美国是世界上最大的发达国家，基础设施相对完备。无论是与自身发展的历史比较，还是与其他国家比较，当前美国基础设施的品质与规模都发展到了一个较高阶段，处于世界领先水平。但同时，美国的基础设施也存在老旧失修、结构与分布失衡的问题，并且气候变化的风险与科技创新的发展不断对美国基础设施建设提出更高需求。因此，特朗普政府曾先后两次将基础设施建设列为其执政重点，并推出“万亿基础设施计划”。由于近期受到国内政治博弈、政策惯性等因素的牵制，该计划不得不在目标与能力之间寻求平衡。
The United States is the largest developed country in the world with relatively complete infrastructure. No matter compared with the history of its own development or other countries，the quality and scale of infrastructure in the United States have reached a relatively high level，leading the world. At the same time，however，the U.S.infrastructure suffers from big problems such as old and unbalanced systems，and climate change risks and technological innovation also require higher developments on infrastructure in the United States. Therefore，the Trump administration has twice listed infrastructure investment as one of his priorities and launched the trillion-dollar infrastructure investment proposal. Due to the domestic political game，policy inertia and other factors，Trump has to find a balance between goals and capabilities when rebuilding the U.S.infrastructure.
