军民融合协同创新网络中知识异质性对企业技术生态位的影响研究——基于专利情报分析

The Research on the Influence of Knowledge Heterogeneity to the Technology Niche in the Civilian-Military Integration Collaboration Innovation Network:Based on Patent Intelligence Analysis

[目的/意义]当前,我国军民融合技术创新正处于深度融合发展阶段,优化军民融合企业技术生态位,增强可持续创新能力至关重要。[方法/过程]以2015—2022年我国军民融合概念股上市企业获批专利为研究样本,利用STATA 16.0软件,采用固定效应回归模型,探究知识异质性对技术生态位宽度和重叠度的影响机理以及合作网络中心性的调节作用。[结果/讨论]知识异质性对军民融合企业技术生态位宽度的影响呈倒U型,而对技术生态位重叠度的影响呈U型,但不显著。当网络中心性较高时,适度的知识异质性对技术生态位宽度的作用程度更大。

[Purpose/significance]At present,China’s civil-military integration technology innovation is in the stage of deep integration development.It is very important to optimize the technology niche of civil-military integration enterprises and enhance the ability of sustainable innovation.[Method/process]Taking the patents granted by listed companies of China’s civil-military integration concept stocks from 2015 to 2022 as research samples,this paper uses STATA 16.0 software and fixed-effect regression model to explore the influence mechanism of knowledge heterogeneity on technology niche breadth and overlap and the moderating effect of collaboration network centrality.[Result/conclusion]The influence of knowledge heterogeneity on technology niche breadth of civil-military integration enterprise is inverted U-shaped,while the influence on technology niche overlap is U-shaped,but not significant.When the network centrality is high,the moderate knowledge heterogeneity has a greater effect on the technology niche breadth.
