针对人民币汇率低估导致中美贸易不平衡和日益严峻的贸易战和汇率战风险等问题，本项目以美国汇率与贸易法案投票为研究对象，在汇率政策政治经济学和贸易政策政治经济学的理论框架下，以人民币汇率波动对美国汇率与贸易法案投票的影响机理和汇率-贸易-就业-投票的传导机理为研究主线，以“保护待售”经典模型为研究基础，纳入异质性劳动力市场出清条件和汇率因素，系统研究如何从理论上阐释汇率对投票的影响和传导机理，实证检验人民币汇率波动对美国汇率与贸易法案投票的影响和传导机理，以及再检验外生政策冲击下人民币波动对美国汇率与贸易法案投票的影响机理等科学问题。从理论建模、实证检验、外生政策冲击下的实证再检验三个方面阐明人民币汇率波动对美国汇率与贸易法案投票的影响和传导机理，为中国制定汇率政策和贸易救济政策、解决中美贸易不平衡、化解中美贸易摩擦与冲突等问题提供理论参考和政策建议。

With regard to Sino-US trade imbalance and the growing trade and currency war risk due to undervalued RMB, this research studies the voting of exchange rate and trade act under the theoretical framework of political economics of exchange rate policy and trade policy. By following the influence mechanism of RMB exchange rate volatility towards voting of exchange rate and trade act and the transmission mechanism of the exchange rate - trade - employment - voting as main research lines, based on the classical model “protection for sale”, this research takes into consideration the heterogeneity of labor market clearing conditions and exchange rate factors, and systematically studies the scientific issues on how to explain the influence and transmission mechanism of RMB exchange rate volatility on voting theoretically, how to test the influence and transmission mechanism on voting empirically, and how to retest influence mechanism of RMB exchange rate volatility on voting under exogenous policy shock. From theoretical modeling, empirical tests, and retesting under exogenous policy shock, this research tries to illustrate the influence and transmission mechanism that RMB exchange rate volatility influences voting in the United States, in order to offer theoretical references and political suggestions on issues such as implementing foreign exchange rate policies and trade remedy policies for China, addressing the Sino-US trade imbalance and resolving Sino-US trade frictions and conflicts for Chinese government.
