【摘要】 随着世界经济一体化进程的深入,网络化模式的产品开发、生产制造、物流运输、销售服务的趋势愈来愈强。然而大部分的中国企业在全球化的分工体系中长期处于低价值的制造环节,在新产品开发的关键环节上处于相对劣势。如何利用企业所处网络中的资源有效地开展新产品开发工作从而跃迁到价值链的高端,实现由中国制造到中国创造的转变,是我国企业所面对的一个重大而现实的课题。在激烈的市场竞争和动态变化的经营环境下,学者们认同企业所嵌入的网络对其创新与产品开发具有重要的影响,网络已经逐渐成为当前企业营造核心竞争力和提高经营绩效的重要手段。为快速响应研发制造全球化与组织网络化的发展,企业需要积极从内部转到全方位利用各种知识网络(知识源)来进行新想法、新技术与新知识的获取,并通过消化吸收进入企业内部,同时加以融合运用,促进企业新产品开发与企业现有与新问题解决,进而推进其持续发展。这也使得在知识经济时代全球化发展与我国本土企业转型升级背景下,对“企业应选择什么样的网络联结模式与结构,以最大限度地改善其知识管理效果,进而提升其新产品开发绩效?”问题的研究就显得尤其重要。本文首先在前人研究的基础上对这一基本问题进行了解构,将该问题分解成为三个子问题来研究：即在知识管理与新产品开发过程中,(1)企业网络将如何影响企业的新产品开发绩效?(2)企业如何在不同情境下构建有效的网络模式以提升其新产品开发绩效?(3)企业该如何动态配置网络以持续地提升其新产品开发绩效?接着笔者对与本文研究问题相关的企业网络、知识管理、环境动态性、新产品开发绩效等理论研究文献进行了综述。基于此,笔者构建了本文的整体理论研究框架以及预设假设基础上的两个研究模型。随后分别进行了企业网络、知识管理及新产品开发绩效之间关系的结构方程建模分析,以及在权变视角下通过环境动态性调节企业网络与知识管理之间的多元线性回归分析,回答了本文所提出的前两个子问题。继而笔者开展了企业网络与知识管理及新产品开发绩效动态演化的典型性案例研究,即采取规范的案例研究方法,选取了宁波裕人针织机械有限公司作为典型个案,验证性地分析该公司如何根据不同的环境变化,将企业网络与知识管理有效地动态匹配起来,更好地提升其新产品开发绩效,从而也回答了本文所提出的第三个子问题。在三个子问题回答后,本文提出的基本研究问题也得以解答。通过全文的分析论证,验明并形成了以下主要研究结论：(1)知识管理对提升新产品开发绩效产生了积极的促进作用,知识获取、知识吸收、知识重用均对新产品开发绩效具有积极的促进作用。企业需要加强知识的获取、吸收和重用,注重培养与强化,对提升新产品开发绩效发挥更大的促进作用。(2)企业网络对知识管理产生直接的正向影响作用,说明企业网络特性越好,越有利于增进知识管理效果。联结强度分别对知识获取、吸收、重用产生直接正向影响作用,表明提高企业网络成员间的交流合作频率将有助于增进其知识获取、吸收、重用效果。联结集中度分别对知识获取、吸收产生直接正向影响作用,表明网络内越是拥有高集聚式联结关系的企业间的交流合作越有助于增进其知识获取、吸收效果。联结久度对知识获取、吸收、重用产生直接正向影响作用,表明提高企业网络成员间交流合作频率将有助于增进其知识获取、吸收、重用效果。网络规模对知识获取和重用产生直接正向影响作用,表明越是拥有多成员的企业网络,成员间的交流合作越有助于增进其知识获取和重用效果。网络异质性分别对知识获取、重用产生直接正向影响作用,说明合作伙伴及其资源类型差异性越高,网络内企业的交流合作越有助于增进其知识获取和重用效果。(3)企业网络对新产品开发绩效产生了间接的促进作用,这种作用是通过知识管理的传递而产生,知识管理成为了企业网络促进新产品开发绩效的中介因素。即企业网络特性中的联结强度、联结集中度、联结久度、网络规模、网络异质性正向影响新产品开发绩效均是经由知识管理(获取、吸收和重用中的二项或全部)的传递而间接发生作用的。因此,应大力强化企业网络特性,努力建构具有网络联结强度高、联结集中度高、联结久度高、规模大、异质性高的企业网络,并应尽可能地提高知识获取、吸收和重用能力以增进知识管理效果,通过这两方面的联动与动态协同从而有效地提升新产品开发绩效。(4)环境动态性在企业网络影响知识管理的机制中发挥了调节作用,即环境动态性在企业网络特性中的联结强度、联结集中度、联结久度、网络规模、网络异质性分别对知识管理的影响关系中起了调制作用。环境动态性在联结强度、联结集中度、联结久度、网络规模与知识管理之间影响关系中均起了负向的调节作用。环境动态性越高,越易削弱其对知识管理的正向影响作用,这需尽可能地消除环境快速变化及其不确定性因素给合作交流带来的不利影响,使得联结强度、联结集中度、联结久度越高以及网络规模越大的网络能更有助于增进网络内成员企业合作交流时的知识管理效果进而提升新产品开发绩效。环境动态性在网络异质性与知识管理之间影响关系中则起了正向的调节作用,即环境动态性越高,越易强化其对知识管理的正向影响作用,这需更好地把握动态环境快速变化中新出现的产品开发与创新机会,增进动态环境快速变化中新技术与新知识的传播与扩散,使得异质性越高的网络能更有助于增进网络内成员企业合作交流时的知识管理效果进而提升新产品开发绩效。在知识经济时代全球化发展以及我国本土企业转型升级背景下,本文研究所得出的这些重要结论,对于融入网络中进行交流合作的我国企业的知识管理与新产品开发实践提供了重要的现实指导意义,同时也对企业网络、知识管理与组织学习及新产品开发的相关理论研究进行了重要的补充与完善。更多还原

【Abstract】 With the in-depth development of the global economy integration, the trend prevails of product development, manufacturing, logistics and sales service in network. However, most of the Chinese enterprises are in a manufacturing position which is the lower value end in the global labor division system and show weakness on the key point of new product development. It is important for Chinese enterprises to develop new products effectively with the interfim network embedded so as to ascend to the high end of the value chain and transform from that with products"Made in China" to "Innovated in China". In a intensively competitive and dynamic environment, scholars acknowledge that the interfirm network embedded within enterprises plays an important role in its innovation and new product development and as a matter of fact, interfirm network has become an increasingly important means to build its core competence and improve tis operating performance. To feedback rapidly on the R&D and manufacturing global development and organization network development, enterprises need to transform from taking the advantage of internal network to comprehensive network to acquire new conception, new technology and new knowledge, absorb them inside the enterprise and share, deploy and develop them so as to speed up the new product development and existing and new problem resolution and facilitate its sustainable development. This has led to the particular necessity and importance of the study that "What kind of network tie model and structure an enterprise should choose to maximize