| To improve the indigenous innovation capacity and to build China into an innovative country is the national strategy at present. In the open economy, the level of a country's technological innovation capacity depends on not only the endogenic innovation but also the second innovation based on the exogenesis technology. By now, the researches on the spillover effects of FDI have mainly focused on the host country's labor productivity or total factor productivity from the perspectives of regions and intra-industry by the domestic and foreign scholars. However, researches from the perspectives of inter-industry are rarely found, especially for the spillover effect of FDI on technological innovation in the host country. China is now the largest developing country all over the world. Successfully attracting FDI to improve the indigenous technological innovation capacity is the final target of success for open policy. So the researches on the spillover effect of FDI on technological innovation in China make sense in both academic and practical means.Based on the related literature, my research is based on such a framework as follows: firstly, we investigate the relationship between FDI and indigenous technological innovation in China, then, the spillover effects of FDI on innovation and the influencing factors, and the working mechanism of FDI on technological innovation at last. The data sourcees of the thesis are mainly from the china statistical yearbook on science and technology and china statistical yearbook from the year1998-2006, the data of export of industry product is from china industry economy statistical yearbook. The main contents and results of this research are listed as follows:1. The relationship between FDI and technological innovation in China.Using the method of Paired-Sample Test, the differences of technological innovation between MNCs and local enterprises is analyzed. The result shows that, compared with MNCs, the scales of local enterprises are larger but the technical levels are lower; the input for innovation is at higher level, while the R&D capacity is lower and the innovation output and performance are at a lower level. Therefore, as a whole, the technological innovation capability of local enterprises falls behind that of foreign capital enterprises. Which is the basis for spillover effect of FDI. Moreover, by the analysis of co-integration and Granger Causality Test, time series model was used to study the relationship between FDI and indigenous innovation. The results show that, there is long-run stable relationship between FDI and indigenous innovation and FDI is the Granger cause for indigenous innovation. These results demonstrate that the spillover effect of FDI on innovation in China is positive.2. The existence of spillover effects of FDI on innovation in China.From the perspectives of regions, intra- industry and inter-industry, the spillover effects of FDI of the same period and the delay period on innovation in China is both studied using panel data. Because the stock index is applied in the calibration of FDI, the spillover effects of FDI of the delay period is not significant and is less than those of the same period. Therefore, the model for the spillover effects of FDI of the same period is more interpretative. The studies show that, expenditures on science and technical development have a positive effect on the technological innovation in China while the effect of the number of personnel for science and technical development is not significant .So, the expenditures on science and technical development is the key factor for the developing of technological innovation in China.Empirical analysis shows, no matter from the perspective of region level or industry level, FDI has positive spillover effects on the technological innovation in China. From the perspective of region level, FDI has positive innovative spillover effects; from industry level, the vertical spillover effects of FDI on technological innovation are significant while the horizontal effects are not. So, the spillover effect of FDI in China is mainly by the means of industry linkages. The study on vertical spillover effects of FDI indicates that: when the sales income of new product is deemed as explanatory variable, backward spillover effects are significant while the forward effects are not; when the patent application amount is explanatory variable, both backward and forward spillover effects are significant. So, the vertical spillover effects of FDI vary with the different side of innovation.From the perspective of personnel and production, innovation spillovers channels of FDI are studied, which are also the important factors, affecting the innovation spillovers of FDI. At the same time, this paper studied the characteristics of innovation spillovers from different regions and industries further. In different regions, the differences of innovation spillover of FDI in China are little: despite of the distinct differences between east and middle China, the differences of eight economic regions are not significant and those of the regions divided by innovation capability and absorption capability are not either. As for the supplier-dominated sectors, scale-intensive sectors and process innovation-predominant industry, the backward spillover effects are significant while the horizontal effects and forward effects are not; as for the specialized suppliers sectors, the forward spillover effects are significant while the level effects and backward effects are not; as for the science-based sectors, the backward spillover effects are significant and the level effects are negative; as for the product innovation oriented industry, both the horizontal and vertical innovation spillover effects are not significant.3. The influencing factors of spillover effects of technological innovation of FDI.We treat the influencing factors as pseudo variable to build panel data model, these influencing factors of spillover effects on innovation of FDI are studied from the levels of regions and industries. The studies on regional level show as follows: the effect of the regional economic level are not significant; the effect of human capital is significant at the level of 10%; the effect of opening up is significant at the level of 5% ; while the effect of earlier policy for opening up are not; the effect of traffic and telecommunications infrastructure are significant. at the level of 5%. So, broadening opening up, reinforcing the level of infrastructure and improving the level of human capital are good for the spillover effect of FDI on innovation.The studies on intra-industry innovation spillover effect of FDI shows that, technology gap of local and foreign enterprises, capital intensity gap, quality gap of R&D human capital and technological innovation gap are not beneficial to the innovation spillover of FDI; the quality of R&D human capital of domestic capital enterprises and the level of technology innovation, the level of appropriability of innovation, export-orientation of foreign capital enterprises and export gap of domestic and foreign enterprises significantly improve the intra-industrial innovation spillover of FDI. The studies on inter-industry innovation spillover effects of FDI shows, the level of backward linkages are not significant; while the level of forward linkages are significant and positive; export-orientation of domestic and foreign capital enterprises is not significant to the vertical innovation spillover effects of FDI; the industrial opening degree and market competition have negative effects on the vertical spillover of FDI and have positive effects on the forward spillover of FDI.4. The action mechanism of FDI on the technological innovation capability in China.We carry out Empirical Study with FDI from HMT, other countries and FDI in general on the Innovation Capacity of state-owned and controlled enterprises, domestic enterprises from the perspectives of region and industry separately. Empirical analysis shows, Different Sources of FDI's Spillover effects on the innovation capacity of state-owned and controlled enterprises is larger than that of domestic enterprises', so the absorption capability of the state-owned and controlled enterprises is larger. The Spillover effects of FDI from HMT on the innovation capacity in China is lower than that of FDI from other countries', so the researches with the conclusion that FDI has positive spillover effects on innovation capacity in China may conceal the fact that the Spillover effects of FDI from HMT is no significant.FDI can facilitate the innovation input, R&D capability, innovation output and innovation performance of local enterprise. The innovation inputt has the mediating effects on the facilitating process of FDI to R&D capability and innovation output of local enterprise; The R&D capability has the mediating effects on the facilitating process of FDI to innovation output and innovation performance of local enterprise; The innovation output has the mediating effects on the facilitating process of FDI to innovation performance of local enterprise.
