外资大规模流入美国,既是美国实施宏观经济政策的结果,也与美国各级政府在微观政策上力求改善投资环境有关。外资可促进美国增长,增加就业机会,提高劳动生产率;同时也给美国带来不利影响。 Large-scale inflow of foreign capital into the United States is not only the result of the implementation of macroeconomic policies in the United States, but also the improvement of the investment environment by the U.S. governments at all levels in their micro-policies. Foreign investment can promote the growth of the United States, increase employment opportunities and increase labor productivity, as well as adversely affect the United States.
