Specificity is one of the most important concepts in SCMagreement. According to Article 1.1of the agreement，subsidy is a financial contribution conferred to any specific enterprises through the government or public agencies of the government of a Member state. Furthermore，Article 1.2 of the agreement provides that a subsidy is subject to the regulation of the agreement only if such subsidy is specific . The countervailing law is directed to specific subsidies，as they may render distortion in the allocation of resources and unfair competition . Consistent with the historical origin of this term，the specificity test under SCM agreement is enacted to restrict the possible abuse of countervailing duty measures. AccordingtotheU.S.Commerce Department'scountervailinginvestigationsontheimports from China in recent years and the application of specificity test in these investigations，as SCM agreement requires that a determination of specificity must be clearly substantiated on the basis of positive evidence， meanwhileU.S. DOCadoptsthe “adverseinference”ruleinitsspecificitytest，thepracticesofU.S.DOC is not consistent with the SCM agreement and result in the unlawful determinations on the specificity of subsidies .
