反倾销是美国最频繁使用的贸易保护措施。在当前背景下，中美贸易战一触即发，作为中国最大的贸易伙伴--美国，中美贸易战将会使中国出口企业在美国市场上面临一系列严峻的挑战。本研究将通过构建理论模型，并运用中国海关贸易数据，理论及实证分析中国多元产品出口企业如何应对美国反倾销贸易保护措施。具体包括中国多元产品出口企业在美国反倾销后如何调整其非反倾销产品出口的品种数量、出口数量及价格；反倾销后，多元产品出口企业应如何在其非反倾销产品中重新配置资源，改变其非反倾销产品的出口组合及结构，以达到利润最大化目标。本研究在当前中美贸易形势下是非常迫切急需的，而且该研究结果将对中国多元产品出口企业具有很好的现实指导意义；同时，本研究也将对贸易研究领域、反倾销研究领域具有一定的理论贡献。

Antidumping is one of most frequently used trade protection measures by United States. After Donald Trump became the President of US, the trade environment of US-China is getting worse. Trade war between two countries is about to break out. At that time, Chinese exporters will face huge challenges from US trade protection measures. This study will build up a partial equilibrium model to study the behavior of the multi-product exporters when they face antidumping tariffs. Moreover, we will empirically estimate how Chinese multi-product exporters response US antidumping by using the Chinese Customs Data,especially,how to adjust or reallocate resources of antidumping product to non-antidumping products within firm. This study is imperative and urgent due to present trade environment change between US-China. The research results of this study will also be of directive significance to Chinese multi-product exporters. Meanwhile, this study also has significant contribution to trade literature.
