Double Measurement of Foreign Trade Comparative Advantage in Sino-US High-tech Industry Under Intra-product Specialization

Abstract

Since China developed technology, its exports of high-tech products increased rapidly. Whether trade comparative advantage in China is reversal? Is export structure optimized? This paper measure the revealed comparative advantage (RCA) of technology of China and the U.S., and measure the export domestic added value comparative advantage (AVCA) based on non-competitive input-output model. The results show that China’s RCA has increased except special industries; the RCA exceed the U.S. in some technical industries; while the domestic value added coefficients are always less than American; compared with the U.S., RCA of different technologies after adjustments has decreased significantly in China
