Abstract:US President Joe Biden signed into law the Infrastructure Investment and Jobs Act,starting a new round of largescale infrastructure building in the United States. Biden’s team calls it a“once-in-a-generation investment”in American infrastructure and competitiveness, which will determine whether the US can win“the competition of the 21 century.”Biden’s infrastructure plan includes two parts: Build Back Better domestically and Build Back Better World globally. It attempts to improve national competitiveness and restore the foundation of American hegemony by coordinating short-term and long-term goals,soft and hard infrastructure,and internal and external layout.So far,there is a big gap between Biden’s ambitious infrastructure plan and its implementation.Political obstacles are the biggest problem with Biden’s infrastructure plan.
