Study on the Impact of U.S. High Tariffs on China and the Game Strategies of Export-oriented Enterprises in the Yangtze River Delta Region

This paper examines the effects of U.S. high tariffs on China's export-oriented firms in the Yangtze River Delta, revealing severe impacts since 2018 due to the trade war. The region, vital to China's export economy, faced heightened costs and trade shifts, prompting firms to adapt through market, industrial, technological, and supply chain strategies.Drawing on case studies, comparative regional analyses, and policy evaluations, the paper proposes a comprehensive four-dimensional strategy: expanding into emerging markets under the Belt and Road Initiative; leveraging precise policy tools to mitigate tariff burdens; integrating the domestic and international “dual circulation” economic model; and driving innovation to reduce costs and enhance efficiency. The research aims to support policy formulation and offer strategic insights to strengthen export firms’ competitiveness and sustainability. Ultimately, the study provides a practical framework for enterprises to shift from passive reaction to proactive breakthrough in the face of global trade reordering.
