解构美国系列第十三篇：减税法案顺利落地，可以对冲关税压力吗？

Group 1: Tax Reform Overview - The tax reform primarily extends existing tax cuts from the 2017 tax reform, with a limited incremental scale of approximately $4.5 trillion over the next ten years, while new tax relief measures amount to only $0.7 trillion[3] - The tax reform focuses on individual tax cuts, with an estimated reduction in tax revenue of about $4.2 trillion for individual taxes compared to $1.1 trillion for corporate taxes over the same period[4] - The U.S. government deficit is projected to increase by approximately $4 trillion over the next decade due to the tax reform, despite potential increases in tariff revenues[5] Group 2: Economic Impact - The tax reform is expected to partially offset the economic pressure from tariffs, potentially alleviating recession expectations in the U.S. economy[2] - The Congressional Budget Office (CBO) estimates that the tax reform could increase U.S. GDP growth by an average of 0.5 percentage points from 2025 to 2034, while tariffs are projected to decrease GDP growth by 0.6 to 0.8 percentage points[14] - The distributional effects of the tax reform indicate that the bottom 10% of low-income households may see a decrease in disposable income by about 2% by 2027, while the top 10% may benefit from an increase[15]
