The Empirical Analysis Of Spillovers Through International Trade Of China

Development economists believe that the economic growth of one country depend on accumulate of the capital and technology progress; the latter compose core competition capacity in country' s developing. Technology progress of one country relies on domestic R&D capital stocks and the absorption of R&D spillovers. The channels of R&D spillovers include international trade, FDI, international R&D cooperation.This paper measures the influence of R&D spillovers through International trade to China' s economy growth, bases on trade spillovers model of Coe & Helpman. The results indicate that whether with or without FDI, R&D spillovers through international trade do push China' s growth, and the output elasticity in the latter case is smaller than the former one. There exists inter-linkage between FDI and international trade on R&D spillovers, but the effects of FDI couldn' t substitute for the one of international trade completely.The determinants or R&D spillovers through international trade involve the difference of trade country and industry. It' s obviously R&D spillovers come from industrialized counties are more important than the others. R&D spillovers changes with technology gap in reverse directions. It displays China had step over the sill of development; It' s hard to judge whether the openness is good to R&D spillovers, so the free trade policy isn' t the best and omnipotent choice.
