The ratio of R&D investment to GDP is a measurement for a country’s research ability. Given the GDP and total value of imports and exports, this paper shows that the higher the ratio of R&D investment to GDP is, the larger the ratio of the value of imports and exports of high-tech products to the total value of imports and exports gets, and the more competitive advantage the high-tech firms have. This paper also investigates that the mass increase of scientific and technical personnel may decrease the level of export-oriented R&D investment. So far the literature about R&D investment as viewed form export market orientation is rare.
