| FDI means the foreign direct investment, it is direct investment into production or business in a country by an individual or company of another country. FDI technology spillover effect specifically expression in foreign direct investment in the external performance. After the investment of the multinational corporation, they will through the form of technical guidance and training or domestic enterprises interactive way to make their own advanced production, management and marketing ect technology, knowledge or experience spread to those close contact domestic enterprises indirectly. So that effect the host country technical efficiency and economic growth. Based on endogenous growth theory and foreign investment theory, FDI will-cause the host country technological progress, have a positive impact on economic development, namely the existence of technology spillovers.However, the Empirical Analysis shows that it is not necessary for FDI produce technology spillover effect. The existence of FDI spillovers effects have been questioned and qualitative differences in different countries, even same countries in different regions and different industries.Through the analysis of FDI technology spillover effect about central concepts, theoretical root, overflow mechanism and influencing factors,the reasons for the heterogeneity of spillover effect results, besides the differences in perspective, research method and sample data, is to ignore the industry level of diversity. As a clue to find relevant literature on industrial diversity and divided itinto two aspects,namely related diversity and unrelate diversity, according to the technical relations among industries then put forward hypothesis:on one hand, by increasing the degree of industrial agglomeration area, building industry association rationalize and increasing mutual cooperation between the regional industry, related diversity ensures the smooth flow of overflow and total overflow channel technology and improve FDI technology spillover effect; on the other hand, unrelated diversity has the role of maintaining regional stability only, because separates the industrial relations between different industries, hindered the knowledge, technology and personnel flow, the FDI spillover channels of domestic sector, resulting in negative regulation effect on technology spillovers effect. Because there is a positive correlation between the level of regional science and FDI technology spillover effect, we puts forward the hypothesis that in thehigher level of science and technology, related and unrelated diversity diversity has more positive and negative regulatory role on FDI technology spillover effect Then, we collect the Bohai Economic Zone59cities in2003and2011totallynine years’ data and use Eviews6.0analysis software for empirical analysis.Finally, the empirical results of the Bohai Sea economic zone verify the existence of FDI technology spillover effect on the Bohai Economic Zone, and the relevant diversity has a moderating effect on FDI technology spillover effect, rather than diversity has negative effect on FDI technology spillover effect. FDI technology spillover effect in different science and technology level is different, as well as related and unrelated diversity regulation, showes that in high technology environment, related and unrelated diversity on FDI technology spillover effect of positive and negative regulatory effect is very significant, and the regulating role both in low the technical level of environment is not obvious. According to the empirical results of the Bohai Sea Economic Zone, we put forward the following three suggestions from the perspective of industrial structure:(1)The industrial regulatory mechanism is proceeded with market-oriented transformation.(2)The area’s absorptioncapacityof FDI spillover technology effect is enhanced by using the related diversity.(3) The policy in unrelated diversity area should promote the guidance of establishing interactions and platforms between these unrelated industries. |
