其他摘要:Anti-dumping (AD) investigations are widespread since early 1990s. However, the situation re-cently is quite different from that observed early. This paper focuses on the assessment of the new AD phe-nomenon and its historical development based on a self-constructed global antidumping database during 1981-2008. We discuss the time pattern of adoptions of AD laws and initiations of AD filings, the different roles played by the developing and developed countries, countries’ asymmetric position being a plaintiff and defendant as well as industrial concentration and some other characteristics of antidumping proliferation. The policy implications are drawn based on the statistics pertaining to the worldwide caseload.
