Intellectual Property Protection, FDI and the R & D Innovation Total Factor Productivity---Empirical Research on Chinese Regional High-tech Industry
Based on Malmquist index and DEA model , this paper calculates the R&D innovation TFP of Chinese regional high-tech industry from 2000 to 2012;taking IPP , FDI and R&D TFP innovation in a uniform framework , it investigates the influence of IPP , FDI on R&D innovation TFP index and its decomposition of Chinese high-tech industry . The research results show that:the R&D innova-tion annual TFP growth is 6.3% , and the main driving force is technological progress;there are significant differences in the regional IPP level;the regression results show that:IPP has a significant role in promoting the R&D innovation TFP , FDI shows a significant negative spillover effect , and the interaction of IPP and FDI also has a significant positive effect .
