Abstract：
Combining the expanded Bertschek model with the competition effect, learning cost effect, location effect and absorption and diffusion effect of transportation infrastructure, provincial data from 2006-2016 in China and spatial econometric model are adopted in the analysis of the impact on regional innovation brought about by FDI, OFDI, import and export trade and transportation infrastructure. The results show that FDI, OFDI and export trade can generate significant local innovation spillovers thus positively influence neighboring areas. Transportation infrastructure plays a positive role in FDI’s transformation into local innovation, thus becoming one of the reasons for regional differences in local innovation spillovers in FDI. Innovation spillovers of international trade are more vulnerable to space constraints and transportation infrastructure weakens the spatial attenuation of innovation spillovers. R&D investment, education and Internet penetration bring about local innovation spillover effect, while R&D investment has a significant positive impact on neighboring regions. China should reduce its dependence on high-tech import, cultivate and upgrade brand enterprise and bring the import innovation effect into play. In the meantime, it is a must to narrow down regional differences in transportation infrastructure so as to realize the balance and cooperation in two-way international technology spillover.
