【摘要】：进入21世纪以后,随着企业市场竞争的加剧,技术创新活动的复杂性和重要性同时凸显,创新成为企业赢得竞争优势的关键,同时企业为提升创新绩效不断加大人力、物力、财力的投入。如何提高企业研发投入的利用效率,增加研发投入能否显著提高企业创新绩效成为国内外企业关注的焦点。企业内部创新网络由参与技术创新活动的研发人员构成,影响通过企业内部知识转移与共享而对技术创新产生影响。本文以企业内部创新网络结构属性为视角探讨研发投入对企业创新绩效产生差异影响的原因,对提高企业研发投入利用率,提升企业创新绩效具有深远的现实意义。本文以技术创新理论和知识管理理论为依据,总结了技术创新活动的本质内涵及网络结构对知识转移的影响,引入社会网络分析法研究研发团队网络结构对研发投入与创新绩效调节作用。在梳理国内外相关文献的基础上界定了研发团队网络结构的概念,将其划分为网络密度、网络中心势、E-I指数三个维度,从知识转移角度分析了研发团队网络密度三个维度对企业创新绩效的作用机理及其对研发投入与创新绩效关系的调节效应,建立了以研发团队网络结构为调节变量的研发投入对企业创新绩效的影响模型,同时提出相应的研究假设。选取我国汽车产业157家上市公司为样本进行实证研究,运用描述性统计、相关性分析和多元回归分析对样本数据进行假设检验。研究表明：研发投入与企业创新绩效显著正相关；网络密度、网络中心势对企业创新绩效有显著正向影响,且对研发投入与创新绩效关系调节作用显著；E-I指数负向调节研发投入与创新绩效的关系,但对创新绩效的负向影响不显著,这说明E-I指数不是通过影响知识转移而调节研发投入与创新绩效的关系。根据研究结果,本文提出如下管理对策与建议：(1)增加研发人员投入是提高企业创新绩效的基础；(2)完善研发团队网络结构,提高研发投入利用率。企业创新绩效的提高是一个系统同程,在增加研发投入的同时,加强企业内部网络结构建设,充分发挥研发团队网络结构在研发投入对提升企业创新绩效过程中的作用。期望本文的分析与探讨能进一步充实研发投入与企业创新绩效关系的研究,为企业的管理实践带来一定的指导意义。
[Abstract]:After entering the 21st century, with the aggravation of the competition in the enterprise market, the complexity and importance of the technological innovation activities are highlighted at the same time, innovation becomes the key for the enterprise to win the competitive advantage, at the same time, the enterprise increases the manpower and material resources in order to promote the innovation performance. Financial investment How to improve the efficiency of R & D investment and whether it can significantly improve the innovation performance has become the focus of domestic and foreign enterprises. Intra-enterprise innovation network is composed of R & D personnel involved in technological innovation activities, which has an impact on technological innovation through knowledge transfer and sharing within enterprises. This paper discusses the causes of the difference between R & D investment and enterprise innovation performance from the perspective of the attribute of internal innovation network structure. It has far-reaching practical significance to improve the utilization rate of enterprise R & D investment and enhance enterprise innovation performance. Based on the theory of technological innovation and knowledge management, this paper summarizes the essence of technological innovation and the influence of network structure on knowledge transfer. Social network analysis was introduced to study the regulatory effect of R & D team network structure on R & D investment and innovation performance. This paper defines the concept of network structure of R & D team on the basis of combing related literature at home and abroad, and divides it into three dimensions: network density, network center potential and E-I index. From the perspective of knowledge transfer, this paper analyzes the mechanism of the three dimensions of R & D team network density on enterprise innovation performance and its regulatory effect on the relationship between R & D investment and innovation performance. In this paper, a model of the influence of R & D investment on enterprise innovation performance is established, which takes R & D team network structure as the adjusting variable, and the corresponding research hypothesis is put forward at the same time. In this paper, 157 listed companies in China's automobile industry are selected for empirical research, and the sample data are tested by descriptive statistics, correlation analysis and multivariate regression analysis. The results show that R & D investment has a significant positive correlation with enterprise innovation performance, network density and network center potential have a significant positive impact on enterprise innovation performance, and the relationship between R & D investment and innovation performance is significantly regulated. E-I index negatively regulates the relationship between R & D investment and innovation performance, but the negative impact on innovation performance is not significant, which indicates that E-I index does not regulate the relationship between R & D investment and innovation performance by influencing knowledge transfer. According to the research results, this paper puts forward the following management countermeasures and suggestions: (1) increasing R & D personnel input is the basis of improving enterprise innovation performance; (2) perfecting the network structure of R & D team and improving R D investment utilization ratio. The improvement of enterprise innovation performance is a systematic process. In addition to increasing R & D investment, we should strengthen the construction of internal network structure and give full play to the role of R & D team network structure in the process of R & D investment in the process of improving enterprise innovation performance. It is expected that the analysis and discussion in this paper can further enrich the research on the relationship between R & D investment and enterprise innovation performance, and bring some guiding significance to the management practice of enterprises.
