反补贴已经成为WTO成员间贸易摩擦热点,产业损害是反补贴调查的重要内容,而产业损害幅度的确定是产业损害认定的核心问题。本文基于反事实分析与主成分分析方法,运用管理统计学与计量经济学模型,构建反补贴产业损害确定的FC(Factor analysis and Counterfactanalysis)组合分析法。同时,结合2006年中美铜版纸案件进行实证研究并得出相应结论,以期给我国进口反补贴调查机关在实施进口反补贴措施中的产业损害确定提供现实借鉴。 Countervailing has become a hotspot in the trade frictions among WTO members. Industry damage is an important part of anti-subsidy investigations. The determination of the magnitude of industrial damage is the core issue of industrial damage identification. Based on the counterfactual analysis and the principal component analysis, this article uses the combination of management statistics and econometrics models to construct a combined analysis method of FC (Factor analysis and Counterfactoralal analysis) to determine the damage of countervailing industries. At the same time, the empirical research on China-US joint-stock paper in 2006 was carried out and the corresponding conclusions were drawn. It is hoped that this will provide a practical reference for the determination of China’s import countervailing duty investigation agency in the implementation of import anti-subsidy measures.
