Abstract: Based on the perspective of innovation value chain,this paper divided the innovation process into three stages: knowledge innovation, scientific research innovation and product innovation.According to the logic and mechanism of different technological sources affecting the innovation value chain, variable selection and spatial econometric model construction are conducted to explore the space spillover effect and the “synergy” or “crowding-out” effect of factors in the process of driving R&D elements. The results show that there is a clear spatial dependency relationship among the three stages of innovation. Elements of different technological sources at home and abroad can promote the improvement of innovation value chains within the region(direct effect), and also through space spillover effects promote the upgrade of innovation value chains in adjacent areas (indirect effects). The influence channel of technology introduction shows that human capital mainly absorbs the overflows of R&D brought by technology introduction through internal channels, and R&D capital shows more “synergistic effect”.
