WTO前首席经济学家：美元或提前失去主导地位

Group 1: Economic Impact of Tariffs - The direct effect of tariffs may reduce the U.S. economic growth rate by 0.5% to 0.75%, with a negative impact of approximately 0.1% on global economic growth [5] - Tariffs are expected to raise commodity prices and increase the cost of production components, affecting both domestic production and global exports [3][5] - The uncertainty surrounding tariffs and international relations has led many domestic and foreign companies to postpone significant investments, which may have a more substantial impact on U.S. economic growth than the tariffs themselves [3][5] Group 2: U.S. Trade Policy and Global Trade Dynamics - The U.S. trade policy under the Trump administration is characterized by aggressive unilateral actions, which may lead to long-term damage to global trade relationships [6][8] - The potential for a restructuring of global trade networks is anticipated, similar to past global shocks, although this may slow down globalization rather than reverse it [6][8] - The U.S. may not fully withdraw from the WTO but could adopt a less active role, which might encourage other member countries to push for rule reforms [9] Group 3: Future of the Dollar and Global Currency Dynamics - The dollar is expected to maintain its dominant position for the next 10 to 20 years, but its supremacy may be challenged due to U.S. fiscal imbalances and concerns over investment safety [10] - The uncertainty surrounding U.S. fiscal policy and the safety of U.S. debt could weaken the dollar's status in the global economy [10][11] Group 4: WTO Reform and Global Trade Rules - There is a pressing need for WTO rule updates to address new global challenges such as climate change and health crises, as current rules do not adequately reflect these issues [8][9] - The cooperation of major economies, including the U.S., China, and the EU, is essential for establishing a new, acceptable rule system within the WTO [9][12]