its improvement of knowledge management so as to upgrade its new product development performance" in an era of knowledge economy with the economic globalization and local Chinese enterprise transformation and upgrade.This dissertation is conducted on this question. It first subdivides the basic question into three sub-questions, that is, in the process of knowledge innovation and new product development, (1) How interfirm network influences new product development performance? (2) How enterprises build effective network to upgrade its new product development performance under different situation? (3) How enterprises dynamically deploy its network to continuously upgrade its new product development performance? It is followed by the theory summaries of interfirm network, knowledge management, environmental dynamism and new product development performance related to this topic based on which the entire theoretic framework and two models on the hypothesis is set up. Then the structural equation modeling analysis of the relationship of interfirm network, knowledge management and new product development performance and multiple linear regression analysis of the relationship between the interfirm network and knowledge management mediated by the environmental dynamism from the contingency perspective has been conducted by the author, which eventually has answered the first two questions. Then, a typical case study is conducted on the dynamic resolution of interfirm network, knowledge management and new product development performance. That is, with a regular case study method, the case of Ningbo Yuren Knitting Mechanical Co. Ltd. is selected to study empirically how the company dynamically matches its network with knowledge management effectively so as to improve its new product development performance according to the environment changes, which has accordingly answered the third question. With all these three sub-questions answered, the basic question raised at the beginning of this thesis has been resolved as well and the major conclusions of the study through the analysis conducted in the dissertation is summarized as follows,Knowledge management facilitates the improvement of new product development performance. Furthermore, knowledge acquisition, absorption and reuse as of knowledge management all plays proactive role in the enhancement of new product development performance. The capabilities above within the enterprise should be addressed by the enterprise, attentively fostered and enhanced so as to be able to play more important role in the improvement of new product development performance. The features of interfirm network have direct positive effect on knowledge management, which indicates the better the features, the better the effect of knowledge management is enhanced. To be specific, the network tie strength has direct positive effect on knowledge acquisition, absorption and reuse which indicates to improve the frequency of communication and cooperation between members in the network will enhance their knowledge acquisition, absorption and reuse. Network tie centrality plays direct positive role in knowledge acquisition and absorption. This can be interpreted as the higher network tie centrality member enterprises have the better the effect of knowledge acquisition and absorption by enterprises through communication and cooperation. The network tie duration has direct positive effect on knowledge acquisition, absorption and reuse. That is, to stretch the time for the communication and cooperation between members of the network will enhance the effect of their knowledge acquisition, absorption and reuse. The network size has direct positive effect on knowledge acquisition and resue which means to have communication and cooperation between more enterprise members of the network will enhance their knowledge acquisition and resue. The network