The impact of the U.S. tariffs imposed on #美国加征关税 is profound and complex. In the short term, tariffs have raised the prices of imported goods, increasing the burden on American consumers, and may slow GDP growth by 0.4% to 1.5%. For China, export obstacles may suppress economic growth by 0.3 to 0.4 percentage points and exacerbate deflationary pressures. The global supply chain faces restructuring, with companies forced to shift production capacity, but declining efficiency and rising costs may weaken competitiveness. In the long term, tariffs could escalate the risk of trade wars, leading to the fragmentation of the global economy and undermining the multilateral trading system. U.S. auto companies and other industries have already been hit hard by rising costs and shrinking demand, resulting in a significant drop in profits.
