Abstract: This paper illustrates the transmission mechanisms of imports in services influencing growth of TFP, empirically researches the effect of imports in services on TFP with data for China and OECD, calculates the optimal strength of IPRs for TFP growth, and draws conclusions as follows. Firstly, labor-intensive and capital-intensive imports in services don’t contribute to TFP growth, but technology-intensive imports in services promote TFP growth significantly, and these results keep constant when IPRs are taken into consideration. Secondly, the currently actual strength of IPRs in China is lower than the optimal strength of IPRs needed by domestic R&D and technology-intensive imports in services, but it’s the opposite case in OECD. Thirdly, the optimal strength of IPRs needed by domestic R&D is lower than that needed by technology-intensive imports in services.
