The Effects of Technological Spillover through FDI and Import Trade on China's Innovation

摘要

Based on the state space equation of time-varying parameter model, this paper analyzes the effects of different R&D and human capital on China's innovation, making empirical analyses with 1990-2005 data. The result shows that China's innovation ability mainly depends on domestic R&D input, but there is the downtrend in recent years; foreign R&D embodied in FDI stimulates the innovation of China, and the effect raises slowly recently; import trade blocks the upgrade of innovation,but the effect of hindrance is descending recently; human capital doesn't get the lowest threshold which is needed in host country by technical diffusion through FDI.
