| FDI technology spillover divides into inner-industry and inter-industry spillover. FDI Inter-industry technology spillover reflects on that impartial backward and forward relation which foreign investments brings, which is also described that foreign business could supply better middle products and make the users industry enhance the productivity, or foreign business enhance the productivity of the industry which provide middle products for it as the products users. Although according to the theory, when international manufacture industry capital transfer into one country, it would bring the demands of industry linkage for the native business and the native business can have the chance of technological learning to improve technological ability, however, the inter-industry technology spillover effect between the international transfer capital and native industry need further research.The article research the important way in which inter-industry technology spillovers—industry connection, containing backwards and forwards relationships first in the theory analysis, and also considers foreign and native business's industry linkage as an important style of the industry connection. The article elaborates many factors affecting the inter-industry technology spillover effect at last.When selecting industry department to do empirical analysis, the article uses the main component analysis method and Shang Hai industry department data to determine Shang Hai pillar industry which conforms to the fact. Then according to the industrial chain of the leading products in the traffic and transportation equipments manufacture industry, electronic communication and computer manufacture industry, and general equipment manufacture industry. Considering about production matching radius factor, the article finds the pillar industry's matching industry department. At last, every inspected industry's FDI proportion is also studied so that the article selects the final industry department to do empirical analysis and finds the research's theory basic.The article's empirical analysis uses panel data type and GMM methods, improves and revises the existing econometrics model, and last concludes from the results that: we find the inter-industry forward technology spillover effect is notable, but the inter-industry backward technology spillover effect is not notable, which is the same conclusion as the other paper. But this paper selects pillar industry and its supporting industry as the empirical objects, and even draw into the variables inspecting R&D investment for the model, so that the results get different from capital-co notated technology spillover angle. The econometrics results prove that backward technology spillover effect become notable, and it is positively related; which proves that the increase of the pillar industry R&D investment can promote the native matching industry's output value and product efficiency, the FDI pillar can promote the native matching industry's technology advance. Forward technology spillover effect become notable, but it is negatively related; which proves that although lots of foreign manufacture industry capital with high technology level and product efficiency transfer into native country, the technology level of the native matching industry is still low, only support the foreign manufacture industry capital with elementary inputs. The econometrics results also give the elastic value of FDI R&D investments in the forward and backward technology spillover. |