heterogeneity has direct positive effect on knowledge acquisition and reuse which means the higher diferences among the members’resources in their communication and cooperation, the better the effect of their knowledge acquisition and reuse.The features of interfirm network indirectly facilitate new product development performance. This facilitation is realized through the transferring of knowledge management. Therefore, knowledge management has become the intermediary factor of the interfirm network features facilitating new product development performance. That is to mean it is through the transfer of (two or three of the knowledge acquisition, absorption and reuse) knowledge management that the features of interfirm network including network tie strength, network tie centrality, network tie duration, network size and network heterogeneity positively correlating to new product development performance play its indirect facilitating role. Therefore, it is encouraged to put great efforts to enlarge the features of interfirm network, build the network with intensive tie strength, high centrality, long sustention, large size and more heterogeneity, and try best to improve the capacity of knowledge acquisition, absorption and reuse so as to enhance the effect of knowledge management. With the interaction and dynamic synergy between these two aspects, the new product development performance should be improved effectively.The environmental dynamism plays a mediating role in the mechanism that the features of interfirm network affects knowledge management. That is, while he network tie strength, network tie centrality, network tie sustention, network size and network heterogeneity have respective effect on knowledge management, environmental dynamism plays mediating role in the turnout. To be specific, the environmental dynamism has negative effect on the influence of knowledge management exerted by network tie strength, network centrality, network tie sustention and network size which means the more dynamic the environment, the more negative impact on knowledge management. This calls for the dismiss as far as possible the adverse influence on the cooperation and communication caused by the fast environment changes and uncertain factors attached, so as to facility knowledge management in cooperation and communication between interfirm network members with more intensive interfirm network tie strength, higher network tie centrality and longer network tie sustention and larger network size and furthermore improve the new product development performance. Environmental dynamism plays positive mediating role in the relationship between the network heterogeneity and knowledge management, which means the more dynamic the environment, the more enhancement on the positive influence on knowledge management by network heterogeneity. This calls for the better grasp of the opportunities of product development and innovation and reinforcement of the transmission and dissemination of new technology and new knowledge emerging in the fast changing dynamic environment so as to facilitate knowledge management in the cooperation and communication between network members with more heterogeneity of the environment and furthermore to improve the new product development performance.In an era of knowledge economy with the global development and local Chinese enterprise transformation and upgrade, these important conclusions drawn from the studies above show significant and realistic instruction on the practice of knowledge management and new product development for Chinese enterprises communicating and cooperating in network. Meanwhile, it is also not difficult to find that this dissertation also provides important supplementation and completion on the related theories of interfirm network, knowledge management and organizational learning as well as new product development.更多还原
