based on the literature review, the model is constructed with its main elements being technology innovation network’s focal enterprises, tie strength, trust, and knowledge acquisition. Correspondingly, five hypotheses are put forward, and then the constructed factors’ measurement and questionnaire are designed. The model and hypotheses are tested by use of data set from 115 samples. The model is fully supported in this research. The innovation in this paper can be summarized as the following:First, the emergence of focal enterprise is logically interpreted. Based on the view of knowledge, the concept of Knowledge Base is introduced, which grasps the underlying difference between other non-focal enterprise and the focal enterprise, and can also make the focal enterprise external knowledge acquisition problem better understood.Second, the non-linear relationship between the knowledge base difference and the focal enterprises’ external knowledge acquisition is discovered and tested, with the conclusion enriching present researches on knowledge transfer or knowledge acquisition that is the best situation for knowledge acquisition when the knowledge base difference between focal enterprise and other non-focal enterprise is proper.Third, the paradox between tie strength and knowledge acquisition is deeply studied. What’s more, the non-linear relationship between tie strength and knowledge acquisition is brought forth and tested, with explained the paradox in some degree. Considering that the different tie strength has its own advantage and disadvantage, the conclusion is reached that the focal enterprise should choose suitable tie strength to acquire external knowledge efficiently, basing on the collaborators’ knowledge base difference .Forth, the positive relationship between trust and focal enterprises’ knowledge acquisition is tested, which gives enterprise’s supervisors good advices on how to acquire external knowledge.Fifth, based on analyzing the direct effect of trust and tie strength on knowledge acquisition, the mediate effect on knowledge base difference is exploited and examined, which enriched and broadened the past researches.It can be seen that this research is based on the practical situation, and puts forward a series of suitable advises on how to make fully use of network ties to get knowledge efficiently for focal enterprises. Furthermore, the conclusions also give some guidelines and enlightenments to other non-focal enterprises in the technology network.更多还原
