With the rapid development of science and technology, the evolution of industrial technology system has been deepened, and the rise of industrial technology track is more and more important to the technological innovation, and further affects the continuous improvement of innovation performance.This study constructs a theoretical model of the impact of industrial technology track on innovation performance, which is based on mediating variable of the evolution in industrial technology innovation system, to explore the mediating role of the industrial technology system evolution, and according to the survey data, an empirical study on the model is carried out.The results show that the rise of industrial technology track has a significant role in promoting the evolution of industrial technology system, the evolution of the industrial technology system to promote the improvement of innovation performance, the direct impact of the rise of industrial technology track on innovation performance is not significant, need a intermediary role in the evolution of the industrial technology system.%科技发展速度日益加快,产业技术体系演进不断深化,产业技术轨道跃升对技术创新的影响日益突出,并进一步影响创新绩效.由此,构建以产业技术创新体系演进为中介变量的产业技术轨道影响创新绩效的理论模型,探讨产业技术体系演进的中介作用,并对模型进行实证研究.结果表明:产业技术轨道跃升对产业技术体系演进具有显著推动作用,产业技术体系演进能够促进创新绩效提升,产业技术轨道跃升对创新绩效的直接影响不显著,需要通过产业技术体系演进的中介作用.
