This article incorporates foreign direct investment (FDI) and product diffe
rentiation in a general equilibrium trade model. The analysis shows that fr
eer trade and FDI will upgrade China's technology, improve its skills of la
bor, and increase the competitiveness of local firms in the international m
arket. At the same time, the relative wage of skilled labor to unskilled la
bor will rise. The size of this rise will be affected by the degree of prot
ection for intellectual property rights. These theoretical results are cons
istent with empirical evidence. The analysis provides insights in coordinat
ing policies on FDI, labor market reform, and intellectual property rights
protection. (C) 2001 Elsevier Science Inc. All rights reserved.
