网络嵌入背景下,企业的研发投入行为受到网络中其他主体的影响.文章针对相同网络位置企业合作研发和不同网络位置企业合作研发两种情形,分别构建技术创新网络内部企业合作研发博弈模型,分析网络结构指标以及网络关系指标对企业合作研发投入的影响.研究表明:企业合作研发投入与规范合作行为的单位成本及企业间位置势差负相关,与网络平均吸收能力及企业中心度正相关.相同网络位置企业合作研发情形下,合作研发投入还与技术溢出正相关,与企业间的竞争程度负相关.

The R\&D investment of enterprise is influenced by other subjects in the network. Aiming at the two situations of cooperative R\&D of enterprises in the same network location and different network locations, this paper constructs different game model, and analyzes the influence of network structure index and network relationship index on cooperative R\&D investment of enterprises. The result of this research shows that R\&D investment is negatively correlated with the unit cost of the normative cooperative behavior and the positional difference between the enterprises. It is positively correlated with the average absorption capacity of the network and the centrality of the enterprise in the network. In the case of cooperative R\&D in the same network location, R\&D investment is positively correlated with technology spillover and negatively correlated with the degree of competition among enterprises.
