| Under the background of fast development of economy, technological innovation ability of a country has become the most important factor for the national competitiveness. Demand-induce theory indicates that market demand supplys opportunities and thoughts for technological innovation. In global economy, the demand factors conclude demestic demand as well as export. Export provides a more intense competition platform for enterprises, and international competition could encourage innovation. Technology spillover produced in the process of export could also influence technological innovation ability. Meanwhile relative policies of export and import countries are helpful to the explanation of export induced innovation. Recently, researches on the promotion of innovation ability which are from the view of demand have been concerned by scholars, but effects of export on technological innovation are slightly studied. So this article analyzes this promblem mentioned above in order to give some thoughts for further researches.On the base of literature review, this article summarizes the mechanisms of export influencing on innovation as competition effects, technological spillover and policy influence, and then this paper estimates the effects of export on technological from country level. At the same time the effects of related policy on innovation investment are tested by data of large and medium-sized industrial enterprises. The empirical results indicate that China's export does do good to technological innovation, but it is less than domestic market. Difference of economic development, industrial structure, opening degree and so on make different export-induced innovation. Moreover, government export rebate policy can promotes enterprises to carry on the research and development (R&D) activities while innovation subsidies policy has opposite effects on R&D investment and innovation level, which states subsidies policy is lack of stability and should be enhanced. |
