Abstract: International trade and FDI are two important ways that show international technology spillovers. The research employs the ridge regression approach and obtains the following empirical results. First, in an open economy, the intensity of present protection of intellectual property in China have positive role on the technology spillover effects of foreign trade and foreign investment, and FDI is more sensitive to the intellectual property protection system. Second, domestic R&D input has significantly promoted the technological progress. Third, the international technical spillover and diffusion under intellectual property protection has become the important impetus to the economic growth. However, the present intellectual property suffers from low protection and weak law enforcement intensity, the situation undermines China’s absorption of FDI technology spillovers and weakens the contributions of foreign technical overflow to China’s technological progress.
