技术变迁视角下企业技术生态位对创新能力的影响

Research on the Influence of Technological Niche of Enterprises Innovation Capability from the Perspective of Technological Change

以2013-2017年中国航空航天制造企业专利数据为研究样本,采用泊松回归模型检验了企业技术生态位特征与创新能力之间的关系,并将系统中心生态位作为调节变量检验其对于企业技术生态位与创新能力关系的影响。结果表明:企业技术生态位的宽度及重叠度均与其创新能力呈倒U型关系;系统中心生态位进入正向调节企业技术生态位宽度与创新能力的关系,负向调节企业技术生态位重叠度与创新能力的关系。系统中心生态位深度负向调节企业技术生态位宽度与创新能力的关系,而对技术生态位重叠度与创新能力的关系无显著影响。

With 2013-2017 years' patent data of China's aerospace manufacturing enterprises as research samples, the relationship between technological niche characteristics and enterprises innovation ability is tested by Poisson regression model, the system center niche was used as a regulating variable to examine its impact on the relationship between enterprise technology niche and innovation capability.The results show that the niche width and overlap degree of the enterprise technology niche are in an inverted U-shaped relation with its innovation ability.The central niche of the system positively adjusts the relationship between the width of the enterprise's technology niche and the innovation ability, and negatively adjusts the relationship between the overlap degree of the enterprise's technology niche and the innovation ability.The depth of the central niche of the system negatively regulates the relationship between the width of the technology niche and the innovation capability of the enterprise, but has no significant influence on the relationship between the overlap degree of the technology niche and the innovation capability.
